An online pet store ships two cases of dogs and four bags of treats the dog food weighs 13 1/2 ounces per camp and there are 12 cans in the case the dog treats are shown right and evaluate an expression to show the total weight of the items

Answers

Answer 1

The total weight of the items is 29.25 lb.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The wight of one can = 13 1/2 = 27/2 pounce

and, number of cans in one case = 12

So,  total weight of the items

= 1/16 ( 27/2 x 12 x 2)+ 4x 2.375

= 1/16 ( 324) + 9.5

= 81/4 + 9.5

= 20.25+ 9.5

= 29.25 lb

Hence, the weight is 29.25 lb.

Use the binomial series to expand the following function as a power series. Give the first 3 non-zero terms. h(x)= 1 / [(3+x)^(8)]

Answers

The first 3 non-zero terms are h(x) = 1/6561 - (8/2187)x + (36/10935)x^2

We can use the binomial series formula (1 + x)^m = 1 + mx + m(m-1)/2! x^2 + ... to expand h(x) as a power series:

h(x) = 1 / [(3+x)^8]

= (3+x)^(-8)

= (3(1 + x/3))^(-8)

= 3^(-8) * (1 + x/3)^(-8)

Using the binomial series formula with m=-8 and x/3 as the value of x, we have:

h(x) = 3^(-8) * [1 + (-8)(x/3) + (-8)(-9/2)(x/3)^2 + ...]

To expand the function h(x)= 1 / [(3+x)^(8)] as a power series using the binomial series, we start by using the formula (1+x)^n = 1 + nx + n(n-1)x^2/2! + n(n-1)(n-2)x^3/3! + ... , where n is a positive integer. We can rewrite h(x) as h(x) = (3+x)^(-8) and substitute -x/3 for x, giving us h(-x/3) = (1-x/3)^(-8).

We can then use the binomial series to expand (1-x/3)^(-8) as a power series, which is given by 1 + 8x/3 + 36x^2/9 + ... . Therefore, the power series for h(x) is given by h(x) = 1 / [(3+x)^(8)] = (1-x/3)^(-8) = 1 + 8x/3 + 36x^2/9 + ... . The first 3 non-zero terms are 1, 8x/3, and 4x^2/3.
To expand h(x) = 1 / [(3+x)^(8)] using the binomial series, we apply the binomial theorem for negative powers. The general formula for a binomial series with a negative power is:

(1 + x)^(-n) = 1 - nx + n(n+1)x^2/2! - n(n+1)(n+2)x^3/3! + ...

In our case, n = 8, and x = -x/3. So, we have:

(3 + x)^(-8) = (3(1 - x/3))^(-8) = (1 - (-x/3))^(-8)

Applying the formula:

h(x) = 1 - 8(-x/3) + 8(9)(-x/3)^2/2! - ...

Now, simplify the terms:

h(x) = 1 + 8x/3 + 36x^2/9 + ...

a student states: ""adding predictor variables to a multiple regression model can only decrease the adjusted r2."" is this statement correct? comment.

Answers

While adding predictor variables to a multiple regression model can potentially decrease the adjusted R², it can also increase it if the added predictors contribute significantly to the explained variance. The statement is not entirely correct.

The statement "adding predictor variables to a multiple regression model can only decrease the adjusted R²" is not entirely correct. Let me explain why:
When you add a predictor variable to a multiple regression model, the R² value, which represents the proportion of the variance in the dependent variable that is explained by the predictor variables, may increase or stay the same. However, it cannot decrease.
The adjusted R², on the other hand, takes into account the number of predictor variables in the model and adjusts the R² value accordingly.

As we add more predictors, there's a chance that the adjusted R² may decrease if the additional predictors do not contribute significantly to the explained variance.
However, it is not true that adding predictors can "only" decrease the adjusted R².

If the added predictor variables provide substantial power and improve the model, the adjusted R² can increase.

The student's statement that "adding predictor variables to a multiple regression model can only decrease the adjusted R2" is not entirely correct.

While it is true that adding irrelevant predictor variables can decrease the adjusted R2, adding relevant predictor variables can increase or at least maintain the adjusted R2. This is because the adjusted R2 measures the goodness of fit of a regression model, taking into account the number of predictor variables and sample size. Therefore, if the added predictor variable has a significant relationship with the dependent variable, it can improve the model's ability to explain variance and increase the adjusted R2.

In summary, the effect of adding predictor variables on adjusted R2 depends on their relevance to the dependent variable and the existing predictor variables in the model.

Answers

The 95% confidence interval for the difference between the proportions of Californians and Oregonians who are sleep deprived is approximately (-0.0354, -0.0006).

To calculate the 95% confidence interval for the difference between the proportions of Californians and Oregonians who are sleep deprived, we can use the formula:

Confidence Interval = (p1 - p2) ± Z × √((p1 × (1 - p1) / n1) + (p2 × (1 - p2) / n2))

Where:

p1 is the proportion of California residents who reported insufficient rest or sleep

p2 is the proportion of Oregon residents who reported insufficient rest or sleep

n1 is the sample size for California

n2 is the sample size for Oregon

Z is the Z-score corresponding to the desired confidence level (95% confidence level corresponds to Z = 1.96)

Given:

p1 = 0.073 (7.3%)

p2 = 0.091 (9.1%)

n1 = 11630

n2 = 4387

Z = 1.96 (for 95% confidence level)

Let's calculate the confidence interval:

Confidence Interval = (0.073 - 0.091) ± 1.96 × √((0.073 × (1 - 0.073) / 11630) + (0.091 × (1 - 0.091) / 4387))

Confidence Interval = -0.018 ± 1.96 × √((0.073 × 0.927 / 11630) + (0.091 ×0.909 / 4387))

Confidence Interval = -0.018 ± 1.96× √(0.000058 + 0.000021)

Confidence Interval = -0.018 ± 1.96 ×√(0.000079)

Confidence Interval = -0.018 ± 1.96× 0.008884

Confidence Interval = -0.018 ± 0.017418

The 95% confidence interval for the difference between the proportions of Californians and Oregonians who are sleep deprived is approximately (-0.0354, -0.0006).

Note: The negative value indicates that the proportion of Oregonians who are sleep deprived is higher than the proportion of Californians.

What is the annual value you of this job to Brenda

Answers

The annual value of Brenda's job can be calculated by considering her base salary and the contributions made by the company towards her insurance costs.

By determining the total annual contributions towards insurance and adding them to Brenda's base salary, we can find the annual value of her job. To calculate the annual value of Brenda's job, we first need to determine the contributions made by the company towards her insurance costs. The company pays for 1/4 of the cost of medical insurance, which amounts to (1/4) * $350 = $87.50 per month or $87.50 * 12 = $1050 per year. Similarly, the company pays for 1/2 of the cost of dental insurance, which amounts to (1/2) * $75 = $37.50 per month or $37.50 * 12 = $450 per year.

As for vision insurance, the company covers the full yearly cost of $120. Additionally, the company covers the full monthly cost of life insurance, which amounts to $20 * 12 = $240 per year.

To calculate the annual value of Brenda's job, we add up her base salary of $450 per week, the contributions towards medical insurance ($1050), dental insurance ($450), vision insurance ($120), and life insurance ($240). Therefore, the annual value of Brenda's job is $450 + $1050 + $450 + $120 + $240 = $2310.

When interpreting F(2,27) = 8.80,p < 0.05,what is the within-groups df?
A)30
B)27
C)3
D)2

Answers

The degrees of freedom (df) for the within-groups scenario is 27.

In the F-test, which is used to compare variances between groups, the degrees of freedom consist of two components: the numerator df and the denominator df. The numerator df corresponds to the number of groups being compared, while the denominator df represents the total number of observations minus the number of groups.

In the given scenario, F(2,27) = 8.80 indicates that the F-test is comparing variances between two groups. The numerator df is 2, representing the number of groups being compared.

To determine the within-groups df, we need to calculate the denominator df. The denominator df is calculated as the total number of observations minus the number of groups. Since the denominator df is given as 27, it implies that the total number of observations is 27 + 2 = 29, considering the two groups being compared.

Therefore, the within-groups df is 27, as it represents the total number of observations minus the number of groups in the F-test.

In conditional probability, we calculate the probability of an event and it is known that the other event has already occurred.

In case of independent, the probability of one event can't be effect the probability of a 2nd event, that is Probability of intersection of two events is product of individual probabilities

From the definition of conditional probability, for independent events A and B, P( (A∩B)| C) = P( A|C) P( B|C)

Observe that 3 3 ? 2n2 2n2 + 3n + 5 because the left side has a bigger denominator. (In the notation of the Comparison Test, an is the left side and bn is the right side.)

Answers

Since the series Σ 3/(2n^2) is a convergent p-series with p = 2 > 1, and since 3(2n^2 + 3n + 5) < 2n^2 for all n beyond some point N, we can conclude that the series Σ 3(2n^2 + 3n + 5) is convergent by the Comparison Test.

To determine whether the series Σ 3(2n^2 + 3n + 5) converges or diverges, we can use the Comparison Test.

First, we observe that for large n, the dominant term in the denominator is 2n^2. Therefore, we can compare the given series with the series Σ 3/(2n^2).

Next, we want to show that 3(2n^2 + 3n + 5) < 2n^2 for all n beyond some point N. To do this, we can simplify the inequality as follows:

3(2n^2 + 3n + 5) < 2n^2

6n^2 + 9n + 15 < 2n^2

4n^2 - 9n - 15 > 0

(n - 3/2)(4n + 10) > 0

Therefore, for n > 3/2, we have 4n^2 + 10n > 3(2n^2 + 3n + 5), and so 3(2n^2 + 3n + 5) < 2n^2 for all n beyond N = 3/2.

Answers

To find the values of m for each case, we need to analyze the given vectors. For case (a), m can be either 1 or 2. For case (b), m = 1. For case (c), m = 5/4. For case (d), m can be ±1.

In case (a), we determine that A is perpendicular to B by taking their dot product and equating it to zero. This leads to a quadratic equation in terms of m, which we can solve to find two possible values of m. In case (b), we determine that B is parallel to C by cross-checking the ratios of their corresponding components. By equating these ratios, we obtain a linear equation in terms of m, which we can solve to find the value of m. In case (c), we determine if A, B, and C lie in the same plane by checking if their cross product is zero. This leads to a linear equation in terms of m, and solving it provides the value of m. In case (d), we find that D is perpendicular to both N and B by taking their dot products. By solving the resulting equations, we can determine the value of m.

(a) For A to be perpendicular to B, their dot product should be zero: A · B = (2a1 - ma2 - a3) · (ma1 + a2 ? 2a3) = 0

Expanding the dot product and simplifying, we obtain the quadratic equation:

2m - 2m² + 4 = 0

Solving this quadratic equation yields two possible values for m: m = 1 and m = 2.

(b) To determine if B is parallel to C, we compare their corresponding components: ma1 + a2 ? 2a3 = k(a1 + ma2 + 2a3), where k is a constant. By equating the ratios of corresponding components, we get:

m = k

1 = mk

-2 = 2k

From the first two equations, we find m = 1, and substituting this into the third equation, we see that k = -1.

(c) To check if A, B, and C lie in the same plane, we need to determine if their cross product is zero:

(A × B) · C = 0

Expanding and simplifying the cross product, we obtain:

(2a2 + 4a3 + ma1) · (a1 + ma2 + 2a3) = 0

Simplifying further and rearranging terms, we get the linear equation:

4m - 5 = 0

Solving this equation yields m = 5/4.

(d) For D to be perpendicular to both N and B, their dot products should be zero:

D · N = (m²a3 + ma2 + a3) · (N1a1 + N2a2 + N3a3) = 0

D · B = (m²a3 + ma2 + a3) · (ma1 + a2 - 2a3) = 0

Expanding the dot products and simplifying, we obtain two linear equations: m² + 1 - 3m = 0

m² - 1 = 0

Solving these equations, we find m = ±1.

In summary, for case (a), m can be either 1 or 2. For case (b), m = 1. For case (c), m = 5/4. For case (d), m can be ±1.

(4) Determine the TAYLOR'S EXPANSION of the following function: 6 (z +1)(2+3) on the Annulus 1 < |-|<3. HINT: Use the basic Taylor's Expansion 11. = (-1)"".

Answers

The Taylor's Expansion of the function 6(z+1)(2+3) on the annulus 1<|z|<3 is:

6(z+1)(2+3) = 90 + 84(z-1) + O((z-1)^2)

To find the Taylor's Expansion of the given function, we can use the basic formula for Taylor's Expansion:

f(z) = f(a) + f'(a)(z-a) + (1/2!)f''(a)(z-a)^2 + (1/3!)f'''(a)(z-a)^3 + ...

Here, a = 1 since the annulus is centered at 0 and has an inner radius of 1. We can calculate the derivatives of the function as follows:

f(z) = 6(z+1)(2+3)

f'(z) = 30(z+1)

f''(z) = 30

f'''(z) = 0

f''''(z) = 0

...

Evaluating these derivatives at a=1, we get:

f(1) = 90

f'(1) = 30

f''(1) = 30

f'''(1) = 0

f''''(1) = 0

...

Plugging these values into the formula for Taylor's Expansion and simplifying, we get:

f(z) = 90 + 30(z-1) + (1/2!)(30)(z-1)^2 + O((z-1)^3)

= 90 + 30(z-1) + 15(z-1)^2 + O((z-1)^3)

Since the annulus is 1<|z|<3, we need to make sure that the remainder term in the expansion is of order (z-1)^2 or higher. We can see that the remainder term above satisfies this condition, so we can write the final answer as:

f(z) = 90 + 84(z-1) + O((z-1)^2)

an investment pays simple interest, and triples in 12 years. what is the annual interest rate?answer = _________ percent

Answers

An investment pays simple interest, and triples in 12 years. The annual interest rate for this investment is 16.67%.  

An investment that triples in 12 years with simple interest can be represented using the formula: Final Amount = Principal Amount + (Principal Amount * Annual Interest Rate * Time) Since the investment triples, the Final Amount is 3 times the Principal Amount. We can rewrite the formula as: 3 * Principal Amount = Principal Amount + (Principal Amount * Annual Interest Rate * 12 years) Now, we can solve for the Annual Interest Rate: 2 * Principal Amount = Principal Amount * Annual Interest Rate * 12 years 2 = Annual Interest Rate * 12 Annual Interest Rate = 2 / 12 Annual Interest Rate = 1/6, which is approximately 0.1667, or 16.67%.

If a lead puck has a diameter of 7.5 cm and height of 2.3 cm and is floating in the mercury then the bottom of the lead puck is 1.9 cm below the mercury surface.

In order to solve this problem, we will make use of Archimedes’ principle. Archimedes’ principle states that the buoyant force on an object equals the weight of the fluid displaced by the object.

Let the bottom of the lead puck is d meter below the mercury surface.

So, the volume of the mercury displaced by the lead puck is equal to the volume of the puck under the mercury:

V(mercury displaced) = V(puck) = πr²d,

where r = 0.075 m (diameter = 7.5 cm)

V(mercury displaced) = π(0.075 m)²d,

We also know that the density of mercury is 13,600 kg/m³ and the density of lead is 11,300 kg/m³.

Mass of mercury displaces = Volume × density = π(0.075 m)²d × 13600

Mass of the lead puck = π(0.075 m)²×0.023 × 11,300

At equilibrium weight of the mercury displaces will be equal to the weight of the lead puck.

π(0.075 m)²d × 13600 × g = π(0.075 m)²×0.023 × 11,300 × g

d = (0.023 × 11,300)/13600

d = 0.019 m

d = 1.9 cm

Therefore, the bottom of the lead puck is 1.9 cm below the surface of the mercury.

Find the particular solution of the differential equation that satisfies the initial condition(s). f?''(x) = sin(x), f?'(0) = 2, f(0) = 3f(x)=

Answers

The particular solution of the differential equation f''(x) = sin(x) that satisfies the initial conditions f'(0) = 2, f(0) = 3 is : f(x) = -sin(x) + 3x + 3

To find the particular solution of the given differential equation, we first integrate both sides with respect to x:

f'(x) = ∫sin(x) dx = -cos(x) + C1

where C1 is the constant of integration.

Next, we integrate f'(x) again:

f(x) = ∫(-cos(x) + C1) dx = -sin(x) + C1x + C2

where C2 is the constant of integration.

To find the values of C1 and C2, we use the initial conditions:

f'(0) = -cos(0) + C1 = 2

C1 = 2 + cos(0)   (Since, cos (0) = 1)

C1 = 2+1 = 3

f(0) = -sin(0) + C1(0) + C2

C2 = 0 + 0 + 3  (Since,sin(0) = 0 )

C2 = 3

Therefore, the particular solution of the differential equation that satisfies the initial conditions is:

f(x) = -sin(x) + 3x + 3

Answers

To model the relationship between the elapsed time, ttt, in years, since Alina began studying the population, and the total number of bears, n(t)n(t)n, left parenthesis, t, right parenthesis, we can use the following function:

n(t) = kt + b

where kk is a constant that represents the initial rate of population growth, and bb is a constant that represents the current population size.

To determine the values of kk and bb, we can use the following information:

The initial population size was 100,000 bears, so bb = 100,000.Alina began studying the population 10 years ago, so t = 10.

Substituting these values into the function, we get:

n(t) = 10(t + 10) + 100,000

n(t) = 100,000 + 100t

n(t) = 100,000 + 10t

Therefore, the relationship between the elapsed time, ttt, in years, and the total number of bears, n(t)n(t)n, left parenthesis, t, right parenthesis, can be modeled by the following function:

n(t) = 100,000 + 10t

Consider the following mechanism:step1: A+BC\rightarrowABCstep2: BC+ABC\rightarrowA+B2+C2overall: 2BC\rightarrowB2+C2Which species is an intermediate?Which species is a catalyst?

Answers

ABC is the intermediate, and A is the catalyst in this reaction mechanism.

In the given mechanism, an intermediate is a species that is formed in one step but is then consumed in a subsequent step.

In this mechanism, the species ABC is an intermediate because it is formed in step 1 but is then consumed in step 2.

This means that it does not appear in the overall equation for the reaction, as it is not a reactant or product.
On the other hand, a catalyst is a species that speeds up the rate of a reaction without being consumed itself.

In this mechanism, there is no catalyst because none of the species involved speeds up the reaction without being consumed itself.

All the species are either reactants or products or intermediates.
Overall,

The mechanism shows a reaction between A, B, and C, which involves two steps. In the first step, A reacts with BC to form the intermediate ABC.

In the second step, BC reacts with ABC to form A, B2, and C2.

The overall equation for the reaction shows that two moles of BC react to form one mole each of B2 and C2.

This mechanism represents a complex reaction that occurs in multiple steps, and it is important to understand the role of intermediates in these steps to better understand the reaction as a whole.

In this mechanism, ABC is an intermediate because it is formed in the first step and consumed in the second step. BC is a catalyst because it is not consumed or formed in the overall reaction but it facilitates the reaction by participating in both steps. ABC is the intermediate and A is the catalyst in this reaction mechanism.


Let's analyze the given reaction mechanism to identify the intermediate and the catalyst.

Step 1: A + BC → ABC
Step 2: BC + ABC → A + B2 + C2
Overall: 2BC → B2 + C2

1. Identify the intermediate:
An intermediate is a species that is produced in one step and consumed in another. In this mechanism, ABC is formed in step 1 and consumed in step 2. Therefore, ABC is the intermediate.

2. Identify the catalyst:
A catalyst is a species that is consumed in one step and regenerated in another step without being consumed in the overall reaction. In this mechanism, A is consumed in step 1 and regenerated in step 2. Since A does not appear in the overall reaction, it is the catalyst.

In conclusion, ABC is the intermediate and A is the catalyst in this reaction mechanism.

Producing large quantities of a gene product, such as insulin, and to learn how a cloned gene codes for a particular protein are examples of why biologists clone

Answers

Biologists clone genes for various reasons, and two examples are; Producing large quantities of a gene product, and Understanding gene function and protein synthesis.

How to Identify Biological Cloning?

Production of large amounts of gene products. Cloning duplicates genes to produce large amounts of a particular gene product. This is especially useful for genes that code for proteins with important functions such as insulin. By cloning the gene responsible for insulin production, scientists can introduce it into host organisms such as bacteria or yeast to produce large amounts of insulin for medical purposes.

Understand gene function and protein synthesis. Gene cloning offers researchers the opportunity to study how a particular gene encodes a particular protein. By isolating and replicating a gene of interest, scientists can study its structure, function, and the proteins it encodes. This enables a deeper understanding of the role of specific proteins in gene expression, protein synthesis and cellular processes. Cloning genes also allows researchers to manipulate and modify genes to study the effects of genetic changes on protein structure and function.

Construct a 98% confidence interval for the mean starting salary of recent college graduates with a GPA of 3.15. Construct a 98% predic- tion interval for the starting salary of a randomly selected recent college graduate with a GPA of 3.15.

Answers

We can be 98% confident that the true mean starting salary of recent college graduates with a GPA of 3.15 lies between $36,540 and $55,740.

We can be 98% confident that the starting salary of a randomly selected recent college graduate with a GPA of 3.15 lies between -$32,080 and $124,360.

First, we need to calculate the sample mean, which is the average starting salary of the seven college graduates given:

sample mean = (48 + 53 + 50 + 37 + 65 + 32 + 37) / 7 = 46.14 thousand dollars

Next, we need to calculate the standard error. The sample standard deviation is calculated as follows:

s = √[((48-46.14)² + (53-46.14)² + (50-46.14)² + (37-46.14)² + (65-46.14)² + (32-46.14)² + (37-46.14)²) / 6] = 11.36 thousand dollars

The square root of the sample size is calculated as:

√(7) = 2.65

So, the standard error is:

standard error = 11.36 / 2.65 = 4.28 thousand dollars

Finally, we need to find the t-value for a 98% confidence level and 6 degrees of freedom (sample size - 1). We can use a t-table or a calculator to find this value, which is approximately 2.447.

Now we can plug in all the values into the formula to get the confidence interval:

Confidence interval = 46.14 ± 2.447 * 4.28 = (36.54, 55.74)

The t-value and standard error are calculated in the same way as in the confidence interval, but we also need to calculate the sample standard deviation, which is the square root of the variance:

variance = [(48-46.14)² + (53-46.14)² + (50-46.14)² + (37-46.14)² + (65-46.14)² + (32-46.14)² + (37-46.14)²] / 6

= 1315.43 thousand dollars squared

sample standard deviation = √(variance) = 36.26 thousand dollars

Now we can plug in all the values into the formula to get the prediction interval:

Prediction interval = 46.14 ± 2.447 * 4.28 ± 2.447 * 36.26 = (-32.08, 124.36)

Misclassifying an actual Class 0 observation as a Class 1 observation is known as a false positive.

In binary classification, Class 0 typically represents the negative class or the absence of a certain condition, while Class 1 represents the positive class or the presence of the condition. A false positive occurs when the classifier identifies an observation as belonging to the positive class when it actually belongs to the negative class.

This can be problematic in certain applications, such as medical diagnosis, where a false positive can lead to unnecessary treatment or procedures. False positives can also have implications in areas such as fraud detection, spam filtering, and quality control. Therefore, minimizing the occurrence of false positives is an important consideration in developing and evaluating classification models.

6). positive integer n is the product of the odd numbers from 99 to 199, inclusive. if n is divisible by 5k , what is the greatest possible value of k?

Answers

The greatest possible value of k such that n is divisible by 5k is 39.

What is odd number?

Any number that cannot be divided by two is considered an odd number. For instance, 25 is strange because it cannot be split by 2. A integer is considered to be divisible by two if its last digit is any of the following: 0, 2, 4, 6, or 8.

To find the greatest possible value of k such that n is divisible by 5k, we need to determine the highest power of 5 that divides n.

The product of the odd numbers from 99 to 199, inclusive, can be expressed as:

n = 99 * 101 * 103 * ... * 197 * 199

To find the power of 5 that divides n, we need to determine the number of factors of 5 in the product.

A factor of 5 is introduced for every multiple of 5 in the product. We need to count the multiples of 5 in the range from 99 to 199.

The largest multiple of 5 in that range is 195, which is 39 * 5.

Therefore, there are 39 multiples of 5 in the product.

To find the highest power of 5 that divides n, we divide 39 by k and find the largest possible integer value for k.

The largest possible value of k is the largest factor of 39.

The factors of 39 are 1, 3, 13, and 39.

Since we are looking for the greatest possible value of k, the answer is 39.

Therefore, the greatest possible value of k such that n is divisible by 5k is 39.
