A bookstore sells books for $2, $3, $5, and $10. Let random variable X = "amount of
money for one book."
Look at the relative-frequency table below representing the amount of money spent on
one item and the relative frequencies with which customers purchase them
If the expected amount of money spent by a customer is $3.23 what is the standard deviation?
The value of the standard deviation is σ = 2.20. Using probability distribution, the required standard deviation is calculated.
How to calculate the standard deviation?The formula for the standard deviation of the given probability distribution is
σ = √∑([tex]x_i^2[/tex] × [tex]P(X_i)[/tex]) - μₓ²
Where the mean μₓ = ∑[[tex]x_i[/tex] × [tex]P(X_i)[/tex]]
Calculation:It is given that,
x: $2, $3, $5, $10
P(X=x): 0.55, 0.26, 0.11, 0.08
Step 1: Calculating the mean:
we have μₓ = ∑[[tex]x_i[/tex] × [tex]P(X_i)[/tex]]
⇒ μₓ = 2 × 0.55 + 3 × 0.26 + 5 × 0.11 + 10 × 0.08
∴ μₓ = 3.23
Step 2: Calculating the standard deviation:
x: 2, 3, 5, 10
x²: 4, 9, 25, 100
P(X=x): 0.55, 0.26, 0.11, 0.08
([tex]x_i^2[/tex]) × [tex]P(X_i)[/tex]: 4 × 0.55 = 2.2; 9 × 0.26 = 2.34; 25 × 0.11 = 2.75; 100 × 0.08 =8
∑[([tex]x_i^2[/tex]) × [tex]P(X_i)[/tex]]: 2.2 + 2.34 + 2.75 + 8 = 15.29
Therefore,
The standard deviation, σ = √∑([tex]x_i^2[/tex] × [tex]P(X_i)[/tex]) - μₓ²
⇒ σ = [tex]\sqrt{15.29-(3.23)^2}[/tex]
= [tex]\sqrt{15.29-10.43}[/tex]
∴ σ = 2.20

State the transformations being applied to each quadratic function.
a) y = -1/2(x+2)^2+4
b) y= -(x-1)^2-2
c) y=(4x)^2
d) y= 4x^2
The function transformations are:
The function (a) y = -1/2(x + 2)^2 + 4 is translated to the left by 2 units, reflected across the x-axis, compressed vertically by a factor of 1/2 and translated up by 4 unitsThe function (b) y = -(x - 1)^2 - 2 is translated right by 1 unit, reflected across the x-axis, and translated down by 2 unitsThe function (c) y = (4x)^2 is stretched horizontally by a factor of 1/4The function (d) y = 4x^2 is stretched vertically by a factor of 4What are transformations?Transformations involve translating, reflecting, rotating and dilating a function across the coordinate plane
How to determine the transformations?The parent function of a quadratic function is represented as:
y = x^2
When the function is stretched horizontally by a factor of k, where k is between 0 and 1, we have:
y = (x/k)^2
Assume k = 1/4. we have:
y = (4x)^2
This means that the function (c) y = (4x)^2 is stretched horizontally by a factor of 1/4
When the function is stretched vertically by a factor of k, where k is greater than 1, we have:
y = k(x)^2
Assume k = 4. we have:
y = 4x^2
This means that the function (d) y = 4x^2 is stretched vertically by a factor of 4
Translating the function left is represented as:
y = (x + k)^2
Assume k = 2. we have:
y = (x + 2)^2
Reflecting the function across the x-axis is represented as
y = -(x + 2)^2
When the function is compressed vertically by a factor of k, where k is between 0 and 1, we have:
y = -k(x + 2)^2
Assume k = 1/2. we have:
y = -1/2(x + 2)^2
Translating the function up is represented as:
y = -1/2(x + 2)^2 + k
Assume k = 4. we have:
y = -1/2(x + 2)^2 + 4
Hence, the function (a) y = -1/2(x + 2)^2 + 4 is translated to the left by 2 units, reflected across the x-axis, compressed vertically by a factor of 1/2 and translated up by 4 units
Translating the function right is represented as:
y = (x - k)^2
Assume k = 1. we have:
y = (x - 1)^2
Reflecting the function across the x-axis is represented as
y = -(x - 1)^2
Translating the function down is represented as:
y = -(x - 1)^2 - k
Assume k = 2. we have:
y = -(x - 1)^2 - 2
Hence, the function (b) y = -(x - 1)^2 - 2 is translated right by 1 unit, reflected across the x-axis, and translated down by 2 units

A 12 foot ladder is leaning against a building. If the bottom of the ladder is sliding along the pavement directly away from the building at 2 feet/second, how fast is the top of the ladder moving down when the foot of the ladder is 3 feet from the wall
Using Pythagoras theorem, the top of the ladder moving down when the foot of the ladder is 3 feet from the wall is of -0.518 feet/sec.
Let distance from the wall to the foot of the ladder is 'x' feet and the height of the top of the ladder is 'y' feet.
Pythagoras theorem, [tex]x^{2} + y^{2} = (12)^{2}[/tex] --->(1)
Given,[tex]\frac{dx}{dt}= 2feet/second[/tex] at x=3
Put x=3 in Pythagoras theorem equation (1)
[tex](3)^{2} + y^{2} = 144[/tex]
[tex]y^{2} = 144 - 9[/tex]
[tex]y^{2}[/tex] = 135
y = 11.61
Derive equation (1) w.r.t to 't'
[tex]2x\frac{dx}{dt} + 2y\frac{dy}{dt} = 0[/tex] ---->(2)
substitute the value of 'x', 'dx/dt' and 'y' in equation (2), we get the fast of the top of the ladder moving down when the foot of the ladder is 3 feet from the wall
[tex]2(3)(2) + 2 (11.61)\frac{dy}{dt} = 0[/tex]
12 + 23.22 [tex]\frac{dy}{dt}[/tex] = 0
[tex]\frac{dy}{dt}= \frac{-12}{23.22}[/tex]
[tex]\frac{dy}{dt} = -0.518[/tex]

uan recently hired a roofer to do some necessary work. On the final bill, Juan was charged a total of $1131.5. $450 was listed for parts and the rest for labor. If the hourly rate for labor was $47, how many hours of labor was needed to complete the job?
Based on the total cost that Juan incurred to hire the roofer including the charge for parts and labor, the number of hours that was needed to complete the job was 14.50 hours.
How many hours did the roofer use?The first thing to do is to find out the amount that went to labor:
= Final bill - cost of materials
= 1,131.5 - 450
= $681.50
Now that you have the cost of labor, you can find out the number of labor hours that were used based on the hourly rate:
= Cost of labor / Hourly rate
Solving gives:
= 681.50 / 47
= 14.5 hours

Solve for X in the diagram below
Step-by-step explanation:
the sum of all angles around a single point on one side of a line must be 180°.
because that line can be seen as the extension of the diameter of a circle, and the point would be the center of that circle. so, one side of the line represents a half-circle, which stands for 180°.
so we have
180 = 40 + 40 + (2x + 30) = 80 + 2x + 30 = 110 + 2x
70 = 2x

3) A normal distribution has a mean of 75 and a standard deviation of 15. Determine the z-score for the data value of 85.
Step-by-step explanation:
z = (specific score - mean) / standard deviation
in our case
z = (85 - 75)/15 = 10/15 = 2/3 = 0.666666... ≈ 0.67
as z-tables usually round the z-score to hundredths.
The z-score for the data value of 85 is 0.67.
How to Calculate Z-Score?A Z-score is a metric that quantifies how closely a value relates to the mean of a set of values. Standard deviations from the mean are used to measure Z-score. A Z-score of zero means the data point's score is the same as the mean score. A value that is one standard deviation from the mean would have a Z-score of 1.0. Z-scores can be either positive or negative, with a positive number signifying a score above the mean and a negative value signifying a score below the mean.
To find the z-score, you simply need to apply the following formula:
z = (x - μ) / σ
μ=75
σ=15
x=85
z =85-75/15
z=10/15
=2/3
=0,66666....=0.67
Therefore, the z-score for the data value of 85 is 0.67.

The likelihood that a patient with a heart attack dies of the attack is 0.04 (i.e., 4 of 100 die of the attack). Suppose we have 50 patients who suffer a heart attack. What is the probability that all will survive
The probability solved by binomial distribution that all will survive is 0.8154.
What is Binomial distribution?When each trial has the same probability of achieving a given value, the number of trials or observations is summarized using the binomial distribution. The likelihood of observing a specific number of successful outcomes in a specific number of trials is determined by the binomial distribution.
Computation of probability of all survived people from heart attack;
A heart attack patient has a 0.04 percent chance of dying from the attack (i.e., 4 of 100 die of the attack).
What is the likelihood that each of the five patients who experience a heart attack will survive?
We'll refer to a victory in this scenario as a heart attack (p = 0.04). In other words, we are interested in the likelihood that none of our n=5 patients will die (0 successes).
Each attack has a chance of being fatal or not, with a probability of 4 percent for all patients, and each patient's result is independent.
Assume for the purposes of this example that the five individuals being examined are unrelated, of the same age, and free of any concomitant disorders.
By binomial distribution,
[tex]\begin{gathered}P(0 \text { successes })=\frac{5 !}{0 !(5-0) !} 0.04^{0}(1-0.04)^{5-0} \\P(0 \text { successes })=\frac{5 !}{5 !}(1)(0.96)^{5}=(1)(1)(0.8154)=0.8154\end{gathered}[/tex]
Therefore, with a 4 % chance that anyone will die, there is an 81.54% chance that every patient will survive the onslaught. The outcomes in this example could be 0, 1, 2, 3, 4 or 5 successes (fatalities).

What is Heron's Formula?
Heron's formula was first given by Heron of Alexandria. It is used to calculate the area of various triangles such as equilateral, isosceles, and scalene triangles or quadrilaterals. When we know the sides of a triangle, we can use Heron's formula to find its area. Using Heron's formula, we find the area of a triangle by taking its semi-perimeter and side lengths.Heron's formula is used to calculate the area of triangles given the lengths of all their sides, as well as the area of quadrilaterals. It's also known as Hero's formula. This formula for calculating the area does not rely on the angles of a triangle. It is solely determined by the lengths of all triangle sides. It contains the term "s," which stands for semi-perimeter, which is obtained by halving a triangle's perimeter. Similarly, the concept of determining the area is extended to determine the area of quadrilaterals.To learn more about Hero's formula visit:
