There are 4 variables but 3 are numerical or quantitative

Step-by-step explanation:

See Attachment for proper format of question.

Required

The individuals in this data set are:

This data set contains:

Solving (a):

From the attachment, we have the following columns:

Cars Sold; Retail Price; Miles Per Gallon; Seats; Navigation

Solving (b):

In (a) above, we established the individual to be cars sold.

The other 4 elements are what the data set contains i.e. variables.

From the attachment, we have that

retail price, miles per gallon and seats are numerical data while navigation isn't.

So, we can conclude that.

Ben drinks water everyday. He drinks 3 1/2 liters of water every 1/4 of an hour. Ben drinks water at a constant rate. How many liters of water can Ben drink in 3 hours?

Answers

Ben drinks 3 1/2 liters of tea every 40 minutes.

This means that he would drink 1 3/4 of tea every 20 minutes (divide both sides by 2).

Now, let's multiply each side by 3.

1.75 * 3 = 5.25 (aka 5 1/4)

20 * 3 = 60 minutes (an hour)

He drinks 5 1/4 liters of tea in one hour.

Answer:

42 liters

Step-by-step explanation:

3.5x4=14 in 1 hour

Find the limit
(calculus)

Answers

Answer:

Step-by-step explanation:

Step 1: Define

[tex]\lim_{x \to \infty} e^{x-x^2}[/tex]

Step 2: Substitute in infinity

[tex]\lim_{x \to \infty} e^{\infty-\infty^2}[/tex]

We know that the second exponent is always going to be bigger than the 1st exponent, so we would get a negative exponent.

[tex]\lim_{x \to \infty} e^{-\infty}[/tex]

We can simplify a negative exponent into a fraction.

[tex]\lim_{x \to \infty} \frac{1}{e^{\infty}}[/tex]

We know that if we keep plugging in larger numbers for x, the denominator is going to be infinitely big. And bigger the number we are dividing by, the smaller the entire fraction is going to be.

Therefore, we would be approaching 0.

Answer: x=3

Step-by-step explanation: subtract 11 from 20 and you'll get 9. Nine divided by 3= 3. Therefore, x=3

Answer:

x = 3

Step-by-step explanation:

3x + 11 = 20

Subtract 11 from both sides.

3x + 11 = 20

3x -11 = -11

3x = 9

Divide both sides by 3

3x/3 = 9/3

Simplify the equation

x = 3

Check; Plug 3 into the equation

3(3) + 11 = 20

9 + 11 = 20

A pitchers earned-run average E varies directly as the number R of earned runs allowed and inversely as the number of I innings pitched. A certain pitcher had an earned-run average of 2.92, giving up 85 earned runs in 262 innings. How many earned runs would the pitcher have given up having pitched 311 innings with the same average?

Answers

9514 1404 393

Answer:

101 runs

Step-by-step explanation:

The given relation is ...

E = kR/I

The value of k can be found from the given numbers.

2.92 = k(85/262)

k = 2.92(262/85) = 9

Solving the above equation for R, we get ...

R = E·I/9 = (2.92)(311)/9 = 100.9 ≈ 101

The pitcher would have given up 101 earned runs in 311 innings.

In the population served by the New York Blood Center, 45% have blood type O. Consider the next 15 blood donations to the center from unrelated individuals. (a) What is the probability that exactly three have blood type O? (Enter your answer rounded to four decimal places.)

Answers

Answer:

0.03177

Step-by-step explanation:

Prob (Bld grp) ~ Bin (N, P)

N = 15, P = Prob of success ie 'O' blood type = 0.45

P (BG = 0) for 3 people = (N c X) P^X . (1-P)^N-X

As X = 3. So Prob = (15 c 3) (0.45)^3 (0.55)^12

= 455 (0.091125) (0.0007662)

= 0.03177

a. The probability that exactly three have blood type O is 0.03177

Calculation of the probability:

Since

Prob (Bld grp) ~ Bin (N, P)

N = 15,

P = Prob of success ie 'O' blood type = 0.45

Now

P (BG = 0) for 3 people = (N c X) P^X . (1-P)^N-X

So,

As X = 3. So Prob = (15 c 3) (0.45)^3 (0.55)^12

= 455 (0.091125) (0.0007662)

= 0.03177

hence, The probability that exactly three have blood type O is 0.03177

explain the relationship between a strategy such as number sense and a written method such as partial products or area models for multiplying decimal numbers

Answers

There are a lot of differences between these two.

Step-by-step explanation:Firstly, strategy are all in mind and not on paper while written methods are solid proofs that are written on paper. Strategies may or may not work out with respect to the situation, while Written method will always work. They are actually written after testing their reliability. As far as you multiply decimal numbers these will go in vain and you have to use your mind to solve these

The relationship between strategy and written method in mathematics is that;

Strategies can be changed or modified whereas written methods cannot be changed or modified because they have standards upon which such methods are based.

In mathematics, strategies are defined as the different ways in which a problem can be approached. For example;

A student wants to perform addition of 19 and 46.

He could add the number straight away by doing 19 + 46 = 65or he can

take away 1 from 46 to become 45 and add that 1 to 19 to become 20 and

then sum 45 and 20 together as 20 + 45 = 65.

So we can see that the two strategies used to add 19 and 46 gave the same result.

In contrast, when dealing with written methods like partial products one cannot use any other method apart from that stated in the written method.

For example, we want to use partial products to multiply 13 x 52.

The solution would become (10 × 50) + (10 × 2) + (3 × 50) + (3 × 2) = 676.

In this method, there cannot be another way used as the standard for using partial products is written and fixed.
