Answer:

D. 324 miles

Step-by-step explanation:

The scale is 2 inches: 45 miles.

Let's just say that is 2/45 because the units won't change in this problem.

2 inches = 45 miles

14.4 inches = ???

proportion time ._.

2/45 = 14.4/x

14.4 * 45 = 648

Answer:

<u>23 consumer.</u>

Step-by-step explanation:

Given:

Number Of Responses for Thirsty = 49

Number Of Responses for Clean = 24

Number Of Responses for Strong Ones = 15

Number Of Responses for PowerWash = 12

So,

The total number of Responses = 49 + 24 + 15 + 12 = 100

So, the probability to prefer PowerWash = 12/100 = 0.12

For a group of 195 consumers:

prediction to prefer PowerWash paper towels = 0.12 * 195 = 23.4

So,

The number of consumers prefer PowerWash paper towels = <u>23 consumer</u>

It is assumed that the time customers spend in a record store is uniformly distributed between 3 and 12 minutes. Based on this i

Answer:

0% probability that a customer will be exactly 7.50 minutes in the record store.

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.

The probability of finding a value of at lower than x is:

$P(X < x) = \frac{x - a}{b - a}$

The probability of finding a value between c and d is:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

The probability of finding a value above x is:

$P(X > x) = \frac{b - x}{b - a}$

The uniform distribution is a continuous distribution, which means that the probability of an exact outcome is zero.

Uniformly distributed between 3 and 12 minutes.

This means that $a = 3, b = 12$

What is the probability that a customer will be exactly 7.50 minutes in the record store?

Continuous distribution, so:

0% probability that a customer will be exactly 7.50 minutes in the record store.
