Answer: I am going tot give you an example for this because I don’t like giving straight up answers ok?

Step-by-step explanation:

Lets use this conversion factor:

4 inches = 1 year

Let's find the year at 5 feet (60 inches) using the conversion factor. Set up a proportion.

4 / 60 = 1 / x

Cross multiply.

4x = 60

x = 15

At 15 years, the height is 60 inches.

We can use these as points.

x = time in years

y = height in inches

Point 1 = (1, 4)

Point 2 = (15, 60)

By looking at the points, we know that as the x values increase, so does the y values. Now the relation between the x and y values of each point is that y is 4 times as that of x. Therefore, we can establish an equation.

y = 4x

This will be the model to use to find the height in 30 years.

Answer:

Step-by-step explanation:

-7x + 12 + (-8x + 48) = 180

-15x + 60 = 180

-15x = 120

x = -8

m<BDC= -7(-8)+ 12 = 56 + 12 = 68

m<CBA = -8(-8)+48 = 64+48 = 112

Which of the following question is not considered a statistical question?
vekshin1

Answer:

B. How many total customers were at the story today?

Step-by-step explanation:

Option 'B' is not a statistical question because there is not more than one answer.

There is only one answer to this question.

Option 'A,' 'C,' and 'D' are statistical questions because there is more than one answer.

<em>What amounts did each person at the store spend on their purchase?</em>

This question has more than one answer.

<em>How long did each customer spend shopping at the store?</em>

<em>What are the heights of each customer who entered the store?</em>

These questions have more than one answer as well.

Statistical questions are questions that have more than one answer. This means you can collect data.

I, therefore, believe that option 'B' is not a statistical question.
