Question

The costs of shipping packages of varying sizes that weigh up to 40 pounds are shown below. Ground Shipping 30 Cost (in dollars) 20 10 20 30 Weight (in pounds) Maxine made the following statements about the data shown. I The more a package weighs, the greater the cost to ship it. IT The less a package weighs, the cheaper the cost to ship it. III The data shows a positive linear correlation. IV It would cost between $10 and $15 to ship an 8-pound package. Which of the following statements that Maxine made about the data are true?

Answer 1

we have the following:

Let's analyze each sentence to be able to answer the correct answer.

• The more a package weighs, the greater the cost to ship it

This is correct, we can see in the graph that the cost increases with the increase in weight

• The less a package weighs, the cheaper the cost to ship it

This is correct, we can see in the graph that the cost decreases with the decrease in weight

• The data shows a positive linear correlation

If it is a positive linear correlation since they are directly proportional in a positive way (if one increases, the other also increases)

• It would cost between $10 and $15 to ship an 8-pound package

If we look at the graph we can see that these values are correct and consistent, therefore it is correct

Which means that the correct answer is D. since all the statements are correct
