Asked by Red

Enid jogs on a treadmill for exercise. Each time she finishes jogging, the treadmill will report the number of calories she burned. Enid claims that the distance she jogs and the number of calories she burns are in a proportional relationship. Data from her last four jogs are shown.



Which of the following methods can Enid use to test her claim? Choose the two correct answers.

Responses

She could calculate the ratio change in calories burned to change in miles jogged for two data point and compare the results to the same ratio with two other data points.


She could plot the data on a coordinate plane and see if a straight line starting at (0, 0) passes through all the data points.


She could put the data in a table and check to see that the difference between the number of calories burned changes by the same amount for each row.


She could calculate the ratio between the number of calories burned for each pair of jogs and see if the ratio is always the same.

She could calculate the correlation coefficient between the distance jogged and the number of calories burned.
