Question

The following scatter plot represents the relationship between a person's weight and the number of calories the person burns in one minute of jump roping. Using the line of best fit, about how many calories per minute could you expect a 125-pound person to burn while jump roping?

A) 11
B) 10
C) 13
D) 12

Answer 1

To estimate the number of calories per minute a 125-pound person could burn while jump roping, use the line of best fit and the weight increase to calories burned ratio.

Step-by-step explanation:

To estimate the number of calories per minute a 125-pound person could burn while jump roping, we can use the line of best fit on the scatter plot.

Based on the line of best fit, we can see that for every 10-pound increase in weight, the number of calories burned per minute increases by about 1. Therefore, for a 125-pound person, the expected number of calories burned per minute can be estimated by adding 1.25 calories to the intercept of the line of best fit.

As the options provided range from 10 to 13 calories, we can round the estimate to the nearest whole number, giving us an answer of 11 calories per minute.
