Quizplus · Accepted Answer

To find the mean, add up all the miles per gallon and divide by the number of trucks:

(20+8+18+13+16+9+21)/7 = 105/7 = 15

Rounded to the nearest whole number, the mean miles per gallon for the fleet is 15 mpg. To find the mean, we add up all the numbers and divide by the total number of trucks:
(20+8+18+13+16+9+21)/7 = 105/7 ≈ 15 mpg
Rounding to the nearest whole number, we get 15 mpg, which is answer choice C.
