Answer:
OptionC
Step-by-step explanation:
Given that the correlation coefficient (r) between the number of miles driven x and the number of gallons of gasoline used y is 0.925
Coefficient of determination = square of r
= 0.8556
=85.6%
Hence the percent of the variation in the number of gallons of gasoline can be explained by differences in the number of miles driven is 85.6%
Option C
The correct answer is 85.6 hope that helps
