The correlation coefficient (r) between the number of miles driven x and the number of gallons of gasoline used y is 0.925 what percent of the variation in the number of gallons of gasoline can be explained by differences in the number of miles driven? 7.5% 14.4% 85.6% 92.5%

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

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)
