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

.bjbjk.b,j.l.

step-by-step explanation:

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
