The total cost y in dollars for renting a scooter and driving it x miles is y- 0.30x + 25 a. Explain whether the relationship between the cost y of renting the scooter for a day and the distance x that the scooter is driven that day is deterministic or contains an element of randomness. b.

Answer #1

A. The regression equation is

y=0.3x+25

Since slope is 0.3 ( positive)

There is a positive relation between y and x

B. The regression. Equation is

y= 0.3x+25

When x=34

y=0.3(34) +25

y=35.2
