Complete question :
Marquis wrote the linear regression equation y = 1.245 x minus 3.684 to predict the cost, y, of x songs purchased. Marquis spent $40 on songs. Which is the best estimate of the number of songs that Marquis purchased?
Answer:
29
Step-by-step explanation:
Given that :
Regression equation equals :
y = 1.245x - 3.684
y = predicted cost ; x = number of songs purchased
If y = $40 ; amount spent
Put y = 40 in the regression equation and solve for x
40 = 1.245x - 3.684
40 - 3.684 = 1.245x
36.316 = 1.245x
x = 36.316 / 1.245
x = 29.169477
Best estimate = 29
Answer:
the best estimate of the number of songs that Marquis purchased is 35
