Question

question 10 of 10 suppose the linear regression line y = 3.009x - 77.131 predicts a pizza parlors profits based on the number of pizzas sold. if x represents the number of pizzas sold, and y represents the pizza parlors profits in dollars, about how much can the pizza parlor expect in profits if it sells 275 pizzas? a. $675 b. $825 c. $750 d. $900

Explanation:

Step1: Substitute x - value

Substitute $x = 275$ into $y=3.009x - 77.131$.
$y=3.009\times275-77.131$

Step2: Calculate multiplication

$3.009\times275 = 827.475$.
$y = 827.475-77.131$

Step3: Calculate subtraction

$y=827.475 - 77.131=750.344\approx750$

Answer:

C. $750$
