Question

What is the predicted price of a set that has 2,520 pieces according to the regression equation ý= 0.08x + 1.20?

A. 202.80
B. 2,017.20
C. 3,024.08
D. 31,485

Answer 1

To find the predicted price of a set with 2,520 pieces based on the provided regression equation, substitute the value into the equation to get ý = 0.08(2,520) + 1.20, which equals $202.80.

Step-by-step explanation:

The student is asking about a linear regression equation prediction. Given the regression equation ý = 0.08x + 1.20, we can calculate the predicted price of a set with 2,520 pieces. We substitute the value of x (2,520 pieces) into the equation as follows:

ý = 0.08(2,520) + 1.20

ý = 201.60 + 1.20

ý = 202.80

Therefore, the predicted price of the set with 2,520 pieces is $202.80, which corresponds to option A.
