Question

pleaseee help me

Match each actual value with the predicted value that results in a fifteen percent error.

Match Term Definition
Actual: 80 A) Predicted: 85
Actual: 120 B) Predicted: 102
Actual: 100 C) Predicted: 119
Actual: 140 D) Predicted: 92

Answer 1

I disagree with their numbers, a bit. Clearly 140 is supposed to go with 119, but a +15% error on 119 is 136.85, not 140. 119 is a -15% error from 140, but 140 is the actual number, not predicted, so we shouldn't be using it as the base point for calculating the error.

Answer 2

write those words in numbers .

Answer 3

Anyhow, multiply each number on the left by both 0.85 and 1.15 (-15% and +15% respectively). If either of those matches a number in the right column, that's the corresponding answer.

Answer 4

I dont know how to do that
