Question

I really need the help
Match each actual value with the predicted value that results in a thirty−five percent error.
Actual: one hundred forty A) Predicted:ninety−one
Actual: one hundred B) Predicted:seventy−eight
Actual: eighty C) Predicted: sixty−five
Actual: one hundred twenty D) Predicted: one hundred eight

Answer 1

Basically, a 35% error means that the actual value may be either 35% higher or lower than the latter.

For example, 20% of X is
\[\frac{ 20 }{ 100 } \times x = 0.2x\]
Therefore, the margin of error will be
\[x-0.2x \le x \le x + 0.2x\]

Let's say x = 200 and the 20% error still the same

Therefore, the range of errors lie between:
\[200 - 0.2(200) \le 200 \le 200 + 0.2(200) \]

I hope that helps

Answer 2

What I meant is that the predicted value will be between the margin of 35% higher or lower than the actual value.
