Question

I predict i have 20 cents in my piggy bank. if i actually have 25 cents. what the percent error?

Answer 1

The percent error is 20%

Explanation:

The formula for percent error is:

PE = |Predicted Value - Real Value| / Real Value

PE = |20 - 25| / 25 × 100

PE = |-5| / 25 × 100

PE = 5/25 × 100

PE = 20%

Answer 2

Your percent error is 20% with the prediction of 20 cents in your piggy bank when the actual amount is 25 cents.

Explanation:

The formula for percent error is (|predicted value - actual value|)/(actual value) * 100.

% Error = |(20 - 25)|/(25) * 100
= (|-5|)/25 * 100
= 5/25 * 100
= 20%
