Question

diego is collecting pennies and estimated that he has 120 pennies. he counted them and has 80 pennies. what is diego's percentage error? write yuor answer in the box.

Answer 1

50%

Explanation:

The percent error is equal to the absolute value, difference of the measured value or your experimental value minus the actual value divided by the actual value times 100%;

Here we have;

Measured Valued = 120 pennies

Actual Value = 80 pennies

% error =
`(|Measured - Actual|)/(Actual) * 100`

% error =
`(|120 - 80|)/(80) * 100`

% error =
`(|40|)/(80) * 100`

% error =
`(40)/(80) * 100`

% error = 50%

So, 50% is the percent error for Diego
