diego is collecting pennies and estimated that he has 120 pennies. he counted them and has 80 pennies. what is diego's percentag

Bezzdna [24]

Answer:

50%

Step-by-step 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 = $\frac{|Measured - Actual|}{Actual} * 100$

% error = $\frac{|120 - 80|}{80} * 100$

% error = $\frac{|40|}{80} * 100$

% error = $\frac{40}{80} * 100$

% error = 50%

So, 50% is the percent error for Diego
