Question

You estimate that a piglet weighs 9 pounds. The actual weight of the piglet is 11 pounds. Find the percent error. Round your answer to the nearest hundredth of a percent. PLEASE ANSWER

Answer 1

The percent error is calculated like by subtracting the actual amount from the estimated amount, dividing by the actual amount, taking the absolute value of this number, and multiplying by 100:


`|(estimated -actual)/(actual) |*100`

Plug in the values:


`|(9-11)/(11) |*100= \\ \\ | (-2)/(11) |*100 $\approx$ \\ \\ \(\lvert -0.1818\rvert\) *100= \\ \\ 0.1818*100=18.18\%`

The percent error should be ~18.18%.
