may estimates her dresser drawer is 280 mm deep, but its actually 305 mm deep. what is the percent error in mays estimate? round to the nearest whole percent.

Answer

Explanation:

Step1: Calculate the error

Error = |Estimated value - Actual value| = |280 - 305| = 25

Step2: Calculate the percent - error formula

Percent error=$\frac{\text{Error}}{\text{Actual value}}\times100%=\frac{25}{305}\times100%$

Step3: Calculate the result

$\frac{25}{305}\times100%\approx8.2%$

Step4: Round to the nearest whole percent

Rounding 8.2% to the nearest whole percent gives 8%

Answer:

8%
