Question

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.

Explanation:

Step1: Find the absolute error

The absolute error is the absolute value of the difference between the actual value and the estimated value. So, \( |305 - 280| = 25 \) mm.

Step2: Use the percent error formula

The formula for percent error is \( \text{Percent Error} = \frac{|\text{Estimated Value} - \text{Actual Value}|}{\text{Actual Value}} \times 100\% \). Substituting the values, we get \( \frac{25}{305} \times 100\% \).

Step3: Calculate the value

\( \frac{25}{305} \times 100\% \approx 8.1967\% \), which rounds to 8% when rounded to the nearest whole percent.

Answer:

8%
