Question

chris estimates his dirt bike to weigh 210 pounds, but its actually 245 pounds. what is the percent error in chris 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, we calculate \(|245 - 210|\).
\(|245 - 210| = 35\)

Step2: Calculate the percent error

The formula for percent error is \(\frac{\text{Absolute Error}}{\text{Actual Value}} \times 100\%\). We substitute the absolute error (35) and the actual value (245) into the formula.
\(\frac{35}{245} \times 100\% \approx 0.1429 \times 100\% = 14.29\%\)

Step3: Round to the nearest whole percent

Rounding 14.29% to the nearest whole percent gives us 14%.

Answer:

14
