Question

anjay wasnt sure about an answer on his science test. he guessed 84 degrees was the answer and the correct answer was 94 degrees. what is his percent of error? round to the nearest whole number. 12% 11% 13% 89%

Explanation:

Step1: Find the absolute error

Absolute error = |Estimated value - Actual value| = |84 - 94| = 10

Step2: Calculate the percent error

Percent error formula is $\frac{\text{Absolute Error}}{\text{Actual Value}}\times100\%$.
Substitute the values: $\frac{10}{94}\times100\%=\frac{1000}{94}\% \approx 10.64\%$
Rounding 10.64% to the nearest whole number gives 11%

Answer:

11%
