Question

Craig estimates his driving score to be 8.5. His actual score from the judges is 7.75 what is the percent error. Round the percent to the nearest tenth if necessary

Answer 1

9.7%

Explanation:

Given:

Observed score value = 8.5

Actual score value = 7.75

Required:

Percent error to the nearest tenth

SOLUTION:

Percent error = \frac{Value_{observed} - Value_{actual}}{Value_{actual} * 100 [/tex]

Percent error = \frac{8.5 - 7.75}{7.75} * 100 [/tex]

Percent error = \frac{0.75}{7.75} * 100 [/tex]

Percent error = \frac{75}{7.75} [/tex]

Percent error = 9.7 [/tex] (nearest tenth)
