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

9.7%

Step-by-step 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)

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
