estimated that she would het an 85% on her next math quiz her acutal quiz score was 93% what was the percent error round to nearest tenth

The percent error rounded to the nearest tenth is 8.6%.

Step-by-step explanation:

The general equation for percent error is as follows: percent error = [ (experimental value - actual value) / actual value] x 100. In this problem, her experimental value, or the expected score was 85%. However, her actual score was 93%. When we subtract the two values, we get a difference of 8 and when we divide this number by the actual value of 93, we get a quotient of. 086. Multiplying this answer by 100 will give a final percentage of 8.6%.
