Question

2.Ainsley thought there were 25 students in her math class, but there were actually 27 students. What is

her percent error?

Answer 1

To find the percent error, we need to first calculate the difference between Ainsley's estimate and the actual value. In this case, the actual value is 27 students, while Ainsley's estimate is 25 students. The difference between these two values is 27 - 25 = 2 students.

Next, we need to find the absolute value of this difference. Since the difference is 2 students, the absolute value of the difference is simply 2.

Finally, we need to divide the absolute value of the difference by the actual value and multiply the result by 100 to find the percent error. In this case, the percent error is (2 / 27) * 100 = 7.4%. Therefore, Ainsley's percent error is 7.4%
