Question

You estimate that there are 69 marbles in a jar. The actual amount is 77 marbles. Find the percent error. Round to the nearest tenth of a percent if necessary.

Answer 1

Explanation:

Given that You estimate that there are 69 marbles in a jar. The actual amount is 77 marbles

Actual marbles = 77

Your estimate = 69

Error = difference = actual -estimate = 8

Percentage error = error/actual *100

Percent error =
`(8*100)/(77) \\=10.389\\=10.4`

So percentage error = 10.4
