Question

You estimate that there are 64 marbles in a jar. The actual amount is 46 marbles. Find the percent error. Round to the nearest tenth of a percent if necessary.

Answer 1

percentage error = 39.1%

Explanation:

You estimate that there are 64 marbles in a jar. The actual amount is 46 marbles. Find the percent error. Round to the nearest tenth of a percent if necessary.

Given that You estimate that there are 64 marbles in a jar.

The actual amount is 46 marbles

Actual marbles = 46

Your estimate = 64

`\% error =(estimated - actual)/(actual)`

% error = | estimate - actual | / actual × 100%

estimate amount - actual amount = 64 - 46 = 18

`= (18)/(46) * 100\\\\=0.391* 100\\\\=39.1 \%`

Therefore, percentage error = 39.1%
