Answer 1

Answer:

percentage error = 39.1%

Step-by-step 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

$\% error =\frac{estimated - actual}{actual}$

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

estimate amount - actual amount = 64 - 46 = 18

$= \frac{18}{46} \times 100\\\\=0.391\times 100\\\\=39.1 \%$

Therefore,  percentage error = 39.1%
