Based on the estimated number of defective batteries and the number of batteries that were actually defective, the percent error of Jake's estimate is 20%
<h3>How to find the percent error?</h3>
The percent error of a problem can be found by the formula:
= (Expected results - Actual results) / 100%
Expected results = 12 defective batteries
Actual results = 10 defective batteries
Jake's percentage error is therefore:
= (12 - 10) / 100%
= 2 / 10 x 100%
= 0.2 x 100%
= 20%
In conclusion, the percent error of Jake's estimate is 20%.
