Question

Jake is a factory manager for a company that produces batteries. Occasionally, some are found to be defective. Based on previous results, Jake
estimates that 12 batteries will be defective for a certain month. However, 10 were actually defective. What is the percent error of Jake's estimate?

Answer 1

Answer:
20%

Explanation:
The formula for percent error is (accepted value - experimental value) / accepted value x 100. If you want to check plug that formula into a calculator. Work is shown below. 10-12 = -2. -2/10 = -0.2. -0.2 x 100 = -20. -20 x -1 = 20
