Question

A factory produced 5720 microchips in a day. A quality control employee sampled 60 of those microchips and found that 9 of them were defective. About how many microchips made that day were defective? You must show your work to receive credit.

Answer 1

Answer: The answer is 858 were defective

Explanation:

so first you want to divide the amount they found defective in the sample group "9" by the sample group "60" and that gives you 0.15

next you take 0.15 and multiply it by the total microchips "5720" and you get 858 that were defective

i hope this helps
