A company produces 20,000 vacuums in one quarter. Randomly they select 600 vacuums to test. In that test sample, 10 vacuums are faulty. Predict how many vacuums will be faulty of the 20,000.
A. 600
B. 33
C. 60
D. 333
D. 333
Explanation: Set up the proportion 10/600 = V/20,000
Then cross multiply, so 600 x V = 10 x 20,000
600V = 200,000
V = 333.33
Faulty Vacuums = 333
