An air-conditioner manufacturer randomly samples 50 units and finds that 2 are defective. the company ships 1200 units each month. which is the best prediction for the number of defective units in the monthly shipment? 25 24 48 50

48

First, you have to set two fractions so that they're equal, we can set it up so that it's defective/total, so then we have 2/50=x/1200

Now, we cross multiply so that it's 2400=50x

Next, we divide both sides by 50, so that it's 2400/50 =x

One trick we can do is cross out the mutual 0's, so now it's 240/5, which is 48
