The wilson manufacturing company uses a machine to stamp out parts for lawn mowers. on average, the machine will produce 7 defective parts for each 1,000 made. using a direct variation formula, determine the number of defective parts that would be expected if the machine produced 7,000 parts.

49

Step-by-step explanation:

The direct variation formula for two quantities x and y is given by :-

, where k is constant.

Let x be the number of parts produced by machine and y be the number of defective parts produced .

For x = 1,000 and y=7 , we have

Now, for x =7 ,000, the value of y will be :-

Hence, the the number of defective parts that would be expected if the machine produced 7,000 parts = 49
