In a random sample of 750 bowling balls at a manufacturing plant, four were found to have manufacturing defects or imperfections. If there are 4,125 bowling balls being produced in the current run, how many of them could be expected to have defects or imperfections?

The skating rink rented 872 pairs of skates during april and may.why? : if the skating rink rented three times the pair of skates in april during may, they rented 654 skates. 218 x 3 = 654then, if they want to know how many they rented during both april and may, then you just add 654 (may) and 218 (april) to give you 872 pairs of skates for both months.654 + 218 = 872hope this !

Solution: = 2 ( 13 + 4 )= 2 ( 17 )= 34hope this ! < 3
