Robert is inspecting a shipment of 22-inch pipes. The lengths of the pipes may vary by 1%. What is the range of allowable lengths of the pipes?

Question

*PLEASE HELP*!!!!!!!!!

Answer 1

1% of 22 = .01(22) = .22

the pipes within 1% of 22 will be from 21.78 to 22.22 inches

22 +/- .22 = 22-.22 to 22+.22 = 21.78 to 22.22
