Question

25. A manufacturer makes a certain machine part that measures 26.4 cm in length. A part will passinspection if it is no more than 0.03 cm shorter than 26.4 cm or no more than 0.03 cm longer than26.4 cm. What is the shortest and longest measures that can pass inspection? How do you know?

Answer 1

Since the expected measure of the product is 26.4 cm, and it can be 0.03cm longer or shorter, we need to add and substract 0.03cm to the expected measure to know what is the shortest and lengest measures that can pass inspection.

Shortest:

$26.4cm-0.03cm=26.37cm$

Longest:

$26.4cm+0.03cm=26.43cm$

Tha shortest measure is 26.37cm and the longest is 26.43cm
