Question

A quality control inspector is in charge of inspecting drill bits that are produced on an assembly line. The diameter of a drill bit can be modeled by the equation |x − 0.525| = 0.01. Show your work in solving the equation to determine the minimum and maximum diameters of the drill bits.

Answer 1

So, let's use other numbers so you can do this problem:

|x - .5| = .1
is the same as |x - .5| <= .1
which is the same as |x - .5| <= .1
which is the same as -.1 <= x - .5 <= .1
which is -.1 + .5 <= x <= .1 + .5
same as .4 <= x <= .6

So in words: As the minimum that the diameter can be is .4 and the maximum that it can be is .6.

Substitute your values to come up with similar results.
