1.0mm$\leq$d$\leq$1.5mm is the inequality for the acceptable range of diameter

Work Step by Step

Since the target range is 1.5mm, the diameter has to be equal to the target range and either above or below it. However, the rod is acceptable if it $10^{-3}$mm which is equal $\frac{1}{10^{3}}$ = 1.0mm. Thus the diameter of the rod can be anywhere from 1.0mm to 1.5mm as it is within the acceptable range and the company's target range.
