Answer:

D) (0.59, 3.35)​

Step-by-step explanation:

The inequality for the thickness of the metal bars is:

[tex]|x-1.971| \leq1.38[/tex]

In order for this inequality to be true, the following conditions must be met:

[tex]x-1.971 \leq1.38\\x-1.971 \geq -1.38[/tex]

The range of thickness "x" that fits the inequality is:

[tex]x -1.971 \leq1.38\\x\leq 3.351\\x-1.971 \geq -1.38\\x\geq 0.591\\0.59\leq x\leq 3.35[/tex]

Thickness ranges from 0.59 to 3.35 units.
