Answer:
- | x - 11.93 | ≤ 0.02
- 11.91 ≤ x ≤ 11.95
Step-by-step explanation:
Error is the difference from the nominal value, hence the nominal value is what is subtracted from x. We want the magnitude of that difference, | x-11.93 |, to be less than the maximum error value, 0.02, so the inequality is ...
|x -11.93| ≤ 0.02
__
We can solve this by "unfolding" it, then adding 11.93:
-0.02 ≤ x -11.93 ≤ 0.02
11.91 ≤ x ≤ 11.95
