The z-score is the number of standard deviations away from the mean. We first subtract the actual score from the mean, then divide the difference by the standard deviation. In this case, our actual score is 13, so we subtract from the mean of 16, then divide by the SD of 2
(13 - 16) / 2 = -1.5

Answer:
Amount of acid = 55.1 mm (Approx)
Step-by-step explanation:
Given:
Amount of solution = 336 mm
Percentage of acid = 16.4%
Find:
Amount of acid
Computation:
Amount of acid = Amount of solution x Percentage of acid

Amount of acid = 55.1 mm (Approx)
Let that number be 'x'
So the inequality will be
- 18 + x > 22
or x - 18 > 22
