4n-2n+4=-1+17
2n+4=-1+17
-1+17=16
2n+4=16
Move + 4 to the other side. Sign changes from +4 to -4
2n+4-4=16-4
2n=12
Divide by 2 for 2n and 12
2n/2=12/2
n=6
Check answer by using substitution method
4(6)-2(6)+4=16
24-12+4=16
12+4=16
16=16
Answer : n=6

The answer is B.
Step-by-step explanation:
Since such a frequent control is applied on the production line, 20 of the metal discs are inspected every hour, which means that any error will be corrected and prevented and that, as stated in the question, leads to a uniform distribution of the diameters of the metal discs.
According to the information given in the question and the central limit theorem, the observed distribution type will be normal distribution which means that the collected data will be consisted with respect to the mean and most of the data points will be around the mean point.
I hope this answer helps.
