Answer:
0.6170
Step-by-step explanation:
Given that a manufacturing process is designed to produce bolts with a 0.25-in. diameter.
i.e. no of bolts which are produced as per standard is X means then
X is normal with mean = 0.250 and std dev = 0.04
No of bolts tested = 36
If this mean falls outside the interval (0.230,0.270) the production would be shut down.
i.e. P(|x-25|>0.20) =production shut down probability

For number 22:
7y=8x-14 ; y=6
Plugging in y, we get:
7*6 = 8x - 14
42 = 8x-14
56 = 8x
x = 7
Comparing answers, x is, indeed 7.
