Step-by-step explanation:
Given : Water use in the summer is normally distributed with


Let X be the random variable that represents the quantity of water required on a particular day.
Z-score : 

Now, the probability that a day requires more water than is stored in city reservoirs is given by:-

We can see that on comparing the above value to the given P(X > 350)= 1 - P(Z < b) , we get the value of b is 0.965.

0.583/9.33 = 0.06248
round the 0.06248 to 0.06245
25/5-0.2*5=?
1.(25/5=5)
2.(5-0.2=4.8)
3.(4.8*5=24)
4. the answer is 24
