Answer: 0.965
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.

Answer:
1050
Step-by-step explanation:
1. divide using long division
put 2 outside and the 2100 inside
then from there 2 goes into 2 once so put that on top. Next 2 cant go into one so put a zero above the one. After that 2 goes into 10 5 times so put a 5 above the first zero in 2100. Lastly 2 goes into zero 0 times so put a zero above the second zero.
Answer:
5+ 20 is the first thing that you do in the equation you do 5+20x3 then you do minus 12 then you can solve the equation straight across. you follow the rule PEMDAS. parenthesis, exponents, multiplication, division, addition, subtraction.
