Answer:
(Correct to 4 decimal places)
Step-by-step explanation:
The probability of a continuous normal variable X found in a particular interval [a, b] is the area under the curve bounded by x=a and x=b and is given by:

Using a calculator,
Answer: 27.5 is the amount of pages Carrie can read an hour.
Step-by-step explanation: you want to find how many times 12 can go into and hour because that’s the rate she reads 5 1/2 pages. 60/12=5 now that you know it goes in five times do amount of pages she reads times five so, 5 1/2*5=27.5
