The answer is below
Step-by-step explanation:
a) For a normal model the sample size has to be equal or greater than 30 so that it can be a normal distribution.
b) Given that:
μ = 11.2 minutes, σ = 4.8 minutes, n = 45
The z score determines how many standard deviations the raw score is above or below the mean. It is given by:
For x < 10 minutes
Therefore from the normal distribution table, P(x < 10) = P(z < -1.68) = 0.0465
Answer:
around 15

The answer is y = 1(x + 3)^2 - 81.
Hi!
We will solve this using proportions, like this:
3/4 cup for 8 slices of pie
x cup for 48 slices of pie
_______________________
x = ((3/4)*48)/8
x = (3*48)/(4*8)
x = 144/32
x = 4,5
You need 4 1/2 cups of white sugar for 48 slices of pie.
Hope this helps!
