Answer:
The answer is explained below
Step-by-step explanation:
We have the following formulas:
from binomial distibution: P (X = x) = (nCx) * (p) x * (1-p) n-x
from normal distribution: P (X <= x) = (x-np) / sqrT (np (1-p))
Now, n = 25 and p (0.5, 0.6, 0.8), we replace in the formulas and we are left with the following table:
P P(15<=X<=20) P(14.5<=X<=20.5)
0.5 0.2117 is less than 0.2112
0.6 0.5763 is less than 0.5685
0.8 0.5738 is greater than 0.5957
Pete needs 10.5 ounces of turkey.
Step-by-step explanation:
Given,
Number of friends = 2
One for Pete.
Total sandwiches to be made = 2+1 = 3
Quantity of turkey in one sandwiches = 3.5 ounces
For finding the quantity of turkey for three sandwiches, we will multiply.
Turkey for 3 sandwiches = 3*3.5 = 10.5 ounces
Pete needs 10.5 ounces of turkey.
