Answer:
fg(-2)=f(5×-2+4)=f(-6)=8-10×-6=8+60=68
Answer: 0.71221
Step-by-step explanation:
We know that for binomial distribution :-
, where p is the proportion of success in each trial and n is the sample size.
Given : p=0.80 ; n=20
Then, 
Let X be the binomial variable.
z-score : 
For x=9

For x=17

Then, the probability that more than 9 but less than 17 of the hotels in the sample is given by :-

Hence, the probability that more than 9 but less than 17 of the hotels in the sample = 0.71221
He can fill 11 bags with 5 in each one.
Answer:
Step-by-step explanation:
11 bakers makes 89 pretzels in 2.5 hours
11 bakers makes 35.6 pretzels in 1 hour
1 baker makes 3.23636 pretzels in 1 hour
so, 5.75 bakers in 1.5 hours at 3/23636 pretzels per hour will make....
5.75* 1.5 * 3.23636 = 27.9136 pretzels
