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
Answer:
its 216 cubic feet.
Step-by-step explanation:
6x6x6 is 216
It could not be 73º because if you add that to 120 then it will be more than 180 degrees, which is the total number of degrees in a triangle. Hope this helps!
Answer:
Step-by-step explanation:
In general:
Volume = (the area of the base of the figure) times (the figure's height)
Here, the area of the base is 4 square feet, the height is 2 1/2 foot = 5/2 foot
Our Volume is then:
4 square feet * 5/2 foot = 10 cubic feet
Answer:
A
Step-by-step explanation:
Remark
f and d are equal (and acute) because they are corresponding angles.
82 and f are supplementary, so we can find f
Finding f
f + 82 = 180
f = 180 - 82
f = 82
Finding d
d = f
d = 82
