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
C = 180 - A - B
And
C = 180 - (A+B)

Brainliest answer :)) ?
A pythagoras triplet is a set of three numbers ... not just any three numbers,
but a set where the (square of one of them) is the sum of the (squares of the
other two).
If they're related in that way, then they can be the lengths of the sides of a
right triangle.
If they're not, then they can't.

Answer:
12
Step-by-step explanation:
The least common multiple of {6,8,12} is 24. This can be intuitively figured by noting that any multiple of 12 is a multiple of 6 and that 12 is 1.5x larger than 8. That means we only have so multiple 12 by 2 and 8 by 3 for them to be equal. The GCF of {20,42,72} is 2 as the prime factorization of 20 is 2x2x5 and 42 is 2x3x7. That means even without having to check 72 (which is clearly even so 2 is a factor), we know that 2 is the greatest common factor that they could share. So X/Y = 24/2 = 12
