Answer:
Step-by-step explanation:
volume of cylinder=V=πr^2h
given diameter=7 feet
radius=7/2 ft
height=16ft
v=π×7/2×7/2×16
=12.25×16×π
=196π

Answer:
36
Step-by-step explanation:
First: add 24and 30 to get 54
Second: subtract 54 from 90
Third: then you get 36 as an answer
Let X be the number of boys in n selected births. Let p be the probability of getting baby boy on selected birth.
Here n=10. Also the male and female births are equally likely it means chance of baby boy or girl is 1/2
P(Boy) = P(girl) =0.5
p =0.5
From given information we have n =10 fixed number of trials, p is probability of success which is constant for each trial . And each trial is independent of each other.
So X follows Binomial distribution with n=10 and p=0.5
The probability function of Binomial distribution for k number of success, x=k is given as
P(X=k) = 
We have to find probability of getting 8 boys in n=10 births
P(X=8) = 
= 45 * 0.0039 * 0.25
P(X = 8) = 0.0438
The probability of getting exactly 8 boys in selected 10 births is 0.044
A is equal to 1100 miles
B is equal to 3300 miles
You take 1650 and divide by 3 which is 550, that is 1 hour is equal to 550 miles.
If the choices are the following:
The legs are congruent.
The base angles are congruent.
The bases are | |.
<span>The diagonals are congruent.
Then , to prove </span>ACD ≅ BDC by SSS I would use The base angles are congruent.
<span>This is sufficient to prove the triangles are congruent.</span>
