Answer:
-18
Step-by-step explanation:
Hope it helps....................................................
use s=r0
but first convert 360 degree to radian
you will get 6.284 radian
then you substitute and get the answer!
12= r (6.284)
r= 1.91 cm
Answer:
The volume of cylinder is:
49806.06 ft^3
Step-by-step explanation:
We are given a right circular cylinder with:
Height(h)=
and a diameter is 
times it's height.
i.e. 
times it height.
i.e. the diameter is given as:
We know that the radius of cylinder is half the diameter.
Hence, radius(r) of cylinder is:
The volume(V) of cylinder is given by:
Hence, the volume of cylinder is:
49806.06 ft^3
Answer: 2.50 is the fee he must pay before the taxi takes him anywhere
Step-by-step explanation: since it is an add on, and it is not multiplied by the variable, we know this is a one time expense, meaning it is the base charge.
The answer is A

There is 70.7% chance that at least one but at most two adults in the sample believes in the ghost

1.14≅1
There will be one adult out of three we expect to believe in the ghost
Step-by-step explanation:
The probability distribution is constructed using binomial distribution.
We have to construct the probability distribution of the number adults believe in ghosts out of three adults. so,
x=0,1,2,3
n=3
p=probability of adults believe in ghosts=0.38
The binomial distribution formula
nCxp^xq^n-x=3cx0.38^x0.62^3-x
is computed for x=0,1,2,3 and the results depicts the probability distribution of the number adults believe in ghosts out of three adults.
x P(X)
0 0.238
1 0.438
2 0.269
3 0.055
11.
P(at least one but at most two adults in the sample believes in the ghost )= P(x=1)+P(x=2)=0.437+0.269=0.707
P(at least one but at most two adults in the sample believes in the ghost )=70.7%
12. E(x)=n*p
here n=3 adults and p=0.38
E(x)=3*0.38=1.14
so we expect one adult out of three will believe in the ghosts.
