Cylinder volume formula:

V=πr^2h

Substitute given values into the formula

Note: use 3.14 for pi

Diameter is twice the radius, so if diameter is 8 then radius is 4

371.776 = (3.14)(4^2)h

Use h for height because we don't know the height

Okay, so let's try to get the h by itself on the left side of the equation

So begin by getting rid of 3.14 by dividing it by both sides

371.776/3.14 = 118.4

3.14/3.14 = 1 (don't put 1, just remove the 3.14 from the right side)

So now we have:

118.4 = 4^2(h)

Now we can get rid of 4^2

Start by actually squaring it and then divide it from both sides

118.4 = 16(h) (4^2 = 16)

118.4/16 = 7.4

16/16 = 1 (dont put 1, just drop it)

So now we have

7.4 = h

Now we have h by itself! So h = 7.4

let's  test it by putting it in the cylinder volume formula

V = πr^2h

371.776 = (3.14)(4^2)(7.4)

371.776 = (3.14)(16)(7.4)

371.776 = 50.24(7.4)

371.776 = 371.776

7.4 is your answer, if you have any questions, feel free to ask

Suppose that on the average, 7 students enrolled in a small liberal arts college have their automobiles stolen during the semest
strojnjashka [21]

Answer:0.9991

Step-by-step explanation:

The Poisson distribution probability formula is given by :-

P(X=x)=\dfrac{e^{-\lambda}\lambda^x}{x!}, where \lambda is the mean of the distribution and x is the number of success

Given : \lambda=7

The probability that more than 1 student will have his automobile stolen during the current semester is given by :-

P(x\geq1)=1-P(x=0)=1-(\dfrac{e^{-7}7^0}{0!})\\\\=1-e^{-7}=0.99908811\approx0.9991

Hence, the  probability that more than 1 student will have his automobile stolen during the current semester =0.9991

A box of candy hearts contains 52 hearts, of which 19 are white, 10 are tan, 7 are pink, 3 are purple, 5 are yellow, 2 are orang
laiz [17]

<u>Answer-</u>

a. Probability that  three of the candies are white = 0.29

b. Probability that three are white, 2 are tan, 1 is pink, 1 is yellow, and 2 are green = 0.006

<u>Solution-</u>

There are 19 white candies, out off which we have to choose 3.

The number of ways we can do the same process =

\binom{19}{3} = \frac{19!}{3!16!} = 969

As we have to draw total of 9 candies, after 3 white candies we left with 9-3 = 6, candies. And those 6 candies have to be selected from 52-19 = 33 candies, (as we are drawing candies other than white, so it is subtracted)

And this process can be done in,

\binom{33}{6} = \frac{33!}{6!27!} =1107568

So total number of selection = (969)×(1107568) = 1073233392

Drawing 9 candies out of 52 candies,

\binom{52}{9} = \frac{52!}{9!43!} = 3679075400

∴P(3 white candies) = \frac{1073233392}{3679075400} =0.29



Total number of ways of selecting 3 whites, 2 are tans, 1 is pink, 1 is yellow, and 2 are greens is,

\binom{19}{3} \binom{10}{2} \binom{7}{1} \binom{5}{1} \binom{6}{2}

=(\frac{19!}{3!16!}) (\frac{10!}{2!8!}) (\frac{7!}{1!6}) (\frac{5!}{1!4!}) (\frac{6!}{2!4!})

=(969)(45)(7)(5)(15)=22892625

Total number of selection = 3 whites + 2 are tans + 1 is pink + 1 is yellow + 2 greens = 9 candies out of 52 candies is,

\binom{52}{9}=\frac{52!}{9!43!} =3679075400

∴ P( 3 whites, 2 are tans, 1 is pink, 1 is yellow, 2 greens) =

\frac{22892625}{3679075400} = 0.006
