A cylinder has a height of 4 meters and a diameter that is 3 times the measure of the height. Using 3.14 for pi, which of the fo

ANTONII [103]

To calculate the volume of a cylinder, you will use the formula:
area = π • r² • h.

To start off, we need to figure out the diameter. To figure out the diameter of the cylinder we will multiply.
3 • 4 = 12

Next we will divide since the radius is half of the diameter.
12 ÷ 2 = 6

Fill in the formula and solve.
Area = π • r² • h
Area = 3.14 • 6² • 4
Area = 3.14 • 36 • 4
Area = 113.04 • 4
Area = 452.16

Hope this Helped!

Explain how to find cot, sec, csc

Helga [31]

Answer:

The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x . The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x . = tan 5π 4

Calculating conditional probability

Complete Question

Calculating conditional probability

The usher at a wedding asked each of the 80 guests whether they were a friend of the bride or of the groom.

Here are the results:

Bride :29

Groom :30

BOTH : 20

Given that a randomly selected guest is a friend of the groom, find the probability they are a friend of the bride.

P (bride | groom)

Answer:

The probability is $P(B|G) = \frac{2}{3}$

Step-by-step explanation:

The sample size is $n = 80$

The friend of the groom are $G = 30$

The friend of the groom are $B = 29$

The friend of both bride and groom are $Z = 20$

The probability that a guest is a friend of the bride is mathematically represented as

$P(B) = \frac{29}{80}$

The probability that a guest is a friend of the groom is mathematically represented as

$P(G) = \frac{30}{80}$

The probability that a guest is both a friend of the bride and a friend of the groom is mathematically represented as

$P(B \ n \ G) = \frac{20}{80}$

Now

$P(B|G)$ is mathematically represented as

$P(B|G) = \frac{P(B \ n \ G)}{P(G)}$

Substituting values

$P(B|G) = \frac{\frac{20}{80} }{\frac{30}{80} }$

$P(B|G) = \frac{2}{3}$

If the population of a state was 4702644 how many representatives should that state have

WARRIOR [948]

There is not an exact way to answer that question. The number of representatives each state has is determined by the population. However, the total number of house representatives has been capped at 435 since 1913. Currently, the ratio of constituents to representatives is 700,000 to 1. So if you divide the total population by 700,000 you will have an approximation of the number of representatives.

What are two numbers multiplied together to get 15 but add to be 12?

KiRa [710]

So x times y=15
x+y=12
solve
x+y=12
subtract x from both sides
y=12-x
subsitute
xy=15
x(12-x)=15
distribute
12x-x^2=15
subtract (12x-x^2) from both sides
0=x^2-12x+15
use quadratic formula which is
x= $\frac{ -b+/- \sqrt{b^{2}-4ac} }{2a}$
where you have
0=ax^2+bx+c
so
a=1
b=-12
c=15
subsitute
x= $\frac{ -(-12)+/- \sqrt{-12^{2}-4(1)(15)} }{2(1)}$
x= $\frac{ 12+/- \sqrt{144-60} }{2}$
x= $\frac{ 12+/- \sqrt{84} }{2}$
x= $\frac{ 12+/- 2\sqrt{21} }{2}$
x=6+/- $\sqrt{21}$
x=6+ $\sqrt{21}$ or 6- $\sqrt{21}$ or aprox
x=10.5826 or 1.41742
the numbers are 10.5826 and 1.41742
