Answer:

y = 4x - 8

Step-by-step explanation:

x = 1/4y + 2

-1/4y -1/4y

-1/4y + x = 2

-x -x

-1/4y= -x + 2

*-4 *-4

y = 4x - 8

Hey!

------------------------------------------------

Solution:

~Subtract x to both sides

x - x = 1/4y + 2 + (-x)

~Simplify

1/4y = 2 + (-x)

~Multiply 4 to both sides

1/4y * 4 = 2 + (-x) * 4

~Simplify

y = 8 - 4x

~Switch

y = 4x - 8

------------------------------------------------

Answer:

$\large\boxed{y~=~4x~-~8}$

An article on polygraph testing of FBI agents indicated that the probability of a false-positive (a trustworthy person who nonet

Alexandra [31]

Answer:

The variable x will follow a geometric distribution, with mean = 3 and standard deviation = 3.46.

The values for P(x) are:

$P(0)=0.25\\\\P(1)=0.1875\\\\P(2)=0.1406\\\\P(3)=0.1055\\\\P(4)=0.0791\\\\P(5)=0.0593\\\\P(6)=0.0445\\\\P(7)=0.0334\\\\P(8)=0.025\\\\P(9)=0.0188\\\\P(10)=0.0141\\\\$

Step-by-step explanation:

This kind of random variables can be descripted by the geometrical distribution.

This distribution shows the probability of having an amount of "failures" before the first "success" (or the other way).

Let x be the number of trustworthy FBI agents tested until someone fails the test. The probability of failing a test is p=0.25

Then, the probability of x is:

$P(x)=q^x\cdot p$

The values for the first x are:

$P(0)=0.75^0\cdot 0.25=0.25\\\\P(1)=0.75^1\cdot 0.25=0.1875\\\\P(2)=0.75^2\cdot 0.25=0.1406\\\\P(3)=0.75^3\cdot 0.25=0.1055\\\\P(4)=0.75^4\cdot 0.25=0.0791\\\\P(5)=0.75^5\cdot 0.25=0.0593\\\\P(6)=0.75^6\cdot 0.25=0.0445\\\\P(7)=0.75^7\cdot 0.25=0.0334\\\\P(8)=0.75^8\cdot 0.25=0.025\\\\P(9)=0.75^9\cdot 0.25=0.0188\\\\P(10)=0.75^{10}\cdot 0.25=0.0141\\\\$

This probability will be descending as the the variable x increases.

The mean is:

$\mu=\frac{1-p}{p}= \frac{1-0.25}{0.25}=\frac{0.75}{0.25}=3$

The standard deviation is:

$\sigma=\sqrt{\frac{1-p}{p^2}} =\sqrt{ \frac{0.75}{0.25^2} }=\sqrt{12}= 3.46$

Which of the following is the surface area of the right cylinder below?

Evgen [1.6K]

The formula for the surface area of a right cylinder is 2πrh + 2πr^2. r is the radius, and h is the height.

In this instance, the radius is 4, so plug that in for r. (I.E. Replace r with 4).

The formula is now 2π4h + 2π4^2.

Next, plug in the height, 8 for h.

Now we have 2π4(8) + 2π4^2, which is approximately 301.59.

The surface area is 301.59. (Unit of measure was not specified)
