Simplify (Y^2+7y+6)/(6y^2-6)

Arisa [49]

Answer:

$\frac{y + 6}{6(y - 1)}$

Step-by-step explanation:

The given expression is

$\frac{ {y}^{2} + 7y + 6}{6 {y}^{2} - 6}$

The numerator is a quadratic trinomial and the denominator is different of two squares when 6 is factored.

We factor both the numerator and the denominator to obtain;

$\frac{ (y + 6)(y + 1) }{6(y - 1)(y + 1)}$

Cancel out the common factors to get:

$\frac{y + 6}{6(y - 1)}$

This is the simplest form since, we cannot simplify this further.

Find the area of the regular polygon. Give the answer to the nearest tenth.

Molodets [167]

A regular dodecagon is a polygon with 12 equal sides.
Length of each side = 108/12 = 9 cm.

Length of the apothem = (9/2)/tan 15 = 9/2tan 15 = 16.79 cm

Area of each triangle = 9/2(16.79) = 75.57 cm^2

Therefore, area of the dodecagon = 12(75.57) = 906.9 cm^2

A fair four-sided die has two faces numbered 0 and two faces numbered 2. Another fair four-sided die has its faces numbered 0, 1

Mandarinka [93]

The two dice have PMFs

$P(X=x)=\begin{cases}\dfrac12&\text{for }x\in\{0,2\}\\\\0&\text{otherwise}\end{cases}$

$P(Y=y)=\begin{cases}\dfrac14&\text{for }y\in\{0,1,4,5\}\\\\0&\text{otherwise}\end{cases}$

The sum of the two rolls can take on 8 different values:

$W=\begin{cases}0&\text{if }x=0,y=0\\1&\text{if }x=0,y=1\\2&\text{if }x=2,y=0\\3&\text{if }x=2,y=1\\4&\text{if }x=0,y=4\\5&\text{if }x=0,y=5\\6&\text{if }x=2,y=4\\7&\text{if }x=2,y=5\end{cases}$

The outcome of either roll is independent of the other, so that

$P(X=x\text{ and }Y=y)=P(X=x)P(Y=y)$

a. Then PMF of $W$ is

$P(W=w)=\begin{cases}\dfrac12\cdot\dfrac14=\dfrac18&\text{for }w\in\{0,1,2,3,4,5,6,7\}\\\\0&\text{otherwise}\end{cases}$

b. The histogram is nothing special, same as the discrete uniform distribution over the interval [0, 7].
