Zeros: x = 2, x = 4

Turning point: (halfway between the zeros) x = 3, y = -1

y-intercept: where x=0, at f(0) = 8.

Axis of symmetry: the vertical line through the turning point: x = 3.

Small cubes with edge lenghts of 1/4 will be packed into the rectangular prism how many small cubes will be needed to completley
Olegator [25]

Answer:

9216

Step-by-step explanation:

number of small cubes that would fill the prism = volume of prism / volume of small cubes

volume of a prism = length x width x height

3 x 6 x 8 = 144

volume of cube = length³

(1/4)³ = 1/64

144 ÷ 1/64

144 x 64 = 9216

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].
