It shows how the big chunk of 40 tiles can be divided into 10 equal parts of 4, so I'd say this shows 40:10

For the wheel pictured on the right, assume that a person spins the pointer and is awarded the amount indicated by the pointer.

Anuta_ua [19.1K]

The expectation value is given by:

$EV=\sum_{i\mathop{=}1}^nx_iP(x_i)$

In this case we just have two options, each with probability 1/2, and the values of x are 2 and 9; then we have:

$\begin{gathered} EV=(2)(\frac{1}{2})+(9)(\frac{1}{2}) \\ EV=2+\frac{9}{2} \\ EV=\frac{13}{2} \\ EV=6.5 \end{gathered}$

Therefore, the expectation is $6.5

What is the slope of the line passing through the points (−1, 3) and (4, −7) ?

alexira [117]

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

in this problem we have

$A(-1,3)\ B(4,-7)$

substitute in the formula

$m=\frac{-7-3}{4+1}$

$m=\frac{-10}{5}$

$m=-2$

therefore

<u>the answer is the option A</u>

$m=-2$
