On your next turn in a board game there is a 60% chance that you will move ahead 4 spaces and a 40% chance that you will move ba
Vika [28.1K]
The expectation value is simply obtained by multiplying the probability of each outcome by each possible value. These are then summed for each outcome to obtain the expectation value. In the board game, if there is a 60% chance that you will move 4 spaces forward (+4) and a 40% chance that you will move back 2 spaces then expected value for number of spaces is (0.6 x 4) + (0.4 x -2) = 2.4 - 0.8 = 1.6 spaces.

Determine the slope of the line 5x + 3y + 12 = 0 .
vazorg [7]
Put ur equation in y = mx + b form because the slope will be in the m position.

5x + 3y + 12 = 0
3y = -5x - 12
y = -5/3x - 4

y = mx + b
y = -5/3x + (-4)......as u can see, the number in the m position (the slope) is -5/3 <===

viktelen [127]

I can't understand this after "happening is" but let's do it unaided.

The number of ways to draw a boy first is 6.

Given that, the number of ways to draw a girl next is 10.

That's out of a total of 16 x 15 length two permutations of 16 things

p = \dfrac{6 \times 10}{16(15)} = 1/4

Answer: 1/4

What is the slope of the line that contains the points (-2,2) and (3,4)
malfutka [58]

<u><em>Answer: B. 2/5 *The answer must have a fraction.</em></u>

Explanation:

Slope-intercept form: → y=mx+b

m: represents the slope and is constant.

b: represents the y-intercept.

Used rise/run.

\frac{rise}{run}

x^1,y^1=(-2,2)

x^2,y^2=(3,4)

You had to find the slope by using formula.

Slope=\frac{y^2-y^1}{x^2-x^1}

\frac{4-2}{3-(-2)}

subtract by the numbers and add the numbers too.

\frac{4-2=2}{3-(-2)=3+2=5}

=\frac{2}{5}

Hope this helps!
