Answer:
This states that the probability of the occurrence of two independent events is the product of their individual probabilities. The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25.
Step-by-step explanation:
The probability of getting 2 heads with 2 coins can be broken into 2 steps:
The first coin must show Heads AND
the second coin must show Heads.
p(h,h)= P(H) <----- and means multiply
P(H) x P(H)= 1/2 x 1/2 =1/4
Answer:
B
Step-by-step explanation:
The slope is rise over run, meaning it is 3/4. The y-intercept is 2, making the equation y = (3/4)x + 2
Good evening
Answer:
Step-by-step explanation:
g(x) = -20
⇔
3x-1 = -20
⇔
3x = -20 + 1
⇔
3x = -19
⇔
x = -19/3

The picture isn’t clear enough
Answer:
Since both equations are equal to y, we can set them equal to each other.
y =-3x +8
y = -5x -2
-3x +8 = -5x -2
Solve for x.To do this, we need to get x by itself. First, move all the numbers to one side of the equation, and all the variables to the other.
-3x +8 = -5x -2
Add 5x to both sides
-3x+5x +8=-5x+5x -2
2x+8=-2
Subtract 8 from both sides
2x+8-8 = -2-8
2x=-10
Now, all the numbers are on one side, with the variables on the other. x is not by itself, it is being multiplied by 2. To undo this, divide both sides by 2
2x/2= -10/2
x= -5
Now, to find y, substitute -5 in for x in one of the equations.
y = -5x -2
y= -5(-5) -2
y=25-2
y=23
Put the solution into (x,y)
<u><em>The solution is (-5, 23)</em></u>
