Let X be the random variable representing the number
of coins that Matt set aside after three flips.
We have to run n from 0 to 100 and m from 0 to (100-n),
Find the binomial law, then compute the mean like this:

Step-by-step explanation:
The answer is the last one option: y+6=-34(x+2). I told you the reason in the other similar question.
Answer:
C (-6, 2)
Step-by-step explanation:
in order to solve this system of equation, we would say that let
y = 5x + 32................................equation 1
y = -4x - 22.........................................equation2
substitute equation 1 into equation 2
we have,
5x + 32 = -4x - 22
combine the like terms
5x +4x + 32 = -22
9x = -22-32
9x = - 54
divide both sides by the coefficient of x which is 9
9x/9 = -54/9
x = -6
put x =-6 into equation 1
y = 5x + 32................................equation 1
y = 5(-6) + 32
y = -30 + 32
y = 2
therefore the value of x and y is -6 and 2 respectively
