Step-by-step explanation:
the probability that the ticket will win you 600 dollars * 1/1500 = 600/1500.
the probability that the ticket will win you 50 dollars is 50 * 5/1500 = 250/1500.
the probability that the ticket will win you 25 dollars is 25 * 20/1500 = 500/1500.
your expected value is -1 + 600/1500 + 250/1500 + 500/1500 = -.1.
the average loss for each dollar that is bet is equal to 10 cents.
hope this helped

<u>Answer:</u>
(x, y) = (-2, 2)
<u>Step-by-step explanation:</u>
We are given the following two equations which we are to solve using the substitution method:
--- (1)
--- (2)
From equation (1):
Substituting this value of x in (2) to get:
![x = [tex]x - 2y = -6\\\\(y-4)-2y=-6\\\\-y=-6+4\\\\-y=-2](https://tex.z-dn.net/?f=x%20%3D%20%5Btex%5Dx%20-%202y%20%3D%20-6%5C%5C%5C%5C%28y-4%29-2y%3D-6%5C%5C%5C%5C-y%3D-6%2B4%5C%5C%5C%5C-y%3D-2)
[/tex]
y = 2
Substituting the value of y in (1) to get x:
x = -2
Therefore, (x, y) = (-2, 2).
C+p=15
5c+7p=91
multiply 5 to 1st equation and subtract it from 2nd
multiply 5 to 1st equation to get
5c+5p=75
now subtract this from 2nd equation
thats 2p=16
so
p=8
now we find c from
c+p=15
c=7
