Step-by-step explanation:
Let x = number of half-gallons the store bought
(x-15) is the number of half-gallons the store sold
Profit = Income - Cost
$65.72 = (x-15)*3.96 - (x)2.60
65.72= 3.96x - 59.40 - 2.60x [distribute]
125.12 = 1.36x [collect terms]
92 = x
Answer:
The game's expected value is of -$1.5.
Step-by-step explanation:
Expected value:
Probability of each outcome multiplied by the outcome.
One out of 6 sides is 2:
1/6 probability of the player earning 45 - 9 = $36.
5/6 probability of the player losing $9. So
![E = 36\frac{1}{6} - 9\frac{5}{6} = \frac{36 - 45}{6} = -\frac{9}{6} = -1.5](https://tex.z-dn.net/?f=E%20%3D%2036%5Cfrac%7B1%7D%7B6%7D%20-%209%5Cfrac%7B5%7D%7B6%7D%20%3D%20%5Cfrac%7B36%20-%2045%7D%7B6%7D%20%3D%20-%5Cfrac%7B9%7D%7B6%7D%20%3D%20-1.5)
The game's expected value is of -$1.5.
