Hello! :)
We can use the following area to solve for the area of the trapezoid pictured:
Where:
h = height
b1 = bottom base
b2 = top base
Plug in the given values:
Simplify:
Outcome on winning = $100 - $20 = $80
Outcome on losing = $20
Probability of winning = 1/6
Probability of losing = 5/6
Expected Value = 1/6 (80) +5/6(-20) = -3.333
This shows on average from each game, the game earns $ 3.333.
So, if 1000 such games are played, the game will earn 1000 x 3.33 = $3330
So, the answer to this question is option A
Step-by-step explanation:
First multiply
9w - 18 = - 18
9w = - 18 + 18
9w = 0
w = 0 / 9 = 0
w = 0
Answer:
Average: 26.223529411764706 (Please round to the place value necessary since it does not say in the question.)
Step-by-step explanation:
We first find the number of items sold: 170
Then we find the total cost: 4458
We then divide 4458 by 170
We end up with the answer 26.223529411764706. (Please round to the place value necessary since it does not say in the question.)
Answer:
Ф = CO/(6 units)
Step-by-step explanation:
The formula for arc length is s = rФ, where Ф is the central angle. This can be solved for Ф, the central angle:
arc length
Ф = ------------------
radius
If the given arc length is represented by CO, then the central angle is
Ф = CO/(6 units)
