Answer:
The expected winning is + $2.17
Step-by-step explanation:
Here, we want to calculate the expected winnings for the game
The number of possible results are;
1,2,3,4,5,6
Probability of each value is 1/6
So expected pay off is as follows;
1/6(5) + 1/6(3) + 1/6(5) + 0
= 5/6 + 3/6 + 5/6
= 5/6 + 5/6 + 1/2 + 0
= 10/6 + 1/2 = 5/3 + 1/2 = (10 + 3)/6 = 13/6 = 2.1667
The number of rows will be a divisor of 550 such that the quotient is 3 more.
... 550 = 1×550 = 2×275 ≈ 5×110 = 10×55 = 11×50 = 22×25
Factors 22 and 25 differ by 3.
The number of rows of seats is 22.
_____
The number of seats in a row is 25.
The rational expression
![\dfrac{v^{2}+1}{v^{2}-v-6}=\dfrac{v^{2}+1}{(v-3)(v+2)}](https://tex.z-dn.net/?f=%5Cdfrac%7Bv%5E%7B2%7D%2B1%7D%7Bv%5E%7B2%7D-v-6%7D%3D%5Cdfrac%7Bv%5E%7B2%7D%2B1%7D%7B%28v-3%29%28v%2B2%29%7D)
will be undefined where the denominator is zero. Values of v that make the denominator zero are v=3 and v=-2.
Excluded values of v are -2 and 3.
It is positive 4 because you can't subtract 2-(-2)
