Assume that the pond contains 90 fish: 64 purple, 25 green, and 1 red. A contestant pays $0.55 to randomly catch one fish and re

Answer:

The carnival is losing (on average) $0.15 on each play

Step-by-step explanation:

To find out how much the carnival wins or looses in each play one subtract the expected value (EV) from each play from the amount charged by the carnival for each play ($0.55). If the expected value is higher than what the carnival charges, the carnival is losing money.

Expected is the sum of the payouts of each bet multiplied by its likelihood:

$EV= \frac{64*0.40+25*1.15+1*9.00}{90}\\EV= 0.70$

Since the expected value is higher than $0.55, the carnival is losing money, on average, on each play:

$0.55-0.7 = -0.15$

The carnival is losing (on average) $0.15 on each play

Factor the expression completely.

RSB [31]

-9.75 + 3.25x

= -3.25(3) + 3.25(x)

= -3.25(3) - -3.25(x) notice they have the same factor of -3.25

= -3.25(3 - x)

Solve for h. –0.62 + 8.35 + 3.9h = –6.55 + 1.1h

stepan [7]

Answer:

$- 0.62 + 8.35 + 3.9h = - 6.55 + 1.1h \\ \\ 3.9h - 1.1h = - 6.55 + 0.62 - 8.35 \\ \\ 2.8h = - 14.28 \\ \\ h = \frac{ - 14.28}{2.8} \\ \\ h = \frac{ - 142.8}{28} \\ \\ h = - 5.1$

The Flip-Flop-Alot Company makes and sells flip-flops. They have one linear function that represents the cost of producing flip-

Brums [2.3K]

If we let the number of flip-flops be x in the equation and that the cost would be y ( in terms of x) and the income would be z ( in terms of x), these equations will likely intersect each other during breakeven. That is, when the total revenue that the company will gain from sales of the flip-flops just be equal with the total cost.
