Roulette is a casino game that involves players betting on where a ball will land on a spinning wheel. An American roulette whee

l has 38 numbered slots — half of the slots from 1 to 36 are red and the other half are black. Slots 0 and 00 are both green.
Suppose that a player bets $1 on the color red. If the ball lands in a red slot, the player gets their initial $1 back plus a payout of $1. If the ball doesn't land in a red slot, they lose their $1 bet. Let X= the player's net gain from a $1 bet on a the color red. Here is the probability distribution of X:


Win Lose

X=net gain $1 -$1

P(X) 18/38 20/38

olasank [31]

Answer:

C(x) = 0.1x+23000

Step-by-step explanation:

Given that a company sells doughnuts. They incur a fixed cost of $23000 for rent, insurance, and other expenses. It costs $0.1 to produce each doughnut. The company sells each doughnut for $0.2.

Let X be the no of units produced

Then we have variable cost = 0.1x

Fixed cost = 23000 (irrespective of value of x)

Total cost

C(x) = 0.1x+23000

where C represents the total cost and x no of units produced.

Revenue function would be

R(x) = 0.2x assuming all doughnuts are sold.

Profit function would be

P(X) = 0.1x-23000
