Roulette is a casino game that involves players betting on where a ball will land on a spinning wheel. An American roulette wheel has 38 numbered slots — half of the slots from 1 to 36 are red and the other half are black. Slots 000 and 000000 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 \$1bet on a the color red. Here is the probability distribution of X: Win Lose \$1$-\$1−$1minus, dollar sign, 1 P(X), , 18, divided by, 38, 20, divided by, 38, end fraction Calculate the mean of X. You may round your answer to the nearest thousandth. E(X)= equals dollars

answer: ouch. thats difficult

step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
