F(x) : |x|

1 answer:

4 0

-2•f(x+1)+6 = -2 |x+1| +6, which is NOT g(x).

-2•f(x+1)+3 = -2 |x+1| +3, which IS g(x).

Side note: you’re writing g(x) in terms of f(x), because f(x) is in the answer.

If you want to write f(x) in terms of g(x), then g(x) would be in the answer.

A roulette wheel has the numbers 1 through 36, 0, and 00. A bet on five numbers pays 6 to 1 (that is, if one of the five numbers

tatiyna

Answer:

5 cents

Step-by-step explanation:

So the roulette wheel would have a total of 38 numbers, which means 38 different possible cases. Since you are allowed to bet on 5 numbers, the chance to win this is 5 out of 38 and to lose this is 33 out of 38.

If you win, you get 1 + 6 = 7 dollar, and if you lose, you lose 1 dollar.

Therefore the expected amount out of this game is:

$E = 7\frac{5}{38} - 1\frac{33}{38} = \frac{35}{38} - \frac{33}{38} = \frac{2}{38} = \frac{1}{19} = \$0.0526$
