mariarad [96]

Answer:

0.46875 ; 1.133 ; $17 ;19.27

Step-by-step explanation:

Number of slots = 32

0, 00, {1,.. 30}

Odd outcomes = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29}

1.) probability of winning :

P(winning) = number of odd outcomes / tot possible outcomes

P(winning) = 15 / 32 = 0.46875

2.)

Odds against winning :

Number of losing outcomes / number of winning outcomes

Not odd numbers / odd numbers = 17 /15 = 1.133

C.)

Payoff odd = 1:1

If bet value = $17 ;

Profit made on winning = $17 * 1 = $17

d.)

If Payoff odd = odd against winning = 17 / 15

Profit on $17

17/ 15 * 17

(1.1333333) * 17

= 19.27

For the given functions f and g, find the indicated composition:

mihalych1998 [28]

Answer: x

<u>Step-by-step explanation:</u>

g(x) = 4x + 10 f(x) = $\frac{x - 10}{4}$

to find g(f(x)), replace "x" in the g(x) equation with what f(x) equals. Another way of writing g(f(x)) for this problem is: g( $\frac{x - 10}{4}$ ).

g(f(x)) = 4 $(\frac{x - 10}{4})$ + 10

= x - 10 + 10

= x
