G=b-3 and c=29=b+g substituting the first into the second gives you...
b+(b-3)=29
2b-3=29 add 3 to both sides
2b=32 divide both sides by 2
b=16
So there were 16 boys and (29-16) 13 girls in Ms. Wong's class.

The average winning per bet is the mean or the expected value of winning a bet.
The statistical term that represents $0.94 is (c) the expected value
From the question, we understand that the gambler has an average winning of $0.94, when he places a bet of $1
This means that:
The average winning on a bet of $1 is $0.94
Average, in statistics means the mean or expected value

<u>Given </u><u>:</u><u>-</u>
- A function f(x) = - (x -17)/12
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>
- The inverse of the function .
<u>Solution</u><u> </u><u>:</u><u>-</u>
The given function is ,
f(x) = -(x-17)/12
Replace y with f(x) ,
y = -(x-17)/12
Interchange x and y ,
x = -(y-17)/12
Solve for y ,
12x = -y +17
y = -12x +17
Replace y with f-¹(x) ,
<u>Hence </u><u>the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>-12x </u><u>+</u><u>1</u><u>7</u><u>.</u>
