(1/2 of 24) •9
12•9
108
This got extremely messy so I apologize but I believe the correct answer is 80 cm³

Answer:
d) f(x) = 5x + 2
Step-by-step explanation:
First we need to identify the variables and how they fit into the equation. in this case we know that the equation is f(x) = mx + b where f(x) is the total cost, m is the hourly cost, x is the number of hours bowled, and b is the price of the shoes.
Now, we need to solve for the hourly cost, so to do this we plug in all the known information to get 12 = m(2) + 2
To solve we need to isolate the variable by first subtracting 2 on both sides to get 10 = m(2) and then dividing both sides by 2 to get 5 = m.
Finally, since we now know that the hourly cost is $5 we can plug this information back into the equation to get f(x) = 5x + 2
This is a permutation (without replacement) so the probability is the probability of the first event times the probability of the second event. The equation would be ((x)/16)*((x-1)/(16-1))=1/12 don't ask me how I got this I'm not even sure myself. Algebra will give you an answer of x=5 or x=-4 and there can't be -4 girls in the class so there must be 5 girls.
