Answer:
Step-by-step explanation:
Your equation is: 
You also know that x = -3 and y = 2. You can rewrite the equation by substituting x and y with their actual values:
First, you want to do the exponentiation (meaning you want to calculate
and
parts).
equals 9 and
equals 16.
So the equation now is:

Now you want to do multiplication.
equals 36 and
equals 32. So you're left with:

Which equals 68.
Answer:
75%
Step-by-step explanation:
To find how much percent of the team won, you have the event over the sample space.
So n(E)/n(S) = 63/84 = 3/4 = 0.75 = 75%
Feel free to comment if you have any questions! :D
12 minus 15% is 10.20 so you have $2.80 per hour so 2.80 per hour times 250 hours gives you $700
