Answer: 47 and 16
Step-by-step explanation:
- Make Two Equations
x + y = 63
x - y = 31
- Set one of the equations equal to one of the variables
x + y = 63
x = 31 + y
- Substitute the equation back into the other one
(31 + y) + y = 63
31 + 2y = 63
2y = 32
y = 16
- Substitute the answer back into the equation
x + y = 63
x + 16 = 63
x = 47
Answer: 33.9
Reasoning: This is due to it just being tan(72) x 11 which would give you 33.8545... but using that you would just round it up to get 33.9
This is a weighted average basically take the percentages and multiply them by the amount. The total sum is the amount you will make.
0.4(-25000) + 0.25(0) + 0.35(40000)
-10000 + 0 + 14000
4000 is the expected value
