What is the median of the following data set? -5000, -4999, -4998, ..., -1, 0, 1, ..., 4998, 4999, 5000

Answer:
o
Step-by-step explanation:
the median is obvi zero
Let a, b, c represent the numbers of $8, $10, and $12 tickets sold, respectively. The problem statement gives rise to three equations:
- a + b + c = 500
- 8a +10b +12c = 4700
- a + b - 4c = 0
Solving these equations by your favorite method gives ...
... (a, b, c) = (250, 150, 100)
250 $8 tickets, 150 $10 tickets, and 100 $12 tickets were sold.
_____
After you subtract the 3rd equation from the first to find 5c=500, you can substitute c=100 into the first two equations to get two equations in two unknowns. You know several ways to solve such equations, including elimination, substitution, and graphing, at least. Cramer's method is another viable choice.

Answer:
$13
Step-by-step explanation:
First, find how much she put into the bank:
84 - 45 = $39
Then, multiply this by 2 to find how much she made, because this was half of the money she got:
39(2) = 78
Then, divide this by 6 to find how much she makes a day:
78/6 = 13
= $13
H= 13
This is because -117/ -9 equals 13
