Answer:
5.5 is the median, and the mode is 10.625
Step-by-step explanation:
Median means the number in the middle, since there is an even ammount of numbers, it comes down to 5 and 6 and in the middle of that is 5.5
mode is when you add all of the numbers together and divide it by how many numbers it has and you have your answer

Answer:
22 people
Step-by-step explanation:
Using the concept of a Venn Diagram, you place the 3 people in the intersection. Then, you subtract the three from both groups to keep the balance.
Since you said "or", you just add the entirety of the population.
Answer:
y = -6, x =2
Step-by-step explanation:
To solve by elimination, you have to line both equations up together. Then, you multiply both equations until one variable is removed.
2x+y = -2
5x + 3y = - 8
There are many different ways to solve an elimination problem, but generally you should look for the simplest route. Here, I would multiply the top equation by -3.
-6x -3y = 6
5x +3y = -8
Imagine you are adding the two equations together. You end up with
-x = -2
Then solve for x. In this situation, it is fairly simple. Take out a factor of -1.
x = 2
Finally, choose one of your beginning equations and plug your new-found x value back into the equation.
2(2) +y = -2
4 + y = -2
y = -6
