Step-by-step explanation:
For the mean find the average by adding all of the numbers up and dividing by the number of numbers in the set.
For the median arrange the numbers in order of least to greatest then find the middle number if there is two add them together and divide by two.

Step-by-step explanation:
Given two variables (say x and y); the constant of proportionality is the ratio between these to variables.
Illustration; y is directly proportional to x
The above statement can be represented as:
![y\ \alpha\ x](https://tex.z-dn.net/?f=y%5C%20%5Calpha%5C%20x)
When converted to an equation, you get
![y\ =k x](https://tex.z-dn.net/?f=y%5C%20%3Dk%20x)
k, in the above equation, represents the constant of proportionality
Divide both sides by x to solve for k
![k = \frac{y}{x}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7By%7D%7Bx%7D)
Take for instance: ![y = 3x](https://tex.z-dn.net/?f=y%20%3D%203x)
Divide both sides by x
--- 3 is the constant of proportionality
Answer:
2
Step-by-step explanation:
Take 3-1=2. There is your answer!
Answer:
x-10
Step-by-step explanation:
you have to do what is in the parenthesis first. Do distributive property to
-(x-8)
-(x)-(-8)= -x+8
now you have 5-(3-x+8)
Do distributive property again
5-3+x-8
x-8+2
x-10
hope this helps ~D~
