Answer:
 Finding the average is a very straightforward concept. If you have a set of numbers, the average is found by adding all numbers in the set and dividing their sum by the total number of numbers added in the set.
example;
16, 17, 5, 27, 30, 20, 4, 1, 19, 9
add all 10 of these numbers together
16 + 17+ 5+27+30+4+1+19+9 = 148
divide 128 by 10
148 / 10 = 14.8
14.8 is the average 
 
        
             
        
        
        
When you bisect something, you cut it into two equally sized pieces. (from Latin: "bi" = two, "sect" = cut)
Bisecting an interval creates two smaller intervals each with half the length of the original interval. Some examples:
• bisecting [0, 2] gives the intervals [0, 1] and [1, 2]
• bisecting [-1, 1] gives the intervals [-1, 0] and [0, 1]
• bisecting an arbitrary interval ![[a,b]](https://tex.z-dn.net/?f=%5Ba%2Cb%5D) gives the intervals
 gives the intervals ![\left[a,\frac{a+b}2\right]](https://tex.z-dn.net/?f=%5Cleft%5Ba%2C%5Cfrac%7Ba%2Bb%7D2%5Cright%5D) and
 and ![\left[\frac{a+b}2,b\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cfrac%7Ba%2Bb%7D2%2Cb%5Cright%5D)
 
        
             
        
        
        
Answer:

I think the answer is 
no
no?
yes
yes
yes
no
Step-by-step explanation:
I'm not really sure if this is correct but from my textbook it says that the answer cannot have a math problem in it (E.g x = 1 + 2.3).
I am sorry if this is incorrect
If it is correct, can I have brainliest please?
