Hi there! 
Your question: 
Sales fall from 300 per week to 270 per week what's the percentage change?
My answer:
The formula for calculating percent change is as follows: 
[(y2 - y1)/y1]*100=your percent change 
y2= first value 
y1=second value 
Plug the numbers in: 
[(300-270)/300]*100
[30/300]*100
0.1*100
10 
Therefore, the percent change is 10%
Hope this helps! Let me know if it's incorrect so I can fix it:)

Answer:
   g(x) = 3x^2 -2
Step-by-step explanation:
Reflection in the y-axis replaces x with -x.
   g(x) = f(-x) = 3(-x)^2 -2
   g(x) = 3x^2 -2
_____
The given function is symmetrical about the y-axis, so its reflection is itself.
 
        
             
        
        
        
Step-by-step explanation:
You didn't give the box plot, but to obtain the percentage of people between 20 and 37 years old, first of all, find the total number of people, T. Next, find the total number of people between 20 and 37 years old, t. 
Then the percentage we want to find is:
P = T/t × 100
 
        
             
        
        
        
300 x 0.02 x 5 = 30
