When you're looking to simplfy a number, the best thing to do is to list all of the factors of that number;
21- 1,3,7
8- 1,2,4,8
The only common factor between these is one, and this is what they're currently in, therefore, it cannot be simplified.
Hope this helps :)
        
                    
             
        
        
        
Answer:
X = 600
Step-by-step explanation:
x-(0.0765x)=554.1
x-0.0765x=554.1
0.9235x=554.1
x=600

Answer:
a) E(y) = 0.8
b) The average subcharge is $165
Step-by-step explanation:
We are given the following distribution in the question:
y:           0        1        2         3
P(y):   0.50   0.25   0.20   0.05
a) E(y)

b) Expected value of subcharge
Subcharge = 

Expected value of subcharge = 

Thus, the average subcharge is $165
