Answer:
77.77
Step-by-step explanation:
you subtract 16 (prediction) - 9 (actual) and divide it by the actual. 
 
        
                    
             
        
        
        
What you can use for this case is a function of the potential type.
 We have then
 y = a (b) ^ x
 Where we have:
 Walker starts the fund by depositing $ 5
 a = 5
 Each week the balance of the fund is twice the balance of the previous week:
 b = 2
 The function is:
 y = 5 (2) ^ x
 The number of weeks to reach $ 1280 is 8 weeks.
 Check:
 y = 5 (2) ^ 8
 y = 1280
 Answer:
 An equation can be used to find the number of weeks, x, after which the balance of the fund will reach $ 1,280 is:
 y = 5 (2) ^ x
 The number of weeks that it takes to reach the class goal is
 8 weeks
        
                    
             
        
        
        
Answer: I believe its 5/9
Step-by-step explanation:  
As you can see, the only fraction that doesn't equal 0.53, or the outlier, is 5/9 or 0.5556
 
        
             
        
        
        
Answer:
$600
Step-by-step explanation:
A = P(1 + rt)
P is the Principal amount of money to be invested at an Interest Rate R% per period for t Number of Time Periods.
 A= 5,000(1+ 0.08x1.5) = $5600
 
        
             
        
        
        
Complentary angles add to 90 degrees
a and b are complentary
a+b=90
a=7x+4
b=4x+9
so
7x+4+4x+9=90
combine like terms
11x+13=90
minus 13 both sides
11x=77
divide both sides by 11
x=7
m a =7x+4=7(7)+4=49+4=53
m b=4x+9=4(7)+9=28+9=37
angle a measures 53 degrees
angle b measures 37 degrees
