Firstly the equation would be y=7.7x+59
(A)The slope is 7.7 (B) and shows that there is a 7.7 charge per week the person attends. 
(A)The y intercept is 59 (B) and is the initial fee that the gym charges.
        
             
        
        
        
Answer:
Step-by-step explanation:
The square indicates that the total angle is 90 degrees so 
d+59=90
d=90-59
d=31 degrees
 
        
                    
             
        
        
        
Answer:
The probability that the selected adult has liver problems is 0.08
Step-by-step explanation:
In this question, from the data given, we want to calculate the probability that an adult selected at random has liver problems.
Let E(L) be the event that an adult has liver problems.
The probability is directly obtainable from the question and it is given as 8%
Thus, the probability that the selected adult has liver problems; P(L) = 8% = 8/100 = 0.08
 
        
             
        
        
        
Answer:
a. 1
Step-by-step explanation:
Replace 1 with x
2 ( 1 + 1 ) = 1 + 3
2 ( 2 ) = 1 + 3
4 = 1 + 3
4 = 4
