Answer:
C 200
Step-by-step explanation:
It does not appear to be LINEAR so 
Start with :
pulse rate = y = 73e^kx  
sub in x = .7      when y = 155
155 = 73 e^(.7 * k) 
ln ( 155/73)  =  .7k 
.75296567  = .7k 
      k = 1.07567
for x = 0.9 :
pulse rate  =  y = 73 e^(1.07567 * .9)  = ~ 192      so I expect answer is 200
 
        
             
        
        
        
Answer:
90 shoppers have cookies or fruits as their favorite snack.
Step-by-step explanation:
First add 15% and 15% to get a total of 30% then multiply 300 by 30 to get 9000 and divide that by 100 to get your answer of 90.
 
        
                    
             
        
        
        
If the line is parallel, it has the same slope. So now just find the y intercept and put it into slope-intercept form
        
             
        
        
        
The answer is 7 because it goes 10th 100th and the thirty one is thousands
