It's D, because the mean doesn't matter as much if it's only taken in a small variability. The mean was selected from 25 random pages in the book, that is why it is right. 
 
        
                    
             
        
        
        
Answer:
b) 1000x + 115
Step-by-step explanation:
C = 20y + 15
= 20(50x + 5) + 15
= 1000x + 100 + 15
= 1000x + 115
 
        
                    
             
        
        
        
Answer:
30 
Step-by-step explanation:
1/2 x (a+b) x h = area
1/2 x ( 40 + x ) x 50 =  1750 
1/2 (40 + x )= 1750/50 
20 + 1/2x = 35 
1/2 x = 35 - 20 
x = 15 x 2 
= 30 
I hope this is right :)
