The regression equation is in the form y = mx+b where m = 938 is the slope
The slope of 938 means that each year the tuition is increasing by roughly $938. 
The answer is choice C.
        
             
        
        
        
   Between two rational numbers there are an infinite number of irrational numbers.
Example:
 
 
        
             
        
        
        
10/3. To find this answer you have to either multiply or divide by a specific number. You choose the number that goes into each of them. In this case I divided by 2 to both the top and bottom number. When I did this I got the answer of 10/3 
        
                    
             
        
        
        
Volume of a spehere=(4/3)πr³
Data:
diameter=3.5 in
π=3.14
1)we calculate the radius:
r=diameter/2=3.5 in / 2=1.75 in
2) we calculate the volume of this sphere:
volume=(4/3)*3.14*(1.75 in)³=22.4379...in³≈22.44 in³.
Answer: 22.44 in³
