Solution :
1). The cost of the formula is given as :
    $ 19,350 + $12 x
2). 95%  for the prediction is :
 for the prediction is :
     
      
       (rounding off)
    (rounding off)
3). r = 0.92
Therefore, 
That is 84.64 % of the variability in the moving cost is best explained by the number of moves.
 
        
             
        
        
        
Multiply 325326×(325325/2)=52,918,503,138 How it works:
know that 325325+1 is 325326, then 325324+2 is the same number, therefore you will get this number as many times as half of biggest number since you sum every last biggest number-1 with every last smallest number+1. so just multiply and you will get

4-7x=5
 +7x +7x
4= 12x
/12  /12
x= 4/12
x= 1/3
