Answer:
40
Step-by-step explanation:
The frequency column gives the number of houses in the sample, then
number of houses = 5 + 11 + 23 + 1 = 40
 
        
             
        
        
        
21 and -4, because -4x21 = -84, and 21+-4 (– 4) = 17
        
             
        
        
        
The last two (multiplying and dividing by a negative number on both sides) are the answer. Good luck and have a nice day!
