Answer:
47,000
Step-by-step explanation:
6,750 rounds up to 7,000
 
        
             
        
        
        
the question says that the samples included 100 people each, so it's just 100 multiplied by the amount of samples:
7×100=700
 
        
                    
             
        
        
        
So this is asking the cube root of -27 then squared.
Cube root of -27=-3
And -3^2=9
So I believe your answer is 9
