Answer:
The range for boys is 0-12 and the mean is 5.1
The range for girls is 2-8 and the mean is 5.3
Step-by-step explanation:
 
        
                    
             
        
        
        
The least common multiple of each pair of the polynomial (5y² - 80) and
 (y + 4) is equal to 5(y-4)(y+4).
As given in the question,
Given pair of the polynomial is (5y² - 80) and (y + 4)
Simplify the given polynomial using (a² -b²) = (a-b)(a +b)
(5y² - 80) = 5(y² -16)
⇒(5y² - 80) = 5(y² - 4²)
⇒(5y² - 80) = 5(y -4)(y + 4)
And  (y + 4) = (1) (y+4)
Least common multiple = 5(y-4)(y+ 4)
Therefore, the least common multiple of the given pair of the polynomial is 5(y -4)(y+ 4).
