When raised to the third power, it is the number times itself three times. 
-2(-2) = 4
4(-2) = -8
        
                    
             
        
        
        
Answer:
therefore reece'sis 16 years old
Step-by-step explanation:
18+p=34
p+18-18=34-18
p=16
 
        
             
        
        
        
That is the slope
rise/run
we see we have (2/5,1/2)
rise is y, run is x
(x,y)
((1/2)/(2/5)=(1/2)(2/5)=2/10=1/5
unit rate is y=(1/5)x
        
             
        
        
        
Answer:

Answer:       A                 B
Group 1     0.25          0.75
Group 2    0.44          0.56
Step-by-step explanation:
Since we have given that 
Number of people of A in group 1 = 15
Number of people of B in group 1 = 45
Total number of people in group 1 is given by

Relative frequency of people of A in Group 1 is given by

Relative frequency of people of B in Group 1 is given by

Similarly, Number of people of A in group 2 = 20
Number of people of B in group 2 = 25
 Total number of people in group 2 is given by

Relative frequency of people of A in Group 2 is given by

Relative frequency of people of B in Group 2 is given by

Hence,        A                 B
Group 1     0.25          0.75
Group 2    0.44          0.56
