Answer:
5 yr and 39 yr
Step-by-step explanation:
Let x = the age of the younger
 then 7x + 4 = the age of the older
Now x + 7x + 4 = 44
8x + 4 = 44
8x = 40
x = 5
7x + 4 = 7(5) + 4 =  35 + 4 = 39
Check:  5 + 39 = 44
 
        
             
        
        
        
Answer: Last Option

Step-by-step explanation:
In this case we have a uniform probability. In the graph the horizontal axis represents the possible values of the variable x and the vertical axis represents the probability P(x).
To calculate the probability that x is between 4.71 and 7.4 we calculate the area under the curve.
The horizontal length between 4.71 and 7.4 is:
 .
.
Then notice that the vertical length in this interval is 0.125.
Then the area of a rectangle is:

Where l is the length and w is the width.
In this case we have to:


So


 
        
             
        
        
        
It’s interval. It will be right.
        
             
        
        
        
Exp prob (red)   = 24 / 60  =  4 / 10   = 2/5
Theoretical prob (red)  = (1/2) 
Exp prob (blue)   =  14 / 60  =  7 / 30
Theoretical prob (blue)  = 1/6
Exp prob ( yellow)  =  22/ 60  = 11/30
Theoretical prob ( yellow)  =   2/6  =  1/3
