Answer:
The cumulative frequency plot is also attached below.
Step-by-step explanation:
The data provided is as follows:
Age Group	Frequency
    0 - 9             34.9
   10 - 19             35.7
 20 - 29             36.8
 30 - 39             38.1
 40 - 49             37.8
 50 - 59             37.8
 60 - 69             34.5
 70 - 79             27.2
 80 - 89             18.8
 90 - 99               7.7
 100 - 109       1.7
Consider the Excel output attached.
The cumulative frequency are computed in the Excel sheet.
The cumulative frequency plot is also attached below.
From the cumulative frequency plot it can be seen that in the future most people will belong to a higher age group rather then the lower ones.
 
        
             
        
        
        
E: 36 because the total degrees of a parallelogram is 360 and opposite angles of parallelogram’s are equal so the angles diagonal from the given ones are the same. So the corners are 3x, 2x, 3x, 2x. In total that is 10x. 360/10 = 36
