Answer:
The mean age of the frequency distribution for the ages of the residents of a town is 43 years.
Step-by-step explanation:
We are given with the following frequency distribution below;
  
      Age                      Frequency (f)               X                    
      0 - 9                            30                         4.5                   135
     10 - 19                           32                        14.5                  464
     20 - 29                         12                         24.5                 294
     30 - 39                         20                        34.5                 690
     40 - 49                         25                        44.5                1112.5
     50 - 59                         53                        54.5                2888.5
     60 - 69                         49                        64.5                3160.5
     70 - 79                          13                         74.5                968.5
     80 - 89                  <u>        8        </u>                  84.5         <u>        676        </u>
     Total                      <u>      242      </u>                                  <u>      10389      </u> 
Now, the mean of the frequency distribution is given by the following formula;
                           Mean =   
 
                                      =   = 42.9 ≈ 43 approx.
  = 42.9 ≈ 43 approx.
Hence, the mean age of the frequency distribution for the ages of the residents of a town is 43 years.
 
        
                    
             
        
        
        
That would be B, C and E.
A and D could be a rhombus.
