Make a frequency distribution and find the relative frequencies for the following number set. round the relative frequency to the nearest tenth of a percent. some of the answers will be used more than once and some may not be used. 10, 21, 21, 21, 21, 22, 22, 23, 23, 23, 23, 24, 24, 24, 25, 25, 26, 26, 26, 27, 27, 27, 27, 27, 28, 28, 28, 29, 29, 29, 29 number frequency relative frequency 20 % 21 % % 24 % 25 % % 27 % 28 % 29 %

Solution: We have to find the Frequency and Relative frequency of the given data:

Frequency is the number of times a number occurs.

Relative Frequency is the number of times a number occurs divided by the total number of items.

Therefore, the frequency and relative frequency are calculated as below:

Number       Frequency          Relative Frequency

20                       1                    

21                        4                    

22                       2                    

23                       4                    

24                       3                    

25                       2                    

26                       3                    

27                       5                    

28                       3                    

29                       4                    

Total                  31

i believe the answer is the polygon, heptagon.

not sure but it may be b, as i said i'm not sure.
