Make a frequency distribution and find the relative frequencies for the following number set. Round the relative frequency to th

Pani-rosa [81]

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 $\frac{1}{31} \times 100 =3.2\%$

21 4 $\frac{4}{31} \times 100 =12.9\%$

22 2 $\frac{2}{31} \times 100 =6.5\%$

23 4 $\frac{4}{31} \times 100 =12.9\%$

24 3 $\frac{3}{31} \times 100 =9.7\%$

25 2 $\frac{2}{31} \times 100 =6.5\%$

26 3 $\frac{3}{31} \times 100 =9.7\%$

27 5 $\frac{5}{31} \times 100 =16.1\%$

28 3 $\frac{3}{31} \times 100 =9.7\%$

29 4 $\frac{4}{31} \times 100 =12.9\%$

3x - 43 = 8
Shift the - 43 to the other side and change it to +
3x = 8 + 43
3x = 51
Isolate x by shifting 3 to the other side, dividing 51 by 3.
X = 51 / 3
X = 17
