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\%

Total                  31

The volume of a solid gold statue can be approximated as 1000\text{ cm}^31000 cm 3 1000, space, c, m, start superscript, 3, end
SVETLANKA909090 [29]
The mass of the statue is 20,000 grams.

To find the density of an object, you divide the mass by the volume. Therefore, we can write the following equation. All we need to do is input our values and solve.

D = M  / V
20 = M / 1000
20,000 = m
