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

Following from greatest to least 5 * 10 ^ 3 3.2 * 10 ^ 8 1.2 * 10 ^ 8 7 * 10 ^ 5

Zina [86]

Answer:

3.2*10^8>1.2*10^8>7*10^5>5*10^3

Step-by-step explanation:

5*10^3 = 5000

3.2*10^8=320000000

1.2*10^8=120000000

7*10^5=700000

320000000>120000000>700000>5000

therefor

3.2*10^8>1.2*10^8>7*10^5>5*10^3
