Answer:
The median of the data set:
6, 15, 30, 45, 47, 49
The middle numbers are 30 and 45 so
You have to do 30 + 45
= 75
Then do 75 ÷ 2
= 37.5
The mean of the data set:
47, 15, 6, 49, 45, 30 (add them all)
= 192
Then divide 192 by 6 (because there are 6 numbers)
192 ÷ 6
= 32
So the median is 37.5 and the mean is 32.

<h3>What is a percentage?</h3>
A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given, the population in 2020 is 49992.
40 percentage of population
= 40 % of 49992
= 40 x 49992/100
= 19996.8
Now the population in 1982
= population in 2020 - 40% of population in 1982
= 49992 - 19996.8
= 29995.2
Therefore the population in 1982 is 29995.2.

Ratio: 72 to 126
can be turned into a fraction 72/126
we then simplify the fraction 72/126
72 ÷ 2 = 36
126 ÷ 2 = 63
36 ÷ 3 = 12
63 ÷ 3 = 21
72/126 ⇒ 36/63 ⇒ 12/21
ratio of 72 to 126 is 12 to 21.
72/126 = 0.5714
12/21 = 0.5714
