00:01
So first of all we have been given a line table.
00:04
So the age class is denoted as x.
00:11
The values are 0, 1, 2 and 3 followed by which we are given the number alive which is denoted by nx.
00:29
The values have been given as 82, 42, 25 and 70.
00:40
We have been asked to find out lx.
00:43
What is lx? so lx is basically the proportion of individuals who are surviving to each age class with respect to the initial number of individuals.
01:25
The formula to calculate lx is very easy.
01:30
It is lx is equal to nx by n0.
01:36
What does nx denote? nx denotes the given age class.
01:40
And what does n0 denote? n0 denotes the 0 age class.
01:48
The number alive in the 0 age class.
01:53
Nx in 0 age class.
01:56
That is denoted by n0...
