The following table shows UN data from 1975 and projections to 2050 of the size of a country\'s labor pool (ages 15-59) Complete parts(a) through (d) below Graph the model and the data on the same axes, and comment on the it. The window is(0, 80, 5) by(0, 1000, 100).choose the correct answer below. Look at the graph in the previous step. Notice that the model is a good it. Use the model to predict the size of the labor pool in 2028. The size of the labor pool is about 1010 million (round the nearest integer as needed) According to the model, When is the number in the labor pool project to be at a maximum? What is the maximum? The maximum will occur in the year (round down to the nearest year) The maximum is about million (Round to the nearest integer as needed.)

Solution

If we analyse the trend in data we find first labour pool increases continously

upto year 2015-2020 after that it contiously decreases, only in year 2045 it increases to 800

So, on the graph this point (2045 , 800) woul d not lie on the line of best fit

so, we get options and A and B

Option A is correct because graph starts from x=0 and y = 470

in year 2028 , labour pool can be found by avg of labour poll between years 2025 and 2030

= (885 +840)/2 = 862.5 = 863 million

Maxium labour poll occurs in year 2015

It is about 910 million
