Question: Dependency ratio the share of the world population that is over 60 years of age compared to the rest of the working population in the world is of concern to economists. An increasing dependency ratio means that there will be fewer workers to support an aging population. The dependency ratio over the next century is forecast to be
R(t) = 0.00731t4 - 0.174t3 + 1.528t2 + 0.48t + 19.3 (0 ≤ t ≤ 10)
In year t, where t is measured in decades with t = 0 corresponding to 2000.
A. Show that the dependency ratio will be increasing at the fastest pace around 2052. Hint: use the quadratic formula.
B. What will the dependency ratio be at that time?
An investment is expected to yield a return of 14% if economic conditions remain healthy, or improve. If a downturn occurs the expected return is just 4%.
Let A = {1, 2, 3, 4, 5, 6,12} and define the relation R on A by m R n iff m|n. Show that this relation is a partial ordering relation. Draw its Hasse diagram.
