Answer:
247.12 million
Step-by-step explanation:
Given:
In 1990, population=242 million
In 1999, population=244 million
estimated population in 2013=?
Estimated growth is calculated by:
P(t)= Po*e^(kt)
where Po is original population
k is growth rate
t is the time in year
Now putting the values of Po=242, P(t)=244, t=9 (t=1999-1990=9) we have:
244=242e^(9k)
(244/242)=e^(9k)
ln(244/242)=9k
k=1/9ln(244/242)
k=0.00091
Now Putting k=0.00091, Po=242, and t=23 (t=2013-1990=23) we have:
P(t)=242e^(23*0.00091)
P(t)=247.12 million
the population in 2013 estimated to be 247.12 million!
