Problema Solution
a countys population in 1990 was 37 million. In 1999 it was 40 million. Estimate the population in 2016 using the exponential growth formula. Round your answer to the nearest million.
Answer provided by our tutors
Let x be years since 1990
x=0, y=37
x=9, y=40
So the regression equation is y = 37e^(0.00866x)
When x=26, y = 37e^(0.00866*26) = 46
So the population in 2016 is 46 million
