b) Determine appropriate parameters for the model type choosen.
c) Calculate the relative error of your model.
d) Use the model to predict the time at which the initial population number is increased by a factor of 2.

3.13) Suppose human population grows from 6.3 billion in 2000 to an ultimate population of 10.3 billion following the logistic curve. Assuming a growth rate of 1.5% in 2000, when would the population reach 9 billion? What would the population be in 2050?

Rate of Growth is: 300
a) Use your equation in part b(equations: P = 300t + 1750) to approximate how many years it will take the population to reach 7000.
b) Graph this function in MS Excel by plotting the points found in your chart in part a. Label your axes with time on the x-axis and population on the y-axis.

Assume the carrying capacity of Earth is 23 billion. Use the 1960s peak annual growth rate of 2.1% and population of 3 billion to predict the base growth rate and current growth rate with a logistic model. Assume a current population of 6.8 billion. How does the predicted growth rate compare to the actual growth rate of about

Find examples of countries for each populationgrowthmodel (rapid, slow, zero). What evidence can you find to support your choices? What problems/challenges/opportunities does each of these countries face in the next 10-20 years as a result of their particular class of growth?

Suppose that the country of less developed has a gross savings rate of 20%, a depreciation rate of 3%, and an incremental capital -output ratio (ICOR) of 2.5.
1- Using the Harrod -Domar (or AK) growthmodel, calculate the implied rate of growth of GNP per capita?
2- if the populationgrowth rate in less developed is 1.5% per

The U.S. Census Bureau International Database gives the population of the ten most- populated countries in the year 2000 and population predictions for 2050 for these countries: Chinahad 1.2 billion people in 2000 and is
predicted to have a population of 1.3 billion in 2050. The U.S. had a population of 284 million in 2000 with

In 1990, the population of Austin, Texas, was 494,290. During the next 10 years, the population increased by about 3% each year.
A. Write a model (equation) showing the population, P, in thousands of Austin t years after 1990.
B. What was the population in 2000? Show your work.
C. Estimate the year when the population

Populationgrowth in Ethiopia: In 2006, the estimated population in Ethiopia was 75 million people with a relative growth rate of 2.3%.
a. Write an equation that models the populationgrowth in Ethiopia, letting 2006 be year 0.
b. Based on the model, what is the expected population in Eithiopia (to the nearest million) in
