Chapter , Problem 16(choose chapter or problem)
(a) The population of the world was 6.1 billion in 2000 and 6.9 billion in 2010. Find an exponential model for these data and use the model to predict the world population in the year 2020. (b) According to the model in part (a), when will the world population exceed 10 billion? (c) Use the data in part (a) to nd a logistic model for the population. Assume a carrying capacity of 20 billion. Then use the logistic model to predict the population in 2020. Compare with your prediction from the exponential model. (d) According to the logistic model, when will the world population exceed 10 billion? Compare with your prediction in part (b).
