Explain. I know how to get population densities, but I have no clue how to make them the same. Can you show me how?
Date: 03/17/2002 at 21:43:49 From: Doctor Twe Subject: Re: Population densities Hi Hannah - thanks for writing to Dr. Math. The trick here is to first figure out what that equal population density is. We have a total of 3,275,000 + 476,000 = 3,751,000 people living in a total of 4,845 + 97,105 = 101,950 square miles. If the people were distributed evenly across both states, what would that population density be? Then how many people would live in Connecticut and how many would live in Wyoming? Finally, how many would have to move to make that happen? I hope this helps. If you have any more questions, write back. - Doctor TWE, The Math Forum http://mathforum.org/dr.math/
