Question

If the area of Ohio remains the same, but had the same population density as Alaska , how many people would we expect to live in Ohio? Express your answer rounded to the nearest tenth of a million.

Answer 1

Remember that population density $Pd= \frac{population}{area}$.
First, lets calculate the population density of Alaska. IAs of 2016 the population of Alaska is 741894, and its area is 663268 sq mi; therefore, $Pd= \frac{741894}{663268}$= 1.12/sq mi.
Now, the area of Ohio is 44825 sq mi.
Second, lets replace the population density of Alaska and the Area of Ohio into our population density equation to get the new expected population of Ohio:
$1.12= \frac{population}{44825}$
$population=(1.12)(44825)$
$population=50204$

We can conclude that if Ohio had the same density population of Alaska, 50204 persons would live in Ohio. 

Answer 2

The population density of Alaska, per 2010 Census Bureau data, is 1.2 people per square mile. The land area of Ohio is known to be 44,825 square miles. If we then multiply these two figures, we would see the population of Ohio to only be 53,790 people, or 0.053 million. Rounding (up significantly) to the nearest tenth of a million, that would only be 0.1 million people.
