Answer:
The difference in population density between 2010 and 2018 is of 6.42 hab/MI²
Step-by-step explanation:
The population density is the number of habitants divided by the area.
Arizona:
Has an area of 113,998MI².
2010:
6,392,017 habitants, so the density was 6,392,017/113,998 = 56.07 hab/MI².
2018:
7,123,898 habitants, so the density was 7,123,898/113,998 = 62.49 hab/MI²
Difference:
62.49 - 56.07 = 6.42 hab/MI²
The difference in population density between 2010 and 2018 is of 6.42 hab/MI²
