Question

the US Census found at the population per square mile in the state rose from 128.7 to 191.3 during the last 10 years. By how much did the population grow per square mile

Answer 1

62.6 per square mile.

Explanation:

The U.S. Census found at the population per square mile in the state rose from 128.7 to 191.3 during the last 10 years.

Population at initial year = 128.7

Population after 10 years = 191.3

Population grow per square mile = 191.3 - 128.7

= 62.6 per square mile.

Population grew 62.6 per square mile.

Answer 2

The population growth is 6.26 per square mile per year

Explanation:

We are given

he US Census found at the population per square mile in the state rose from 128.7 to 191.3 during the last 10 years

So,

Initial population =128.7

Final Population =191.3

Total time =10 years

now, we can find population grow per year

`=(final-initial)/(T)`

now, we can plug values

`=(191.3-128.7)/(10)`

`=6.26`

So,

The population growth is 6.26 per square mile per year
