Answer:

≈ 3.22% increase

≈ 9878813

≈ 4.19% decrease

Step-by-step explanation:

1. Population change from 53,594,378 to 55,317,240

Population has grown as number increased over time

Change%= (55,317,240- 53,594,378)/53,594,378*100% ≈ 3.22%

2. Population change from 9,938,444 by 0.6% drop

Population in 2010= 9,938,444*(100-0.6)/100 ≈ 9878813

3. Population change from 219,773 to 210,565

Population shrink indicated as number decreased over time

Change%= (219,773- 210,565)/219,773*100% ≈ 4.19%

Answer:

Step-by-step explanation:

  1. The population in the Northeast was 53,594,378 people in 2000 and 55,317,240 people in 2010. By about what percent did the population change? Did the population grow or shrink?  C = 100*(55,317,240 - 53,594,378) / 53,594,378 = 3.2%. This is positive, so the population grew.

2. 0.6 / 100 = 0.006  

Then, multiply the number of people living in Michigan in 2000 by the number of people decreased (the percentage decrease) in 2010

9,938,444 x 0.006 = 59630.664

Last, subtract the percentage decrease by the original population in 2000

9,938,444 – 59630.664 = 9,878,813

In 2010 the approximate population in Michigan was about 9,878,813 (to the nearest whole person)

3. Dividing 219,773 by the difference in the population between 2000 & 2010 which is 9,208  = 23.86762%
