Answer:

4.77 cm correct to the nearest hundredth.

Step-by-step explanation:

Savatey [412]

Answer:

Town C.

Step-by-step explanation:

Average change of population with time for town A = \frac{24,500 - 22,000}{4} = \frac{2,500}{4} = 625

Average change of population with time for town B = \frac{34,770 - 31,200}{6} = \frac{3,570}{6} = 595

Average change of population with time for town C = \frac{22,000 - 18,000}{5} = \frac{4,000}{5} = 800

Average change of population with time for town D = \frac{34,100 - 32,000}{3} = \frac{2,100}{3} = 700

Town C had the greatest average change in population over time (800/yr).
