Rashid [163]

Answer:

The number of ways to select 37 people from 101 is, 5,397,234,129,638,871,133,346,507,775.

Step-by-step explanation:

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

${n\choose k}=\frac{n!}{k!\cdot (n-k)!}$

Compute the number of ways to select 37 people from 101 as follows:

${101\choose 37}=\frac{101!}{37!\cdot (101-37)!}$

$=\frac{101!}{37!\times 64!}\\\\=\frac{101\times 100\times 99\times....64!}{37!\times 64!}\\\\=5397234129638871133346507775$

Thus, the number of ways to select 37 people from 101 is, 5,397,234,129,638,871,133,346,507,775.

Four different towns in the same state grew in size due to a revitalization effort. The population of town A grew from 22,000 to

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).
