Question

A group of marine biologists estimates that if certain conservation measures are implemented, the population of an endangered species of whale will be  where N(t) denotes the population at the end of year t. Find the average population of the whales over the next 4 years.
A) 644 
B) 646 
C) 639 
D) 636

Quizplus · Accepted Answer

The average population over the next 4 years can be calculated as:

(N(1) + N(2) + N(3) + N(4))/4

where N(t) is given by:

N(t) = 11eaa8b1_da89_99af_b1b6_b75244ac0826_TB6026_11 = 646

Substituting the value of N(t) in the above formula, we get:

(N(1) + N(2) + N(3) + N(4))/4 = (646 + 646 + 646 + 646)/4 = 639

Therefore, the average population of the whales over the next 4 years is 639.

Hence, the best choice is C.
