Suppose that the number of newborns (N) in an insect population can be predicted from the number of adult insects (I) according to the following equation, where r and b are variables related to the rates of population growth: N=rI-bI2. Calculate N if r=1.5, b=0.0015, and I=500. Rounding to the nearest whole number, N equals which of the following?

Suppose that the number of newborns (N) in an insect population can be predicted from the number of adult insects (I) according to the following equation, where r and b are variables related to the rates of population growth: N=rI-bI2. Calculate N if r=1.5, b=0.0015, and I=500. Rounding to the nearest whole number, N equals which of the following?

N equals to 749 newborn insects.

Explanation:

We have the following to calculate the population of newborn insects.

N = rl - bl2

In this equation we need to replace the values we know that are:

l = 500

r = 1.5

b = 0.0015

Whn we replace the values we have:

N = (1.5) (500) - (0.0015) (500) (2) Now we just do the operations

N = 750 - (0.0015) (1000)

N = 750 - 1.5

N = 748.5 When we roung the nearest whole number we get

N = 749

There were 749 new born insects that are represented by N.
