Question

Suppose a certain country's population has constant relative birth and death rates of 97 births per thousand people per year and 47 deaths per thousand people per year respectively. Assume also that approximately 30000 people emigrate (leave) from the country every year. Which of the following equations best models the population P = P(t) of the country, where t is in years? (see attachment)

Answer 1

It is easy. List the given items for me @needhlp

Answer 2

97 birth per thousand people per year and 47 deaths per thousand people per year

Answer 3

Just make sure that you convert the birth rate and death into decimal form

Answer 4

30000 leave ever year

Answer 5

first u should be able to write the expression for population in terms of time t.now population after t years is determined by the number of births -no.of deaths -no. of emigrants.now try to write the expression for pop

Answer 6

Make sure you convert birth rate, death rate into decimal
Now total rate of population of growth would be = birth rate- death rate.
This is for one year.

For t years it would be (birth rate- death rate)(t)

Now if 30000 people are leaving each year, then will population will ??

Answer 7

this is how u do it
97/10000 births every year,so no. of births in t years=(97/1000)*t

Answer 8

proceed in similar manner

Answer 9

honestly, I just want the answer since im taking this test right now.

Answer 10

honestly, nobody is willing to give you the answer unless you are willing to learn :(

Answer 11
