"There are three variables supplied: average birth rate per individual, average lifespan, and rate of population growth (which is specified as none). The supplied values for these variables are contradictory."

The birthrate is given as births/animal/decade. The deathrate is deaths/animal/decade.

birthrate = deathrate

What's contradictory?

Birth rate is stated as 5 per animal per decade. Death rate is one per animal per decade. Birthrate is not equal to death rate, even though a stable population would require it to be so.

This question cannot be answered as is:

What is the ratio of males to femals in the steady state population of 24,000?

Are we to assume that this discussion relates ONLY to females that equates to only 50% (12,000) of the poplulation or what?

Sheesh...stupid problems from even more stupid teachers.

The brithrate is 0.5 antelopes/year/antelope. The death rate is 0.1/year. The two cannot be equal if the population is stable.
