To gather information about the elk population, biologist marked 75 elk. later, they flew over the region and counted 250 elk, of which 15 were marked. what is the best estimate for the elk population?

It would be 0 at least it should be

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.

The answer is d $21.65 i got that on a test in school before and got an a+ it should be d
