To estimate the number of lizards in a certain region, Sean traps 36 lizards and marks them. He releases these lizards and then later catches 200, 16 of which are marked. What is the BEST estimate for the lizard population?

A) 400
B) 425
C) 450
D) 475

475

Step-by-step explanation:

i divided the two numbers and got 556 so your estimate should be 475

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
