You want to estimate how many fish there are in a small pond. Let's suppose that you first capture n1=500 fish, tag them, and throw them back into the pond. After a couple of days you go back to the pond and capture n2=120 fish, of which k=30 are tagged. Estimate the number of fish in the pond. There are approximately Answer fish in the pond.
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
