Then from these strata a simple random sample of individuals are selected.
In this case the Biologist first divide the entire region of Red foxes into various groups. Then he samples 100 female foxes from each of these groups.

Step-by-step explanation:
<u>No calculus involved:</u>
The line, in slope-intercept form, has equation
, ie is always decreasing (easy to spot applying the definition)
Meanwhile,
is always increasing over its domain.
At no point the tangent will be decreasing.
<u>Let's use calculus</u>
We are to solve the equation
which has no real solutions.
