The Lagrangian is

It has critical points where the first order derivatives vanish:



From the first two equations we get

Then

At these critical points, we have
(maximum)
(minimum)
Answer:
P( not win) = 2/ (n+2)
Step-by-step explanation:
There are n+2 total possibilities
There are n winners
not win = n+2 - n = 2
P( not win) = not win / total
= 2/ n+2
Answer:
i think A. because she is 4/2
Perpendicular, slope is reciprocal and opposite
so answer is C. -7
