Answer:
The vertex is the point (-1,11). is a maximum
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to
where
(h,k) is the vertex
a is a coefficient
if a > 0 the parabola open upward and the vertex is a minimum
if a < 0 the parabola open downward and the vertex is a maximum
we have
Convert to vertex form
Complete the square
Factor the leading coefficient
Rewrite as perfect squares
The vertex is the point (-1,11)
The coefficient a=-5
so
a < 0 the parabola open downward and the vertex is a maximum
If A and B are independent, then P(A and B) = P(A) * P(B).
Then the probability that A occurs given that B occurs, for example, reduces to the probability that A occurs by itself:
So all you need to do is check that P(A|B) = P(A). If so, then A and B are independent. This is true only for the second case.
