Answer:
P(B|A)=y
Step-by-step explanation:
The complete question is shown in the attachment.
If the events, A and B are independent, then
P(A and B) = P(A)×P(B)
But from the question:
P(A)=x and P(B)=y
This implies that:
P(A and B) = xy
Also, the conditional probabilities are:
P(A\B)=P(A)=x
P(B\A)=P(B)=y
Therefore the correct answer is A
Answer:
y=-(x+1)(x-1)²(x-3)² = -x⁵ + 7x⁴ -14x³+2x² + 15x -9

Answer:
Step-by-step explanation:
basically, you have to look at the inequality. it is the same all around. so if the inequality has less than or equal too, or greater than or equal too, you need to have a thick solid line representing your function. if it is just less than or greater than, use a dotted line. to determine whether the shading goes above or below, you look at the in equality. greater than is above, and less than is below
We know for our problem that the zeroes of our quadratic equation are
and
, which means that the solutions for our equation are
and
. We are going to use those solutions to express our quadratic equation in the form
; to do that we will use the <span>zero factor property in reverse:
</span>
<span>
</span>
<span>
Now, we can multiply the left sides of our equations:
</span>
<span>= </span>
=
=
Now that we have our quadratic in the form
, we can infer that
and
; therefore, we can conclude that
.
