The formula that we would use is the probability of both over the probability of the rain only.
P[Wind and Rain ] / P [Rain] = 0.35 / 0.65 = 0.538 = 54%
The answer is A.
Answer:
false but Least common multiple (LCM) of 6 and 12 is 12.
You get everything you need from factoring the last expression:
The left side is a difference of squares, and we get another difference of squares upon factoring. We end up with

Circumference of a circle - derivation
This page describes how to derive the formula for the circumference of a circle.
Recall that the definition of pi (π) is the circumference c of any circle divided by its diameter d. Put as an equation, pi is defined as
π
=
c
d
Rearranging this to solve for c we get
c
=
π
d
The diameter of a circle is twice its radius, so substituting 2r for d
c
=
2
π
r
If you know the area
Recall that the area of a circle is given by
area
=
π
r
2
Solving this for r
r
2
=
a
π
So
r
=
√
a
π
The circumference c of a circle is
c
=
2
π
r
After graphing the lines, you can see that the solution is (4, -1)
