What is the volume of the sphere below?

Sindrei [870]

Answer: Option C.

Step-by-step explanation:

The volume of a sphere can be calculated with this formula:

$V=\frac{4}{3}\pi r^3$

Where "r" is the radius.

You can observe in the figure that the value of the radius of this sphere is:

$r=4\ units$

Then you can substitute this radius into the formula $V=\frac{4}{3}\pi r^3$ .

Therefore, the volume of the sphere shown in the figure is:

$V=\frac{4}{3}\pi (4units)^3$

$V=\frac{256}{3}\pi \ units^3$

If events X and Y are independent, what must be true? Check all that apply. P(Y | X) = 0 P(X | Y) = 0 P(Y | X) = P(Y) P(Y | X) =

lana [24]

if events X and Y are independent, then for intersection we multiply the probability

P(Y∩X) = P(Y) * P(X)

We know that

$P(Y|X) =\frac{P(YintersectionX)}{P(X)}$

Now we replace P(Y) * P(X) for P(Y∩X)

$P(Y|X) =\frac{P(Y)*P(X)}{P(X)}$

Cancel out P(X)

So $P(Y|X) = P(Y)$

Like that

$P(X|Y) =\frac{P(XintersectionY)}{P(Y)}$

Now we replace P(X) * P(Y) for P(X∩Y)

$P(X|Y) =\frac{P(X)*P(Y)}{P(Y)}$

Cancel out P(Y)

So $P(X|Y) = P(X)$

P(Y | X) = P(Y) and P(X | Y) = P(X) are true
