Use the net to find the lateral area of the cylinder. Give your answer in terms of pi.

Zinaida [17]

Answer:

The correct answer option is 153 $\pi mm^2$ .

Step-by-step explanation:

We are given a cylinder with a radius of 4.5 mm and a height of 17 mm and we are to find the lateral area of this cylinder.

We know that the formula of the lateral area of a cylinder is given by:

Lateral area of cylinder = $2 \pi r h$

Substituting the given values in the formula to get:

Lateral Area = $2\pi *4.5*17$ = 153 $\pi mm^2$

Suppose that X is a geometric random variable with p=2/3 Solve for P (X=1 ∩ X ≥ 3)?

Tcecarenko [31]

$X$ can't simultaneously be equal to 1 and larger than 2, so the probability must be zero.

Did you mean to find the probability of the union? In that case, since the events are mutually exclusive, you would be able to write

$\mathbb P((X=1)\cap(X\ge3))=\mathbb P(X=1)+\mathbb P(X\ge3)$
$=\mathbb P(X=1)+1-\mathbb P(X$
$=\mathbb P(X=1)+1-\mathbb P(X\le2)$
$=1+f_X(1)+F_X(2)$

where $f_X(x)$ is the probability density function and $F_X(x)$ is the cumulative distribution function for the random variable $X$ .
