Answer:

A

Step-by-step explanation:

Khan gives you right answer and tells you what's wrong, but this site is for help so, all you need to do is use the destructive property.

12 x 2= 24 12 x 3 = 36 12 x -1 = -12

now you have the original expression, 24 + 36 - 12 (without the letters.)

Answer:

P (3 or fewer) =0.2650

Step-by-step explanation:

Mean = x` = 5

The Poisson distribution formula  is given by

P(X) = e-ˣ` x`ˣ/ x!

The mean is 5 and the X takes the values 0,1,2,and 3 which means 3 or fewer, so we add the probability of all the values of X to get the desired Value of X.

P(3 or fewer ) = e-⁵ (5)³/3!+  e-⁵ (5)²/2! +e-⁵ (5)/1!+e-⁵ (5)⁰/0!

Putting the Values

P (3 or fewer) = 0.006737 . 125 / 6 + 0.006737 . 25 / 2 +0.006737 . 5 / 1 + 0.006737 . 1 / 1

P (3 or fewer) = 0.140374 + 0.08422+ 0.03369 +0.006737

P (3 or fewer) =0.2650

Find the area of the circle with the given radius or diameter use pi equals 3.1 4 R is equal to six
marysya [2.9K]
<h2>Hello!</h2>

The answer is:

The area is equal to 113.04 units.

<h2>Why?</h2>

To find the area of the circle, we need to use the given information about the radius (6).

So, the area of a circle is given by the following formula:

A=\pi *r^{2}

Where,

\pi=3.14 (For This Case)\\r=radius

Substituting the given radius, we have:

A=3.14*(6)^{2}=3.14*36=113.04units

Have a nice day!
