The perimeter of a rectangular atrium is 220 inches. the length of the atrium is four times the width. find the length and the width.

The length of the rectangular atrium is 88 inches and the width is 22 inches

Step-by-step explanation:

Let

x ----> the length of the rectangular atrium

y ----> the width of the rectangular atrium

we know that

The perimeter of the rectangular atrium is

so

Simplify

----> equation A

-----> equation B

substitute equation B in equation A and solve for y

Divide by 5 both sides

Find the value of x

therefore

The length of the rectangular atrium is 88 inches and the width is 22 inches

Width of atrium = 22 inches

Length of atrium = 88 inches.

Step-by-step explanation:

Given :  The length of the atrium is four times the width.

Let w be the width of atrium , then its length will be l= 4w.

Formula to find perimeter:-

Since, The perimeter of a rectangular atrium is 220 inches.

Then, we have

Width of atrium = 22 inches

Length of atrium = 4(22)=88 inches.

just put them in order

step-by-step explanation:

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )
