The width of a rectangle is 6 km less than twice its length if the area is 140 square kilometers find the dimensions of the rectangle

L = 10 , W = 14

Step-by-step explanation:

Let represent the Length and represents the Width , then from the first statement , we have

That is :

The formula for finding the area of a rectangle is given as:

x Width

That is :

140 =

That is :

solving the quadratic equation , we have

or

Since the length can not be negative , therefore :

L = 10

Substitute L = 10 , to get W ,

W = 2L - 6

W = 20 - 6

W = 14

Therefore , the dimension is 10 x 14

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! )

hi! i think the answer is 1/2 : )
