what is the perimeter of rectangle jklm?
32 units
44 units
56 units
64 units

Third option.

Step-by-step explanation:

The missing figure is attached.

The perimeter of a rectangle can be calculated with:

Where "l" is the length and "w" is the width.

We can see that the width of this rectangle is:

So, we need to find the lenght.

Let be P the point  of intersection of the diagonals.

The diagonals of a rectangle are equal.

Since:

We know that, by definition:

Then, we can find the lenght of the rectangle by using the Pythagorean Theorem:

We can identify that:

Then, subsituting values and solving for "LM", we get:

Substituting values into the formula for calculate the perimeter, we get:

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! )

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
