(20 points to best answer) complete the two-column the proof by writing the appropriate reason for each statement.

Please find the attached file.

Step-by-step explanation:

We have been provided a diagram and asked to complete two-column proof.

We are given that line segment JL is congruent to line segment KM. By definition of congruence

By segment addition postulate and .

After substituting JK+KL and KL+LM in our equation we will get .

Subtraction property of equality states that we can subtract same number from both sides of an equation. Subtracting KL from both sides of equation we will get .

Therefore, by definition of congruence line segment JK is congruent to Line segment LM.  

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! )
