(15 points) Please help! 2 pre-algebra questions! Will mark brainliest

Step-by-step explanation:

1. slope=-3/2-3 is at the top,2 is at the bottom

y intercept=4-The y intercepts or goes past at 4,

equation=y=-3/2+4-We put it all together and we get y=-3/2+4!

2. slope=-3/2-It starts at 3 again,and ends at two again.

y intercept=0-The y touches the line at 0,or the middle

equation=y=-3/2-y equals the slope and we subtract y.

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! )
