Question 5 of 10 What is the slope-intercept equation of the line below?
O A. y = 2x-1
O B. y=-2x+1
O C. y=2x+1
O D. y=-2x - 1

the answer is d

Step-by-step explanation:

y=mx+b

m is slope. slope is rise over run. it goes down 2 and over 1. so it would be the fraction 2/1 which is 2 and since it is going down it is a negative. so neg 2.

b is the y intercept. which is where the line crosses the y axis. which is at -1

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! )
