Aquadratic equation is shown below: x2 + 5x + 4 = 0 part a: describe the solution(s) to the equation by just determining radicand. show your work. (3 points) part b: solve 4x2 -12x + 5 = 0 using an appropriate method. show the steps of your work, and explain why you chose the method used. (4 points) part c: solve 2x2 -10x + 3 = 0 by using a method different from the one you used in part b. show the steps of your work. (3 points)

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! )
