type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.
the solution set of n2 - 14n = -45 is {
(separate the solutions with a comma)

the solution set of n2 - 14n = -45 is {5, 9}

Step-by-step explanation:

We have the following equation: n^2 - 14n = -45

Rearrange:

n^2 - 14n +45 = 0

Factorizing:

(n-9)(n-5) = 0

Therefore, the solution set of n2 - 14n = -45 is {5, 9}

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! )
