Todd travels frequently for his business. For tax reasons, he wants to use up all of his remaining money in his business travel fund this year. He uses the function f (x) = x^2− 8 x + 16 to determine how many trips he must take to spend all of his remaining business travel funds. In this function, x represents the number of trips and f ( x ) is the amount of money left in his fund after the trips. The discriminant of this quadratic function tells us that his quadratic equation has real solutions

A. none

B. one

C. two

D. three

Step-by-step explanation:

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! )
