Solve for x. write the smaller solution first, and the larger solution second. (x - +1)=0

The product of the two is 0, so one of them have to equal 0 as any number multiplied by 0 is 0.

First solution: x - 4 = 0

If x - 4 = 0, then x = 4. So the first solution for x is 4.

Second Solution: -5x + 1 = 0

Solving...

-5x + 1 = 0

-5x = -1

x = -1/-5

x = 1/5 or 0.2

So x = 0.2 and 4

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! )

hi! i think the answer is 1/2 : )
