3p – 2 = -89 what is the p

p= -29

Step-by-step explanation:

3p -2 = -89 (start off by getting rid of the constant)

     +2    +2

3p= -87 (Inverse operation)

/3     /3

p= -29

ALWAYS PLUG IN TO CHECK YOU ANSWER!!

3p – 2 = -89

3(-29) – 2 = -89

-87 -2 = -89

-89 = -89

Hope this helped! Have a good day!!

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! )

is only a line? i think so
