I got a 1/2. Which one did I get wrong? Please help

Step-by-step explanation:

Right away, because the scale factor of the dilation is 1/2, which is less than 1, the new surface area should be less than the original.  Simply multiply each side length by 1/2, then recalculate for surface area to get 4*4*6, or 96.

Hope it helps :) and let me know if you want me to elaborate.

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! )

what are the things "represented below"?

nobody can if you dont give the choices
