which statement is true about figures abcd and a′b′c′d′? (1 point)

a polygon abcd has a at ordered pair 2, negative 2, b at 1, negative 4, c at 0 and negative 2, d at 1 and negative 1. a polygon a prime b prime c prime d prime has a prime at ordered pair negative 2, negative 2, b prime at ordered pair negative 1, negative 4, c prime at ordered pair 0, negative 2 and d prime at ordered pair negative 1, negative 1.

a) a′b′c′d′ is obtained by rotating abcd counterclockwise by 180 degrees about the origin and then reflecting it across.

b) a′b′c′d′ is obtained by translating abcd 2 units up and then reflecting it about the y-axis.

c) a′b′c′d′ is obtained by translating abcd 2 units up and then reflecting it about the x-axis.

d) a′b′c′d′ is obtained by rotating abcd counterclockwise by 180 degrees about the origin and then reflecting it across the y-axis.

D)

Step-by-step explanation:

We know for sure that it reflects about the y axis and answer choice D is one of the two who state that. And since when reflecting the y value stays the same you know choice B is incorrect. Therefore, the answer is answer choice D.

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! )
