In the diagram shown points A, B, C, D, and E lie on circle M. Point P is on the exterior or circle M and secants PCD and PBE drawn. It is known that m

(a) Determine the measure of BC

(b) Determine the measure of

The measure of  

The measure of

Step-by-step explanation:

The correct question  is added in the diagram below.

From the diagram;

Given that:

∠A = 55°

∠P =38°

a) it is clear and obvious that ∠P  is formed at the exterior of the circle; so:

b)

∴       (rule: chord intersecting inside the circle)

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! )
