Circle W has diameter endpoints (- 10, 6) ) and (2, - 8) . What is the equation of the circle W in standard form?

The equation of circle W in standard form is + = 85

Step-by-step explanation:

Given the diameter endpoints: (-10,6) and (2, -8)

We know that the equation of circle is given by

+ =

where (x,y) is any point on the circle, (h,k) is center of the circle and r is radius of circle.

To find (h,k): the center is midpoint of diameter

Midpoint of diameter with end points (x1,y1) and (x2,y2) is given by

( ,  )

(  ,  )

(-4,-1)

Hence (h.k) is ( -4,-1)

Substituting values of (h.k) and (x.y) as (-4,-1) and (2,-8) respectively in equation of circle, we get

+=

= 85

Substituting the values of (h,k) and , we get the equation of circle as

+ = 85

Hence the equation of circle W in standard form is + = 85

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! )
