Find the area of sector AOB, in terms of π rounded to the nearest thousandth if necessary, and to the nearest hundredth of a square centimeter.

The area of sector AOB is

π ≈

cm2.

0.32π cm²

Or, 1.01 cm²

Step-by-step explanation:

AOB is a semi circle

(Sector with angle 180° at the centre)

Radius = 1.6/2 = 0.8

(180/360) × π × 0.8²

= 0.32π cm²

0r 0.32 × π = 1.005309649 cm²

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! )

the answer is 375 miles
