17. Which of the following trigonometric functions can be described as a reciprocal trig function? O A. sin(e)
O B. sin-1(0)
O C. arctan(e)
O D. sec(0)

Step-by-step explanation:

Reciprocal trig functions are opposite or mirror of the normal trig functions. The normal trig functions are as follows:

Sine = opposite side/hypotenuse

Cosine = adjacent side/hypotenuse

Tangent = opposite side/adjacent side

The reciprocals of the above trig ratios would be

Cosecant = hypotenuse/opposite side

Secant = hypotenuse/adjacent side

Cotangent = adjacent side/opposite side

Therefore, looking at the given options, the trigonometric function that can be described as a reciprocal trig function is

D. sec(0)

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! )
