Find the angle that your line of sight to the sun makes when looking up at it
(angle of elevation), when a 24 ft tree casts a shadow that is 36 ft long. Round to
the nearest degree. *

34°

Step-by-step explanation:

Height of the tree=Perpendicular=24ft

Length of shadow=Base=36ft

Tan∅=Perpendicular/Base

Tan∅=24/36

Tan∅=2/3

∅=Tan-¹ (2/3)

∅=33.69°=34°

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 c
