Which equation is true?

a. 10 horsepower < 5,000 watts

b. 1,000 watt > 1 horsepower

c. 1,000 horsepower > 1 watt

d. 1,000 watt = 100 horsepower

The correct options are B and C

Step-by-step explanation:

To solve this problem, we can easily convert everything to the same units

1 horse power  = 745,7 watts

So,

A. 10 horsepower < 5,000 Watts

    7457 Watts < 5,000 Watts

  (Not true)

B. 1,000 watt > 1 horsepower

     1,000 W > 745.7 W

(TRUE)

C. 1,000 horsepower > 1 watt

    745700 W > 1 W  

(TRUE)

D. 1,000 Watt = 100 horsepower

1000 W =  74570 W

  (Not true)

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! )
