Each square below represents one whole. What percent is represented by the shaded area?

76%

There are 50 total squares and 38 are shaded.

38/50 =

76%

The answer to your question is 52

Step-by-step explanation:

Data

Percent of shaded area = ?

Process

1.- Count the numbers of squares in the first square

Number of squares = 5 x 5

                                 = 25

2.- Count the number of shaded squares in the second square

Number of squares = 13

3.- Calculate the percent of shaded squares using proportions

                    25 squares 100%

                      13 squares  x

                           x = (13 x 100) / 25

                           x = 1300 / 25

                           x = 52%      

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! )
