How can you decompose the composite figure to determine its area?
a) as a circle, three rectangles, and a triangle
b) as a circle, a trapezoid, and four triangles
c) as a semicircle, three rectangles, and a square
d) as a semicircle, a trapezoid, and two rectangles

D) As a semicircle, a trapezoid, and two rectangles.

Step-by-step explanation:

In order to find the area of the composite figure provided, it is necessary to descompose it.

Observe the image attached.

You can observe that it can descomposed as:

1- A semicircle, whose area can be calculated with this formula:

Where r is the radius.

2- A trapezoid,  whose area can be calculated with this formula:

Where h is the height, B is the larger base and b is the minor base.

3- Rectangle.

4- Rectangle.

The formula for calculate the area of a rectangle is:

Where l is the lenght and w is the width.

146 days

step-by-step explanation:

1. (365*2)/5 =

730/5 =

146 days

2. 365/5=

73*2   = 146

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! )
