First answer gets brainliest on quiz !

jesse is sanding a circular wooden table that has a diameter of 6 ft. she can sand 5 square feet every hour.

at this rate, approximately how long will it take jesse to finish sanding the table?

use 3.14 for pi.

select from the drop-down menu to correctly complete the statement.
it will take jesse about hours to finish sanding the table.

a: 3.8

b: 5.7

c: 22.6

d: 30.0

! : d

Option B

Step-by-step explanation:

Step 1

Find the area of a circular wooden table

The area of a circle is equal to

we have

------> the radius is half the diameter

substitute

Step 2

we now that

Jesse can sand square feet every hour

so

by proportion

find how long will it take Jesse to finish sanding the table

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! )
