Suppose you are managing 15 employees, and you need to form three teams to work on three different projects.

Assume that all employees will work on exactly one team. Also, each employee has the same qualifications/skills, so any employee can serve on any team.

How large is the sample space for all ways the three teams be chosen when the number of employees on each project are as follows:

6 on Team 1

4 on Team 2

5 on Team 3

Mmmk.
So my project is:
Which percent of worm castings versus store brought soil will make bean plants grow faster?
And I add more worm castings as I go.
Ex. 100% soil 0% worm castings, 25% worm castings 75% soil, 50% worm castings 50% soil, etc.
I know what my independent variable is; it's what I change so it would have to be the WORM CASTINGS.
But what is my dependent variable?

And what the hell is a Review of Literature?
And how do I write it?

HELP ME PLEASE!!!
Thanksss.
(:

I mean, it is obvious that it has happened many times! What would happen if one hit the moon and adjusted its orbit by like...just a few feet?

Would you want to see what the future is like? Or would you want to change something in the past? You can't choose both.

Is it really dangerous to swim when it is lightning or is this just a myth?

I know water conducts electricity but this doesn't make the lightning any more likely to strike a person in water. A person standing on the ground is just as likely to attract a lightning bolt. Why would the lightning care if your body is surrounded by water or air?

Lightning tends to strike tall objects so since water accumulates at the lowest points, wouldn't it be safer to stand in a lake than on top of a hill?
