We can divide it like this: o | o|  o | o o

We have 5 apples and 3 dividers.

We then use the stars and bars formula. So we have (5+3)!/5!3!= 8C3=56 ways.

I am lol...

you're welcome!

Do either 9C4 or 9C5 to get 3024.

you're welcome!

Look carefully, if that side were 5 then the side AB should be 4, not $\sqrt{5}$. How you should solve this:

Divide ABCD in half diagonally. We have two triangles now. We apply the pythagorean theorem to triangle ABC. Then AC is $\sqrt{30}$. Now we know that for triangle ACD, that AC is $\sqrt{30}$ and DC is 4. Apply the pythagoren theorem again to find that AD is $\sqrt{14}$.

Each day has 24 hours so in 3 days there are 72 hours. To calculate the number of peope per hour we divide 2000/72=27 7/9 --> 28.

You're welcome :)

Well because it's just a regular coordinate plane...find 3 on the x axis then go up to find the y point on the line that meets with x=3.

E(3) is 5.
