How do I calculate the volume of 1x100000 infected parasites to give per 200ul/mouse and for 50 mice. The average number of uninfected is 8x1000000000.

I am sorry but this question doesn't make sense to me. I assume you have infected and uninfected parasites together in a solution. You have 10 ⁵infected parasites in how much solution???

:ugeek: How many ways can 8 guest be seated in a round table with 8 chairs

Hi Yaniees,
The first person can sit anywhere. You need someone seated in order to START the order (there is no beginning or end like when you put things in a row)
After that there is 7 places for the next person, 6 places for the next one etc
That is there are 7! permutations which is the same as 7P7

Here is my version of the magic number (choose the one that is best suited to your ability level)

Rules:
You have to use some or all of the numbers to make the magic number. You are not allowed to use any of the numbers twice. (Unless one was written twice in the first place)
You can use brackets, +, -, x, or divide and that is it.

EASIER ONE (not done yet)
3,5,2,4 and the magic number is 40

HARD ONE (Hopefully it is easier than Reiner-g's last one. I think that it is)
3 8 9 10 50 100 and the magic number is 583

Happy calculations.

2 2 5 7 17 20 and the magic number is 1994

Maybe we could have a little hint ? Please Reinout-g

Hint: 1994/2 = 997

WOW
Even with the hint it was really HARD
This is what i did (eventually)
5x7x20 = 700
2x7x20 = 280
added together this is 980
980+17=997
Now lets factorise 5x7x20 + 2x7x20 = 7x20(5+2)
So the final answer is

2x[7x20x(5+2)+17] = 1994

Good evening everyone,
It was really hectic today. The questions never stopped.
There were some great answers provided today by Bob, Rom, I like Serena, Princess Sophie and Guest. Thank you all.
Warped Tour Girl (who has been with us since our quieter days) Gave Rom and me a very nice thank you for our efforts.

Reinout-g gave some feedback regarding organizing our resources. At the moment I am starting to 'throw them' into onto one of the information threads below. They will need to be organised better than this eventually. Some things will need there own posts but I thought we could eventually, when it is organised properly, take a page each to use for our own selections. Obviously the individual will need to be responsible for his/her own page, since no-one else will have editing access. There is a free program called Gyazo which acts like the snipping tool accept the picture gets stored in the cloud and it has its own address that can be shared. Maybe we could make good use of this. My computing knowledge is quite poor. Maybe other people have better ideas.

That's it.
Goodnight all.
Melody.
Edit: Doesn't anyone know how people are including symbols such as integral signs and +- signs into the body of their posts?
I thought perhaps they are using the control key. Any thoughts?
