By this, I mean that both locations must be on Earth.

Ever wanted to be as far away from someone/something as possible? I was just wondering this today. Does anybody know?

We came up with an answer, but the teacher says we are wrong, but he hasn't got an answer for us yet
He said he will give us an answer tomorrow...

The question is...

Write a formula for the charge, C, to send telegrams at a cost of 75 cents for the first 10 words and 5 cents each for N additional words.

I say its "c = .75 + .05n"

And he is saying that what if the telegram is 8 words or has 14 words total
Then it would be .75 + .05(14)
But we are telling him it would be .75 for the first ten and then .05(4) for the four additional words
But he is saying that it is not clear enough
Can somebody please find the correct answer or explain a way for my answer to be correct?
Thanks

So, let's take a "fair" quarter. We would expect heads and tails to both come up 1/2 the time. Basic math says the chance of getting 10 heads in a row is (1/2)^10. I know this. BUT, are there any theories that say no, if p(A) = 0.5, in a fair system you will NEVER see more than X in a row, pragmatically?

I am not joking! It moved about 7 inches in my direction. I just stared at it until it stopped. The countertop is granite and it's level. I don't understand how that could have happened. I am not kidding!

If someone's going to get bitten, it's me. Do some people have a type of blood chemistry or temperature which makes them more likely to get bitten? Any biologists with a scientific explanation welcome, thanks.
