Your friend claims that he has ESP. In order to prove his claim to you, he is going to have your write the names of ten of your friends on slips of paper and put one name into each of 10 sealed envelopes. You will invite the 10 friends to your house and your friend with ESP will distribute the envelopes using his ESP powers.

Here is the question: How many people have to receive their own name before you believe that your friend has ESP and isn't just randomly giving out the envelopes?

To answer the question you will first need to simulate randomly giving envelopes with names to 10 people to see what the distribution of correct names under random distribution looks like. You must do as many simulations as you need to be sure about the distribution. You must also be clear about how you did the simulation and what the results were.

Next you will have to choose an alpha level for your test of ESP. How many of your friends must get their own names in the envelope before your ESP friend has performed that much better than random?

Hi, I need help with this math problem, i would understand it, but the situations are different rather than same in this rate time and total problem, so it has me confused.

The fill pipe for a tank can fill the tank in 4 h, and the drain pipe can drain the tank in 2h. If both pipes are accidentally opened, how long will it takes to empty a half-filled tank?

What has me confused here is the filling/draining situation, and the thing about a half filled tank, so if you could please explain them, that would be nice... ^-^

The ordering and transportation cost C of components used in manufacturing process is approximated by

C(x)= 10 (1/x + x/(x+3) )
where C is measured in thousands of dollars and x is the order size in hundreds

A.) Verfiy that C(3)=C(6)
B.) According to Rolle's Theorem, the rate of change of cost must be 0 for some order size in the interval [3/6] Find this order size in hundreds

It's for my AP Calc class, of course steps would be FANSTASTIC so I could figure out how to do this on my own but I'd more than happy with a step or two. Thanks

ithis is not for me, im doing it for my cousin. The answer i got is 67.5 minutes. i just want some confirmation if this is correct.

question:
A fully charged cell phone can work in a standby position (you don’t talk on the phone) for 72 hours, or we can talk continually for 3 hours on it, and then we have to recharge it again. This cell phone, after it was fully charged, was on standby for 27 hours and then the owner conducted a 45 min. conversation. How many more minutes could we still talk on this phone?

p.s. ill post how i got my solution later if this question is bugging you and you want to know how i got 67.5 minutes
