anyone?

Let X be a random variable representing the number of times you need to roll (including the last roll) a fair six-sided dice until you get 4 consecutive 6's. Find E(X)? answer is 1554. I get confused with this, probability { X > n-5 }. I know that the last for throws must be 6's and the one...

show them how to take derivates and integrate. i wish i had learned this before taking Calc.

ok, i understand the site policy of not just giving the answer. but nothing else has worked. and i would acutally give credit to whoever gave me the answer. but I'm not, because this isn't homework. If you look at the link i gave you all, its from some calc tutorial website. so come on, just...

bummmmppppp

guys, i know the method, but like i said I'm getting some weird number here. please please do this for me. please just show every method mathematically. please i beg you. i need to get place this here. its for my calc II class. i have to move on to the next subject but i can't because this is...

C=-A sub "C" for "A": -4a + b + 8a + D=1----> D=-4a-b samething again:3a + 16c - 8d=29---->-8d=-29+13a samething again:-12a +3b +16b= 5 ===> im stuck someone help with all the steps, thankssss

b u m p!

man, I am getting some weired fraction as an answer for any variable i try to solve for... and i didnt even think algebra research existed, damn, that sucks i've wasted like 2 hours on this!

can u please just work out the problem. if i see how you do it i would get it. I'm this is actually for my Calc II class where I'm trying to do integration by partial fraction by i get the algebra wrong

http://tutorial.math.lamar.edu/AllBrowsers/2414/PartialFractions_files/eq0031M.gif i tried solving for C first, but i don't get the same answer if someone could just show me how to work it out i'd greatly appreciate it

I understand that a cyclohexane is usually more stable when the substituted group, like methyl, is in the equatorial axis. However, is it possble to determine the stability between, say, trans-1,2-dimethylcyclohexane and cis-1,3-dimethylcyclohexane. My guess is that the trans-1,2-dimethyl is...
