I mean, telescopes were as good as they are now. If they landed on the near side, we could have seen the whole thing. Am I wrong?

Now it is your choice.......beleive it or not Nibiru will be visable by 2009 by telescopes then.........2010 it will be visable by the naked eye.
Is it just an odd mixup that the Mayan calender ends in 2012?Now some people say that it is it's own little solar system with a Brown Dwarf in the middle and Nibiru and an Earth sized object, maybe Nibiru's moon or something, which i do not beleive and you should'nt either.Buy i do not think NASA would take it this seriously if NASA built a what they call "Planet X Tracker".
I am not so possitivly acting to this because they also said it's coming in April 2003. The "Death Planet" is also another name for it. They say that 30Ft. giants as the bible refers to as the "Nephlim Giants" will come down and wipe out older men than children then women but men that are able to go in the military such as 16 yrs. - 30 yrs. old will be treated as the white treated blacks..........SLAVES FOR 500 YEARS!!!!!!!!!!!See what happens, LIFE IS A *****!Now your prolly thinkin how the **** are we goin to be slaves for 500 years?
I to thought the same thing but if you go back to mosses' time the earth's oxegen level was so high so then they lived sooo long. Now-a-days we loose a lot of it each year because we polute our air with cars and factories. So in about 30 years most peopl will live in Cnada because of global warming if we did not polute we would not have global warming.
They don't polute so don't have any thing like global warming they have very very high oxegen levels. Now the death planet is supposed to be the size of Jupiter.It's year is 3600 earth years and live to be nearly 10,000,000,000 earth years now we will really be slave for 500 of they're years. you wanna no take 3600 multiplied by 500=1,800,000,000 years nearly two-billion years!!!!!!!!
Now this planet is once again the size of Jupiter so when it comes around we will have pole shifts much too fast so it will be a LIVING HELL!!!Is what i mean by living hell is that we will have tsunamis 3 miles into the sky small twister, tornados, and hurricainens at a minimum of 300 mph!!!!!!!!!! Volcanoes will erupt left and right earthquakes magnitude 30 when the highest the earth has ever experienced was magnitude 9!!!!!!!!! Now before this happens Nephlim giants will take the slaves. Now the bible referrs to them as Nephlim Giants and they say gods such as Ra came from the death planet. Now idk if you've ever heard of "Noa's Flood" which was in the bible times they say was created by the Nephlim giants because they were so pissed off because the population was 1 billion now they come back 3600 years later.HAHa HOW ***** PISSED WILL THEY BE WHEN TODAY OUR CURRENT POPULATION IS 6 1/2 BILLION ROUGHLY PEOPLE HERE? Also, the symbols for this planet are serpants, dragons, and last a circle or sphere with wings or rings bacuase they say the the Death Planet has wings and Hell is located on this planet.
This is mostley Zecharia Sitchin. Now you can beleive what you want if u want more info then go to youtube.com and type in
"NIBIRU 2012 THE END?"
Now it's your choice..........either way it will happen maybe not in 2012 but it is coming just a little heads up!

We have been through this problem many times and can't quite get it; any help is appreciated.

Let T be triangle with verts (0,0) (1,0) and (1,2).
Suppose X,Y have joint pdf (5/2)(x^2)*y for x,y in T.

Find E[Y|X], E[Y^2|X] and (we can probably handle) Var[Y|X].

Again, thanks for any help!
