Have scientists even given theories on this one? If it goes on forever than every possible combination that can physically come true, must come true, so there'd be a me somewhere typing this too and then another me typing this in a slightly different variation and then so many combos its not worth mentioning. Granted it seems so huge that a great deal of possibilities must be coming true at some point anyway. If the universe stops how is that possible? Does it bug anyone else?

is it worth my effort to document a series of events that happened to me at our local medical center today and ask for meeting with Administrator to dicuss same ?
Should I also contact my insurance company BC/BS and give them this info ? Not talking a lawsuit here-just want to file a formal complaint. Know for some states you can check ratings of hospitals, do not know about this one tho..not first problem, has been drug mistakes with family members xxx,incorrect diagnosis xx horrendous problems with their insurance billing , etc. How is best way to go on up the "food chain"?
This is the only "full service" ER and hospital within 75+ miles and has local nickname of Hospital Hell and many locals have a horror story to tell ! Have standing order `s with Life Flight to stabilize family members , then get us the hell to OKC ! Suggestions ???

"Two blocks are on a frictionless, level surface. They are in contact, but are not connected. Block 1 is on the left, and has a mass of 6.6 kg; block 2 has a mass of 4.2 kg. A constant force of 27 N is applied to block 1, parallel to the level surface. What is the magnitude of the force that block 1 exerts on block 2?" I solved first it's acceleration which is 4.09 m/s^2. Then I solved the Force, F=ma, F=(6.7kg)(4.09m/s^2)=27N. So the magnitude is 27. What did I make mistake? the answer says incorrect. Can anybody know this? please explain to me. Thanks.

What do you mentally see when you eg. add numbers in your head?

Usually, it's just unconscious..but sometimes it will be like eg. 16 + 25 Then the 16 kind of melts onto the 25 and I get the answer. ..anything u picture ...



Also, when you're doing eg. equations mentally ,
and you "see" the solution, what is this like ? Can you describe what you see in your head ...are the numbers/variables just moving around and falling into place

1) Using a graphing utility to zoom in on the maximum point of the revenue function p=40-(5x^2). Use a setting of (1.62 >= x >= 1.65) and (43.5 >= x >= 43.6). Use the trace feature to improve the accuracy of the apporximation obtained in the example. Do you think this improved accuracy is appropiate in the context of this particular problem? Does it change the price?
2) This problem is comparing to a graph of p=40-(5x^2) with points (0,40) and ((sqrt8), 0).

I believe that 1) graph is inappropiate comparing to 2) because 2) deals with maximum revenue more...im not sure how to explain this though. When i graph the two graphs 1) gives me a different trace than 2). I hope that you understand what im trying to say. Need help with this as much as possible. thanks

Two heterozygous parents for albinism. If they have four children, what is the probability of them having 3 normal children and one albino?

For people without biological knowledge, the probability of having a normal child will be 3/4, the probability of having an albino child is 1/4. The answer to this question is 27/64, which happens to be (3/4)^3, or also (3/4)^3(1/4) x 4C3, but honestly i have no idea what is the correct way to think about or get to the answer, i just had the answer and noticed those two ways to get to it. please explain work, thank you
