a high speed dispensing machin fills boxes of laundry detergent with an ajustable mean of M ounces and a fixed standard deviation of .2 ounces. The amount dispensed is approximately normally distributed. what choice should be made of the mean M so that at least 99.5% of all boxes labelled 40 ounces will actually contain at least 40 ounces?

“angiographically significant” coronary stenosis is considered to be present when the diameter is reduced by more than 50%, corresponding to a reduction in cross-sectional area greater than 75%.
I really don't understand this statement...and by he way how do you test for ventricular ejection fraction?

The Question: A rectangular pen is to be constructed from 1500 feet of fencing. One pair of opposite sides must be double thickness of fencing while the other pair of opposite sides must be triple thickness. Find the dimensions of the pen to maximize its area.

What I tried:

A = B*H
1500= 3B * 2H
H= (3B/2)-1500

A= 3B * 2(3B/2)-1500

I don't know what i did wrong, but once i enter it into the calculator to find the max (Note: im in precalc not calculus so we still use the calculator for this kind of problem) It doesn't give me a specific max which leads me to think that i did something wrong up above trying to find the function.

Can someone tell me what I did wrong?

the sky was clear and in the distance I saw what seem to me a white dove or a white bird then didn't notice wings flapping, Ok next thought a helicopter or airplane it was slowly climbing towards the sky at an angle, it had a shape like a "tear drop" it wasn't a helicopter or airplane, then kept watching it for couple of seconds and just disappeared , i thought maybe it made a turn because i've seen airplanes where they make a turn and seem like they disappear but didn't, i kept watching but nothing the thing or aircraft was gone. any ideas??

If you dont believe in anything having to do with anything paranormal, why do you insist on being here.Do you feel like your smarter, better educated. Science is supposed to be open minded about any subject, yet a lot of you quote science and are so closed minded about everything that has to do with the paranormal. I admit, I find certain aspects hard to believe myself. But I went from being a skeptic to believing because I have had activity happen around me.
I could argue with you that evolution is pure theory, to show me unequivacle proof, and you cannot do it. Evolution has never been proven, its just an accepted theory. Science is still looking for the proof to this moment.
Science says there was a Big Bang to start the universe, but they cant say what caused it, therefore its just a theory. Its accepted as fact yet there is no proof it happened.
So why so closed minded about anything paranormal

If you have G = (V, T, S, P) where V= { a, b, A, B, S}, T = {a, b}

S is the start symbol, and P = {S --> ABa, A --> BB, B --> ab, AB -->, AB -->b}.

Can someone please explain how to get to the production portion of this problem as simply as possible. I just don't understand how to take information from one set and the other and make the sets to get to the production answer of this problem.

i first asked this question on http://answers.yahoo.com/question/index;_ylt=AjQxaxmnAQxwPQVIzFpolhnsy6IX;_ylv=3?qid=20071023083937AAfnneT

altho i do get some of the work. I dont get all of it. For example, i dont get this part.then just concentrate on the numerator...

1 = [A(x-1)(x+1) + Bx(x+1) + Cx(x-1)]

substitute x = 0 , 1 & -1to get the values of A,B & C...

at x = 0
1 = -A

at x = 1
1 = 2B

at x = -1
1 = 2C

thus
1/(x^3 - x) = (-1)/x + (1/2)/(x-1) + (1/2)/(x+1)

so what is A,B, and C, then? do i solve further for it or something? I'm trying but I am just really bad at math.
:(
so please help. Thanks
