If Y denotes a temperature recorded in degrees Fahrenheit, then (5/9)*(Y-32) is the corresponding temperature in degrees Celsius. If the standard deviation for a set of temperatures is 15.7 degrees Fahrenheit, what is the standard deviation of the equivalent Celsius temperature?

Is the answer a simple conversion from 15.7 degrees Fahrenheit to degrees Celsius? -9.055556 degrees Celsius??

Hi pplz!
Im a 3rd year chemistry student at uni but am on a placement therefore ive been sent a bunch of notes thru the post. I was meant to have read the notes nd dun these qs in dec and as its feb, my exams r in march and i STILL dont get the notes (they r RUBBISH nd my lecturer is a bit of a meanie so i dont wanna ring him for help) plzzzz can sum1 help me on here!?!
Basically i am totally not understanding my NMR spectroscopy module - i basically learn best by simple examples and simple instructions on how 2 do things ie for proton nmr last year i had 2 buy a book with simple examples like ethanol for me to get intergrations, peak heights etc. I need similar help now - can some1 plz give me step by step instructions on how to assign peaks for COSY, NOEDIF, PENDANT, HMQC and HMBC and also explain really simply wat they r (or point me to a good website where i can learn) - i will b generous with the points for the best asnwer :D
Thanks!!

ok so here is the question. :
Compute the equation of the plane which lies one forth of the way from the plane
r * (2,-3,1) = 5
to the plane
r * (-6, 9, -3) = -1


I'm thinking its not too difficult of a problem but I havn't done math in over 3 yrs now.
This is what i have so far.
x + 1/4 (y - x) = 1/4y + 3/4x
now putting this into the plane equation, I get a little confused on how to subtract one plane from another.

In a triangle with vertices ABC and center point O, there exists 3 medians. AMa, BMb, and CMc. If AMa = 156 and CMc = 204, can the triangle be solved and how? I say it cannot be solved but my teacher says it can

If it cannot be solved, then what are at least 2 triangles that use those medians so I can show it has at least more than one answer.

I can solve the medians into parts:
AO= 104
OMa = 52
CO = 136
OMc = 68
But that is about it

I have looked at working with a parallelogram involving OMa and a/2 seeking to use a^2 + b^2 + c^2 + d^2 = x^2 + y^2 where a, b, c, d are the parallelogram sides and x and y are the parallelogram diagonals. I have tried to use the equal areas of the six small triangles also with no luck. I solved AOMc and COMa for cos theta and solved the equations against each other but that left me with 2 unknowns
