Variation .. direct variation?

usually an initial pair (N,T(N)) is given so that k can be determined then further calculations with the formula inculding the unique k value can be done

The variation, could be frankly anything, because it arises from mutations. It could be anything from a different shell colour for a beetle, to a different beak shape for a bird.\n\nHow does it spread? Well, through mating. Organisms mate, they produce offspring. Some will have the mutation. Others won't. The mutation will only take a hold in the population, if it gives the particular organisms that have it, an advantage. So, it doesn't so much as spread, as that it outlasts the other variations.\n\nOf course, even this description doesn't do it justice. I suggest you really, look into the below sources and remember that the Wikipedia article is open to vandalism by Creationists and IDers that don't know what they're talking about.

The coefficient of variation just compares the standard deviation to the mean.  It is calculated S.D./ Mean sometimes * 100.  It is difficult to compare standard deviations of variables where the units are not the same.  For example if one variable had units in million of dollars and another in cents how do you compare their variability?  One way to compare them and get an idea of their variability is to use the C.V.

Since it is a direct variation we can use the formula\n\ny = k x\n\nSince we are given the ordered pair (2,4) we know y=4 when x=2. Plugging these values into the formula gives us\n\n4 = k(2)\n\nTo solve for k we divide both sides by 2 which gives us\n\nk = 2.\n\nIt would also be correct to set up the variation to be\n\nx = k y\n\nIn this case, we do the same procedures to find k. Plug in the known values for x and y to get that k = 1/2. Unless you are told which one to solve for either are correct. If you are given a multiple choice test I would think that only one could be a possible answer, unless you are first given the variation equation.

vary from state to state...

don't do always the same stuff, vary positions and locations.....enjoy!

No. You are either complete or not. There is no variation. You can't be slightly complete, as there is only one way of being complete. Therefore if you are not complete you are definatly incomplete.\n\nAnyway, entirely incomplete sounds nicer ;-)

The variation rate is not a percentage, but the variation over time. You can express the variation as a percentage: Value 2 - Value 1 divided by Value 1 gives you the percentage increase. It can be used as the rate of growth between the dates of V1 and V2 only, and only if you know the time interval.

there are lots of varial ... from body varial to varial kickflip....but i don`t know varial .... just varial flip :D

varies with each individual.

both but in different ways

The equation for direct variation is y = kx.\nk is the constant of variation.\n\n#1.  -10 = k(2)    Solve for k\n           -5 = k\nSo, the equation for direct variation is y = -5x -- just substitute the k back into the equation.\n\n#2.  7 = k(3)   Solve for k\n       7/3 = k\n     y = (7/3)x

Direct variation when applied to two variables x and y is usually expressed in the form:\n\ny= k*x   where is k is the constant of variation\n\nSo y/x = k\n\nFrom your first values for x and y, you can determine k:\n\n-4.8/-1.6 = k = 3\n\nNote: x = y/k, so from your 2nd value for y, and from k = 3, you can determine the 2nd value for x:\n\nx = -24/3 = -8\n\nAs far as slopes go, you know that the standard form for the equation of a line is:\n\ny = mx+b  where m is the slope and b is the y intercept (i.e. when x = 0)\n\nYou can see that your example of direct variation is equivalent to a line having slope k, and passing through the origin (0,0) so b=0.\n\nDirect variation is the same as direct proportonality:\n\nhttp://mathworld.wolfram.com/DirectlyProportional.html

I would say variance, but I'm no statistics expert.
