VED stands for Vital, Essential, Desirable.\nIts a dependable method of valuation of inventory.Under this system the inventory is divided into various categories viz Vital, which is really important and in this category the stock out leads to total failure.\nThe Essential items are just that, i mean essential.Although the stock out can b avoided, it cant b tolerated for long.\nThe Desirable items are just reqd for easy working and avoiding strain.There is no stock out cost associated wid this category of items.

start with   d = m / v        multiply both side by v; \nyou get     v * d = m        divide both sides by d; \nyou get     v = m / d

The standard deviation is the square root of the variance. Now, the variance is the "average squared difference (distance) of each observation from the mean".\n \nLets think about it. You want a measure of how dispersed the data is, right? Well, suppose you have heights for your data and your trying to compare two groups. For example, you want to know if the height´s of New Yorkers vary more or less than the heights of Floridians. You are NOT trying to see which are taller.\n \nSo you can calculate the average height of each group and then see haw far away from this average each individual height is and then calculate the average distance from the average height. If everyone had the same height, the average distance would be ZERO, reflecting that the population´s height is very CONCENTRATED around its average.\n \nBut why do you use the squared difference? Because if you were to calculate the average of "x - average(x)" you would always get zero, so by squaring and taking the square, you always get a positive number (the distance is always positive).\n \nGot it?

It is similar to calculating the area. \n\nIt is a product of Length and Width (L x W).

You might be looking for Regression analysis.\nThis is the statistical technique used to look for correlations between variables.

Load the Analysis Toolpak add-in and then use this formula, it's shorter:\n\n=A1/GCD(A1, B1)&":"&B1/GCD(A1, B1)

This is more of a physics question...\nd final = .5*a*t^2 + v*t + d\nv final = a*t + v\nd is displacement, v is velocity, a is acceleration.\nEnjoy.

PV=nRT\n\nn is doubled.\nT, V same.\nR is constant\n\n=>P has to be doubled to validate the eqn.

Quantitative methodologies... statistical analysis?   How many pages allowed on here... there are books and books about it... try reading literature on the above... infinite (well almost!) sources available on line, at the library and in book shops

velcoity is change in displacement/time

D= M/V\n\nIts a formula used to calulated to density (thinkness) of an object by dividing the Mass of an object by its volume. In this case, you can use the water displacement method that displaces (water) from its orignal volume by adding an object (marble). Using a balancer, measure and record the weight of graduated cylinder(ml), before and after the addition of water. Subtract the weight of the cylinder with water from the cyliner's weight and you will get the mass. You have to pay attention to how much the water displacement after adding the marble. record the volumes before and after (if ness). This will solve for volume. Once this is accomplished, you would have no problem finding the density.

It is based on mean and standard deviations (statistical stuff). With just the information you gave, it is impossible to tell.\nWe would need to know the mean, standard devaition, and method of calculating scale...but then again if we had all this stuuf you would be able to asnwer your own question, right?

Bloodstain pattern analysis is used to determine the direction and (subjectively) the speed of a drop of blood at an incident scene.  Round drops are typically indicative of blood falling from above.  Blood drops that land at oblique angles will form a teardrop shape.  The "tail" end of the pattern points to the direction that the blood came from and the length of the tail is an indicator of speed (the longer the tail, the greater the speed).  Inferences about the incident can possibly drawn from there, but are usually corroborated with other physical evidence.\n\nLarger pools of blood can be used to determine the location of a body or the extent of bleeding or some other needed information.  Again, this is usually corroborated with other physical evidence and its usefullness is determined case by case.

If v^2 is proportional to Fc, then v^2 = k*Fc, where k is a constant.  For each of your values of v and Fc, calculate k = v^2/Fc;\n\nYou will get the following values for k:\n\n39.51, 37.97, 33.61, 32\n\nThese average to 35.77 and the standard deviation is about 10%, which would be considered a good fit and that the formula\n\nV^2 = 35.77*Fc fits those values pretty well.

Standard deviation is a measure of the variability in a sample.  A small standard deviation means that most observations are clost to the mean (average).  The standard deviation is the square root of the variance.  The variance is calculated by taking the difference between each observation and the mean, squaring it, summing for all observations, then dividing by the number of observations less one.\n\nwith m = mean and X1 ... Xn being the observations:\n\nvariance: V = [(X1-m)^2 + (X2-m)^2 ... + (Xn-m)^2] / (n-1)\nstandard deviation: sigma = sqrt(V)

dimensional analysis is solving a problem by using the units of the terms involved.\n\nfor instance, since volume density has units of mass / volume, you know how to find volume density given a mass and a volume, it would just be: mass/volume = density.\n\na more complicated example force (F) has units of newtons. Newtons can be further broken down into the units (kilogram * meters)/seconds^2\n\nthus, if you know the mass of an object (kilograms), and the acceleration (meters/second^2), you then know how to put the two together to find force, it would just be:\n\nkilograms * (meters/seconds^2)\n\nwhich is mass*acceleration.\n\nthis type of analysis can be strung together to solve more complicated problems.
