WebJan 18, 2024 · Step 5: Divide the sum of squares by n – 1 or N. Divide the sum of the squares by n – 1 (for a sample) or N (for a population). Since we’re working with a sample, we’ll use n – 1, where n = 6. Variance. 886 (6 – 1) = 886 5 = 177.2. WebFirst: Find the constant of variation, by writing the model (the equation) for direct variation: y= kx y = k x. Plug the given y y and x x into the model. Solve for k k, which is the constant of variation. Second: Write the equation of variation by plugging the constant of variation into the equation y= kx y = k x. bjc hospital wentzville mo

WebExample 1: A quantity varies inversely as two or more other quantities. The figure below shows a rectangular solid with a fixed volume. Express its width, w, as a joint variation in terms of its length, l, and height, h. Solution: w ∝ 1/ (lh) In other words, the longer the length l or the height h, the narrower is the width w. WebExample 3. Given the combined variation equation , find x when y = 2 and z = 10. This is just your basic, run-of-the-mill algebra problem. We wanna solve for x, so multiply both sides by z: yz = 4 x. Now plug in y = 2 and z = 10: 2 (10) = 4 x. 20 = 4 x. bjc hospital rankingWebDirect Variation Set up the variation equation with k in it.
