For n ≥ r ≥ 0. The formula show us the number of ways a sample of “r” elements can be obtained from a larger set of “n” distinguishable objects where order does not matter and repetitions are not allowed. [1] "The number of ways of picking r unordered outcomes from n possibilities." [2]The formula for a circle is (x−a) 2 + (y−b) 2 = r 2. So the center is at (4,2) And r 2 is 25, so the radius is √25 = 5. So we can plot: The Center: (4,2) Up: (4,2+5) = (4,7) Down: (4,2−5) = (4,−3) Left: (4−5,2) = (−1,2) Right: (4+5,2) = (9,2)List of Mathematical Symbols R = real numbers, Z = integers, N=natural numbers, Q = rational numbers, P = irrational numbers. ˆ= proper subset (not the whole thing) =subsetThe only way I know to do this well is to flip the model and use the 'tikz' LaTEX package to draw the whole graphic manually from within the LaTEX file or to use the 'pixmap' R package to draw an image of my expression on top of the plot. Neither feels like a perfect approach.While this is a serious limitation, multi-level formulas are not always needed and even when they are needed, proper math symbols still look better than improvised ASCII approximations.

Separate lines with \\ and use & to mark where things should line up. Note: No dollar signs are needed when you use this method. Example ThisA square is a special type of a rectangle, where all the sides are equal. Because of that, the formula for finding a square is simpler than that for finding a rectangle: A = S x S. where "A" stands for the area and "S" represents the length of one side. You simply multiply two sides to find the area, since all sides of a square are equal.Therefore, the quadratic model is either as accurate as, or more accurate than, the linear model for the same data. Recall that the stronger the correlation (i.e. the greater the accuracy of the model), the higher the R^2. So the R^2 for the quadratic model is greater than or equal to the R^2 for the linear model.
