S xx = (∑X i 2) – n*X̅ 2. The proof of the fact that both these formulas are equal can be found here. S xy Formula: The Sxy value can be calculated using the formula, Sxy = Σ (X i – X̄)(Y i – Ȳ). Alternatively, we can also use the following alternative formula, S xy …Thus, we can summarize some properties of the correlation coefficient as follows. ρ(aX + b, cY + d) = ρ(X, Y) for a, c > 0. - If ρ(X, Y) = 0, we say that X and Y are uncorrelated. - If ρ(X, Y) > 0, we say that X and Y are positively correlated. - If ρ(X, Y) < 0, we say that X and Y are negatively correlated.Females typically have two X chromosomes (46,XX), and males have one X chromosome and one Y chromosome in each cell. 47,XYY syndrome is caused by the presence of an extra copy of the Y chromosome in each of a male's cells. As a result of the extra Y chromosome, each cell has a total of 47 chromosomes instead of the usual 46.Solution. THEOREM 3 (a) Law of Absorption : yx+x = x. yx+x = yx+x1 by identity (Ax. 2b) = x (y+1) by distributivity (Ax. 4a) = x1 by Theorem 2 (a) = x by identity (Ax. 2b) THEOREM 3 (b): x (x+y) = x by duality. THEOREM 6 (a) De Morgan's Laws: (x+y)' = x'y'. Proof: We will prove that x'y' is a complement of x+y by proving that x'y' satisfies ...P(x, y) x y 5 5 −5 −5 O N If we take any point P(x,y) on the circle, then OP = 5 is the radius of the circle. But OP is also the hypotenuse of the right-angled triangle OPN, formed when we drop a perpendicular from P to the x-axis. Now in the right-angled triangle, ON = x and NP = y. Thus, using the theorem of Pythagoras, x 2+y2 = 5 = 25.

To add to the answer from Ian Miller, Sxx = ∑x2 − (∑ x)2 n = ∑x2 − nx¯2 S x x = ∑ x 2 − ( ∑ x) 2 n = ∑ x 2 − n x ¯ 2. Intuitively, Sxy S x y is the result when you replace one of the x x 's with a y y. Sxy = ∑ xy − ∑ x ∑ y n = ∑ xy − nx¯y¯ S x y = ∑ x y − ∑ x ∑ …

1. Yes, ∃x∀y(P(x, y)) ∃ x ∀ y ( P ( x, y)) means that there is a x x such that, for every y y, P(x, y) P ( x, y) holds. There is nothing peculiar here. The existential quantifier should always be read as if there was a "such that" after it. For instance, ∃x(P(x) → Q(x)) ∃ x ( P ( x) → Q ( x)) means that there is a x x such ...
