A weighted average is a calculation where each data point contributes according to its relative importance or weight. The formula is Weighted Average = Σ(Value × Weight) / Σ(Weight). Unlike a simple arithmetic mean, assignments worth 40% impact your grade four times as much as quizzes worth 10%.
How to Find LCM and HCF (3 Methods with Examples)
The Highest Common Factor (HCF / GCD) is the largest positive integer that divides each number without remainder. The Least Common Multiple (LCM) is the smallest positive integer divisible by all numbers. For any two positive integers a and b, HCF(a, b) × LCM(a, b) = a × b.
Quadratic Formula Explained With Solved Examples
The quadratic formula x = [-b ± √(b² - 4ac)] / (2a) solves any second-degree polynomial ax² + bx + c = 0. The discriminant Δ = b² - 4ac determines root nature: Δ > 0 yields two distinct real roots, Δ = 0 yields one repeated root, and Δ < 0 yields complex conjugate roots.
