  2. Linear inequality - Wikipedia

    en.wikipedia.org/wiki/Linear_inequality

    The line that determines the half-planes (ax + by = c) is not included in the solution set when the inequality is strict. A simple procedure to determine which half-plane is in the solution set is to calculate the value of ax + by at a point (x 0, y 0) which is not on the line and observe whether or not the inequality is satisfied.

  3. Decoupling of wages from productivity - Wikipedia

    en.wikipedia.org/wiki/Decoupling_of_wages_from...

    Average wages (solid line) vs GDP per hour worked (dotted line) in the G7 from 1990 to 2020. On average across 24 OECD countries, there has been significant decoupling of real median wage growth from productivity growth over the past two decades.

  4. Stoner–Wohlfarth model - Wikipedia

    en.wikipedia.org/wiki/Stoner–Wohlfarth_model

    The solid red and blue curves are energy minima, the dashed red and blue lines are energy maxima. Energy profiles are included for three vertical profiles (insets). For each angle θ between easy axis and field, equation has a solution that consists of two solution curves. It is trivial to solve for these curves by varying φ and solving for h.

  5. Jensen's inequality - Wikipedia

    en.wikipedia.org/wiki/Jensen's_inequality

    A graphical "proof" of Jensen's inequality for the probabilistic case. The dashed curve along the X axis is the hypothetical distribution of X, while the dashed curve along the Y axis is the corresponding distribution of Y values. Note that the convex mapping Y(X) increasingly "stretches" the distribution for increasing values of X.

  6. Inequality (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Inequality_(mathematics)

    The feasible regions of linear programming are defined by a set of inequalities. In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. [1] It is used most often to compare two numbers on the number line by their size.

  7. Inequation - Wikipedia

    en.wikipedia.org/wiki/Inequation

    In mathematics, an inequation is a statement that an inequality holds between two values. [1] [2] It is usually written in the form of a pair of expressions denoting the values in question, with a relational sign between them indicating the specific inequality relation.

  8. k-nearest neighbors algorithm - Wikipedia

    en.wikipedia.org/wiki/K-nearest_neighbors_algorithm

    The test sample (green dot) should be classified either to blue squares or to red triangles. If k = 3 (solid line circle) it is assigned to the red triangles because there are 2 triangles and only 1 square inside the inner circle. If k = 5 (dashed line circle) it is assigned to the blue squares (3 squares vs. 2 triangles inside the outer circle).

  9. Wage subsidy - Wikipedia

    en.wikipedia.org/wiki/Wage_subsidy

    In a conventional system the tax payable on an income y may be shown by the solid red line in the diagram, where θ is the threshold. Under a wage subsidy the employee's contribution to the state might be shown by the broken line below θ, being negative for workers on low income. s is the amount of the subsidy.
