Let X (integrable) be a random variable with finite non-zero variance σ 2 (and thus finite expected value μ). [9] Then for any real number k > 0, (| |).Only the case > is useful. . When the right-hand side and the inequality is trivial as all probabilities are ≤
For example, given that there is a pattern of odds of 5/4, 7/4, 9/4 and so on, odds which are mathematically 3/2 are more easily compared if expressed in the equivalent form 6/4. Fractional odds are also known as British odds, UK odds, [9] or, in that country, traditional odds. They are typically represented with a "/" but can also be ...
Several measures of statistical dispersion are defined in terms of the absolute deviation. The term "average absolute deviation" does not uniquely identify a measure of statistical dispersion, as there are several measures that can be used to measure absolute deviations, and there are several measures of central tendency that can be used as well.
The pound is the main unit of sterling, [4] [c] and the word pound is also used to refer to the British currency generally, [7] often qualified in international contexts as the British pound or the pound sterling. [4] Sterling is the world's oldest currency in continuous use since its inception. [8]
The Nusselt number is the ratio of total heat transfer (convection + conduction) to conductive heat transfer across a boundary. The convection and conduction heat flows are parallel to each other and to the surface normal of the boundary surface, and are all perpendicular to the mean fluid flow in the simple case.
The Universal Decimal Classification (UDC) is a bibliographic and library classification representing the systematic arrangement of all branches of human knowledge organized as a coherent system in which knowledge fields are related and inter-linked.
Although convective heat transfer can be derived analytically through dimensional analysis, exact analysis of the boundary layer, approximate integral analysis of the boundary layer and analogies between energy and momentum transfer, these analytic approaches may not offer practical solutions to all problems when there are no mathematical models applicable.
