What Is Chebyshev's Inequality? Chebyshev’s inequality says that at least 1-1/K2 of data from a sample must fall within K standard deviations from the mean (here K is any positive real number greater than one). Any data set that is normally distributed, or in the shape of a bell curve, has several features.

phase rule A rule used in thermodynamics stating that the number of degrees of freedom in a physical system at equilibrium is equal to the number of chemical components in the system minus the number of phases plus the constant 2. Also called Gibbs phase rule.

What is the Chevron Doctrine and why is it so important? So the Chevron Doctrine (also called Chevron deference) basically has come to mean a set of rules by which a judge can fairly review the decisions of a federal agency without acting improperly, in defiance of a legitimate agency or Act of Congress.

What Is Chebyshev's Inequality? So Chebyshev’s inequality says that at least 75% of the data values of any distribution must be within two standard deviations of the mean. For K = 3 we have 1 – 1/K 2 = 1 - 1/9 = 8/9 = 89%. So Chebyshev’s inequality says that at least 89% of the data values of any distribution must be within three standard deviations of the mean. For K = 4 we have 1 – 1/K 2 = 1 - 1/16 = 15/16 = 93.75%.

Rule of sum In combinatorics, the rule of sum or addition principle is a basic counting principle. Stated simply, it is the idea that if we have a ways of doing something and b ways of doing another thing and we can not do both at the same time, then there are a + b ways to choose one of the actions.

- Chelyabinsk meteor. The Chelyabinsk meteor was a superbolide caused by an approximately 20-metre near-Earth asteroid that entered Earth's atmosphere over Russia on 15 February 2013 at about 09:20 YEKT (03:20 UTC), with a speed of 19.16 ± 0.15 kilometres per second (60,000–69,000 km/h or 40,000–42,900 mph).

- Lavrushka was one of those coarse, bare-faced lackeys who have seen all sorts of things, consider it necessary to do everything in a mean and cunning way, are ready to render any sort of service to their master, and are keen at guessing their master's baser impulses, especially those prompted by vanity and pettiness.

Scientific Principles Scientific Principles. Structure of Metals: Metals account for about two thirds of all the elements and about 24% of the mass of the planet. They are all around us in such forms as steel structures, copper wires, aluminum foil, and gold jewelry. Metals are widely used because of their properties: strength, ductility, high melting point, thermal and electrical conductivity, and toughness. These properties also offer clues as to the structure of metals.

Carter and Brezhnev sign the SALT-II treaty In June 1979, Carter and Brezhnev met in Vienna and signed the SALT-II agreement. The treaty basically established numerical equality between the two nations in terms of nuclear weapons delivery systems. It also limited the number of MIRV missiles (missiles with multiple, independent nuclear warheads).

Davis's law For the journalism maxim sometimes known as Davis's law, see Betteridge's law of headlines. Davis's law is used in anatomy and physiology to describe how soft tissue models along imposed demands. It is the corollary to Wolff's law, which applies to osseous tissue. It is a physiological principle stating that soft tissue heal according to the manner in which they are mechanically stressed.

What Does Charles' Law State? Charles' law is also known as the law of volumes, with an equation indicating that volume divided by temperature equals the constant. This equation is easier to determine if a gas is maintained at a constant pressure and the constant changes only by the increase or decrease in temperature.

- Geologists establish the relative ages of rocks mostly through their understanding of stratigraphic succession. The Principle of Original Horizontality states that all rock layers were originally horizontal. The Law of Superposition states that younger strata lie on top of older strata.riginal Horizontality. In order to establish relative dates, geologists must make an initial assumption about the way rock strata are formed. It's called the Principle of Original Horizontality, and it just means what it sounds like: that all rock layers were originally horizontal.

Avogadro's law Avogadro’s law. Avogadro’s law, a statement that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules. This empirical relation can be derived from the kinetic theory of gases under the assumption of a perfect (ideal) gas.

Did man really land on the moon? Along those same lines, another reader (Norton) pointed out the lack of stars in a shot closer to Earth: “I was curious to see stars in this image of earth, yet in most other images the stars aren’t visible. In one of your images of the day a week or two later, there are no stars visible.

The compass is showing you what direction the magnetic field is in, so you can use the right hand rule to work out whether the current is flowing north to south or south to north.
