Quizlet was founded in October 2005 by Andrew Sutherland, who at the time was a 15-year old student, [2] and released to the public in January 2007. [3] Quizlet's primary products include digital flash cards, matching games, practice electronic assessments, and live quizzes. In 2017, 1 in 2 high school students used Quizlet. [4]
Average physical product (APP), marginal physical product (MPP) In economics and in particular neoclassical economics, the marginal product or marginal physical productivity of an input (factor of production) is the change in output resulting from employing one more unit of a particular input (for instance, the change in output when a firm's labor is increased from five to six units), assuming ...
Personal life, the course of an individual's life; Everyday life, the ways in which people typically act, think, and feel on a daily basis; Human condition, the characteristics and key events that compose the essentials of human existence; Human rights, principles or norms that describe certain standards of human behaviour and are regularly ...
In the first case, the bond is divided so that each product retains an electron and becomes a neutral radical. In the second case, both electrons of the chemical bond remain with one of the products, resulting in charged ions. Dissociation plays an important role in triggering chain reactions, such as hydrogen–oxygen or polymerization reactions.
The UK's average ecological footprint is 5.45 global hectares per capita (gha) with variations between regions ranging from 4.80 gha (Wales) to 5.56 gha (East England). [ 40 ] BedZED , a 96-home mixed-income housing development in South London , was designed by Bill Dunster Architects and sustainability consultants BioRegional for the Peabody ...

The mean chain length of an entire web is the arithmetic average of the lengths of all chains in a food web. [ 42 ] [ 14 ] In a simple predator-prey example, a deer is one step removed from the plants it eats (chain length = 1) and a wolf that eats the deer is two steps removed from the plants (chain length = 2).
1. The Average Fixed Cost curve (AFC) starts from a height and goes on declining continuously as production increases. 2. The Average Variable Cost curve, Average Cost curve and the Marginal Cost curve start from a height, reach the minimum points, then rise sharply and continuously. 3. The Average Fixed Cost curve approaches zero asymptotically.
