In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own boolean-valued outcome: success/yes/true/one or failure/no/false/zero. A single success/failure experiment is also called a Bernoulli trial or Bernoulli experiment and a sequence of outcomes is called a Bernoulli process; for a single trial, i.e., n = 1, the binomial distribution is a Bernoulli distribution. The binomial distribution is the basis for the popular binomial test of statistical significance.
In mathematics, the Fibonacci numbers, commonly denoted Fn, form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from 0 and 1. That is,

K2, at 8,611 metres (28,251 ft) above sea level, is the second highest mountain in the world, after Mount Everest at 8,848 metres (29,029 ft). It is located on the China–Pakistan border between Baltistan in the Gilgit-Baltistan region of northern Pakistan, and Dafdar Township in Taxkorgan Tajik Autonomous County of Xinjiang, China. K2 is the highest point of the Karakoram range and the highest point in both Pakistan and Xinjiang.
Philip Kindred Dick was an American writer known for his work in science fiction. He produced 44 published novels and approximately 121 short stories, most of which appeared in science fiction magazines during his lifetime. His fiction explored varied philosophical and social themes, and featured recurrent elements such as alternate realities, simulacra, large corporations, drug abuse, authoritarian governments, and altered states of consciousness. His work was concerned with questions surrounding the nature of reality, perception, human nature, and identity.
In chemistry, pH is a scale used to specify how acidic or basic a water-based solution is. Acidic solutions have a lower pH, while basic solutions have a higher pH. At room temperature, pure water is neither acidic nor basic and has a pH of 7.
In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.
Vitamin K is a group of structurally similar, fat-soluble vitamins found in foods and in dietary supplements. The human body requires vitamin K for complete synthesis of certain proteins that are needed for blood coagulation or for controlling binding of calcium in bones and other tissues. The complete synthesis involves final modification of these so-called "Gla proteins" by the enzyme gamma-glutamyl carboxylase that uses vitamin K as a cofactor. This modification allows them to bind (chelate) calcium ions, which they cannot do otherwise.
The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of many gases under many conditions, although it has several limitations. It was first stated by Émile Clapeyron in 1834 as a combination of the empirical Boyle's law, Charles's law, Avogadro's law, and Gay-Lussac's law. The ideal gas law is often written in an empirical form:
2 (two) is a number, numeral, and glyph. It is the natural number following 1 and preceding 3. It is the smallest and only even prime number. Because it forms the basis of a duality, it has religious and spiritual significance in many cultures.
In biochemistry, Michaelis–Menten kinetics is one of the best-known models of enzyme kinetics. It is named after German biochemist Leonor Michaelis and Canadian physician Maud Menten. The model takes the form of an equation describing the rate of enzymatic reactions, by relating reaction rate to , the concentration of a substrate S. Its formula is given by
K-pop is a genre of popular music originating in South Korea. While the modern form of K-pop can be traced back to the early 90s, the term itself has been popularized since the 2000s, replacing the term Gayo (가요), which also refers to domestic pop music in South Korea. Although it generally indicates "popular music" within South Korea, the term is often used in a narrower sense to describe a modern form of South Korean pop that is influenced by styles and genres from around the world, such as experimental, rock, jazz, gospel, hip hop, R&B, reggae, electronic dance, folk, country, and classical on top of its traditional Korean music roots. The more modern form of the genre emerged with the formation of one of the earliest K-pop groups, Seo Taiji and Boys, in 1992. Their experimentation with different styles and genres of music and integration of foreign musical elements helped reshape and modernize South Korea's contemporary music scene.

The GfK Entertainment charts are the official music charts in Germany and are gathered and published by GfK Entertainment, a subsidiary of GfK SE, on behalf of Bundesverband Musikindustrie. GfK Entertainment is the provider of weekly Top 100 single & album charts, as well as various other chart formats for genres like compilations, jazz, classical music, schlager, hip hop, dance, comedy, and music videos. Following a lawsuit in March 2014 by Media Control AG, Media Control® GfK International had to change its name.
The kelvin is the base unit of temperature in the International System of Units (SI), having the unit symbol K. It is named after the Belfast-born, Glasgow University engineer and physicist William Thomson, 1st Baron Kelvin (1824–1907).
In probability theory and statistics, the Poisson distribution, named after French mathematician Siméon Denis Poisson, is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant mean rate and independently of the time since the last event. The Poisson distribution can also be used for the number of events in other specified intervals such as distance, area or volume.
4K resolution refers to a horizontal display resolution of approximately 4,000 pixels. Digital television and digital cinematography commonly use several different 4K resolutions. In television and consumer media, 3840 × 2160 is the dominant 4K standard, whereas the movie projection industry uses 4096 × 2160.
The COVID-19 pandemic in Poland is part of the worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. In February and March 2020, health authorities in Poland carried out laboratory testing of suspected cases of infection by SARS-CoV-2, one of the seven known human coronaviruses, as well as home quarantining and monitoring. The first case of a laboratory confirmed SARS-CoV-2 infection in Poland was that of a man hospitalised in Zielona Góra, with confirmation announced officially on 4 March 2020. The local transmission phase of SARS-CoV-2 in Poland was declared to the World Health Organization on 10 March. The first death from coronavirus disease 2019 (COVID-19) in Poland was that of a 56-year-old woman on 12 March. Polish authorities did not participate in the 28 February 2020 European Union tender procedure for purchasing COVID-19 pandemic related medical equipment, in which 20 other member states participated. Poland applied on 6 March for the 17 March tender for the purchase of gloves, goggles, face shields, surgical masks and protective clothing; the European Commission stated that all requests in the tender were satisfied by offers.
