  2. Division (mathematics) - Wikipedia

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

    In terms of partition, 20 / 5 means the size of each of 5 parts into which a set of size 20 is divided. For example, 20 apples divide into five groups of four apples, meaning that "twenty divided by five is equal to four". This is denoted as 20 / 5 = 4, or ⁠ 20 / 5 ⁠ = 4. [2] In the example, 20 is the dividend, 5 is the divisor, and 4 is ...

  3. Modulo - Wikipedia

    en.wikipedia.org/wiki/Modulo

    [1] For example, the expression "5 mod 2" evaluates to 1, because 5 divided by 2 has a quotient of 2 and a remainder of 1, while "9 mod 3" would evaluate to 0, because 9 divided by 3 has a quotient of 3 and a remainder of 0. Although typically performed with a and n both being integers, many computing systems now allow other types of numeric ...

  4. Repeating decimal - Wikipedia

    en.wikipedia.org/wiki/Repeating_decimal

    The period of ⁠ c / k ⁠, for c coprime to k, equals the period of ⁠ 1 / k ⁠. If k = 2 a ·5 b n where n > 1 and n is not divisible by 2 or 5, then the length of the transient of ⁠ 1 / k ⁠ is max(a, b), and the period equals r, where r is the multiplicative order of 10 mod n, that is the smallest integer such that 10 r ≡ 1 (mod n).

  5. Chi-squared distribution - Wikipedia

    en.wikipedia.org/wiki/Chi-squared_distribution

    An additional reason that the chi-squared distribution is widely used is that it turns up as the large sample distribution of generalized likelihood ratio tests (LRT). [8] LRTs have several desirable properties; in particular, simple LRTs commonly provide the highest power to reject the null hypothesis ( Neyman–Pearson lemma ) and this leads ...

  6. Mitella diphylla - Wikipedia

    en.wikipedia.org/wiki/Mitella_diphylla

    Tiny flowers with finely divided, lacy white petals are produced in mid-spring in racemes on stems growing from 20 to 50 cm (8 to 20 in) tall. The seeds are tiny, 1.2–1.6 mm (0.05–0.06 in), [ 5 ] produced in small green cups, formed from the sepals of the flower, and when ripe are shiny and black. [ 6 ]

    A 30-year-old man survived a blood alcohol concentration of 1.5% after vigorous medical intervention that included dialysis and intravenous therapy with fructose. [50] Survived 1995 1.48 Wrocław, Poland: In 1995, a man from Wrocław, Poland, caused a car accident near his hometown. He had a blood alcohol content of 1.48%; he was tested five ...

    1025 Riema, provisional designation 1923 NX, is a bright Hungaria asteroid from the innermost regions of the asteroid belt, approximately 5 kilometers in diameter.It was discovered on 12 August 1923, by German astronomer Karl Reinmuth at the Heidelberg Observatory in southwest Germany. [17]

  9. Non-methane volatile organic compound - Wikipedia

    en.wikipedia.org/wiki/Non-methane_volatile...

    Non-methane volatile organic compounds (NMVOCs) are a set of organic compounds that are typically photochemically reactive in the atmosphere—marked by the exclusion of methane. [1] NMVOCs include a large variety of chemically different compounds, such as benzene, ethanol, formaldehyde, cyclohexane, 1,1,1-trichloroethane and acetone. [2]
