  2. Repeating decimal - Wikipedia

    en.wikipedia.org/wiki/Repeating_decimal

    In order to convert a rational number represented as a fraction into decimal form, one may use long division. For example, consider the rational number ⁠ 5 / 74 ⁠: 0.0 675 74 ) 5.00000 4.44 560 518 420 370 500 etc. Observe that at each step we have a remainder; the successive remainders displayed above are 56, 42, 50.

  3. Division (mathematics) - Wikipedia

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

    Give the answer as a fraction representing a rational number, so the result of the division of 26 by 11 is (or as a mixed number, so =. ) Usually the resulting fraction should be simplified: the result of the division of 52 by 22 is also 26 11 {\displaystyle {\tfrac {26}{11}}} .

  4. List of mathematical constants - Wikipedia

    en.wikipedia.org/wiki/List_of_mathematical_constants

    The following list includes the continued fractions of some constants and is sorted by their representations. Continued fractions with more than 20 known terms have been truncated, with an ellipsis to show that they continue. Rational numbers have two continued fractions; the version in this list is the shorter one.

  5. Odds ratio - Wikipedia

    en.wikipedia.org/wiki/Odds_ratio

    A number of alternative estimators of the odds ratio have been proposed to address limitations of the sample odds ratio. One alternative estimator is the conditional maximum likelihood estimator, which conditions on the row and column margins when forming the likelihood to maximize (as in Fisher's exact test ). [ 16 ]

  6. Enzyme kinetics - Wikipedia

    en.wikipedia.org/wiki/Enzyme_kinetics

    This example assumes the simplest case of a reaction with one substrate and one product. Such cases exist: for example, a mutase such as phosphoglucomutase catalyses the transfer of a phosphate group from one position to another, and isomerase is a more general term for an enzyme that catalyses any one-substrate one-product reaction, such as ...

  7. Microprocessor chronology - Wikipedia

    en.wikipedia.org/wiki/Microprocessor_chronology

    By reducing the number of flawed chips, from about 70% to 10%, the cost of complex designs like early microprocessors fell by the same amount. Systems based on contact aligners cost on the order of $300 in single-unit quantities, the MOS 6502 , designed specifically to take advantage of these improvements, cost only $25.

  8. Toronto - Wikipedia

    The number of impoverished seniors increased from 10.5 percent in 2011 to 12.1 percent in 2014. Toronto's 2013 child poverty rate was 28.6 percent, the highest among large Canadian cities of 500,000 or more residents.

  9. Dark matter - Wikipedia

    en.wikipedia.org/wiki/Dark_matter

    [18] [19] Wm. Thomson, Lord Kelvin, discussed the potential number of stars around the Sun in the appendices of a book based on a series of lectures given in 1884 in Baltimore. [ 20 ] [ 18 ] He inferred their density using the observed velocity dispersion of the stars near the Sun, assuming that the Sun was 20–100 million years old.
