  2. Arithmetic - Wikipedia

    en.wikipedia.org/wiki/Arithmetic

    Using scientific notation, a number is decomposed into the product of a number between 1 and 10, called the significand, and 10 raised to some integer power, called the exponent. The significand consists of the significant digits of the number, and is written as a leading digit 19 followed by a decimal point and a sequence of digits 0–9.

  3. Softmax function - Wikipedia

    en.wikipedia.org/wiki/Softmax_function

    In the language of tropical analysis, the softmax is a deformation or "quantization" of arg max and arg min, corresponding to using the log semiring instead of the max-plus semiring (respectively min-plus semiring), and recovering the arg max or arg min by taking the limit is called "tropicalization" or "dequantization".

  4. Equals sign - Wikipedia

    1 + 2 = 3, 3 + 3 = 6, 6 + 4 = 10, 10 + 5 = 15. This difficulty results from subtly different uses of the sign in education. In early, arithmetic-focused grades, the equal sign may be operational ; like the equal button on an electronic calculator, it demands the result of a calculation.

    The partial sums of the series 1 + 2 + 3 + 4 + 5 + 6 + ⋯ are 1, 3, 6, 10, 15, etc.The nth partial sum is given by a simple formula: = = (+). This equation was known ...

  6. Binomial distribution - Wikipedia

    en.wikipedia.org/wiki/Binomial_distribution

    The Bernoulli distribution is a special case of the binomial distribution, where n = 1. Symbolically, X ~ B(1, p) has the same meaning as X ~ Bernoulli(p). Conversely, any binomial distribution, B(n, p), is the distribution of the sum of n independent Bernoulli trials, Bernoulli(p), each with the same probability p. [31]

    Their main argument is illustrated by CO 2 per capita emissions in 2023, China's levels (9.24) are almost two thirds those of the United States (13.83) and less than a sixth of those of Palau (62.59 – the country with the highest emissions of CO 2 per capita).

  8. Decibel - Wikipedia

    en.wikipedia.org/wiki/Decibel

    The decibel originates from methods used to quantify signal loss in telegraph and telephone circuits. Until the mid-1920s, the unit for loss was miles of standard cable (MSC). 1 MSC corresponded to the loss of power over one mile (approximately 1.6 km) of standard telephone cable at a frequency of 5000 radians per second (795.8 Hz), and matched closely the smallest attenuation detectable to a ...

    These three swing states were seen as evenly divided, and with each casting 20 electoral votes or more, they had the power to decide the election. As the final results came in, Kerry took Pennsylvania and then Bush took Florida, focusing all attention on Ohio.
