  2. Standard normal table - Wikipedia

    en.wikipedia.org/wiki/Standard_normal_table

    gives a probability that a statistic is less than Z. This equates to the area of the distribution below Z. Example: Prob(Z ≤ 0.69) = 0.7549. Complementary cumulative gives a probability that a statistic is greater than Z. This equates to the area of the distribution above Z. Example: Find Prob(Z ≥ 0.69).

  3. Blood alcohol content - Wikipedia

    en.wikipedia.org/wiki/Blood_alcohol_content

    Blood is denser than water and 1 mL of blood has a mass of approximately 1.055 grams, thus a mass-volume BAC of 1 g/L corresponds to a mass-mass BAC of 0.948 mg/g. Sweden, Denmark, Norway, Finland, Germany, and Switzerland use mass-mass concentrations in their laws, [ 6 ] but this distinction is often skipped over in public materials, [ 12 ...

  4. Color index - Wikipedia

    en.wikipedia.org/wiki/Color_index

    This is a consequence of the logarithmic magnitude scale, in which brighter objects have smaller (more negative) magnitudes than dimmer ones. For comparison, the whitish Sun has a B−V index of 0.656 ± 0.005 , [ 2 ] whereas the bluish Rigel has a B−V of −0.03 (its B magnitude is 0.09 and its V magnitude is 0.12, B−V = −0.03). [ 3 ]

  5. Repeating decimal - Wikipedia

    en.wikipedia.org/wiki/Repeating_decimal

    The repeating sequence of digits is called "repetend" which has a certain length greater than 0, also called "period". [ 5 ] In base 10, a fraction has a repeating decimal if and only if in lowest terms , its denominator has any prime factors besides 2 or 5, or in other words, cannot be expressed as 2 m 5 n , where m and n are non-negative ...

  6. Minor allele frequency - Wikipedia

    en.wikipedia.org/wiki/Minor_allele_frequency

    1. Introduce the reference of a SNP of interest, as an example: rs429358, in a database (dbSNP or other). 2. Find MAF/MinorAlleleCount link. MAF/MinorAlleleCount: C=0.1506/754 (1000 Genomes, where number of genomes sampled = N = 2504); [4] where C is the minor allele for that particular locus; 0.1506 is the frequency of the C allele (MAF), i.e. 15% within the 1000 Genomes database; and 754 is ...

  8. Low-alcohol beer - Wikipedia

    en.wikipedia.org/wiki/Low-alcohol_beer

    No alcohol or alcohol-free: not more than 0.05% ABV; Dealcoholized: over 0.05% but less than 0.5% ABV; Low-alcohol: not more than 1.2% ABV; In some parts of the European Union, beer must contain no more than 0.5% ABV if it is labelled "alcohol-free". In Australia, the term "light beer" refers to any beer with less than 3.5% alcohol.

  9. Albedo - Wikipedia

    en.wikipedia.org/wiki/Albedo

    Just as fresh snow has a higher albedo than does dirty snow, the albedo of snow-covered sea ice is far higher than that of sea water. Sea water absorbs more solar radiation than would the same surface covered with reflective snow. When sea ice melts, either due to a rise in sea temperature or in response to increased solar radiation from above ...
