In mathematics, "rational" is often used as a noun abbreviating "rational number". The adjective rational sometimes means that the coefficients are rational numbers. For example, a rational point is a point with rational coordinates (i.e., a point whose coordinates are rational numbers); a rational matrix is a matrix of rational numbers; a rational polynomial may be a polynomial with rational ...
The percent value can also be found by multiplying first instead of later, so in this example, the 50 would be multiplied by 100 to give 5,000, and this result would be divided by 1,250 to give 4%. To calculate a percentage of a percentage, convert both percentages to fractions of 100, or to decimals, and multiply them. For example, 50% of 40% is:
The number of millilitres of pure ethanol is the mass of the ethanol divided by its density at 20 °C (68 °F), which is 0.78945 g/mL (0.82353 oz/US fl oz; 0.79122 oz/imp fl oz; 0.45633 oz/cu in). [4] The alc/vol standard is used worldwide.
Four fours is a mathematical puzzle, the goal of which is to find the simplest mathematical expression for every whole number from 0 to some maximum, using only common mathematical symbols and the digit four.
0.4, .4, point four, or dot four may refer to: . The number 0.4 as a fractional number; 0.4 shot, a basketball shot made by player Derek Fisher with 0.4 seconds left in Game 5 of the NBA 2004 Western Conference Semifinals
In binary arithmetic, the idea is to round the result toward zero, and set the least significant bit to 1 if the rounded result is inexact; this rounding is called sticky rounding. [20] Equivalently, it consists in returning the intermediate result when it is exactly representable, and the nearest floating-point number with an odd significand ...
The model is most accurate when used to estimate BAC a few hours after drinking a single dose of alcohol in a fasted state, and can be within 20% CV of the true value. [ 27 ] [ 28 ] It is not at all realistic for the absorption phase, and is not accurate for BAC levels below 0.2 g/L (alcohol is not eliminated as quickly as predicted) and ...
According to rules of thumb, this approximation is good if n ≥ 20 and p ≤ 0.05 [36] such that np ≤ 1, or if n > 50 and p < 0.1 such that np < 5, [37] or if n ≥ 100 and np ≤ 10. [38] [39] Concerning the accuracy of Poisson approximation, see Novak, [40] ch. 4, and references therein.
