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 ...
For example, in duodecimal, 1 / 2 = 0.6, 1 / 3 = 0.4, 1 / 4 = 0.3 and 1 / 6 = 0.2 all terminate; 1 / 5 = 0. 2497 repeats with period length 4, in contrast with the equivalent decimal expansion of 0.2; 1 / 7 = 0. 186A35 has period 6 in duodecimal, just as it does in decimal. If b is an integer base ...
In general, if an increase of x percent is followed by a decrease of x percent, and the initial amount was p, the final amount is p (1 + 0.01 x)(1 − 0.01 x) = p (1 − (0.01 x) 2); hence the net change is an overall decrease by x percent of x percent (the square of the original percent change when expressed as a decimal number).
The smallest non-abelian group is the symmetric group which has 3! = 6 elements. [1] 6 the answer to the two-dimensional kissing number problem. [15] A regular cube, with six faces. A cube has 6 faces. A tetrahedron has 6 edges. In four dimensions, there are a total of six convex regular polytopes.
The name "chi-square" ultimately derives from Pearson's shorthand for the exponent in a multivariate normal distribution with the Greek letter Chi, writing −½χ 2 for what would appear in modern notation as −½x T Σ −1 x (Σ being the covariance matrix). [26]
16.93 ± 0.01 [7] · 17.02 [5] [6] · 17.5 [1 (52760) 1998 ML 14 ( provisional designation 1998 ML 14 ) is a stony asteroid , classified as near-Earth object of the Apollo group and potentially hazardous asteroid , approximately 1 kilometer in diameter.
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 ]
There were 9,820 housing units at an average density of 16 per square mile (6/km 2).
