All 128 ASCII characters, including non-printable characters ( represented by their abbreviations ). The 95 ASCII graphic characters are numbered from 20 < sub > hexadecimal | hex </ sub > to 7E < sub > hexadecimal | hex </ sub > ( decimal 32 to 126 ).

The " space " character had to come before graphics to make sorting easier, so it became position 20 < sub > hex </ sub >; for the same reason, many special signs commonly used as separators were placed before digits.

To keep options available for lower case letters and other graphics, the special and numeric codes were arranged before the letters, and the letter " A " was placed in position 41 < sub > hex </ sub > to match the draft of the corresponding British standard.

The @ symbol was not used in continental Europe and the committee expected it would be replaced by an accented À in the French variation, so the @ was placed in position 40 < sub > hex </ sub > next to the letter A.

* If it is required to use a single number X as an estimate for the value of numbers, then the arithmetic mean does this best, in the sense of minimizing the sum of squares ( x < sub > i </ sub > − X )< sup > 2 </ sup > of the residuals.

Algeria has always been a source of inspiration for different painters who tried to immortalize the prodigious diversity of the sites it offers and the profusion of the facets that passes its population, which offers for Orientalists between the 19 < sup > th </ sup > century and the 20 < sup > th </ sup > century, a striking inspiration for a very rich artistic creation like Eugène Delacroix with his famous painting women of Algiers in their apartment or Etienne Dinet or other painters of world fame like Pablo Picasso with his painting women of Algiers, or painters issued from the Algiers school.

Only a limited number of actinium compounds are known including AcF < sub > 3 </ sub >, AcCl < sub > 3 </ sub >, AcBr < sub > 3 </ sub >, AcOF, AcOCl, AcOBr, Ac < sub > 2 </ sub > S < sub > 3 </ sub >, Ac < sub > 2 </ sub > O < sub > 3 </ sub > and AcPO < sub > 4 </ sub >.

Except for AcPO < sub > 4 </ sub >, they are all similar to the corresponding lanthanum compounds and contain actinium in the oxidation state + 3.

Next consider the sample ( 10 < sup > 8 </ sup > + 4, 10 < sup > 8 </ sup > + 7, 10 < sup > 8 </ sup > + 13, 10 < sup > 8 </ sup > + 16 ), which gives rise to the same estimated variance as the first sample.

Because the clocks had been on average well above sea level, this meant that TAI slowed down, by about 10 < sup >− 12 </ sup >.

He also offers a conversion table ( see Cohen, 1988, p. 283 ) for eta squared ( η < sup > 2 </ sup >) where 0. 0099 constitutes a small effect, 0. 0588 a medium effect and 0. 1379 a large effect.

When there are only two means to compare, the t-test and the ANOVA F-test are equivalent ; the relation between ANOVA and t is given by F = t < sup > 2 </ sup >.

The number of carbon atoms is used to define the size of the alkane ( e. g., C < sub > 2 </ sub >- alkane ).

Hydrochloric acid, sulfuric acid and nitric acid dissolve cadmium by forming cadmium chloride ( CdCl < sub > 2 </ sub >), cadmium sulfate ( CdSO < sub > 4 </ sub >), or cadmium nitrate ( Cd ( NO < sub > 3 </ sub >)< sub > 2 </ sub >).

The oxidation state + 1 can be reached by dissolving cadmium in a mixture of cadmium chloride and aluminium chloride, forming the Cd < sub > 2 </ sub >< sup > 2 +</ sup > cation, which is similar to the Hg < sub > 2 </ sub >< sup > 2 +</ sup > cation in mercury ( I ) chloride.
