Standard-definition television (SDTV; also standard definition or SD) is a television system that uses a resolution that is not considered to be either high or enhanced definition. [1] Standard refers to offering a similar resolution to the analog broadcast systems used when it was introduced.
The SD specification defines a card called Thin SD with a thickness of 1.4 mm, [citation needed] but they occur only rarely, as the SDA went on to define even smaller form factors. The card's electrical contacts are recessed beneath the surface of the card, protecting them from contact with a user's fingers.
In a fraction, the number of equal parts being described is the numerator (from Latin: numerātor, "counter" or "numberer"), and the type or variety of the parts is the denominator (from Latin: dēnōminātor, "thing that names or designates").

Example of samples from two populations with the same mean but different standard deviations. Red population has mean 100 and SD 10; blue population has mean 100 and SD 50. A large standard deviation indicates that the data points can spread far from the mean and a small standard deviation indicates that they are clustered closely around the mean.
In algebra, the partial fraction decomposition or partial fraction expansion of a rational fraction (that is, a fraction such that the numerator and the denominator are both polynomials) is an operation that consists of expressing the fraction as a sum of a polynomial (possibly zero) and one or several fractions with a simpler denominator.
Sesame Street was conceived in 1966 during discussions between television producer Joan Ganz Cooney and Carnegie Foundation vice president Lloyd Morrisett.Their goal was to create a children's television show that would "master the addictive qualities of television and do something good with them," [16] such as helping young children prepare for school.
