Zero matrix (p. 758) The zero matrix O, or o sub m times n end sub . comma is the m times n matrix whose elements are all zeros. It is the additive identity matrix for the set of all m times n matrices.

Matriz cero (p. 758) La matriz cero, O, o o sub m times n end sub . comma es la matriz m times n cuyos elementos son todos ceros. Es la matriz de identidad aditiva para el conjunto de todas las matrices m times n .

Zero of a function (p. 226) A zero of a function f open x close is any value of x for which f open x close equals 0 .

Cero de una función (p. 226) Un cero de una función f open x close es cualquier valor de x para el cual f open x close equals 0 .
Example A zero of a function. A w-shaped curve falls through (negative 1, 0) to a valley and rises through the origin at (0, 0), and then rises to a peak and then falls to a valley at (3, 0), and then rises through quadrant 1. All values are approximate.

Zero-Product Property (p. 226) If the product of two or more factors is zero, then one of the factors must be zero.

Propiedad del cero del producto (p. 226) Si el producto de dos o más factores es cero, entonces uno de los factores debe ser cero.

z-score (p. 740) The z-score of a value is the number of standard deviations that the value is from the mean.

Puntaje z (p. 740) El puntaje z de un valor es el número de desviaciones normales que tiene ese valor de la media.
