Midpoint (p. 114) The point M that divides a segment AB

into two equal segments, AM and MB.

Punto medio (p. 114) El punto M que divide un segmento

AB en dos segmentos iguales, AMy MB.

Example M is the midpoint of XY.

M Y

Midpoint Formula (p. 114) The midpoint M of a line

segment with endpoints A(x-|, y-|) and B(x2, y2) is

*1 + *2 yi + Yi

2 ' 2

Formula del punto m edio (p. 114) El punt o medi o M de

un segmento con puntos extremos A(xv y-|) y fi(x2, Yi) es

x, +x2 yr +y2'

2 ' 2

Example The midpoint of a segment with

endpoints A{3, 5) and 6(7, 1)

is (5, 3).

Minimum (p. 547) The y-coordinate of the vertex of a

parabola that opens upward.

Example

Minimo (p. 547) La coordenada y del vertice en una

parabola que se abre hacia arriba.

\ 1 yf

J

X

0

L

Since the parabola opens upward,

the y-coordinate of the vertex is

the function's minimum value.

Mode (p. 738) The mode is the most frequently occurring Moda (p. 738) La moda es el valor o valores que ocurren

value (or values) in a set of data. A data set may have no con mayor frequencia en un conjunto de datos. El conjunto

mode, one mode, or more than one mode. de datos puede no tener moda, o tener una o mas modas.

Example In the data set 7, 7, 9, 10, 11, and

13, the mode is 7.

Monomial (p. 486) A real number, a variable, or a product Monomio (p. 486) Numero real, variable o el producto de

of a real number and one or more variables with whole- un numero real y una o mas variables con numeros enteros

number exponents. como exponentes.

Example 9, n, and -5xy 2 are examples of

monomials.

Multiplication Counting Principle (p. 763) If there are Principio de Conteo en la Multiplicacion (p. 763) Si hay

m ways to make the first selection and n ways to make the m maneras de hacer la primera seleccion y n maneras de

second selection, then there are m n ways to make the hacer la segunda seleccion, quiere decir que hay m n

two selections. maneras de hacer las dos selecciones.

Example For 5 shirts and 8 pairs of shorts,
