La media aritmética de los siguientes datos son respectivamente: 1, 4, 1, 1, 4, 2, 3, 1, 4, 2Respuesta necesaria. Opción única.

AlekseyPX

Answer:

La media aritmética es 2.3

Step-by-step explanation:

Average o Promedio

El promerio, average, o valor medio es un valor representativo de un conjunto de datos y se calcula según la fórmula:

$\displaystyle \bar x=\frac{\sum x_i}{n}$

Donde xi es el valor de cada dato, y n es el número de datos.

Los datos presentados son:

1, 4, 1, 1, 4, 2, 3, 1, 4, 2

Nótese que hay un total de n=10 datos. Aplicamos la fórmula recordando que el símbolo Σ significa sumatoria:

$\displaystyle \bar x=\frac{1+ 4+ 1+ 1+ 4+ 2+ 3+ 1+ 4+ 2}{10}$

$\displaystyle \bar x=\frac{23}{10}=2.3$

La media aritmética es 2.3

4. Find the center and radius of the circle with equation x2 + y2-2x + 4y - 11 = 0

Solnce55 [7]

Answer:

x^2+y^ 2+2x-4y-11=0

x^2 + 2x + ? +y^2 - 4y + $ = 11 + ? + $

x^2 + 2x + 1 + y^2 - 4y + 4 = 11 + 1 + 4

(x + 1)^2 + (y - 2)^2 = 16

(x - - 1)^2 + (y - 2)^2 = 4^2

Center (-1,2) and radius = 4 (see bold in line above)
