What is the formula for finding mean or average?​

Mathematics

Answer:

LOOK BELOW

Step-by-step explanation:

I would not call the explanation a formula

All you have to do to solve mean or average is add all of the numbers up and divide by the total amount of numbers

so for example

0,2,4,0,2,3,2,8,6  <-------- lets find the mean/average

0+2+4+2+3+2+8+6= 27/amount of numbers

amount of numbers=9

(count the zeros too!)

27/9=3

3 is the mean or average!!!

Calcule la ecuación general de la recta que pasa por la intersección de la recta:
adell [148]

La ecuación general de la recta es x + 3 · y = - 15.

<h3>¿Cómo determinar la ecuación de una recta?</h3>

Según la geometría, una recta es generada por la existencia de dos puntos distintos y en este problema debemos hallar una ecuación de la recta que pasa por la intersección de las dos rectas y otro punto. Primero, determinamos la solución del sistema de ecuaciones lineales para conocer la localización del primer punto:

7 · x - 15 · y = 39                 (1)

5 · x + y = - 19                     (2)

The solución del sistema de ecuaciones lineales is (x, y) = (- 3, - 4).

Segundo, determinamos la pendiente de la recta mediante la fórmula de la recta secante:

m = [- 6 - (- 4)] / [3 - (- 3)]

m = - 1 / 3

Tercero, determinamos el intercepto a partir de la ecuación de la recta:

b = y - m · x

b = - 6 - (- 1 / 3) · 3

b = - 6 + 1

b = - 5

Finalmente, determinamos la ecuación de la recta en su forma general:

y = (- 1 / 3) · x - 5

(1 / 3) · x + y = - 5

x + 3 · y = - 15

La ecuación general de la recta es x + 3 · y = - 15.
