The slope of any line perpendicular to , where A(0, -3) and B(4, 9) are two points on the line, is m =
enyata [817]

Answer:

m = -1/3

Step-by-step explanation:

The slope of the line can be calculated using the slope formula.

m = \frac{y_2-y_1}{x_2-x_1} = \frac{9--3}{4-0} = \frac{12}{4} = 3

Since this is the line with points AB, the slope of any line perpendicular to it will be -1/3. All perpendicular lines cross at a 90 degree angle and as such their slopes are the negative reciprocals of each other. This means 3 becomes -1/3.

Los alumnos de 6 grado obtuvieron las siguientes calificaciones en sus exámenes de matemáticas, encuentra la Media, moda y media
skelet666 [1.2K]

Answer:

Media = 8.73

Moda = 9.0

Mediana = 9.0

Step-by-step explanation:

En este caso, vamos a repasar primero el concepto de cada uno:

Media: Se refiere a un promedio numérico de varios datos en una medida. Se calcula como la sumatoria de todos los valores numéricos dividido entre la cantidad de valores existentes,

Moda: Se refiere al valor numérico que mas se repite en una secuencia numérica.

Mediana: Se refiere al número, o números, que se encuentran justo en la mitad de una secuencia numérica ordenada de menor a mayor o de mayor a menor.

Tomando en cuenta estos conceptos, determinemos cada uno de ellos. Son 15 calificaciones. Si las ordenamos todas de menor a mayor tenemos:

7.0, 8.0, 8.0, 8.0, 8.0, 9.0, 9.0, 9.0, 9.0, 9.0, 9.0, 9.0, 9.0, 10.0, 10.0

Para la media:

Media = 7 + (8+8+8+8) + (9+9+9+9+9+9+9+9) + (10+10) / 15

<h2>Media = 8.73</h2>

<u>Para la moda:</u>

Como se puede observar, la calificación 9.0 se repitió 8 veces por lo tanto

<h2>Moda = 9.0</h2>

<u>Para la mediana:</u>

Al observar los datos ordenados de mayor a menor, nos damos cuenta que la calificación 9.0 se encuentra en la mitad de esos datos, asi que

<h2>Mediana = 9.0</h2>

Espero te ayude.
