Yes, but what does that mean, you need to give some context so that people can answer. I'll guess what it means.

this is the answer to this question - Two weather tracking stations are on the equator 146 miles apart. A weather balloon is located on a bearing of N 35°E from the western station and on a bearing of N 23°E from the eastern station. How far is the balloon from the western station?

Answer:

Reasons:

The given parameters are;

Distance between the two stations = 146 miles

Location of the weather balloon from the Western station = N35°E

Location of the weather balloon from the Eastern station = N23°E

The location of the station = On the equator

Required:

The distance of the balloon from the Western station

Solution:

- The angle formed between the horizontal, and the line from the Western station

to the balloon = 90° - 35° = 55°

- The angle formed between the horizontal, and the line from the Eastern station

to the balloon = 90° + 23° = 113°

The angle at the vertex of the triangle formed by the balloon and the two stations is 180° - (55 + 113)° = 12°

By sine rule,

Distance from balloon to western station = 146/sin(12 dg) = Distance from balloon to western station/sin(113 dg)

Therefore;

Distance from balloon to western station = 146/sin(12 dg) x sin(113 dg) ~ 646.4

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.
