Answer:

<h2>(1, -2)</h2>

Step-by-step explanation:

Notice that coordinates (1,3) and (1,-2) have different images for the same x-value, that means the set of pairs doesn't represent a function, it's just a relation between two sets.

Remember that a function can't have two different images for one domain element.

Therefore, we can remove (1,-2) in order to have a function.

Sholpan [36]

Complete question :

En un concesionario de coches hay modelos de varios colores. Los rojos suponen 1/6 del total, los azules, 2/9 del total, y los blancos, 4/15 del total.

a)¿Cuál de esos colores es el más frecuente?

b) Si hay 40 coches azules, ¿cuántos hay en total?

Responder:

Coches blancos

180 coches

Explicación paso a paso:

Dado que:

Rojo = 1/6 del total

Azul = 2/9 del total

Blanco = 4/15 del total

Para determinar qué color es el más alto, convierta los valores en decimal:

1/6 = 0,166667

2/9 = 0,2222

15/4 = 0,26667

Por lo tanto;

4/15> 2/9> 1/6

Por tanto, los coches blancos son los que más

2.)

Sea Número total = x

Por lo tanto,

2/9 de x = 40

2x / 9 = 40

2x = 360

x = 180

Por tanto, hay 180 coches en total.

Simplify 59.95m − 30 + 7.95m + 45 + 9.49m
Ksju [112]

Answer:

77.39m + 15

Step-by-step explanation:

To simplify, we add all the common terms among themselves.

We have terms with the unit m and terms without any unit. So we add them among themselves.

59.95m − 30 + 7.95m + 45 + 9.49m

(59.95 + 7.95 + 9.49)m + (-30 + 45)

77.39m + 15

n = (1.96 / .200)^2
n = 96.04  
Which is rounded Up to 97
The number of observations within the data set must be greater than or equal to the quantity of 97.
