Anit [1.1K]3 years ago

Answer:

The answer would be A. (1, -2)

Step-by-step explanation:

I made a graph, the rise is y, which is 2, when it is just one number and not a fraction you put a 1 on the bottom, so it would be 2/1, that is the slope. -4 is the y intercept, so you start at (0, -4) on the graph and go forward 1, and up 2. keep doing that and put dots as you go. One of the dots will be at (1,-2).

Oliga [24]

Answer:

First five terms are:

8 , (-4) , 2 , (-1) , (1/2)

Step-by-step explanation:

a_{1}=8 \\\\r = \frac{-1}{2}\\\\a_{2}=\frac{-1}{2}*a_{1}= \frac{-1}{2}*8= -4\\\\a_{3}=\frac{-1}{2}*a_{2}=\frac{-1}{2}*-4=2\\\\a_{4}=\frac{-1}{2}*a_{3}=\frac{-1}{2}*2=-1\\\\a_{5}=\frac{-1}{2}*a_{4}=\frac{-1}{2}*-1=\frac{1}{2}

En un estudio estadistico se van a usar unicamente variables cuantitativas discretas para ingresarlas a un programa de analisis
notka56 [123]

Answer:

la variable que se debe ingresar en el programa corresponde a: c. edad

Step-by-step explanation:

Las variables cuantitativas son aquellas que toman valores numéricos y se clasifican en variables cuantitativas discretas que son las que sólo pueden asumir un número limitado de valores en un determinado rango, como por ejemplo, el número de carros que posee una persona y variables cuantitativas continuas que pueden tomar cualquier valor en un rango específico, como por ejemplo, el peso de un objeto. De acuerdo a estas definiciones, la respuesta es que la variable que se debe ingresar en el programa corresponde a: edad porque es una variable discreta dado que se registra en números enteros y no acepta cualquier valor en un intervalo específico.

Las otras opciones no son correctas porque la nacionalidad y el nivel de escolaridad no son variables cuantitativas y la altura es una variable cuantitativa continua.

If Charlotte spent 25% more on furniture than she will on flooring, how much did she spend on furniture?
SashulF [63]

Answer:

Charlotte spent   x + 0.25x on furniture

Step-by-step explanation:

Given:

Charlotte spent 25% more on furniture than she will on flooring

To Find:

Amount spent on furniture = ?

Solution:

Let the amount spent on flooring be x

and the amount spent on furniture be y

25% more on furniture than she spent on flooring can be written as

=>25% of x

So the cost spent on furniture will be

=>y= cost spent on flooring +  25% of cost spent on flooring

=>y= x + 25% of x

=>y=x + \frac{25}{100} \times x

=> y=x + 0.25x
