Which of the following do indexes and scales have in common?

statuscvo [17]

Answer:

c.They rank-order the units of analysis in terms of specific variables

Step-by-step explanation:

An index is a way of compiling one score from a variety of questions or statement that represents a belief, feeling or attitude.

Scales on the other hand measure levels of intensity at a variable level like how much a person agrees or disagrees with a particular statement.

The one thing common to both indexes and scales is that

They rank-order the units of analysis in terms of specific variables.

Given: Isosceles TriangleDEF. The measure of vertex Angle D is four times the measure of each base angle E and F.

777dan777 [17]

Answer:

D = 120° , E = 30° , F = 30°

Step-by-step explanation:

Let D = 4x

Let E&F = x

4x + x + × = 180°[angles in triangle is 180°]

6x = 180°

x = 180/6

x = 30°

E = 30°

F =30°

D =4(30°)

=120°

Question 6 of 10

Maksim231197 [3]

Answer:

(2.5 , 3.5)

Step-by-step explanation:

We can use the midpoint formula . Here the points are , (2,2) and (3,5) .

• Using Midpoint Formula :-

⇒ M = { (x1 + x2)/2 , (y1 + y2)/2 }

⇒ M = ( 2+3/2 , 5+2/2 )

⇒ M = ( 5/2 , 7/2 )

⇒ M = ( 2.5 , 3.5 )

<h3>Hence the midpoint is (2.5 , 3.5)</h3>

Fiona y sus amigas fueron a una tienda de batidos. Pidieron tres batidos de fresa y dos batidos de proteínas por un total de $ 2

Answer:

Un batido de proteínas cuesta $ 5,25.

Step-by-step explanation:

El sistema de ecuaciones descrito al final del enunciado coincide con lo descrito al comienzo del mismo, de modo que podemos concentraron casi exclusivamente en la resolución del sistema en cuestión, la cual se describe a continuación:

Este es el sistema a resolver:

$x + 4\cdot y = 25,50$ (1)

$3\cdot x + 2\cdot y = 24,00$ (2)

Donde $x$ es el coste de un batido de fresa y $y$ corresponde al coste de un batido de proteínas:

1) Despejamos $x$ en (1):

$x = 25,50 - 4\cdot y$

2) Eliminamos $x$ en (2):

$3\cdot (25,50 - 4\cdot y) + 2\cdot y = 24,00$

$76,50 - 12\cdot y +2\cdot y = 24,00$

3) Simplificamos y despejamos $y$ :

$10\cdot y = 52,50$

$y = 5,25$

Un batido de proteínas cuesta $ 5,25.
