Z= x - mean/SD so 12.2-14/1.2= -1.5

Z = (x - μ)/σ

Fill in the given information and do the arithmetic.
z = (12.2 -14)/1.2 = -1.8/1.2

z = -1.5

Why does the equation y=3x+5 Not represent a proportional relationship?

Afina-wow [57]

Answer:

see the explanation

Step-by-step explanation:

we now that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>

In this problem we have

$y=3x+5$

This is the equation of the line in slope intercept form

where

$m=3\\b=5$

The given equation not represent a proportional relationship, because the line not pass through the origin

In a proportional relationship the value of b (y-intercept) is equal to zero

Which of the following statements would be the process that is used to describe solving a system of equation with 6 variables?

Karolina [17]

I think the correct answer from the choices listed above is the second option. Solving a 6 order system <span>would be the process that is used to describe solving a system of equation with 6 variables. The number of variables should be equal to the order of the system for it to be solved. Hope this answers the question.</span>
