We know that college GPA is positively correlated with salary after college. If we use knowledge of a student's GPA to predict h
anygoal [31]

Answer:

Step-by-step explanation:

Given that college GPA is positively correlated with salary after college

This means there is a positive linear relationship between GPA and salary after college.

Or we can write one as dependent and another as independent.

Since in the given question Salary is to be found out for given GPA we can make GPA as independent variable and Salary after college dependent variable

We will find a linear relationship as

Salary = slope * GPA + intercept

So

If we use knowledge of a student's GPA to predict his or her salary, the criterion variable is __GPA_____ and the predictor variable is __Salary after college._____.

Find the coordinates of the focus and equation of the directrix for the parabola given by
Romashka [77]

Answer:

The answers to your three problem question are shown

1) the value of p is

p = -1

2) The coordinates of the focus are

Focus =  (-1,0)

3) The equation of the directrix is

Directrix

x = 1

Step-by-step explanation:

The general equation for this parabola is

y^2 = 4px

Problem 1

Find the value of p.

We are told that the equation of the problem is

y^2 = -4x

And the general formula is

y^2 = 4px

From there, we can deduce that

p = -1, because

y^2 = 4(-1)x = -4x

This means that p = -1

Problem 2

Find the focus

To find the focus we can see the equations attached below for the focus, vertex and directrix.

In these case, the equations still apply, even though the variable is inverted, we just need to adjust it

y^2 = -4x =>

x = (-1/4)*y^2

x = a*y^2 + b*y +c

Focus

((4ac -b^2  + 1)/4a, -b/2a)

But, b = 0 and c = 0

=>

(1/4a,0) = (1/4(-1/4),0) = (-1,0)

Focus =  (-1,0)

Problem 3

Find the directrix

The equation is

x = c - (b^2 + 1).4a

But, b = 0 and c = 0

x = -4*a

x = -4* (-1/4) = 1

x = 1

Directrix

x = 1
