g Explain the difference between explanatory and response variables. Is it important to distinguish between the two in linear regression

Answers

Answer: See explanation

Step-by-step explanation:

The response variable is the variable that the researcher is interested in. It is what the experiment really focuses on.

An explanatory variable is the variable that is being manipulated by the researcher and it explains the variations that may occur to the response variable.

It should also be noted that it is important to distinguish between the response variable and the explanatory variable in a linear regression.

if f(x)=15x-7 then f^-1(x)

Answers

Hi!

So, we need to find the inverse of the function f(x) = 15x - 7.

To start, we must turn the f(x) into a y.

y = 15x - 7.

Now, we swap all the x variables for the y variables, and swap all the y variables for the x variables!

x = 15y - 7.

Now, we simply must work on isolating y. Assuming you know how to isolate a variable, we must do the steps below -

x = 15y - 7.

Add 7 on both sides.

x + 7 = 15y - 7 + 7.

We cannot add x and 7, as they are not like terms. So, they will remain like that, while the 7 on the right side of the equation is eliminated.

x + 7 = 15y.

Now we are going to divide both sides by 15, thus leaving y by itself.

= 15y / 15.

Since we cannot divide the left side of the equation by 15, it will remain as such. With the y variable completely isolated, our final inverse function will be:

= .

Hopefully, this helps! =)

Which equation represents the rectangular form of r = 8?

Answers

Answer:

x^2 + y^2 = 64

Step-by-step explanation:

EDGE 2020

The equation that represents the rectangular form of r = 8 is x² + y² = 64

What is rectangular form?

Rectangular form, is where a complex number is denoted by its respective horizontal and vertical components.

According to the given problem,

x=rcosθ

y=rsinθ

substituting we have

x=8cosθ

y=8sinθ

Squaring and adding we obtain the

circle's origin centered equation,

x² + y² = 64

Hence, we can conclude, the equation x² + y² = 64, represents the rectangular form of r = 8.

Write the equation of the line in slope-intercept form that goes through the points: (2, 4) and (7, -1) *

Answers

Answer:

1. slanting upward because the slope is positive one.

2. A: 3/4 B: 4/-3

3. A: 3 B: y=3x-10

1. (-2-7)/(-4-5) = -9/-9 = 1

2. A: (7-4)/(7-3) = 3/4

B: (8-0)/(-6-0) = 8/-6 = 4/-3

3. find the slope first so (4-1)/(2-1)= 3/1. then you plug in point C to find the y intercept so y=mx+b would be 2=3(4)+b which makes it so b is -10. the new equation would be y=3x-10
