Answer:

The predictor variable is the number of hours spent studying for a test.

The response variable is the grades on a test.

Step-by-step explanation:

Linear regression depicts the relationship between two variables by fitting a linear equation to experimental data values. One variable is known as an predictor (independent) variable, and the other is known as a response (dependent) variable.

The general form of a linear regression line is,

\hat Y = a + bX

Here,

<em>X</em> = predictor variable

Y = response variable.

The variable <em>b</em> = slope of the line, and <em>a</em> = intercept (the value of y when x = 0).

The main purpose of forming a regression line is to estimate or predict the value of the response variable for different values of the predictor variables.

The predictor variable is changes to observe the changes in the response variable.

In this case the college counselor wants to determine if the number of hours spent studying for a test can be used to predict the grades on a test.

The predictor variable is the number of hours spent studying for a test.

The response variable is the grades on a test.

Because the counselor is using the number of hours studied to estimate the marks obtained.

In rectangle KLMN, KM = 10x+24 and KN = 64 find x
pishuonlain [190]
Hi there, I don't know if I am right but I will try to solve this, 10x+24=64, subtract 24 from both sides, 10x+24-24=64-24=10x=40, divide both sides by 10, 10x/10=40/10, x=4

After college graduation, Mario received employment offers from two companies. The first company offered a yearly salary of $31,
Alexandra [31]
The first thing we must do for this case is to define a variable:
 x: number of years
 y: total salary
 We have then:
 For first company:
 y = 1500x + 31000
 For second company:
 y = 2000x + 28500
 Equaling both equations we have:
 1500x + 31000 = 2000x + 28500
 Clearing x:
 2000x - 1500x = 31000 - 28500
 500x = 2500
 x = 2500/500
 x = 5
 Answer:
 
It will take for the salaries to be the same about:
 
x = 5 years
