The correct answer is -15 because the absolute value is 15 but there is a negative outside the absolute value lines making it negative :)
Answer:
Explained below.
Step-by-step explanation:
Consider the variables height and weight.
It is usually seen that taller people are heavier than shorter people.
So a regression analysis can be used to specify this belief.
The statistical questions that are being asked here are:
- What the independent and dependent variables?
- Are there any other factor influencing the dependent variable other than the independent variable?
The variable <em>Y</em> is considered as the dependent variable and the variable <em>Y</em> is considered as the independent variable. And the main purpose of the regression analysis is to predict the value of <em>Y</em> when the value of <em>X</em> is given.
The linear regression model can be used to predict the past and future value of the dependent variables provided that the independent variables for those times are provided.
(-4,-2)
You just plug in the numbers from the ordered pair, into your equation. Remember, the formula for ordered pairs are (x,y). :)
Answer:
The following expression can be used to represent the perimeter of rectangle ABCD: 16x-12
Step-by-step explanation:
Let l be the length of rectangle and w be the width of rectangle.
Given that:
The perimeter of a rectangle is given by the expression:
Putting the values of length and width, we get
Hence,
The following expression can be used to represent the perimeter of rectangle ABCD: 16x-12
