The range is the interval of y values.
Smallest y values is -9 and the highest y values is 9.
So the range is
Answer:

Step-by-step explanation:
First, we open the parentheses by multiplying the contents of the parentheses by 3 (because it says 3(2x+6)). The final result is <u>6x+18</u>
Answer:

y=10
Step-by-step explanation:
Properties of rectangle:
- Opposite sides are congruent
- All angles are right angles
- Diagonals bisect each other
- Diagonals are of equal length
so from the properties we came to know that diagonals bisects each other and diagonals are of equal length
Given Rectangle RSUT has diagonals that meet at point X.

Option A is correct.
For testing, if x is a significant predictor of y in simple linear regression, we need to determine if the <u>slope </u><u>is </u><u>significantly different </u><u>from</u><u> zero</u>.
What is linear regression?
A statistical technique known as linear regression is used to represent the connection between a scalar answer and one or more explanatory factors. When there is just one explanatory variable, simple linear regression is employed; when there are numerous explanatory variables, multiple linear regression is utilized.
Based on the value of another variable, linear regression analysis makes predictions about the value of the first variable. The dependent variable is the one you're trying to forecast. The independent variable is the one you are utilizing to make a prediction about the value of the other variable.
