Reflection line of reflection y=2
Not too sure could be rotation maybe
Since the value is taken from a population, the value is a parameter.
<h3>Parameter and Statistic:</h3>
- If the information is taken from a sample, it is called a statistic.
- If the information is taken from a population, it is called a parameter.
For this problem, the students of the class are the population, as all students are considered for the calculator of the mean, hence the value is a parameter.

Answer:
D
Step-by-step explanation:
In this question we are asked to pick the correct option that clearly states what statisticians use linear regression for.
To answer this question, I shall be considering the validity of the options one after the other.
But before that , what is a linear regression model?
A linear regression model employs a linear plot to explain the relationship between a dependent variable and another variable called the independent variable.
Option a is wrong.
A regression model does not say if the dependent and independent variables match
Option B is wrong
A linear regression model cannot be used to predict the value of an unknown dependent variable from the unknown Independent variables. X is the independent here with y the dependent
Option C is wrong
Since Y scores is known, then what are we predicting again?
Option. D is correct
We predict values of the unknown dependent variable y from the known independent variable x
The answer is 30
2/3=.666
*18=12
12+18=30
