Answer:
The correct statement is (B).
Step-by-step explanation:
The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.
If there is any alteration in the value of one variable, the value of the other variable is altered in a fixed proportion. The correlation amid them is known as perfect correlation.
In statistics, a perfect positive correlation is represented by +1 and -1 indicates a perfect negative correlation.
Positive correlation is an association amid two variables in which both variables change in the same direction.
A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.
Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa.
A correlation coefficient of 0 implies that there is no relationship between the two variables.
Thus, the correct statement is (B).
We'll use elimination for this system of equations. What variable should get canceled? The x or y? Well to cancel, we need a positive and negative variable.
x + y = 10
x - y = 0
In this case, the y's will cancel out.
Then we will add the x's together and the 10 and 0.
x + y = 10
x - y = 0
Becomes
2x = 10
Now, solve for x. Just simply divide by 2.
2x / 2 = 10 / 2
x = 5
Now we know what the x variable is equal to!
To solve for the y variable, just replace the x variable in one of the equation and solve for y.
I'll use the x + y = 10 equation
We know x is equal to 5.
5 + y = 10
Subtract both sides by 5.
5 - 5 + y = 10 - 5
y = 5
So, both x and y are equal to 5.
