When you graph the three lines, the first two overlap. The third is parallel to those two.
Answer:
A: The correlation coefficient is a statistical measure of the strength of the relationship between the relative movements of two variables. The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement.
B: he correlation coefficient is a statistical calculation that is used to examine the relationship between two sets of data. The value of the correlation coefficient tells us about the strength and the nature of the relationship. Correlation coefficient values can range between +1.00 to -1.00.

Hopefully this helped!!!
That solid figure that you are is a square.
Area of a rectangle is

(7.4×5.5)m
=40.7m
therefore the area of the room is 40.7m
<em>Note: your equation is a little bit unclear. Thus, I am assuming that
</em>
<em>y = 2x+5</em>
<em>
Anyway, the procedure remains the same. It would anyways clear your concept.</em>
Answer:
We conclude that the ordered pair (2, 1) is a solution.
Step-by-step explanation:
Given the equation

Check for point (2, 1)
substituting the point (2, 1) in the equation to check whether the ordered point satisfies the equation or not.

plug in x = 2 and y = 1
1 = -2(2)+5
1 = -4+5
1 = 1
R.H.S = L.H.S
TRUE
Therefore, the given ordered pairs satisifes the equation.
Hence, we conclude that the ordered pair (2, 1) is a solution.
