Answer: Option A is correct.
Step-by-step explanation:
- The correlation coefficient(r) is a statistical measure that computes the strength of the relationship between two variables.
It lies between -1 and 1.
If the correlation coefficient in an ordinary least squares regression = 1.00.
That indicates that there is a perfect relationship between the variables.
i.e. all the data points must fall exactly on a straight line with a positive slope. .
[when r is positive, the slope of the line is positive].
i.e. option A is correct.
Answer:
Three or more points that lie on the same line are collinear points .
Step-by-step explanation:
Answer:
x < -5/3 + b
Step-by-step explanation:
Step 1: Write inequality
-3x + 3b > 5
Step 2: Solve for <em>x</em>
<u>Subtract 3b on both sides:</u> -3x > 5 - 3b
<u>Divide both sides by -3:</u> x < -5/3 + b
Step-by-step explanation:
1. yes 4+16 = 20
2. yes 32 - 4 = 28
3. yes 4(10) = 40
4. no 24/6 = 4
Answer:
2/18, 1/9
Step-by-step explanation:
5/18 + (-1/6)
-1/6=-3/18
5/18+(-3/18)=
2/18
