<span>The correlation coefficient is a value that signifies correlation and dependence between two or more values. </span>The following statements are true:
- The correlation coefficient is a unitless number and must always lie between –1.0 and +1.0, inclusive.
- The correlation coefficient, r, gives us information about the strength and direction of a linear relationship between any two variables.
<span>- The larger r is in absolute value, the stronger the relationship is between the two variables.

that's a point slope form so
y +5 = 2(x -4)
Multiply both sides by (3*5)
5(2n)=3(n+14)
distribute
10n=3n+42
minus 3n both sides
7n=42
divide both sides by 7
n=6
Answer:
Step-by-step explanation:
Triangle equilateral has 3 sides
3(3x+2) = 60
9x+6 =60
9x= 54
x=9
3x9 +2 = 20 One side = 20
20x3=60 3 sides = 60
All sides are together. Basic question actually.
