The correlation coefficient between two variables, r, is always going to be between -1 and 1.
- If the correlation coefficient is 0, means that there is no strong correlation relationship in one direction or the other direction.
- If the correlation coefficient is -1, means that these two variables move in opposite directions.
- If the correlation coefficient is 1, means that these two variables move in the same direction.
Answer: 5
The Distance between the coordinates of two points is measured by distance formula.
Step-by-step explanation:
The Distance between the coordinates of two points P(x1,y1) and Q(x2,y2) is measured by
Distance PQ= 
(x2-x1)²+(y2-y1)²
So, the distance between (-1,4 ) and (2,0) can be calculated by
Distance= (2-(-1))²+(0-4)²
= (3)²+(-4)²
=9+16 = 25 as 25 = 5
Distance = 5
So the distance between the two coordinates is 5.

Answer:
Your answer is B.
Step-by-step explanation:
So you do 3x+5x-10 (cuz your multiplying) then you add the x which is 3x+5x you get 8x-10
Answer:
84 ft^2
Step-by-step explanation:
Rectangle 1: Area = l x w = 3x6=16
Rectangle 2: 4x6= 24
Rectangle 3: 5x6=30
Triangle 1: A = 1/2 b x h = 1/2 x 4 x 3 = 6
Triangle 2: 1/2 x 4 x 3 = 6
Total = 16+24+30+6+6 = 84
