Answer:
D. 1.25
Step-by-step explanation:
The values of the correlation coefficient must be between -1 and 1 (they can include -1 and 1)
The only value outside that range is 1.25
1.25 is not a possible correlation coefficient
Answer: Slope is -2
Step-by-step explanation:
Y² - Y¹ divide by X² - X¹
= 1 - 5 divide by 5 - 3
= -4/2
Slope is -2
(x1, y1) = (3,8)
(x2, y2) = (1,0)
If it's a rhombus, then the diagonals are equal.
Answer:
x = 10
Step-by-step explanation:
108 = (5x + 47) + (2x + 63)
5x + 47 + 2x + 63 = 180
Simplify
7x + 110 = 180
Move all terms not containing x to the right side of the equation.
7x = 70
Divide
x = 10
