Answer:
-0.924
Step-by-step explanation:
The magnitude of the correlation coefficient is the square root of the variation.
|r| = √0.854
|r| = 0.924
The sign of the correlation coefficient is the same as the slope of the line of best fit. In this case, it's negative.
r = -0.924
There are 180 degrees total in a triangle and the tell you one angle is 90. So you solve the equation 4x+6x=90. So x=9
Answer:
See below
Step-by-step explanation:
If by circumference you meant perimeter and diameter you mean length, then here is my answer.
Perimeter = 2L+ 2W
13653= 2*L + 2*5431
13653= 2L + 10862 Subtract 10862 from both sides
2791= 2L Divide by 2
L= 1395.5
The diameter is 1395.5
