7x9 = 63
63x2 = 126
126 is the surface area
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
Answer:
p > -6
Step-by-step explanation:
1) Add 12 to both sides.
p > -18 + 12
2) Simplify -18 + 12 to -6.
p > -6
