The correlation coefficient r of the data set is <em>-0.28</em>
Answer:
A. 45.7
Step-by-step explanation:
Side a = 8
Side b = 7.8
Side c = 11.17318
Angle ∠A = 45.725° = 45°43'31" = 0.79806 rad
Angle ∠B = 44.275° = 44°16'29" = 0.77274 rad
Angle ∠C = 90° = 1.5708 rad = π/2
Answer:
w > -1
Step-by-step explanation:
Hello There!
We want to simplify this expression to be more specific we want to isolate the variable (w) using inverse operations
So we want to get rid of the 8 in 8w
8w is the same as 8 times w (multiplication)
The inverse of multiplication is division so to get rid of the 8 we want to divide by 8 but remember whatever we do to one side we want to do to the other side. So we divide each side by 8
-8/8 = - 1
8w/8=w
we're left with w > -1
