Correct answer is : Area of triangle is 
Solution:-
We can do it in 2 methods.
Method 1:-
Given that AB=6, BC=10 and m∠B = 120
Then area of triangle = 
Let us assume AB is base and D is an altitude from C onto AB.
Then sin(60)= 
CD = BC sin(60)
Hence height = 
= 
Hence area of ΔABC = 
sq.units
Method2:-
Area of triangle = 
Here a= BC=10, c=AB=6.
Hence area of triangle = 
sq.units
D is subset of Z, so D∩Z=D. hope it helps.
Answer:
The residual value is the difference between the observed value (from the scatter plot) and the predicted value (from the line of best fit).
Step-by-step explanation:
The residual value is the difference between the observed value (from the scatter plot) and the predicted value (from the line of best fit).
Residual Value = Observed Value - Predicted Value
<em>Since the residual value of -4.5 is negative, we can say the predicted value is larger than the observed value. In other words, the line of best fit is "above" the scatter plot point in that specific point.</em>
