Answer:
I believe C is the line of best fit because everything is spread out more evenly instead of some being spread out farther than others.
Answer:
x<-1
Step-by-step explanation:
All of the numbers on/in the set are below -1. That means for that any of them to be x, the inequality would be x<-1.

We know that, in ∆ABC,
∠A+∠B+∠C = 180°
But the triangle is right angled at C
ie., ∠C = 90°
Therefore, ∠A+∠B+ 90° = 180°
⇒ ∠A + ∠B = 90°
Therefore, <u>cos(A + B) = cos 90º = 0</u>
