Answer:
Step-by-step explanation:
angle:: x
complemet: 90-x
supplement: 180-x
Equation:
180-x = 4(90-x)+60
180-x = 360 -4x + 60
3x = 240
x = 80 degrees (the angle)
90-x = 10 degrees (the complement)
180-x = 100 degrees (the supplement)
Variable A - horizontal axis ⇒ x
Variable B - vertical axis ⇒ y
points (x, y)
A B
1) 2 , 2
2) 2 , 8
3) 4 , 3
4) 5 , 1
5) 6 , 3
6) 7 , 5
7) 8 , 6
8) 9 , 2
Mean of Variable A.
(2 + 2 + 4 + 5 + 6 + 7 + 8 + 9) ÷ 8 = 43 ÷ 8 = 5.375 OR 5.40
Mean is the average value of the data set. Add all the numbers in the data set and divide its sum by its count.
