Answer:
The chip has no memory so the probability is just 1/2.
Answer:

Step-by-step explanation:
When x = 3, y = 13
When x = 5, y = 37
Subtract both y-values to find the change:
37 - 13 = 24
Average of the change:
= 12
-0.5,-0.4,-0.3,-0.1,0,1,2,3,4,4.17
9x+3x=180 by def. of supplementary
12x=180
12/12x=180/12
x=15
9x=9(15)=135°
