Answer:
The Z is has no lines of symmetry. The W and Y have one line of symmetry. The X has two lines of symmetry.
The graph is shown below. I used GeoGebra to create the graph. The graph is restricted on the domain 
meaning that everything to the left of x = 0 is not drawn, and the same for everything to the right of x = 2.
A table of values is included as well. Each row in the table represents an ordered pair point (x,y) that is on the blue cosine graph.
Answer:
11/12
Step-by-step explanation:
7/6= 14/12
8/6= 16/12
the number in between the two is 15/12 then it already shows you what to subtract by (4/12) so 15/12-4/12=11/12
P(rolling a 5) = 1/6
P(rolling a 1) = 1/6
P(rolling a 1 or a 5) = (1/6 ) + (1/6) = 1/3
The answer is 1/3
