y=-5cos(x) is the graphed equation. Cos(x) starts at (0,0) and one period is 2pi or 6.28 and by cos(x) multiplied by -5 starts the cosine wave at (0,-5) and thus corresponds to the graphed equation shown.

Any questions please feel free to ask. Thanks

Answer:

6/95.

Step-by-step explanation:

Prob(red marble on the first choice) = 4/(10+6+4)

= 4/20

= 1/5.
