Answer:
3/10 or 30% chance red and green being pulled
Step-by-step explanation:
to get your fraction you do your amount wanted pulled (red and green) over the amount total (all of the colors)
24 + 12 = 36
40 + 24 + 12 + 24 + 20 = 120
36/120 now reduce 6
6/20 reduce by 2
3/10
Looks like the PMF is supposed to be

which is kinda weird, but it's not entirely clear what you meant...
Anyway, assuming the PMF above, for this to be a valid PMF, we need the probabilities of all events to sum to 1:

Next,





If

, then

, where we take the positive root because we know

can only take on positive values, namely 1, 2, and 5. Correspondingly, we know that

can take on the values

,

, and

. At these values of

, we would have the same probability as we did for the respective value of

. That is,

Part (5) is incomplete, so I'll stop here.
It woulds be x+15 because if you take 2x and subtracted from the 3x then you get x and then you add the 9 and 6 witch you get 15

Answer:
C).
Step-by-step explanation:
One of the points on the graph that the path of bike b crosses is (6,60).
When you divide this to find the unit rate you get 10/1 therefore the equation of bike b= y+10X
