Answer:
C
Step-by-step explanation:
Answer: A. 
Step-by-step explanation:
To find the slope we must find the change in y over the change in x. Δ
Or rise over run.
In the graph, we have two "good" points. (0, -6) and (4,0)
So for Δy 0 to -6 = -6
So -6 goes on top 
Now Δx goes from 4 to 0 so the change would be -4.
So now it becomes 
Since there are two negatives it becomes a positive.
Or simply put, 
I suppose this is in reference to the chance?
The chance of choosing either red or blue marbles is 50/50 considering that there if four of each type in the bag.
The person chose 2 times, and each time go a red marble. The chance of choosing either is still 50% and they are both equally likely to get chosen.

Step-by-step explanation:
The inscribed angle ABD is on half the central angle ACD, that is
∠ ABD = 0. × 50° = 25°
The measure of arc AD is equal to the central angle it subtends, thus
arc AD = 50°
