Answer:
Step-by-step explanation:
The First Question !
This is simple,
So first we set this problem up
2 Red + 3 Blue + 7 Green = 12 Total Marbles
The formula for calculator probability is
# of favorable outcomes / # of possible outcomes
The number of favorable outcomes we have is 3 because we are trying to find the probability of pulling out a blue marble
The number of possible outcomes is 12 because we have 12 total marbles
3/12 simplifies to 1/4 which is .25
The probability of drawing a blue marble is 0.25 or 25%
Second Question!
The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25. The second useful rule is the Sum Rule.

A variable next to any number means to multiply, so we would do the inverse operation -- We would divide 0.48 by 0.6, which is 0.8. Therefore, W=0.48. To check your work, multiply 0.6 by 0.8, and what do you know? It's 0.48! :)
Answer:
317°
Step-by-step explanation:
The total measure of the angles around the center of the circle is 360°. The sum of angles in each half (above AB or below AB) is half that, or 180°. So, the sum of angles below the line is 180°. We can use that fact to find x, then the measures of all of the angles.
(7x +1)° +90° +(9x -7)° = 180°
16x = 96 . . . . . divide by °, subtract 84
x = 6 . . . . . . . . divide by 16
Then angle AOD is ...
(7·6 +1)° = 43°
Short arc AD is 43°, so long arc ACD is 360° -43° = 317°.
arc ACD = 317°
