The probability of selecting a yellow marble is #of yellow marbles/total # of marbles= 6/30 or .2 or 20%
If there are 300 marbles in the bag, a good estimate for the total number of red marbles in the bag is 90.
9/30=.3 = the percentage of red marbles
.3(300) = 90
X=6 because 2*6=12 and 12+4=16

Answer: Choice B) 128
Explanation:
We'll add up the given arc measures and then cut the result in half to get the angle formed by the intersecting chords (that subtend the arcs in question).
chord angle = (arc1+arc2)/2
x = (54+202)/2
x = 256/2
x = 128
