Answer:

Step-by-step explanation:
Part 1: Solve for the total amount of marbles
To solve for the probability of certain events, a population is needed to derive this information from. In order to find this population, add up the amounts of each marble.
8 + 14 + 12 = 34 marbles
Part 2: Determine the probabilities
Now, given the amounts of marbles, simply multiply the ratios of blue marbles to total marbles and the ratio of clear marbles to total marbles to get the combined probability.

The probability of these events occurring simultaneously is 15%.
Answer:
try C if not then A B or D
Step-by-step explanation:
"five times the sum of thirty-six and nine"
Let,
12x + 15y =34--------(1)
-6x + 5y =3-------(2)
(2) x 2 = -12x + 10y =6-------(3)
(3) + (1)
20y =40
y= 2
substitute y=2 into (1)
12x + 15(2) =34
12x =4
x= 1/3
2πr^2 + 2πrh.
r is the radius circle face.
h is the length/height of the cylinder.
πr^2 is the formula for circles, and there are 2 circles in a cylinder. So 2 x πr^2 would be determine the area of the 2 circles.
2πr is the formula for circumference. 2πr x h would the area of the curved face.
