The bag contains,
Red (R) marbles is 9, Green (G) marbles is 7 and Blue (B) marbles is 4,
Total marbles (possible outcome) is,
Let P(R) represent the probablity of picking a red marble,
P(G) represent the probability of picking a green marble and,
P(B) represent the probability of picking a blue marble.
Probability , P, is,
Probablity of drawing a Red marble (R) and then a blue marble (B) without being replaced,
That means once a marble is drawn, the total marbles (possible outcome) reduces as well,
Hence, the best option is G.
Answer:
AB = 5.2
AC = 5.2
m∠3 = 30 degrees
, m∠4 = 30 degrees
Step-by-step explanation:
Triangle ABO and ACO are both 30 60 90 triangles and are equal
Therefore If we have two sides then we can figure out the last side

Answer:
Step-by-step explanation:
The ratio of copies printed is ...
X : Y = 1 : 2
so the ratio of the number printed by machine X to the total is ...
X : (X+Y) = 1 : (1+2) = 1 : 3
1/3 of the 159 copies were printed by machine X, so it printed ...
(159)(1/3) = 53
Twice that many were printed by machine Y, so it printed ...
2·53 = 106
Machine X printed 53 copies; machine Y printed 106 copies.
