Answer:
7/80
Step-by-step explanation:
(3 green, 4 yellow, 5 blue, 8 pink) = 20 marbles
P ( green or yellow ) = number of green or yellow / total
= (3+4)/20 = 7/20
Replace
so we have (3 green, 4 yellow, 5 blue, 8 pink) = 20 marbles
P (blue) = number of blue/ total
= 5/20 = 1/4
P ( green or yellow, replace, blue) = 7/20 * 1/4 = 7/80
Answer:
The second answer - 40, 10, 20, 50

Answer:
D but read below.
Step-by-step explanation:
I take it that the symbol ~ stands for similar. If that is so, then the answer you want is AA, because if 2 angles in a triangle are equal, then all 3 are. So if any 2 equal angles in one triangle are equal to 2 angles in another, then the two triangles are similar.
Answer:
y^2 +8y + 16
Step-by-step explanation:
6y^2 +2y +5 - (5y^2 -6y -11)
I distribute the minus sign
6y^2 +2y +5 - 5y^2 +6y +11
Then I put them vertical.
6y^2 +2y +5
-5y^2 +6y +11
------------------------
y^2 +8y + 16
This is in standard from since the exponential decreases.
