Answer:
6 blue marbles
Step-by-step explanation:
Given;
Total number of marbles N = 15
probability of randomly selecting a green marble
P(G) = 1/5
The probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble P(G∩B) = 2/25
P(G∩B) = P(G) × P(B)
P(B) = P(G∩B) ÷ P(G)
The probability of selecting a blue marble
P(B) = 2/25 ÷ 1/5 = 2/5
The number of blue marbles N(B) = P(B) × N
N(B) = 2/5 × 15 = 6
There are 6 blue marbles
Answer:
4 ft
Step-by-step explanation:
The volume of a cube of side length s is V = s^3. Solving for s^3, we get:
s^3 = V, and so s = ∛V
In this case, with V = 64 ft³, the desired side length is
s = ∛(64 ft³) = 4 ft
Write these steps down
Positive times positive=positive
Negative times positive=negative
negative times negative= positive
when any two numbers that are negative it will always equal a positive.
Its a rule for math.
Answer:
y = -2/3 + 18
Step-by-step explanation:
2x + 3y = 18 ----- here is the equation...
-2x - 2x ----- bring the 2x to the other side
3y = -2x + 18 ----- now you have to divide everything by 3 to get y by itself
y = -2/3 + 18 ----- Done!
