Explanation:
First, Romeo draws a marble from the jar and does not replace it.
Next, he flips a coin.
The outcome from the second event is not affected by the event of picking a marble.

Answer:
Step-by-step explanation:
The three methods most commonly used to solve systems of equation are substitution, elimination and augmented matrices. Substitution and elimination are simple methods that can effectively solve most systems of two equations in a few straightforward steps.Understand what multi-variable equations are. Two or more linear equations that are grouped together are called a system. That means that a system of linear equations is when two or more linear equations are being solved at the same time.[1] For example:
8x - 3y = -3
5x - 2y = -1
These are two linear equations that you must solve at the same time, meaning you must use both equations to solve both equations.
The coefficient C-term is 1 in problem. The coefficient is the number before the variable of said equation. Example, the coefficient of X for thus problem 4x-4y is 4 the number BEFORE the variable, never variable itself it won’t ever be 4x
Answer:
12
Step-by-step explanation:
Alr so correct me if I'm wrong but I think you made a mistake. It says find 44 of those rectangles. You found just 1 in that case which the area is 3/11. You have to do 3/11 X 44 which is
3/11 x 44/1 = 132/11 = 12.
As I said, correct me if I'm wrong.
Hope this Helps!
