**Title: Understanding Steady-State Vectors in Transition Matrices**

**Find the steady-state vector associated with the given transition matrix. (Give exact answers. Do not round.)**

\[
\begin{bmatrix}
0.2 & 0.8 \\
0.1 & 0.9 \\
\end{bmatrix}
\]

This matrix represents a transition matrix often used in Markov processes. Each element in the matrix represents the probability of transitioning from one state to another. For example, in this matrix:

- 0.2 is the probability of staying in the first state.
- 0.8 is the probability of transitioning from the first state to the second state.
- 0.1 is the probability of transitioning from the second state to the first state.
- 0.9 is the probability of staying in the second state.

The goal is to find the steady-state vector, a vector that remains unchanged after applications of the transition matrix. This vector shows the long-term behavior of the system.

Below is a layout representing an unanswered system of equations, depicted by blank brackets, to compute the steady-state vector:

\[
\begin{bmatrix}
\text{\_\_\_} \\
\text{\_\_\_} \\
\end{bmatrix}
\]

Arrows indicate the direction of the equations, relating to inputs and transformations within the system.

**Key Concepts:**

1. **Transition Matrix**: A square matrix used to describe the transitions of a Markov chain. Each of its rows is a probability vector, meaning all elements are non-negative and each row sums to one.
   
2. **Steady-State Vector**: A probability vector, denoted usually by \(\pi\), that becomes stable, satisfying the condition \(\pi = \pi P\), where \(P\) is the transition matrix.

Understanding these concepts allows students to explore how systems evolve over time and reach equilibrium, which is integral in fields such as economics, genetics, and computer science.
