[填空题]
An information technology :fj4 xyi 77 xjxnq.*ou(IT) c i*yabzzq14u2 ompany offers paid travelling vacation to its 160 employees every year. The employees can choose between travelling domestically or internationally. It bz 1*q2uaziy4is observed that 50 % of the employees who choose to travel domestically one year, choose internationally the next year. Conversely, 30 % of those who choose to travel internationally one year change to travel domestically the following year. For this year, 80 employees chose travelling domestically and 80 employees chose travelling internationally.
1. Write down the initial state $\boldsymbol{s}_{0}$ and the transition matrix $\boldsymbol{T}$ .$\boldsymbol{T}=\left[\begin{array}{ll}
a & b \\
c & d
\end{array}\right]$ a = b = c = d = $\boldsymbol{s}_{0}=\left[\begin{array}{l}
a \\
b
\end{array}\right]$ a = b =
2. Determine $\boldsymbol{T} \boldsymbol{s}_{0}$ and interpret the result. $Ts_0$$\boldsymbol{s}_{0}=\left[\begin{array}{l}
a \\
b
\end{array}\right]$ a = b =
3. Find the eigenvalues and corresponding eigenvectors of $X_1$=$\boldsymbol{T}$ .$\boldsymbol{s}_{0}=\left[\begin{array}{l}
a \\
b
\end{array}\right]$ a = b = $X_2$=$\boldsymbol{T}$ .$\boldsymbol{s}_{0}=\left[\begin{array}{l}
a \\
b
\end{array}\right]$ a = b =
4. 1. Write an expression for the number of employees who choose travelling internationally after n years, n $\in \mathrm{N}$ .
2. Hence find the long term steady state number of employees to choose to travel internationally.
