Write the transition matrix for this problem. b. Find the proportion of agricultural land, urban land and land used for other purposes in this state one year later (1991). Label your answers. c. Find the proportion of agricultural land, urban land and land used for other purposes in this state in the year 2000. Label your answers.

Explanation / Answer

let P be transition matrix;

bi = [x;y;z] ; where x is percentage of Agriculture ,y  is percentage of urban land , z  is percentage of other uses.

given condition

P = [0.96 0 0.04 ; 0.03 0.99 0.02 ; 0.01 0.01 0.94];

P =

0.9600 0 0.0400
0.0300 0.9900 0.0200
0.0100 0.0100 0.9400

b0 = [0.48;0.18;0.34];

b0 =

0.4800
0.1800
0.3400 {b0 in year 1990

b) so in year 1991

b1 = P*b0

b1 =

0.4744
0.1994
0.3262

c) in year 2010

b10 = (P^10)*b0;

b10

b10 =

0.4145
0.3472
0.2383
