PLEASE ANSWER ALL AND WORK OUT!!

1. In a large metropolitan area, 25% of the commuters currently use the public transportation system, whereas the remaining 75% commute via automobile. The city has recently revitalized and expanded its public transportation system. It is expected that 6 months from now 30% of those who are now commuting to work via automobile will switch to public transportation, and 70% will continue to commute via automobile. At the same time, it is expected that 20% of those now using public transportation will commute via automobile and 80% will continue to use public transportation.

(a) Construct the transition matrix for the Markov chain that describes the change in the mode of transportation used by these commuters.

   P              A
T =
P
A



(b) Find the initial distribution vector for this Markov chain.

X0

=


(c) What percentage of the commuters are expected to use public transportation 6 months from now? (Round your answer to the nearest percent.)
%_______

2.

Solve the system of linear equations using the Gauss-Jordan elimination method.

2x + 2y + z = 8
x + z = 3
4y 3z = 16

(x, y, z) = __________

3.Solve the linear programming problem by the method of corners.

Maximize P = 4x + 7y    
subject to   x + y 10
3x + y 12
−2x + 3y 9
x ≥ 0, y ≥ 0  

The maximum is P =__________ at (x, y) = __________.

Problem in answer then comment below.. i will help you

By rules and regulations we are allow to do only one question at a time..so i do only question 3rf.

.

please thumbs up for this solution..thanks..

Maximize 4x, +7X2 subject to X1 + X2 = 10 3x, + X2 12 - 2X1 + 3x2 > 9 #3 FACTORY RESTRICTIONS EQUATIONS Maximize 4x, +7X2 sub#6 SIMPLEX TABLE 3 X1 X2 X3 X4 X5 y1 y2 b t X3 5/3 0 1 0 1/3 0 -1/3 7 21/5 y1 11/3 0 0 -1 1/3 1 -1/3 9 27/11 -2/3 1 0 0 -1/3

so , max P = 67 at (x,y) = (1,9)
