The city of Oakland is experiencing a movement of its population to the suburbs. At present 85% of the total population lives in
Oxana [17]

Answer:

A. \left[\begin{array}{cc}0.93&0.07&\\0.01&0.99&\end{array}\right]

B.   (0.85    0.15)

C. 79.2% population in the city while 20.8% population in the suburb

Step-by-step explanation:

(a) The transition matrix for the information is

                C        S

            \left[\begin{array}{cc}0.93&0.07&\\0.01&0.99&\end{array}\right]

(b) the probability vector for the information is

         (\frac{85}{100}  \ \   \frac{15}{100} )

and this gives us

         (0.85    0.15)

(c) we simply multiply the above  two matrices to find the percent of the population can be expected to be in each category after one year after

\left[\begin{array}{cc}0.85&0.15\end{array}\right] \left[\begin{array}{cc}0.93&0.07&\\0.01&0.99&\end{array}\right] = \left[\begin{array}{cc}0.792&0.208&\end{array}\right]

in the city there are 79.2% while in the suburb, there are 20.8%

Solve the equation<br><br> - 9x – 2y=-12<br> 2x+5y=-11<br><br> X=<br> Y=
inysia [295]

Answer:x=2, y=3

Step-by-step explanation:

solving this equation simultaneously

-9x - 2y=-12.............(1)

2x + 5y=-11.. ...........(2)

Using elimination method

Multiply equation 2 by 2 and equation 1 by 5

-45x -10y= -60...........(3)

4x + 10y=-22...............(4)

Subtracting equation 2 from 1

-41x + 0=-82

41x=82

x=82/41

X=2

To find y put x in equation 1

-9x - 2y= -12

-9(2)-2y=-12

-18-2y=-12

-2y=-12+18

-2y=6

Y= 6/2

Y=3

X=2, Y=3
