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%

Please help me define the variables and write out each equation. TY!

juin [17]

Answer:

The equations are:

10x + 9y = 122

x + y = 13

Step-by-step explanation:

Given Jose makes 10$ per hour washing cars and 9$ per hour walking dogs.

Also, it is given that he had worked for 13 hours total making 122$.

Let us assume the number of hours he spent on washing cars = 'x'.

Let us assume the number of hours he spent on walking dogs = 'y'.

Since, the total number of hours is 13, we can write:

x + y = 13 . . . eqn(1)

And since he has made 122$ in total, we will have:

10x + 9y = 122 . . .eqn(2)

'10x' represents the total money earned by washing cars and '9y' represents the total hours spent on walking dogs.

Hence, Eqn (1) and Eqn(2) is the answer.

Solving them will give: x = 5 and b = 8.
