Let P = 0.50.30.50.7 be the transition matrix for a Markov chain with two states. Let x0 = 0.50.5 be the initial state vector fo
pav-90 [236]

Answer:

Probability distribution vector = \left(\begin{array}{c}0.375\\ 0.625 \end{array} \right)

Step-By-Step Explanation

If P=\left(\begin{array}{cc}0.5&0.3\\ 0.5&0.7 \end{array} \right)  is the transition matrix for a Markov chain with two states.  

x_{0}=\left(\begin{array}{c}0.5\\ 0.5 \end{array} \right)  be the initial state vector for the population.

X_{1}=P x_{0}=\left(\begin{array}{cc}0.5&0.3\\ 0.5&0.7 \end{array} \right) \left(\begin{array}{c}0.5\\ 0.5 \end{array} \right) =\left(\begin{array}{c}0.4\\ 0.6 \end{array} \right)  

X_{2}=P^{2} x_{0}=\left(\begin{array}{c}0.38\\ 0.62 \end{array} \right)  

X_{3}=P^{3} x_{0}=\left(\begin{array}{c}0.38\\ 0.62 \end{array} \right)  

X_{30}=P^{30} x_{0}=\left(\begin{array}{c}0.37499\\ 0.625 \end{array} \right)  

In the long run, the probability distribution vector Xm approaches the probability distribution vector \left(\begin{array}{c}0.375\\ 0.625 \end{array} \right) .

This is called the steady-state (or limiting,) distribution vector.

Nutka1998 [239]

Answer:

Jillian bikes 3 miles each evening.

3

Step-by-step explanation:

3 (miles) × 5 (days) = 15 (Run)

3 (miles) × 5 (days) = 15 (Bike)

30 miles total

Hope this helps!!

Check:

She works out twice a day and goes three miles each time for five days.

Six miles per day

6 · 5 = 30

Ix times a larger number is equal to the sum of a smaller number and 18. The difference of twice the larger number and the small
erma4kov [3.2K]

Answer:

6 times a larger number (so 6y) is equal (=) to the sum of a smaller number and 18 (x+18)

6y = x+18

Twice of larger number (2y) and the difference of smaller number (x) is equal to 6

2y - x = 6

solve for y. Divide both terms for 6.

6y/6 = 1/6x+3

y = 1/6x+3

second equation solve for y

move x to the right of equal

2y = x + 6

y = 1/2x + 3

A dilation has center (0, 0). Find the image of each point for the given scale factor.
balu736 [363]

Here we have a point and dilation factor and the dilation factor or the scale factor is 12 . SO we need to multiply each coordinate by 12, that is 0 times 12=0 and 4 times 12=48 .

So the image of point after dilation is (0,48) .

For what value of d is (2x - 3)(x + d) equivalent to 2x + 5x - 12? d =
dimulka [17.4K]

For this case we have the following expression:

(2x-3) (x + d) =

Applying distributive property we have:

2x ^ 2 + 2dx-3x-3d

This last expression must be equivalent to:

2x ^ 2 + 5x-12

So, matching we have:

2x ^ 2 + 2dx-3x-3d = 2x ^ 2 + 5x-12

Matching similar terms we have:

2dx-3x = 5x\\(2d-3) x = 5x\\2d-3 = 5\\2d = 5 + 3\\2d = 8\\d = \frac {8} {2} = 4

Thus, the value of d is 4. We verify:

(2x-3) (x + 4) = 2x ^ 2 + 8x-3x-12 = 2x ^ 2 + 5x-12

Answer:

d = 4
