Answer:

x = -25/3

Step-by-step explanation:

$\frac{10}{3} = \frac{x}{ (\frac{ - 5}{2} )} \\ = > \frac{10}{3} \times \frac{ - 5}{2} = x \\ = > \frac{ - 50}{6} = x \\ = > \frac{ - 25}{3} = x$

Answer:

-8 1/3 or -8.333

Step-by-step explanation:

10/3 = x/( - 5/2)

Simplify - 5/2

10/3 = x/-2.5

Multiply -2.5 by 10

-25

Divide it by 3

-8.333

How to solve 4k-1.5k=50

padilas [110]

Combine like terms-- you can combine the k's:
$4k-1.5k=2.5k$

Now you have:
$2.5k=50$

Simply divide both sides by 2.5 to find the value of k:
$\frac{2.5k}{2.5}=\frac{50}{2.5}\\\\k=20$

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

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.

What is the area of the rectangle? Show ALL your work! Do not round at any point!

faust18 [17]

First lets work out the length of the top side which joins the points (-1,7) and (-5,5):-

this = sqrt ( (7-5)^2 + (-1 - (-5)^2 )

= sqrt (4 + 16)

= sqrt 20

Now find length of the longer side which is distance between the points (-1,7) and (4, -3)

this is sqrt ( (-1 - 4)^2 + (7 - -3)^2)

= sqrt 125

Area of the rectangle = sqrt 20 * sqrt 125

= sqrt 2500
