What is the equation of the following line? Be sure to scroll down first to see

olchik [2.2K]

Answer:

$y=6x$

Step-by-step explanation:

we have the ordered pairs

(0,0) and (-1/2,-3)

In this problem we have a proportional relationship, because the line passes through the origin

A proportional variation can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

Find the value of the constant of proportionality k

For x=-1/2, y=-3

$k=\frac{y}{x}$ ----> $k=\frac{-3}{(-1/2)}=6$

therefore

The linear equation is equal to

$y=kx$

substitute the value of k

$y=6x$

Could the given matrix be the transition matrix of a regular Markov chain?

labwork [276]

Answer:

Following are the answer to this question:

Step-by-step explanation:

Matrix:

$A=\left[\begin{array}{cc}0.3&0.7\\1&0\end{array}\right]$

$A^2=\left[\begin{array}{cc}0.79&0.21\\0.3&0.7\end{array}\right]$

In the above-given matrix, all entries of the matrix A² will be positive and the matrix A will be the transition of the matrix A, that regulates the Markov chain.
