Answer (assuming the numbers are the side lengths...)

4. Right Scalene 5. Obtuse Isosceles 6. Acute Isosceles 7. Equilateral 8. Right Scalene 9. Acute Scalene

Step-by-step explanation:

It is a lot of explaining, so if you want to cheat then go to triangle-calculator.com and then type in a = (side 1) b = (side 2) c = (side 3) and it will do the work for you :)

A state vector X for a four-state Markov chain is such that the system is four times as likely to be in state 2 as in 4, is not

GREYUIT [131]

All the components in the state vector need to sum to 1. You're given that component corresponding to state 1 is 0.2, and that the component for state 3 is 0.

That leaves states 2 and 4, for which you're told that the component for state 2 is four times as large. If $x_i$ is the component for state $i$ , then you have

$x_1+x_2+x_3+x_4=1\iff 0.2+4x_4+0+x_4=1\implies5x_4=0.8\implies x_4=0.16$

which means $x_2=4x_4=0.64$ . So the state vector is $\mathbf x=(0.2,0.64,0,0.16)$ .
