A state vector X 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 no

Vesna [10]

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 $\mathbf x=(0.2,0.64,0,0.16)$ .

If i travel 100 miles in 4 hours what is that unit rate

lutik1710 [3]

100 miles in 4 hours. The unit rate would be 25 miles per hour.

100miles / 4hrs = 25 miles per hour

Therefore, for every hour you travel, you will gain 25 miles. Or for every 25 miles you travel, you've spent 1 hour traveling it.

y = 25x
where y is the total miles traveled, 25 is the constant unit rate, and x is the number of hours traveled.

for example: you traveled for 8 hours and you want to know how long you've traveled while maintaining the rate of 25mph. Just use the formula

y = 25x
y = 25(8)
y = 200 miles. you have traveled 200 miles in 8 hours.

Three persons had dinner in a restaurant. The total bill came to $51.60.

SVETLANKA909090 [29]

Answer:

Each person tipped $4.30.

Step-by-step explanation:

We know that the total bill was $51.60. The three people paid a 25% tip, which was split evenly among them.

Since the tip is 25%, it will be 25% of the total. Hence:

$0.25(51.6) = \$ 12.9$
