A system can be in one of the three states 1, 2, and 3: In state 1 it operates most efficiently. In state 2 it is still working but its efficiency is lower than state 1. State 3 is the down state, the system no longer operating and has to be maintained. State changes can only occur after a fixed time unit of length 1. Transitions into the same state are allowed. If X denotes the state at , time n, then {X0, Xt,...} is assumed to be a Markov chain with transition matrix , (1-7v ) 1 2 3 V0.8 0.1 0.1\ 2 0 0.6 0.4 3 0.8 0 0.2 (a) Find the stationary state probabilities. _ (b) Suppose the system makes per unit time profits of $1000 in state 1, $600 in state 2, and loses $100 at state 3. Find long term mean profit per unit time.

5/12, or 5: 12

step-by-step explanation:

i think the answer is b.

step-by-step explanation:

not 100% sure though.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
