University administrators have developed a Markov model to simulate graduation rates at their school. Students might drop out, r
abruzzese [7]

Solution :

The percentage of the students who have a chance of repeating their current year = 3%

The drop out students for the first year and the sophomores = 6%

Drop out rate of first year and the seniors = 4%

Now for the state space :

S = { first year(1), sophomores(2), juniors(3), seniors(4), graduates(G), Dropouts(D) }

Therefore

the first year students are indicated as '1'

Sophomores are indicated as '2'

Juniors are indicated as '3'

Seniors are indicated as '4

Graduates are indicated as 'G'

Dropouts are indicated as 'D'

The transition diagram is attached below.

The probability of the students who have the chance of repeating their current year = 3/100 = 0.03

Probability of first year dropouts and sophomores = 6/100 = 0.06

Probability of dropout rate of juniors and seniors = 4/100 = 0.04

Therefore, the probability matrix can be made as :

              1        2        3        4       G        D

    \begin{matrix}1\\ 2\\ 3\\ 4\\ G\\ D\end{matrix}      \begin{bmatrix}0.03 & 0.91 & 0 & 0 & 0 & 0.06\\  0& 0.03 & 0.91 & 0 & 0 & 0.06\\  0& 0 & 0.03 & 0.93 & 0 & 0.04\\  0& 0 & 0 & 0.03 & 0.93 & 0.04\\  0& 0 & 0 & 0 & 1 & 0\\  0& 0 & 0 & 0 & 0 & 1\end{bmatrix}  

Here, G represents 'graduates' and D represents 'Dropouts.'

If electrons have a path to follow, they will flow to a area with charge
Natali [406]

Answer:

Hello there, the question is not complete, but not to worry you can check the explanation section to check how you can  solve a similar question or to be be able to solve the exact question directly.

Explanation:

The flow of electrons is what is known or refer to as Current. When energy is used on a nuclei, the electrons are forced to move from one position to the other. The direction of flow of electron is from the negative terminal which then moves to the positive terminal.

Therefore, it can be said that the positive charge determines the direction of electron flow. The starting point is the negative terminal, in which it will now move in the direction in which the positive terminal is.
