Alex bought a new truck for $42,935. According to the dealer, the truck will depreciate approximately $4,200 per year. Write and
Andrews [41]

Answer:

The truck is worth $5,135 when 9 years have passed

Step-by-step explanation:

Initial value of Alex's new truck: $42,935

Loss of value per year: $4,200

If n years passed, the truck would have lost

4,200n\ dollars

The current value of the truck will be

V(n)=42,935-4,200n

We want to know the value of n at which V is 5,135

5,135=42,935-4,200n

Solving for n

n=\frac{42,935-5,135}{4,200}

n=9 years

What condition on the probability distribution is necessary and sufficient in order that a limiting distribution exist, and what
Sholpan [36]

Answer:

The Markov chain is a description of the sequence of possible events in which the probability of an event depends only on the state attained in a previous separate event.

Step-by-step explanation:

The relation described by the Markov chain satisfies the following conditions:

1. All states communicate with themselves, that is P₁₁⁰ = 1 ≥ 0

2. There must be symmetry: if i←→j, then j ←→i

3. There must be transitivity. That is if i ←→k and k←→j, then i←→j

The conditions above imply that the communication is an example of an equivalence relation, meaning that it shares the properties with the more familiar relation, that is

i = i , if i = j ,then j = i etc
