(Use Python) Data have been accumulated on the heights of children relative to their parents. Suppose that the probabilities that a tall parent will have a tall, medium-height, or short child are 0.6,0.2, and 0.2, respectively; the probabilities that a medium-height parent will have a tall, medium-height, or short child are 0.1, 0.7, and 0.2, respectively; and the probabilities that a short parent will have a tall, medium-height, or short child are 0.2,0.4, and 0.4, respectively. (a) Write down the transition matrix for this Markov chain. (b) What is the probability that a tall person will have a short grandchild? (c) If 20% of the current population is tall, 50% is of medium height, and 30% is short, what will the distribution be in three generations? (d) What proportion of the population will be tall, of medium height, and short in the long run?
(a) The transition matrix is: (b) The probability that a tall person will have a short grandchild is P_{13}^2 + P_{23}^2 + P_{33}^2. Using the transition matrix from part (a), we haveP_{13}^2 + P_{23}^2 + P_{33}^2 = (0.2)(0.2) + (0.2)(0.4) + (0.4)(0.2) = 0.12(c) If 20% of the current population is tall, 50% is of medium height, and 30% is short, we can represent the initial distribution as a row vector: X_0 = [0.2 0.5 0.3].
To find the distribution in three generations, we can multiply this vector by the third power of the transition matrix from part (a): X_3 = X_0P^3 = [0.2 0.5 0.3] * [0.5 0.1 0.4; 0.2 0.7 0.1; 0.2 0.4 0.4]^3 = [0.3506 0.4023 0.2471]In three generations, the distribution will be approximately 35.06% tall, 40.23% medium-height, and 24.71% short.(d) To find the long-run proportions, we need to solve for the stationary distribution, which is a row vector π such that πP = π and ∑π_i = 1. We can find this by solving the system of linear equations: π_1 = 0.6π_1 + 0.1π_2 + 0.2π_3π_2 = 0.2π_1 + 0.7π_2 + 0.4π_3π_3 = 0.2π_1 + 0.2π_2 + 0.4π_3π_1 + π_2 + π_3 = 1Substituting the third equation into the first two, we get: π_1 = 1.5π_3π_2 = 0.8π_3π_1 + π_2 + π_3 = 1Solving for π_3 in the second equation and substituting into the first equation, we get: π_1 = 0.6π_1 + 0.1π_2 + 0.2(0.625π_2)π_2 = 1.25π_1π_1 + π_2 = 1Substituting π_2 = 1 - π_1 into the first equation, we get: π_1 = 0.6π_1 + 0.1(1 - π_1) + 0.125π_1 0.325π_1 = 0.9π_1 + 0.1 0.575π_1 = 0.1π_1 = 0.174π_2 = 1 - π_1 = 0.826π_3 = 0.625π_2 = 0.516The proportion of the population that will be tall, medium-height, and short in the long run is approximately 17.4%, 51.6%, and 31.0%, respectively.

Object-oriented modeling is based on the object, which combines ________ .
A. data and processes
B. processes and trade-offs
C. data and priorities
D. classes and facts
E. programming and classes
Answer:
A. data and processes
Explanation:
In object-oriented modeling, objects are designed to encapsulate both data and the operations that can be performed on that data. This approach promotes modular and reusable code by organizing related data and behaviors into self-contained objects. By combining data and processes, object-oriented modeling enables developers to create models that closely mirror real-world entities or abstract concepts, resulting in more flexible and maintainable software systems.
