Answer:
Constants.
Explanation:
In some languages, it is possible to define special variables which can be assigned a value only once – once their values have been set, they cannot be changed. We call these kinds of variables constants.
Answer:
Please check the attachment.
Explanation:
Firstly we need to draw the state diagram or the transition table. It clearly states through 4 bit even up counter that the next state of 0000 is 0010, and of 0010 is 0100 and so on. So we have the state diagram and the transition table, and thus answer for 1st and 2nd question.
Now through the Karnaugh map, we get the input circuit for D1, D2, D3, and D4. And these are mentioned in the attachment. Remember D outputs the same. which is the input. Thus, we have the answer for 3rd question. And then we draw the diagram, which can be found in the attachment. And this is the answer for the fourth question.
The correct answer is A: True
1. What does it mean to say that two variables are negatively correlated?
Correct answer: A) When one variable increases, the other decreases.
explanation:
Negative correlation is a relationship between two variables in which one variable increases as the other decreases, and vice versa.
