Diferential Equations within Circuits Report

 

I do have the report I need more help with it. It’s about the 1st order differential equations with circuits and how it helps to find the volts drop and RL circuits. I need some one to edit and add to the report so it can reach 4-5 pages. I also have the resources for it.

2 paragraphs – discussion inequalities

 

Learning Goal: I’m working on a algebra discussion question and need an explanation to help me learn.

Post at least 2 paragraphs responding to the following prompts:

  • Provide diagram created based on your example of social inequality.
  • Write one inequality statements that can be inferred from your diagram, referring to your specific sub-groups (not the variables a/b/c).
  • Explain whether you feel these inequalities are true.
  • Express your conclusion as a mathematical inequality.
  • Explain who might be interested in these results, and why.

please finish these questions after watching the videos please

1.Which of the following was offered as an example of continuous sample space?

Group of answer choices

amazon ratings

zip codes

blood types

cholesterol levels

2.In probability, which represents the union of the event A and the event B?

Group of answer choices

P(A or B)

P(A | B)

P(B | A)

P(sample space)

P(A and B)

3. In probability, which represents the intersection of the event A and the event B?

Group of answer choices

P(sample space)

P(A | B)

P(B | A)

P(A or B)

P(A and B)

4.The rule of the complement, for some random event E, is that

Group of answer choices

P(E) = 1 – P(not E)

P(E) = P(not E)

P(E) = 1 / P(not E)

P(not E) does not equal P(E)

5. In the box of chocolates example in which you eat the first chocolate you pick, the successive chocolate picks are

Group of answer choices

randomized.

independent.

related.

dependent.

unrelated

6. In the pool example, we concluded that events DF and IC are dependent events because

Group of answer choices

IC causes pool filters to get dirty faster.

we found that P(IC | DF) was different from P(IC).

a pool can have both IC and DF.

a pool can have DF and not have IC.

8.The confusion of the inverse is:

Group of answer choices

confusing P(A) with P(not A)

confusing P(A | B) with P(B | A)

confusing P(A or B) with P(A and B)

confusing P(A) with P(B | A)

9.If “6ft+” stands for a human height of at least 6 feet, then P(6ft+ | man) is the probability

Group of answer choices

of being a man but not one who is 6ft+ tall.

of being a man if the person is 6ft+ tall.

of being 6ft+ tall but not a man.

of being neither a man nor 6ft+ tall.

of being a man and being 6ft+ tall.

of being 6ft+ tall if the person is a man.

10. If “6ft+” stands for a human height of at least 6 feet, then we can see from the distribution of adult heights shown in the videos that

Group of answer choices

P(man | 6ft+) = 1 – P(6ft+ | man)

P(man | 6ft+) < P(6ft+ | man)

P(man | 6ft+) > P(6ft+ | man)

P(man | 6ft+) = P(6ft+ | man)

joint probabilities

inverse probabilities

marginal probabilities

14. In probability, the rectangles making up a mosaic diagram are scaled to represent

Group of answer choices

marginal probabilities.

inverse probabilities.

conditional probabilities.

joint probabilities.
