The construction of a dual D(G) can be applied in any plane graph G: draw a vertex of D(G) in the middle of each region of G and draw an edge e* of D(G) perpendicular to each edge e of G; e* connects the vertices of D(G) representing the regions on either side of e.

a) A dual need not be a graph. It might have two edges between the same pair of vertices or a self-loop edge (from a vertex to itself). find two planar graphs with duals that are not graphs because they contain these two forbidden situations.

C) Show that the degree of a vertex in dual graph D(G) equals the number of boundary edges of the corresponding region in the planar graph G.

E) show for any plane depiction of a graph G that the vertices of G correspond to regions in D(G)

It's a well known fact that an observer that accelerates at a constant rate from ?c at past infinity to +c at future infinity sees a horizon in flat Minkowski spacetime. This is easy to see from a spacetime diagram once you realize that the union of past light cones on such a trajectory has a boundary that divides the spacetime into two regions - one inaccessible by the accelerating observer.

This leads to the classic result of Unruh radiation when one looks at the quantum field theory for such an observer. The horizon plays a crucial role here.

How does one go about determining whether a horizon is seen by a general class of worldines? In particular, is there any reason to believe that a horizon would exist for an observer that is stationary for all time except for a finite period of acceleration and deceleration?

Is there any other class of worldlines other than an indefinitely accelerating observer for which a horizon is known to exist in flat spacetime?

Full-time college students report spending a mean of 26 hours per week on academics activities, both inside and outside the class room. Assume the standard deviation of time spent on academic activities is 5 hours. If you select a random sample of 16 Full-time college students, what is the probability that the mean tie spent on academics is at least 24 hours per week? b. If you select a random sample of 16 full-time college students, there is an 87% chance that the sample mean is less than how many hours per week?

After receiving their mid-term grades, four students formed a study group. On writing assignments they have turned in since forming the study group, the students’ responses are “too” similar, almost to the point of being exact copies. Recognizing these similarities might have resulted from the common wording the students use while studying, their teacher cannot decide whether to forget the situation or accuse the students of academic dishonesty. Expressed in words, not symbols, what are the null and alternative hypotheses in this situation? Explain why you chose these as the hypotheses and What you would to test you hypotheses?

a. Suppose that the election of a popular candidate suddenly increases people’s confidence in the future. Use the model of aggregate demand and aggregate supply and a graph to analyse the effects on the economy.

b. Suppose now a wave of negative animal spirits overruns the economy, and people become pessimistic about the future. What happens to aggregate demand? If the Central Bank (or Fed) wants to stabilise aggregate demand, how shout it alter the money supply? If it does this, what happens to the interest rate? why might the Central Bank (or Fed) choose not to respond in this way?

Is it possible to include some academic references aswell please? Thanks

Your University wish to determine how alcohol consumption patterns among students impact their GPAs. You and your classmates’ task (as a group) is to discuss and formulate a RESEARCH PROPOSAL, proposing how the research would be conducted, from start to completion, step-by-step, in order to ultimately produce a useful and dependable report that would guide the University in introducing positive measures that improve students’ academic qualities. Among many things, you and your classmates would definitely want to propose the inclusion of any descriptive statistics and tests that are useful in uncovering the relationship between alcohol consumption patterns and GPAs achieved.

6) Discuss any concept from Deidre Mcloskey other than the importance of prices in conveying information to producers and consumers. You need to CLEARLY identify the source (i.e. name of the book and page, or link of the video and time, or name and link of the website). It is preferred that you use academic resources or books from the library.

What does the term "Oppression Olympics" mean? and give example.

What does the term "intersectionality" off us? What I mean is there are lots and lots of academic terms, right? So what's new about intersectionality? What does it do that other terms have not done? Does it "advance" other theories?

Can you name another Intersectional system? Or just start here: Can you name another system where you are both the oppressor and the oppressed within the same system? It's not an easy question. Give it some thought and then throw something out there.
