Some query questions, homework

students(sid,name,age,gpa)• courses(cid,deptid, description)• professors(ssn,name,address,phone,deptid)• enrollment(sid,cid,section,grade). cid makes reference to the courses table.• teaches(cid,section,ssn). cid, section makes reference to the enrollment table

Assume that small sections have less than 30 students, medium sections have at least 30

students but less than 80, and large sections have at least 80 students.

Your result table should have the following rows and columns:deptid small medium largecsmath… … … …Each table entry must have the number of sections of a given size offered by each department.9. List of professors that work for departments with more than 20 faculty members and that offermore large sections than small and medium sections combined.10. Assume grades are A, B, C, D, F where D and F are failing grades. For each course (section)find the percentage of students that failed the course.11. Find the name of the professor with the maximum percentage of students that failed his course.12. On average what percentage of students fail a course? (total number of students that failed acourse / total number of enrolled students).13. Find a list of courses (sections) where the percentage of students with D or F is greater thanaverage.

14. Write a query that produces the following table:deptid SPS % A % B % C % D % Fcsmath… … … … … … …Where SPS is the average number of students in each section and column %A has the per-centage of students that got an A, and so on, over all the courses offered by each department.

Suppose a system supports segmentation of memory. The address space has just 2 segments, and the top bit of the 10-bit virtual address indicates which segment it is in: segment 0 (code, heap), and segment 1 (stack). Segment 0 grows in positive direction, Segment 1 in negative direction. Given the following parameters:

Address space size:             1K

Physical memory size:         16K

Segment register information:

  Segment 0 base  (grows positive) : 0x000004ca (decimal 1226)

  Segment 0 limit                  : 382

  Segment 1 base  (grows negative) : 0x0000329e (decimal 12958)

  Segment 1 limit                  : 314

Virtual Address Trace

  VA  0: 0x0000030d (decimal:  781) –> PA or segmentation violation?

  VA  1: 0x0000030d (decimal:  781) –> PA or segmentation violation?

  VA  2: 0x0000014e (decimal:  334) –> PA or segmentation violation?

  VA  3: 0x0000023a (decimal:  570) –> PA or segmentation violation?

  VA  4: 0x0000016d (decimal:  365) –> PA or segmentation violation?

For each virtual address, either write down the physical address it translates to

OR write down that it is an out-of-bounds address (a segmentation violation).

For this discussion, you must read Chapter 8 and Chapter 9 of the text, Sociology: Beyond Common Sense, the article The ‘Pink vs Blue’ Gender Myth, and watch the three videos, Social Construction,[Transcript]  RACE: Are We So Different?, and A Girl Like Me [Transcript]. [Note that A Girl Like Me uses words or language that are considered profane, vulgar or offensive by some viewers. Ashford University does not condone such content that may be objectionable; however, the video is being used due to its impact and education value in understanding social construction.] After reviewing these resources on varied perspectives of social construction, consider the following questions:

  • What is social construction?
  • Which example from the resources provided did you find most compelling in building your knowledge of social construction? Describe it and explain why you found it most useful.

Your initial post should be at least 250 words in length. Support your claims with examples from required material(s) and/or other scholarly resources, and properly cite any references. 

Social constructions depend on the worldviews that are possessed by differentsocieties across the globe. It is due to the social constructions that societies view the roles ofthe two major…
