1. Working with Stairs: Proficiency with laying out stairs and proportioning their treads and risers, even at times under seeming impossible circumstances, is an indispensable skill for the designer of buildings. For this exercise, review pages 288 through 289 (proportioning stairs) of the text for the information you will need.

5. Do you intend on choosing products in which companies practice sustainability?
6. Are we as consumers part of the problem, if we buy goods mindlessly without considering the potential environmental problems behind the packaging, the product, the environmental waste?

SIS is a management information system for education departments used to manage student data. SIS provide capabilities for registering students in courses; documenting results of student tests and other assessment scores; building student schedules; tracking student attendance; and managing many other student-related data needs in a school or universities.

In this regard, you are asked to do some research about SIS, select one of the aspects that managed by SIS and then design two database tables about this aspect [14 marks] and another database table that represents a relation between the previous two tables [6 marks]. For each table you need to:

1. Define the objective(s) of the table.
2. Design at least five fields for the table; data type and size.

3.Determine the primary key of the table.

On a planet far far away from Earth, IQ of the ruling species is normally distributed with a mean of 119 and a standard deviation of 15. Suppose one individual is randomly chosen. Let X = IQ of an individual. a. What is the distribution of X? X ~ N( 119 , 15 ) b. Find the probability that a randomly selected person's IQ is over 113. Round your answer to 4 decimal places. c. A school offers special services for all children in the bottom 2% for IQ scores. What is the highest IQ score a child can have and still receive special services? Round your answer to 2 decimal places. d. Find the Inter Quartile Range (IQR) for IQ scores. Round your answers to 2 decimal places. Q1: Q3: IQR:

The fundamentals of firewall and its basics can be described by the following, except one? Justify your choice?

1. Like a sentry at the border or a gateway, a firewall watches for traffic that fails to comply with the rules or filters defined by a firewall administrator.
2. There is still a disagreement among network administrators as to whether firewall is a key component of infrastructure security or a hinderance to essential network security tasks.  
3. Default-deny or default-allow are the two main philosophies or security stances that govern the use of rules, where a default-deny stance assumes that all traffics are potentially malicious, at least unwanted, or unauthorized, and a default-allow stance assumes that most traffics are benign.
4. It is inaccurate or an overstatement to say that every network needs a firewall, at home, work, school, or otherwise because firewall is not fundamental to network communications.

The Graduate Record Examination (GRE) is a test required for admission to many U.S. graduate schools. Students' scores on the quantitative portion of the GRE follow a normal distribution with mean 150 and standard deviation of 8.8. In addition to other qualifications, a score of at least 160 is required for admission to a particular graduate school.

a. What proportion of combined scores can be expected to be over 160?

b. What proportion of combined GRE scores can be expected to be between 155 and 160?

c. What is the probability that a randomly selected student will score less than 150 points?

d. Historically, Department of History at NYU has admitted students whose quantitative GRE score is at least at the 61st percentile. What is the lowest GRE score of the students they admit?

e. Determine the range of scores that make up the middle 95% of the scores.

For this exercise, select two people in leadership positions to interview. They can be leaders in the formal or informal positions at work, school, or society.

Conduct a 30-minute interview with each leader – ask the leaders to describe the visions they have for their organizations. In addition, ask, “How do you articulate and implement your visions”.

Leader #1 – is the leader vision content, vision articulation, or vision implementation?

Leader #2 – is the leader vision content, vision articulation, or vision implementation?

• What differences and similarities did you observe between the two leaders?
• Did the leaders advocate specific values? If so, what?
• Did the leaders use any unique symbols to promote their visions? If so, what?
• In what ways did the leaders behaviors model their visions to others?

2-) Methane gas enters an uninsulated horizontal pipe with a thin wall of 25 cm in diameter at a temperature of (300+ ??) C with 4.5 tons of mass flow per hour and exits at (280+ ??) C. The pipe is smooth and its length is 10 m and the ambient and environmental temperature is 25 C. Since the smear coefficient of the pipe surface is given as 0.8; (?? = school no. last two digits, for example 0611002072; ?? = 72, ie 300 + 72 = 372 C and 280 + 72 = 352 C) a-) Indoor and outdoor convection coefficients (W / m K), b -) Calculate heat loss from the pipe to the environment (W), c-) Surface temperature of the pipe (C), d-) Calculate the required fan power (W) and interpret the results.

A friend has approached you for advice because they know you are in an investments class. The friend’s grandfather has made a gift to the friend of $25,000 with the requirement that the money be used to invest in a minimum of 5 individual stocks. (The grandfather is an old-school stock investor and feels strongly that investing in stocks will help your friend understand the markets and the economy and will improve your friend’s decision-making skills.)

What are the three things you would want your friend to understand before they begin investing? In addition to those three things, how would you advise your friend to go about evaluating what stocks to choose? (You are not recommending a stock, you are advising them how they can choose a stock.) Finally, would you suggest they go about executing their transactions?

Tekashi is currently dating his girlfriend Sara. Sara does not have a job, nor does she go to school. Sara also has no income. Tekashi pays $10,000 towards Sara’s support and she lives with him during the entire year. Sara does not contribute to his own support.

1. Can Tekashi claim Sara as a “qualifying child” or “qualifying relative” dependent?

2. Tekashi has no children or possible dependents other than Sara. What is Tekashi’s filing status?

3.What if Sara’s mistress, Jenny, pays $10,002 towards Sara’s financial support? Does Sara still qualify as his dependent?

4. What if Sara only lives with Tekashi for 160 days of the year?
