1) Describe the performance impact of using the LIKE operation with a wild card character at the beginning of the value.

2) Under what circumstances is a non-matching index scan performed?

3) A query is written to access a single table. Furthermore, that query will return only a single row because an equality predicate is coded on the primary key for the table. A unique index exists to support the primary key. What type of access is likely to be the most efficient for that query?

4) How can stored procedures be used to optimize performance in a client/server application?

5) Under what circumstances will a table scan outperform indexed access?

Programming Language: C++

Create a base class called Shape which has 2 attributes: X and Y (positions on a Cartesian coordinate system). Since a shape is amorphous, set the class up so that an object of type Shape can not be instantiated.

Create three derived classes of your choice whose base class is Shape. These derived classes should have accessors/mutators for their class specific attributes, as well as methods to compute the area and the perimeter of the shape.

In main(), create a stack of pointers to Shape and push one object of each derived class onto the stack. Then, pop each shape pointer off of the stack and output that shape's area and perimeter, demonstrating polymorphism.

1. Mike and Suzanne have a daughter (Michelle) and a son (Jack). Michelle is 25 years old, working in a law firm. Jack is only 18 years old. Next year, Jack will start at the University of Adelaide as a student. As a family tradition, they have been doing lottery syndicate for years. They collect money and pay together, using their birthday numbers to play in the lottery. One day, Jack bought one lottery ticket, and later on, surprisingly found out he won 1 million Dollar. Now Jack wants to take all money for himself and leave his parents’ house to start a new life. Do you think Jack can do so? Would Mike, Suzanne and Michelle have any claim in this lotter?

Clarify the differences between the types of location sensors built-in to the mobile device. And how the Location information is accessed within an app?

An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 4.0 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 15 engines and the mean pressure was 4.3 pounds/square inch with a standard deviation of 0.7. A level of significance of 0.05 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.

Items are sometimes fastened to plastic parts by screw driven into smooth holes molded in the parts. Over time, however, the screws loosen. To what common laboratory test of viscoelasticity does this correspond? (Provide explanation)

If 5.01 g of Ag2O is sealed in a 75.0-mL tube filled with 760 torr of N2 gas at 24 ∘C, and the tube is heated to 380 ∘C, the Ag2O decomposes to form oxygen and silver.

What is the total pressure inside the tube assuming the volume of the tube remains constant?

Express your answer to three significant figures and include the appropriate units.

Q/ Write and explain 2 techniques that used for gene expression analysis on protein level??

A. Iva Ertarm is admitted complaining of a numb right arm. When tested, she is unable to feel when her hand and arm are touched lightly, but can still feel a hard pressure. It is determined she must have a lesion or damage within her spinal cord. Which specific pathway is affected (4 pts)? How do you know it is that specific pathway (Apts)? Which side of the spinal cord is the lesion and which funiculus must! the lesion be located (4 pts)? How do you know the specific funiculus and the side (where does it decussate) (4pts)? What is the signal direction within this pathway and what is the final destination of this information (2 pts)? 2 pts for essay formatting, grammar, spelling. Be specific in your answers.

Use SPSS for this Application Exercise:
A psychologist hypothesizes that depression increases with aging. It is known that the general population scores a 40 on a standardized depression test where a higher score indicates more depression. The psychologist obtains a sample of individuals that are all over 68 years old. What can the psychologist conclude with α = 0.01? The data are below.

a) What is the appropriate test statistic?
---Select--- na z-test One-Sample t-test Independent-Samples t-test Related-Samples t-test

b)
Population:
---Select--- standardized depression test elderly aging general population depression
Sample:
---Select--- standardized depression test elderly aging general population depression

c) Compute the appropriate test statistic(s) to make a decision about H₀.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
p-value =  ; Decision:  ---Select--- Reject H0 Fail to reject H0

d) Using the SPSS results, compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and/or select "na" below.
d =  ;   ---Select--- na trivial effect small effect medium effect large effect
r² =  ;   ---Select--- na trivial effect small effect medium effect large effect

e) Make an interpretation based on the results.

The elderly are significantly more depressed than the population.

The elderly are significantly less depressed than the population.    

The elderly did not significantly differ on depression than the population.

Laws for Accountants

How will a state and /or federally mandated requirement for late payments not to be considered late impact the bankruptcy laws? What about the many businesses that have been required to close-should there be some consideration given to that fact when many of these business file for bankruptcy? What about those who lose their jobs because their businesses are required to close? What does this do to their lenders and their banks?

5 Three Pirates Sharing 100 Gold Coins

Three pirates of different ages have a treasure of 100 gold coins. They decide to split the coins using this scheme:

• The oldest pirate proposes how to share the coins, and ALL pirates (including the oldest) vote for or against it.

  • – If more than 50% (exclusive) of the pirates vote for it, then the coins will be shared that way and the game ends. Otherwise, the pirate proposing the scheme will be thrown overboard, and the process is repeated with the pirates that remain. Note that if exactly 50% of the pirates vote for it, then the pirate proposing the scheme will be thrown overboard.

  • – As pirates tend to be a bloodthirsty bunch. If a pirate would get the same number of coins if he voted for or against a proposal, he will vote against so that the pirate who proposed the plan will be thrown overboard.

• Assuming that all 3 pirates are intelligent, rational, greedy, and do not wish to die, (and are rather good at math for pirates).

1. What will happen?

2. Assume now Captain Hook spots the scene and wants to share the gold as well. That is, now we have four pirates sharing the coins. Captain Hook will be the first to propose a scheme to share the coins. Assume the same rule applies. What will happen?
