Question 19 (0.25 points)
You set the number type for cell A1 to Currency. If you type in the function =(RAND()*5) into cell A1, what would you expect to see as the result?
Question 19 options:
A random whole number between 1 and 5
A random dollar amount between $1 and $5.
Question 20 (0.25 points)
(True/False). You use the function =INT(RAND()*10) in cell B1. It results in a value of 7. If you simply copy/paste =INT(RAND()*10) from Cell B1 to Cell C1, the number appearing in Cell C1 would always also be the value 7.
Question 20 options:
True FalseExplanation / Answer
Question 1:
The statement “If the definition of IS is the medium for recording and storing data, and disseminating information, this would be an IS from a structural perspective” is false.
· A collection of people, resources, models etc which form as a structure and served for a function related to the organization is the structural perspective of an IS.
· The functional perspective says that information system is a medium which is used to record, store data, and disseminating information.
· The given definition of IS will be the functional perspective of information systems.
Question 2:
An information system is a system which can be used to collect the information received by a set of components such as data, hardware, software, people, etc.
Hence, the statement “an information system consists of the hardware, software, data, people, and procedures that work together to produce quality information” is correct.
Question 11:
The TPS is the transaction processing system which is used to support the business operations. The outputs of the TPS are as follows:
· Transaction documents
· Query response
· Reports
The report is a part of TPS because TPS generates following types of reports:
· Exception (error) reports
· Transaction logs
· Detailed reports
Exception reports show the queries containing exceptions.
Hence, the correct choice is exception reports.
Question 12:
The implementation phase is the phase of the software development life cycle in which the system is actually built and the code is written. This step will produce the output of the system. In this phase, it is to be identified whether the resources are completed and the implementation is completed.
Hence, the correct choice is implementation.
Question 13:
The information is modified according to the user’s requirements and the system is implemented in the system maintenance phase. This step is not present in the 9 step approach.
Hence, the correct choice is system maintenance.
Question 19:
Since the number type for the cell A1 is currency. Thus, the output numbers generated by the cell A1 will be preceded by currency sign ($). The function RAND() * N will generate the random numbers from 0 to N.
Hence, the correct choice is “A random dollar amount between $1 and $5”.
Question 20:
The statement “You use the function = INT(RAND() * 10) in cell B1. It the results in value of 7. If you simply copy/paste =INT(RAND() * 10) from cell B1 to cell C1, the number appearing in cell C1 would always be the value 7” is false.
· The value in the cell C1 may be 7 or not.
· The value generated by the function =INT(RAND() * 10) will generate the random integer number from 0 to 10 in the cell C1, if the function =INT(RAND() * 10) copied from cell B1 and pasted in the cell C1.
