A report is scheduled to run and be distributed at the end of business each day. On Mondays, one of the recipients opens the previous week's reports and combines them to calculate the weekly totals and projections for the coming week. This is a tedious process, and the recipient asks an analyst for help. Which of the following should the analyst recommend?
Correct Answer:
B
Creating a new report that automatically calculates weekly totals would streamline the process for the recipient. By setting this report to run at the end of business on Friday, it would provide the recipient with the necessary information for the entire week in one consolidated document. This eliminates the need for manual calculations and combines the previous week??s data into one report, making it more efficient and less time- consuming.

Each month an analyst needs to execute a data pull for the two prior months. Which of the following is the most efficient function for the analyst to use?
Correct Answer:
B
The most efficient function for an analyst to execute a data pull for the two prior months would be the Date function. This function allows for the manipulation and formatting of date values within a database. Using Date functions, an analyst can dynamically calculate the start and end dates for the previous two months, ensuring that the data pull is accurate and automated without manual intervention.
For example, SQL functions like DATEADD and DATEDIFF can be used to determine the exact range of dates needed for the data pull. These functions can calculate the first and
last day of the previous months relative to the current date, which is essential for monthly reporting and analysis.

✑ Discussions on Stack Overflow suggest using SQL date functions
like DATEADD and DATEDIFF to dynamically extract data for previous months, which supports the use of Date functions12.
✑ The use of Date functions is also recommended for ensuring that the data pull is
not only efficient but also accurate, as it avoids potential errors associated with manual date entry3.
A development company is constructing a new Init in its apartment complex. The complex has the following floor plans:
Using the average cost per square foot of the original floor plans. which of the following should be the price of the Rose Init?
Correct Answer:
D
The correct answer is D. $702,500.
To find the price of the Rose unit, we need to use the average cost per square foot of the original floor plans. The average cost per square foot is calculated by dividing the price by the square footage of each unit type. Using the data from the table, we can do the following:
✑ Jasmine: $345,000 / 1,000 = $345 per square foot
✑ Orchid: $525,000 / 2,000 = $262.5 per square foot
✑ Azalea: $375,000 / 1,500 = $250 per square foot
✑ Tulip: $450,000 / 1,800 = $250 per square foot
The average cost per square foot of the original floor plans is the mean of these four values, which is ($345 + $262.5 + $250 + $250) / 4 = $276.875 per square foot.
To find the price of the Rose unit, we need to multiply the average cost per square foot by the square footage of the Rose unit. The Rose unit has a square footage of 2,535, according to the table. Therefore, the price of the Rose unit is $276.875 x 2,535 = $702,421.875.
Rounding to the nearest whole number, we get $702,500 as the price of the Rose unit.
