question 3 which option below describes correct cell referencing to apply conditional formatting to the whole row of a data set rather than a single cell?
The correct cell referencing to apply conditional formatting to the whole row of a data set rather than a single cell is to use the reference "$A:$A" in the "Applies to" field when setting up the conditional formatting rule.
What is data set?A data set is a collection of data that is organized and formatted in a specific way. It typically contains facts, observations, or statistics that are collected through a process of measurement or research. Data sets can be used to answer questions and help make informed decisions. They can be used in a variety of ways such as to identify trends, uncover patterns, and make predictions.
This will apply the formatting rule to the entire row, rather than just a single cell, of the data set. For example, if you wanted to color the entire row of a data set if the value of cell A2 was greater than 10, you would use the reference "$A:$A" in the "Applies to" field, and then set the condition to "Cell Value is greater than 10". This will ensure that the conditional formatting rule is applied to the entire row, instead of just the single cell.

Cindy runs 2 kilometers every morning. She takes 2 minutes for the first 250 meters, 4 minutes for the next 1,000 meters, 1 minute for the next 350 meters, and 3 minutes for the rest.
Cindy’s average speed for the entire run is
meters per minute. One kilometer is the same as 1,000 meters.
Hint:
Answer:
I think the answer is is 500 meters every 2.5 minutes
Explanation:
To solve for this equation you have to take all her times and add them up, and then take her meters and add them. It looks like this: 2+4+1+3 = 10, and then for meters add 250+1,000+350+ 400 = 2,000. Divide all of these numbers by the amount in each or four (because there are four different amounts for meters and time each). So your answer should be 500 every 2.5minutes.
I hope this helps!

a warrant has been issued to investigate a server believed to be used by organized crime to swap credit card information. following the order of volatility, which data should you collect first?
The order of volatility is a concept used in computer forensics that refers to the rate at which a particular type of data loses its values in a system. It is essential to gather data quickly in a forensics investigation because the data could be lost forever if not collected on time. When a warrant is issued to investigate a server believed to be used by organized crime to swap credit card information, the data that should be collected first are those that are most likely to be volatile.
They include the following:Data in the system memory (RAM) should be the first priority. This is because the RAM is a type of volatile memory that loses data when the computer is shut down or restarted. The computer's central processing unit (CPU) stores this data in the RAM, such as passwords, and cached web pages.The temporary files or swap files used by the operating system should be collected next. These files are generated by the operating system when the RAM becomes full, and they contain vital information. They may include things like open network files and documents.The system logs, network information, and event logs should also be collected. The system logs provide information about the system configuration and status. They may contain login details, IP addresses, and system events that could be helpful in the investigation. Event logs contain information about critical system events such as hardware failures, device configuration changes, and security audits. They should also be collected to aid in the investigation.In conclusion, data collection is crucial in forensic investigations. The order of volatility is an essential concept to understand in forensics. RAM should be the first data collected in the investigation because of its volatile nature. The operating system swap files and temporary files should be collected next, followed by system logs, network information, and event logs.

Please lay out your input information separately and label it clearly. You are reviewing a new project and have estimated the following cash flows: Year 0: CF=−165,000 Year 1: CF=63,120;NI=13,620 Year 2: CF=70,800;NI=3,300 Year 3: CF=91,080;NI=29,100 Average Book Value =72,000 Your required return for assets of this risk level is 12%. The company will accept a project that is paid off within 3 years. Should we adopt this new project? Make your decision based on different decision rules (NPV, IRR, payback period, average account return and profitability index).
When making investment decisions, multiple capital budgeting techniques are utilized by various companies to determine which investments to adopt.
Such techniques help in assessing the projects’ value based on the net present value (NPV), the internal rate of return (IRR), profitability index (PI), payback period, and the average accounting rate of return (AAR). Below is a breakdown of the application of the different decision rules to assess whether to accept or reject the new project based on the cash flows provided above.
Net Present Value (NPV)This is the present value of future cash flows minus the initial investment cost. It helps in measuring the amount by which the investment increases or decreases the shareholders’ wealth. If the NPV is positive, then it is profitable to invest in the project.
On the other hand, if the NPV is negative, then the project should be rejected as it will lead to a decrease in shareholders’ wealth.
NPV= CF0+ (CF1/1+r) + (CF2/ (1+r)2)+ (CF3/(1+r)3)NPV= -$165,000 + ($63,120/1.12) + ($70,800/1.125) + ($91,080/1.12)NPV = $3,231IRR.
This is the rate that equates the present value of the project’s cash inflows to the initial cost of investment. If the IRR is greater than the required rate of return, then the project should be accepted. However, if the IRR is less than the required rate of return, the project should be rejected. IRR = 15.4% > 12% Payback Period.
This technique measures the number of years required to recover the initial investment cost. If the payback period is less than the required payback period, then the project should be adopted. However, if the payback period is greater than the required payback period, then the project should be rejected.
PPB = 2 years, 2 months, 21 days < 3 yearsAverage Accounting Return (AAR)This method computes the average annual accounting profit earned over the investment period. If the AAR is greater than the target rate of return, then the project should be accepted.
However, if the AAR is less than the target rate of return, then the project should be rejected.
AAR = (13,620+3,300+29,100) / 3Average Book Value = 72,000AAR = 16.8% > 12% Profitability Index (PI).
This technique measures the ratio of the present value of future cash flows to the initial investment. If the PI is greater than 1, the project should be accepted.
However, if the PI is less than 1, the project should be rejected.
PI = (PV of future cash flows) / (Initial investment)PI = ($3,231+ $70,800+ $91,080) / $165,000PI = 1.59.
Conclusion: From the above analysis, the project should be accepted since all the decision rules used to approve the investment returned positive results. Therefore, the company should adopt the project to increase the shareholders’ wealth.

A variation of the LRU page replacement algorithm known as the ____ replacement policy is implemented with a circular queue.
The "Clock" replacement policy. This policy is implemented with a circular queue and is a variation of the LRU (Least Recently Used) page replacement algorithm.
The Clock replacement policy, also known as the Second Chance algorithm, uses a circular queue to keep track of the pages in memory. When a page needs to be replaced, the algorithm checks the reference bit of the page. If the bit is set to 1, indicating that the page has been recently used, the algorithm gives the page a second chance and moves on to the next page in the queue.
