The motherboard is the part in the computer that allows the computer to function correctly. Without it, none of the computer pieces could interact.

Nina has learned that the motherboard is considered the brain because it enables the computer to function, hence option B is correct.

What is the function of the motherboard?

The circuit board determines the kinds of storage devices, memory modules, and graphics cards (among other expansion cards) that can connect to your PC. It also distributes electricity from your power supply and links all of your hardware to your processor.

The motherboard of the computer contains the central processing unit (CPU), also known as a processor. It executes commands and is sometimes referred to as the computer's brain. You provide the CPU instructions every time you touch a key, click the mouse, or launch an application.

Therefore, the motherboard is considered the brain of the computer.

On the Cities worksheet, click cell F13. The lodging is based on a multiplier by City Type. Some cities are more expensive than others. Insert a VLOOKUP function that looks up the City Type (B13), compares it to the City/COL range (A7:B10), and returns the COL percentage. Then multiply the result of the lookup function by the Total Base Lodging (B5) to get the estimated lodging for the first city. Copy the function from cell F13 and use the Paste Formulas option to copy the function to the range F14:F18 without removing the border in cell F18.

Answers

Answer:

I have found and attached a spreadsheet (cities.xlsx) that matches this question.

First we remember the VLOOKUP sintax:

=VLOOKUP (lookup_value, table_array, col_index_num, [range_lookup])

We need to look up the City Type (B13),

compare it to the City/COL range (A7:B10),

and return the COL percentage (2nd column of City/COL)

so the VLOOKUP function on cell F13 has to be:

=VLOOKUP(B13,$A$7:$B$10,2)

Next, to multiply the result by the Total Base Lodging (B5):

=VLOOKUP(B13,$A$7:$B$10,2) *$B$5

Finally que copy the formula to the F14:F18 cells

Notice the use of $  to make cells static and avoid errors while copying the formulas to different cells.

I have attached the completed spreadsheet as "cities final.xlsx"

Design
Implementation
Planning
Development

Answers

Answer:

The answer to this question is given below in the explanation section.

Explanation:

The correct answer to this question is the planning stage. Because the planning stage represents the development of documents that provide the basis for acquiring the resources and for developing the requirement document. at this stage, you plan about what you are going to develop and how to develop it. At this stage, you come out mainly with two documents i.e. project proposal and requirement document.

Other options are not correct because:

In the project management, after planning, you will start designing the product, and after designing you start developing the product, and at the implementation stage, you implement or deploy the product to the customer or to the client. The requirement document that is developed at the planning stage can be used in the later stages of the project.
