Answer: D) Operating Systems manage the computer's random access memory (RAM)

Explanation:

It's not A because all modern computers use some form of an Operating System.

It's not B because some Operating Systems can cost hundreds of dollars.

While C has some truth to it, it's reversed. Operating Systems are there to manage and allocate system resources, and D is the better choice.

On the Direct Marketing worksheet, create appropriate range names for Design Fee (cell B8), Cost Per Ad (cell B9), Total Clicks

Inessa [10]

Answer:

See explanation below

Explanation:

Named ranges are a very important tool in Microsoft Excel. It is used in assigning a name to a particular number of cells. It is great for automation and makes formula much easy to understand and use.

One way to create named ranges is theory the Name Box.

To create named ranges in the design marketing sheet we do this;

1) We click on cell B8 and then navigate to the name box at the top right corner of the sheet just above the column A.

•The name box is where the cell address of any cell that is active is displayed.

•You would see that “B8” is displayed on the name box.

• Double click on the name box and type in the appropriate name, in this case - Design_Fee.

• Press enter and you have your named range.

You do the same for the other named ranges.

Note that: Named ranges must contain letters, numbers or underscore.

I need help with Python. The first image is the code and the 2nd is the output.

The issue arises because the string you are trying to print is not a string, rather a float value. Item1, item2 and item3 are strong values (if you type some alphabets in it and not just numbers), but itemonecost, itemtwocost, and itemthreecost are explicitly type casted to float. In line 22, 23, and 24 you’re trying to print a float, by adding it with the string. One cannot add numbers to string. Rather you can type cast the itemcost to string while printing.

Add str(itemonecost) instead of itemonecost in print statement. Do this for other float variables too.

However do note that there are multiple ways to correct this issue, and I’ve just pointed one out.
