while transaction != 'Q':

if transaction == 'D':

deposit_amount = float(input("Enter amount to be deposited: "))

balance = deposit(deposit_amount, balance)

print("Current balance is: " + str(balance))

elif transaction == 'C':

check_amount = float(input("Enter amount to process check: "))

if balance >= check_amount:

else:

print("Not enough money!")

else:

print("Invalid input!")

transaction = input("Choose transaction method - D to deposit, C to process the check, Q to quit: ")

On the CallCenterReport worksheet, add formulas that will summarize the issues for the department entered in cell B3. In cell B6

grin007 [14]

Answer:

In cell B6, formula =INDEX(INDIRECT($B$3),A6)

CallCenter Worksheet Details:

The image of the CallCenter Report worksheet for reference to the question asked is attached below.

Explanation:

Firtsly, an absolute reference in Excel refers to a reference that is "locked" so that rows and columns won't change when copied. To do this,we put a $ dollar sign ( =A$1,) before the row coordinate to lock only the row.

A relative reference in Excel is a cell address without the $ sign in the row and column coordinates example A1.

Having known what absolute and relative reference are, we wlil write the below formula in cell B6 that will later be copied to cell B9:

: =INDEX(INDIRECT($B$3),A6)

If the options are:

<span>a. The people communicating don't need to be online at the same time.
b. There is lag time in the communication.
c. The communication occurs in real time.

a is false, you do need to be online to receive the message
b is true, typically you continue only after an acknowledgement
c is true, you wait for acknowledgement that occurs in real time (not necessarily fast though)</span>
