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.
Answer:
The expression is "t[k]".
Explanation:
In the question, it is defined that variable k refers to positive integer and variable t refers to a tuple that holds at least k+1 element. The expression for defining the kth element of t is t[k].
- Where variable t is tuple that collects a sequence of immutable (in-built) Python objects. To define tuple we use the parentheses.
- The main purpose to use tuple in this question is that it cannot be changed.

Explanation:
223.1.17/24 indicates that out of 32-bits of IP address 24 bits have been assigned as subnet part and 8 bits for host id.
The binary representation of 223.1.17 is 11011111 00000001 00010001 00000000
Given that, subnet 1 has 63 interfaces. To represent 63 interfaces, we need 6 bits (64 = 26)
So its addresses can be from 223.1.17.0/26 to 223.1.17.62/26
Subnet 2 has 95 interfaces. 95 interfaces can be accommodated using 7 bits up to 127 host addresses can represented using 7 bits (127 = 27)
and hence, the addresses may be from 223.1.17.63/25 to 223.1.17.157/25
Subnet 3 has 16 interfaces. 4 bits are needed for 16 interfaces (16 = 24)
So the network addresses may range from 223.1.17.158/28 to 223.1.17.173/28
Security/Insider threats.
As much as cloud computing is good for your organization, just know that someone is looking after your data. The cloud provider does everything for you from maintenance to managing security. The bigger picture here is that users are entrusting their data to someone else. Although the work of cloud providers is to ensure that your data is safe, some are not always looking after your best interests.
Cyber-attacks.
Any time your data is stored on the cloud, you are at a higher risk of cyber-attack. Vulnerabilities such as DDoS attacks might occur and this single point of failure is in the cloud. As cloud computing continues to become more sophisticated, so do cyberattacks. As much as the security is right, hackers will go to any lengths to penetrate the systems.
