Answer:
def validateCreditCard(x):
if type(x)==str and len(x) == 8:
print("Valid credit card number")
else:
print("Invalid credit card number")
validateCreditCard("43589795")
Explanation:
Run the code on your text editor(vs code, sublime, pycharm ) you will get your desired response. If your input is not of type string and not up to 8 digit you will get the response "invalid credit card number" but if it is of type string and up to 8 digit you will get "Valid credit card number".
But remember python works with indentation so when you are transferring this code to your text editor it will run properly well.
I defined the code using the conventional pattern "def"
After defining the function you create a brackets (x) to accommodate your argument x and end it with a semi colon.
Then i use "if" statement to make sure only string argument and 8 digit value will be accepted to print a "valid credit card". if your argument does not pass the if statement condition it will print out the else statement condition which is "Invalid credit card number"
Finally, you have to call your function and test various values.

John is the JAD project leader
Joint Application Development (JAD) is a process that accelerates the design of information technology solutions. JAD uses customer involvement and group dynamics to accurately depict the user's view of the business need and to jointly develop a solution.
The executive sponsor is the person from the customer's organization who has the ultimate authority to make decisions about the project. The sponsor may be the customer's project leader, the CIO, or, in some cases, the CEO. The facilitator works with the sponsor to get the project started; it is essential, however, that the sponsor make key decisions, not the facilitator.
The executive sponsor has the following responsibilities:
. Accept ultimate authority and responsibility for the functional area to be addressed by the system.
· Resolve business policy conflicts by being the ultimate decision? maker.
· Honor the results of the JAD process.
· Set the vision for the project.
· Ensure the project team has access to and commitment from the right business user experts.
· Communicate customer support and cooperation.
Answer:
The answer is "Option c".
Explanation:
In the given visual basic code, an integer array "Inventory" is declared, that includes 3 elements, that are "357, 126, and 220". In the next line, a call stock function is used, in the function, the array is passed as a parameter and in array parameter, the index value that is "2" is passed. This function use label to print array index value, that is "220". and other options are incorrect that can be described as follows:
- Option a and Option b both are wrong because array indexing always starts with 0 and ends with n-1, and in this array, it will take index value 2, which is not equal to 357 and 126.

Answer:
The networks are intelligent and send packets at the highest speed and most efficiently.
Explanation:
Alcatel-Lucent was founded in 1919, it was a French global telecommunications equipment manufacturing company with its headquarter in Paris, France. Alcatel-Lucent provide services such as telecommunications and hybrid networking solutions deployed both in the cloud and on properties.
Alcatel-Lucent’s High Leverage Network (HLN) increases bandwidth and network capabilities while reducing the negative impact on the environment. This high leverage network can handle large amounts of traffic more efficiently because the networks are intelligent and send packets at the highest speed and most efficiently. HLN are intelligent such that it delivers increased bandwidth using fewer devices and energy.
Generally, when the High Leverage Network (HLN) is successfully implemented, it helps telecommunications companies to improve their maintenance costs, operational efficiency, enhance network performance and capacity to meet the bandwidth demands of their end users.
