intro to computer programming chapter 2 discussion questions what is the difference between a scene method and a class method?
Answer:
A scene method, also known as an instance method, is a method that is associated with an instance of a class and operates on the data of that instance. On the other hand, a class method is related to the class itself and works on the class's data. In other words, a class method is a method that is called on the course rather than on an instance of the class. The critical difference between the two is that a class method operates on the class level, while a scene method operates on the instance level.

the admin at universal containers is setting up permissions for internal sales users. in addition to assigning the salesforce cpq user permission set, for which objects do the users need read, create, edit, delete permissions?
They contain a small group of permissions that are crucial for the safety of Salesforce CPQ data.
We created Access sets to be assigned directly to users without any cloning or modifying, in contrast to the majority of CPQ admins who copy and then edit basic access sets for org users. Users' functional access is increased via permission settings without having to modify their profiles. Depending on the Salesforce edition, users can have several permission sets even if they can only have one profile. Regardless of their profiles, you can assign different sorts of users different permission sets. Regardless of a user's primary job function, you can create permission sets to allow access to logical groupings of people.

The PC, printer, IP phone, and switch control VLAN are all on different VLANs based on the IP addresses and masks provided.
Four sub interfaces on the router are necessary in this circumstance. Finally, we set sub-interfaces to begin our router configuration. We set up sub-interfaces for each VLAN on the port that connects the router and the switch. Additionally, we configured 802.1Q encapsulation using the sub-VLAN interface's number. This suggests that switching between different VLANs can be accomplished using a router and switch with a single physical interface.

A clerk was asked to change a $10 bill. The clerk returned -20/3 nickels, 7 dimes, and 28 quarters.
What do you mean by bill?
A bill is a document that states a specific amount of money that a person owes for goods or services. It may also refer to a legislative document that proposes a law that must be agreed upon by both houses of a legislature before it can become law.
This problem can be solved using the V.E.S.T. approach:
Variables:
N = number of nickels
D = number of dimes
Q = number of quarters
Equation:
N + D + Q = 150
Given Conditions:
D = 9 + N
Q = 21 + D
Substituting the second condition into the first:
N + (9 + N) + (21 + 9 + N) = 150
Simplifying and solving for N:
3N + 30 = 150
3N = 120
N = 40
Substituting the value of N into the second condition:
D = 9 + 40
D = 49
Substituting the values of N and D into the third condition:
Q = 21 + 49
Q = 70
Therefore, the clerk returned 40 nickels, 49 dimes, and 70 quarters.
