Answer:
# Get the number of floors from the user
floors = int(input("How many floors does the hotel have? "))
# Initialize variables to keep track of the number of rooms and occupied rooms
total_rooms = 0
total_occupied_rooms = 0
# Loop once for each floor
for floor in range(floors):
# Get the number of rooms and occupied rooms on this floor
rooms = int(input("How many rooms are on floor " + str(floor + 1) + "? "))
occupied_rooms = int(input("How many of these rooms are occupied? "))
# Update the total number of rooms and occupied rooms
total_rooms += rooms
total_occupied_rooms += occupied_rooms
# Calculate the percentage of rooms that are occupied
occupancy_rate = (total_occupied_rooms / total_rooms) * 100
# Display the results
print("The hotel has a total of", total_rooms, "rooms.")
print("There are", total_occupied_rooms, "occupied rooms.")
print("There are", total_rooms - total_occupied_rooms, "unoccupied rooms.")
print("The occupancy rate is", occupancy_rate, "%.")
Explanation:
This program uses a for loop to iterate once for each floor. On each iteration, it gets the number of rooms and occupied rooms on the floor from the user and updates the total number of rooms and occupied rooms accordingly. Finally, it calculates the occupancy rate and displays the results.
question 5 you are querying a database of keynote speakers to determine who has expertise in zoology. for your project, you only need the first 12 records. what clause should you add to the following sql query?
The correct clause to add to the SQL query to retrieve only the first 12 records is "LIMIT 12". The correct option is c.
What is SQL query?The domain-specific programming language known as SQL is used for managing data stored in relational database management systems or for stream processing in relational data stream management systems.
"LIMIT 12" is the appropriate clause to include in the SQL query to only return the first 12 records. Thus, the whole SQL query would be:
speaker selection from the keynote table LIMIT 12 WHERE knowledge = "zoology"
Just the top 12 entries that satisfy the constraint "expertise = 'zoology'" will be returned by this query.
Thus, the correct option is c.

do we see the original array, or do we see the changes made by the call to the mystery() method? explain briefly why your answer makes sense.
We see the changes made by the call to the mystery() method. This makes sense because when a function modifies an array, it modifies the original array - any changes made to the array are permanent.
What is Array?
An array is a data structure used to store a collection of items. It is typically used to store a collection of elements that all have the same data type, such as integers, floats, strings, or booleans. An array is a way of organizing data that is represented by a collection of elements in a specific order. It makes it easier to access, modify and analyze the data stored in the array. Arrays can be used to store both primitive data types and complex data structures such as objects.

Sands and other coarser are frequently found around river mouths in the subaqueous delta, while finer grained sediments typically settle farther offshore from suspension in the water column or as a result of downslope mass-movement processes.

Software is a set of instructions, data or programs used to operate computers and execute specific tasks. It is the opposite of hardware, which describes the physical aspects of a computer. Software is a generic term used to refer to applications, scripts and programs that run on a device. It can be thought of as the variable part of a computer, while hardware is the invariable part.
The two main categories of software are application software and system software. An application is software that fulfills a specific need or performs tasks. System software is designed to run a computer's hardware and provides a platform for applications to run on top of.
Other types of software include programming software, which provides the programming tools software developers need; middleware, which sits between system software and applications; and driver software, which operates computer devices and peripherals.
Early software was written for specific computers and sold with the hardware it ran on. In the 1980s, software began to be sold on floppy disks, and later on CDs and DVDs. Today, most software is purchased and directly downloaded over the internet. Software can be found on vendor websites or application service provider websites.

These operators have the same semantics (meaning) as their English equivalents. For instance, x > 0 and x 10 only returns True if x is both more than 0 and less than 10. If any of the requirements, i.e., whether the number n is divisible by 2 or by 3, is true, then n% 2 == 0 or n% 3 == 0 is true.
A Boolean value is negated by the not operator, therefore not (x > y) is True if x > y is False, or if x is less than or equal to y. We can combine simpler Boolean expressions to create more complicated Boolean expressions using the three logical operators and, or, and not.

who developed the first alternating current electric system?
The first alternating current (AC) electric system was developed by Nikola Tesla. In the late 19th century.
What is alternating current (AC)?
Alternating current (AC) is a type of electrical current that periodically reverses its direction of flow. In an AC circuit, the flow of electrons alternates back and forth between the two wires of the circuit, creating a waveform that varies with time. The voltage and current in an AC circuit oscillate sinusoidally, with a frequency that is measured in hertz (Hz).
AC power is used to transmit electrical energy over long distances, and is the standard for electrical power distribution in most parts of the world. AC power can be easily transformed into different voltages using transformers, which makes it more efficient and practical for use in power grids. AC power can also be used to drive AC motors, which are commonly used in a wide range of industrial and household applications.
Tesla worked for the inventor and businessman Thomas Edison, who was promoting direct current (DC) as the standard for electrical power distribution. However, Tesla believed that AC was a more efficient and practical system, and in the 1880s he began developing his own AC motors and generators. In 1887, he designed the first AC induction motor, which was a key innovation in the development of AC power systems. Tesla also worked with George Westinghouse, who was a strong proponent of AC power, to promote and develop AC technology. In the late 1890s,
Therefore, AC power systems began to replace DC systems as the standard for electrical power distribution, thanks in large part to the work of Tesla and his collaborators.

during the database design process, dbms selection should be done between logical design stage and physical design stage. question 19 options: true false
False, DBMS selection should be done before the logical design stage in the database design process.
The selection of a Database Management System (DBMS) should be done before the logical design stage of the database design process. This is because different DBMSs have different features, functionalities, and constraints, which can affect the design decisions made during the logical design stage.
During the logical design stage, the focus is on defining the data requirements, entities, relationships, and constraints of the database, without consideration for the specific features of a particular DBMS. Once the logical design is complete, the physical design stage begins, which involves translating the logical design into a physical database schema that can be implemented using a specific DBMS.
Therefore, the selection of a DBMS should be done before the logical design stage, as it can influence the design decisions made during the entire database design process, from the requirements analysis to the physical implementation of the database.
