Answer:
true false
Explanation:
list1 is assigned as Atlanta, Macon, Savanna
list2 is assigned as Atlanta, Macon, Savanna
list3 is assigned as Macon, Atlanta, Savanna
After these assignments,
The program checks if lis1 is equal to list2 and prints the result. Since both lists are equal, it will print true
The program checks if lis1 is equal to list3 and prints the result. Even though both lists contain the same elements, the order is different, it will print false.
If $hourlyWage contains the value 10.00 and $hoursWorked contains the value 20, what value will $bonus contain after the following code is executed?
if ($hourlyWage >= 10 and $hoursWorked <= 20)
$bonus = $25.00;
else
$bonus = $50.00;
Answer:
$25.00
Explanation:
The variable $bonus will contain $25.00 because the if statement has the condition greater than or equals to for hourlyWage and less than or equals to for hoursWorked. Therefore the if condition evaluates to true since we are given in the question that;
$hourlyWage = 10.00 and $hoursWorked = 20
And the statement following the if is executed ignoring the else statement

50 + P0INTS AND BRAIN PROMISED TO FIRST PERSON RIGHT Hoda needs to create a chart that is associated with an Excel spreadsheet. She needs to ensure that if the data in the spreadsheet changes, the chart in her presentation will be updated. Which option must she choose?
Embed the chart.
Link the chart.
Insert the chart as a picture.
This cannot be done.
Answer:
link the chart, itll immediately update
Final answer:
To ensure her presentation chart updates with the spreadsheet, Hoda should link the chart. This enables dynamic updates, unlike embedding or inserting as a picture. Clear legibility in pie graphs and bar graphs is crucial for data presentation.
Explanation:
Hoda needs to choose the option to link the chart to her Excel spreadsheet to ensure that changes in the spreadsheet are reflected in her presentation. Embedding the chart would insert a static copy that does not update with changes to the source data. Inserting the chart as a picture would also result in a static image. Therefore, linking is the option that suits her requirement for a dynamic, updatable chart. When using linked data visualization tools like pie graphs and bar graphs it's crucial to consider presentation clarity and accuracy. For pie graphs, ensuring that the colors and percentages are legible and that smaller sections are visible is important, whereas for bar graphs, having distinguishable colors, a chronological order for data, and clear legibility of numbers and scales is essential.

To rotate the graphic within a frame without rotating the frame;
We use the Selection tool to select the graphic within the frame by clicking within the content grabber. Position the pointer slightly outside any of the four corner handles and drag to rotate the graphic.
It is usually four corner handles not six as written in the question.
Final answer:
To rotate a graphic within a frame without affecting the frame, use the Direct Selection tool or Content Grabber to select the graphic, then hover near a corner handle until the rotation icon appears and drag to rotate.
Explanation:
To rotate the graphic within a graphics frame without rotating the frame itself, most graphic design programs like Adobe InDesign or Illustrator allow you to use the Direct Selection tool or the Content Grabber. Here is a step-by-step method to accomplish this:
Select the graphic frame that contains the image you wish to rotate.Switch to the Direct Selection tool, which allows you to select content within a frame separately from the frame itself.Click on the content grabber (a circle that appears in the center of the selected graphic) to select the graphic inside the frame.Once the graphic is selected, hover slightly inside any of the corner handles until the rotation icon appears. It typically looks like a curved arrow.Click and drag to rotate the graphic independent of its frame.Note that the exact method may vary slightly depending on the software you are using, but the tools and the basic principles will be similar.
What relationship pattern is illustrated in the following schema?

CAR (VehicleID, NumberOfSeats)
TRUCK (VehicleID, CargoCapacity)
VehicleID in CAR must exist in
VehicleID in VEHICLE VehicleID in TRUCK must exist in VehicleID in VEHICLE.
A) Association relationship
B) Intersection relationship
C) Recursive relationship
D) Strong entity relationship
E) Supertype/subtype relationship
Answer:
E) Supertype/subtype relationship
Explanation:
The type of relationship pattern illustrated in the schema below is E) Supertype/subtype relationship
Supertype/subtype relationship is the types of relationship that exist in the form of parent - children relationship in an entity. The supertype entity is the parent while the subtype entity is the child. The supertype entity contains one or more attributes that is common to the subtype entity.
The schema first define the Supertype entity:
VEHICLE (VehicleID, Cost)
CAR (VehicleID, NumberOfSeats)
TRUCK (VehicleID, CargoCapacity)
Then, the following (subtype entity) make reference to the Supertype:
VehicleID in CAR must exist in
VehicleID in VEHICLE
VehicleID in TRUCK must exist in
VehicleID in VEHICLE.
Since the subtype is making reference to supertype, we can say the relationship pattern illustrated in the schema is: Supertype/subtype relationship.
