Answer:
ifstream inputFile;
inputFile.open("Friends.txt");
Explanation:
Though, the programming language is not stated, questions like this are often from C++.
The first statement defines the ifstream object using the following syntax.
ifstream [object_name]
In this case, the object name is inputFile
So, the syntax becomes
ifstream inputFile;
The next line opens a file using the following syntax.
[object_name].open("Filename")
Here, object_name is inputFile and filename is Friends.txt
So, the open statement becomes
inputFile.open("Friends.txt")

Answer: Goal-oriented analysis
Explanation: Goal-oriented analysis is the analyzing activity for focusing on a specific aim or task to be achieved in a desired manner. This analysis requires a high amount of focus , setting the target or goal and the strength and capability to achieve that objective.
Other options are incorrect because sensitivity analysis is analyzing the sensitivity of any task, what-if analysis considers the changing the values of certain function to check the outcome and goal-seeking analysis is analysis in which the output that is to be achieve is already known.
Thus, the correct answer is goal-oriented analysis.
Answer:
The correct option is pane.setOnMouseClicked((e) -> System.out.println(e.getX() + ", " + e.getY()));
Explanation:
As the complete question is not provided, the complete question is attached herewith.
In order to handle the underlined location the way is to get the position using the MouseClicked event which will be activated when the mouse is clicked and then the values of X and Y position will be printed.
pane.setOnMouseClicked((e) -> System.out.println(e.getX() + ", " + e.getY()));
The other options are not correct as the handle used in them is not defined for this purpose.
Constant will be the answer
