Answer:
La estadística es una rama de las matemáticas aplicadas que se ocupa de la recopilación, evaluación, análisis y presentación de datos o información. El trabajo también utiliza elementos de cognición, psicología, informática y ciencias de sistemas, cálculos numéricos y contribuciones de otras materias que tratan de matemáticas, datos y métodos informáticos intensivos.
El resultado, también llamado estadística, a menudo se presenta en forma numérica en números absolutos, números de frecuencia, números proporcionales, promedios, en tablas con series de tiempo o con otros números comparativos y a menudo también se ilustra en diagramas o figuras. El resultado se usa en parte para mostrar cómo se maneja algo en este momento y en parte como una herramienta para predecir eventos futuros mediante inducción. La estadística se utiliza en muchas disciplinas científicas, desde las ciencias naturales hasta las humanidades, pero también en la política y los negocios.
Think about real-world examples of problems whose solutions do—and do not—scale well. Additionally, think about a problem that is so complex that there is no computational solution to feasibly solve the problem in a reasonable amount of time.
Complete a short written response to the following questions:
1. Identify two real-world examples of problems whose solutions do scale well.
2. Identify two real-world examples of problems whose solutions do not scale well.
3. Identify one problem that is so complex that there is no computational solution to feasibly solve the problem in a reasonable amount of time
Answers
Two real-world examples of problems whose solutions do scale well are:Sorting a large dataset: Algorithms like quicksort and mergesort have time complexity of O(n log n).
This makes them efficient for sorting large datasets, as their running time doesn't increase too much as the dataset grows.Image recognition: Machine learning algorithms like convolutional neural networks can be trained on large datasets of images and can classify new images accurately and quickly. These algorithms scale well because they can handle large datasets and their running time doesn't grow too much as the dataset size increases.Two real-world examples of problems whose solutions do not scale well are:Traveling salesman problem: The problem of finding the shortest route that visits a set of cities and returns to the starting city is known as the traveling salesman problem. The problem is NP-hard, which means that it's difficult to find an optimal solution for large datasets of cities, and the running time of algorithms that solve the problem increases exponentially with the number of cities.

A variation of the LRU page replacement algorithm known as the ____ replacement policy is implemented with a circular queue.
Answers
The "Clock" replacement policy. This policy is implemented with a circular queue and is a variation of the LRU (Least Recently Used) page replacement algorithm.
The Clock replacement policy, also known as the Second Chance algorithm, uses a circular queue to keep track of the pages in memory. When a page needs to be replaced, the algorithm checks the reference bit of the page. If the bit is set to 1, indicating that the page has been recently used, the algorithm gives the page a second chance and moves on to the next page in the queue.

Which of the following is the correct way for writing JavaScript array?
A. var salaries = new Array(1:39438, 2:39839 3:83729)
B. var salaries = new (Array1=39438, Array 2-39839 Array 3=83729)
C. var salaries = new Array(39438, 39839,83729)
D. var salaries = new Array() values= 39438, 39839 83729
Answers
The correct way for writing a JavaScript array is given in option C. var salaries = new Array(39438, 39839, 83729).
Explanation:
In JavaScript, arrays are objects used to store multiple values in a single variable. They can be created using various methods, but the most common way is by using the Array() constructor.
Option A is incorrect as it uses a colon instead of a comma to separate the values in the array, which is not valid syntax in JavaScript.
Option B is also incorrect as it uses an unconventional way of assigning values to the array by using equal and minus signs instead of commas.
Option D is also incorrect as it uses an invalid syntax to assign values to the array by using an equal sign after the Array() constructor and not using commas to separate the values.
Option C is the correct way to create an array in JavaScript, where the values are enclosed in parentheses and separated by commas within the Array() constructor. For example, the code "var salaries = new Array(39438, 39839, 83729);" creates an array called "salaries" with three values: 39438, 39839, and 83729.

With over 500 programming languages in the world, the best way approach to learning languages is to focus on memorizing syntax and structure. Then learn languages with simimlar syntaxes and structures. Group of answer choices True False
Answers
The statement "The best approach to learning programming languages is to focus on memorizing syntax and structure, and then learn languages with similar syntaxes and structures" is False.
While it is important to understand the syntax and structure of programming languages, simply memorizing them without understanding the underlying concepts and principles is not the most effective approach to learning languages. Programming languages are not just about syntax; they have unique features, paradigms, and purposes that go beyond mere syntax.
A better approach to learning programming languages is to focus on understanding fundamental programming concepts and principles that are applicable across different languages. This includes concepts like variables, control structures, functions, data types, and algorithms. By grasping these core concepts, learners can then apply them to different programming languages, regardless of their syntax or structure.
Furthermore, exploring a variety of programming languages, even those with different syntaxes and structures, can broaden a programmer's perspective and enable them to choose the best language for a specific task or problem. Learning different languages helps in understanding different programming paradigms and techniques, fostering flexibility and adaptability in a programmer's skill set.

What are the variables in the program?A variable in programming is a value that can change based on external factors or data that has been supplied to the program. A program typically consists of data that it uses while running and instructions that tell the machine what to execute.
In a computer program, information is stored in variables so that it may be accessed and changed.
They also give us the means to give data a name that is descriptive, making it easier for us and the reader to understand our programs. It can be useful to conceive of variables as data storage units.

crisis-mapping tools collect and analyze data from social media and create instantly available information to respond to a crisis.
Answers
Crisis-mapping tools gather and assess information from social media to provide instantly available information to respond to a crisis. In this way, the information collected from social media could be utilized to determine areas most affected, injured persons, and what relief actions have already been implemented.
Crisis mapping tools have revolutionized disaster response by enabling responders to obtain, process, and distribute data more rapidly and efficiently. These instruments assist responders in determining the most affected regions and enabling them to respond accordingly. In the case of natural calamities such as floods and earthquakes, these tools assist in determining the impact of the disaster on roads, homes, infrastructure, and human life.For instance, the online platform called "Ushahidi," which means "testimony" in Swahili, was used to map crisis reports following the 2010 earthquake in Haiti. The tool was used to gather and categorize crisis data from social media, texts, and emails, providing a real-time view of the situation. It was able to aid rescue workers to locate people in need of help. Crisis mapping tools have become essential in disaster response as it provides the necessary data and information required to mitigate the impact of the crisis.
