¿Cuando un conjunto esta determinado por extensiòn?
- A.
Cuando se tiene una característica de todos sus elementos
- B.
Cuando se conoce a cada uno de sus elementos
Correct Answer
B. Cuando se conoce a cada uno de sus elementosExplanation
Cuando un conjunto está determinado por extensión significa que se conoce a cada uno de sus elementos. En otras palabras, se tiene información específica sobre cada elemento que pertenece al conjunto. Esto contrasta con la determinación por comprensión, donde se describe una característica que deben cumplir los elementos del conjunto, en lugar de conocerlos individualmente. En este caso, la respuesta indica que la determinación se realiza mediante el conocimiento de cada elemento del conjunto.Rate this question:

¿Cuando un conjunto está determinado por comprension?
- A.
Cuando se conoce algunos de sus elementos
- B.
Cuando se tiene una característica de sus elelementos
- C.
Cuando se tiene una característica común de todos sus elementos
Correct Answer
C. Cuando se tiene una característica común de todos sus elementosExplanation
A set is determined by comprehension when it is defined by a common characteristic or property that all its elements possess. This means that the set is formed by selecting elements that share a certain trait or feature. By having this common characteristic, it allows us to identify and determine which elements belong to the set and which do not.Rate this question:

Correct Answer(s)
A. Se nombra con letra mayúscula
C. Sus elementos se agrupan entre llaves
E. Agrupa elementos con una caracteristica común
F. Si sus elementos son letra, estas deberán ser minúsculas
G. Sus elementos se separan por coma.Explanation
The correct answer is a combination of qualities that the word "conjunto" possesses. It is named with a capital letter, its elements are grouped between braces, it groups elements with a common characteristic, if its elements are letters, they should be lowercase, and its elements are separated by commas.Rate this question:

Considera el conjunto A={x/x ∈ N, -5 < x < 8}. Razona ¿Cuales afirmaciones son verdaderas?
- A.
-3 ∈ A
- B.
1 ∈ A
- C.
0 ∈ A
- D.
6 ∈ A
- E.
5 ∈ A
- F.
8 ∈ A
Correct Answer(s)
B. 1 ∈ A
D. 6 ∈ A
E. 5 ∈ AExplanation
The set A is defined as the set of natural numbers x such that -5 < x < 8. The question asks which statements are true.
The statement "1 ∈ A" is true because 1 is a natural number and it satisfies the condition -5 < 1 < 8.
The statement "6 ∈ A" is true because 6 is a natural number and it satisfies the condition -5 < 6 < 8.
The statement "5 ∈ A" is true because 5 is a natural number and it satisfies the condition -5 < 5 < 8.
Therefore, the correct statements are 1 ∈ A, 6 ∈ A, and 5 ∈ A.Rate this question:

REPRESENTA LA OPERACION UNION
- A.
Verdadero
- B.
Falso
Correct Answer
B. FalsoExplanation
The correct answer is "falso" because the phrase "REPRESENTA LA OPERACION UNION" translates to "represents the union operation" in English. The union operation is a mathematical operation that combines two sets to form a new set containing all the elements from both sets. Since the phrase is asking if it represents the union operation, the correct answer would be "falso" (false) if it does not represent the union operation.Rate this question:

Correct Answer
C. DiferenciaExplanation
The correct answer is "diferencia" because it represents the operation of finding the elements that are present in one set but not in another. In other words, it calculates the difference between two sets by removing the common elements and keeping only the unique elements from the first set.Rate this question:

LOS CONJUNTOS SE PUEDEN REPRESENTAR POR:
- A.
EXTENSION Y COMPRENSION
- B.
EXTENSION Y DIAGRAMA DE VENN
- C.
COMPRENSION Y DIAGRAMA DE VENN
- D.
EXTENSION, COMPRENSION Y DIAGRAMA DE VENN
Correct Answer
D. EXTENSION, COMPRENSION Y DIAGRAMA DE VENNExplanation
Los conjuntos pueden ser representados de diferentes maneras, pero las tres formas más comunes son mediante la extensión, la comprensión y el diagrama de Venn.
La representación por extensión consiste en listar todos los elementos del conjunto de manera explícita. Por ejemplo, si tenemos el conjunto de los números pares menores que 10, la representación por extensión sería {2, 4, 6, 8}.
La representación por comprensión consiste en describir las características que deben cumplir los elementos del conjunto. Por ejemplo, si tenemos el conjunto de los números pares, la representación por comprensión sería {x | x es un número par}.
El diagrama de Venn es una representación gráfica que utiliza círculos para mostrar la relación entre conjuntos. Cada círculo representa un conjunto y la intersección de los círculos muestra los elementos que pertenecen a ambos conjuntos.
Por lo tanto, la respuesta correcta es que los conjuntos se pueden representar mediante la extensión, la comprensión y el diagrama de Venn.Rate this question:

The correct answer is 11, 12, 13, 14, 15, 16, 19, 20 y 21. This is because the complement of set A refers to all the elements that are not present in set A. In this case, set A includes the numbers 11, 12, 13, 14, 15, 16, 19, 20, and 21. Therefore, the complement of set A would be all the numbers that are not in this list, which is 11, 12, 13, 14, 15, 16, 19, 20, and 21.Rate this question:

Correct Answer
A. 14, 15, 16, 19, 20, 21Explanation
The correct answer is the set of numbers that are not present in either set A or set B. In this case, the numbers 14, 15, 16, 19, 20, and 21 are not present in either set A or set B, so they are the complement of A U B.Rate this question:

EL CONJUNTO VACIO ES SUBCONJUNTO DE TODOS LOS CONJUNTOS.
- A.
Verdadero
- B.
Falso
Correct Answer
A. VerdaderoExplanation
The statement is true because the empty set is a subset of every set. This means that every element in the empty set is also an element of any other set. Since there are no elements in the empty set, it satisfies the condition of being a subset of all sets. Therefore, the statement is true.Rate this question:

Sí n(A) = 0 entonces [P(A)] = 0
- A.
Verdadero
- B.
Falso
Correct Answer
B. FalsoExplanation
If the probability of event A is zero, it means that event A cannot occur. Therefore, the probability of event A, denoted as P(A), will also be zero. In this case, the statement "Sí n(A) = 0 entonces [P(A)] = 0" translates to "If the number of elements in set A is zero, then the probability of event A is zero." This statement is false because even if the number of elements in set A is zero, the probability of event A can still be non-zero if there are other events that can occur.Rate this question:
