Un joven ha invitado a 6 amigos a comer. después de sentarse él. ¿de cuantas maneras diferentes puede sentarse los amigos?

Answers

Answer 1

Se pueden sentar los 6 amigos de 720 maneras diferentes.

Para resolver este problema, se utiliza el concepto de permutación. Una permutación es una forma de organizar un conjunto de elementos en un orden específico. En este caso, los elementos son los 6 amigos y el orden en que se sientan es importante.

El número de permutaciones de un conjunto con n elementos se calcula con la siguiente fórmula:

n! = n x (n - 1) x (n - 2) x ... x 3 x 2 x 1

En este caso, n = 6, por lo que:

6! = 6 x 5 x 4 x 3 x 2 x 1 = 720

Si no importa el orden en que se sientan los amigos, entonces no se trata de una permutación, sino de una combinación. El número de combinaciones de un conjunto con n elementos tomados de k en k se calcula con la siguiente fórmula:

C(n, k) = n! / (k! x (n - k)!)

En este caso, n = 6 y k = 6, por lo que:

C(6, 6) = 6! / (6! x 0!) = 1

Esto significa que solo hay una forma de elegir 6 amigos de un conjunto de 6 si no importa el orden en que se eligen.

Si algunos de los amigos son indistinguibles (por ejemplo, si son gemelos), entonces el número de formas de sentarlos sería menor.En resumen:

El número de maneras diferentes de sentar a 6 amigos después de que el joven se haya sentado es de 720, suponiendo que el orden en que se sientan es importante.

Answer:

The correct answer is Primo.

Mis hermanos _____________________ la cena en la cocina. a. hacía c. hacíamos b. hacías d. hacían

Answers

Mis hermanos hacian la cena en la concina.
d.) hacian

Right answer:d. hacían

All the options are conjugations of the verb hacer in the imperfect tense. This tense is used to talk about past actions, conditions, or events that occurred regularly or frequently or that were in progress in a moment in the past. Since mis hermanos can be replaced by ellos, which is the subject pronoun that matches the third person plural, we need to choose the conjugation of the verb hacer that also matches this person, which is hacían. Finally:

En ciencia, un patógeno es cualquier grupo de microorganismos vivos capaces de causar enfermedades y daño a su hospedero.

Además, los patógenos son agentes causantes de enfermedades debido a un deterioro de las defensas del hospedero. En este contexto, podemos inferir razonablemente y deducir lógicamente que la descripción precisa de un patógeno oportunista sería un deterioro de las defensas del hospedero para permitir la infección.

Answer:

Si estás al aire libre en el parque Los Glaciares, probablemente tienes frío.

Explanation:

Si estás al aire libre en el parque Los Glaciares, probablemente tienes frío. El parque Los Glaciares is a National Park located in the south of Argentina, in Santa Cruz province. It's really cold because it has glaciers, such as the Perito Moreno which is worldwide famous for its beauty. Since it's full of ice all year long, even though of course it's much colder during the winter, if you go there you're going to feel cold and need to have proper clothes to cope with it.

1. Me gusta el carro que esta lejos. Me gusta _________.

2. Me gustan las computadoras que estan cerca de mi. Me gustan__________.

3. A mi padre le gustan
Las Islas muy lejos de nuestra casa. Le gustan _________.

Answers

Answer 1.

Me gusta el carro que esta lejos. Me gusta ese


This lesson stands for demonstrative adjectives, such as este, ese and aquel. So these adjectives demonstrate a quality about the noun they modify. Here that quality is the location in respect to the speaker or the listener. Here we use ese because the word carro (car) is a masculine and singular noun and ese matches this type of nouns. So ese indicates something more distant, that is, nouns that are further from the speaker but they can be close to the listener.


Answer 2.

Me gustan las computadoras que estan cerca de mi. Me gustan estas


Here we choose estas because it indicates something near to the speaker in space. Since we are talking about computers (computadoras), we are talking in plural form, therefore the form este changes to feminine and plural form as estas, that is, I am talking about these computers (estas computadoras) that are near me.


Answer 3.

A mi padre le gustan  las Islas muy lejos de nuestra casa. Le gustan aquellas


Here we choose aquellas because indicates something that is far away from both the speaker and the listener. Since islas is a feminine and plural noun, we need to use the demonstrative adjectives for it matches feminine and plural nouns. Therefore, my father likes islands that are far away from here.
