Answer:

Domain: {-2, 1, 0, 2}

Step-by-step explanation:

You write it down as Domain: {-2, 1, 0, 2}

Here is an example of why:

You can watch that video and you will get a pretty good explanation.

Pretty much, you do not repeat numbers when you name the sets.

HELP PLEASE! What’s the domain and range?

NeX [460]

Answer:

Domain → (-∞, -1)∪(-1, ∞)

Range → (-∞, ∞)

Step-by-step explanation:

Given function is,

$\frac{f(x)}{g(x)}=\frac{x^2+2x-5}{2x+2}$

This function is not defined when the denominator is zero.

2x + 2 = 0

2x = -2

x = -1

Therefore, x = -1 is not in the domain of this function.

And the domain will be,

(-∞, -1)∪(-1, ∞)

For all values of x (except x = -1) we get some output values (value of $\frac{f(x)}{g(x)}$ ).

Therefore, range of the function will be (-∞, ∞).

En la final de un concurso escolar de

Sati [7]

Usando la distribución hipergeométrica, la probabilidad de que los alumnos del colegio A obtengan los dos premios (no hay empates), es: 0.2 = 20%.

<h3>¿Qué es la fórmula de distribución hipergeométrica?</h3>

La fórmula es:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Los parámetros son:

x es el número de éxitos.

N es el tamaño de la población.

n es el tamaño de la muestra.

k es el número total de resultados deseados.

Los valores de los parámetros son:

N = 6, k = 3, n = 2.

La probabilidad de que los alumnos del colegio A obtengan los dos premios (no hay empates), es P(X = 2), por eso:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}$

$P(X = 2) = h(2,6,2,3) = \frac{C_{3,2}C_{3,0}}{C_{6,2}} = 0.2$

V125BC [204]

In finding this value you average lower and upper bound
(0.6+0.82)/2 = 0.71 =0.71 estimated margin of error = distance from estimate point lower/ upper bound This interval will be twice margin error
(0.82-0.6)/2 = 0.11 How far is 0.82 from 0.71 ?? =0.11=11%
