Find the term of the following arithmetic sequence. 15,22 , 29 , 36 ,

76 divided by 4 = 19

19 x 3 = 57

Answer = 57

Responder:

0,1536

0.0256

0.4096

Explicación paso a paso:

Dado que :

p = 0,2

Número de ensayos, n = 4

1 - p = 1 - 0,2 = 0,8

Probabilidad de que 2 sean defectuosos;

Usando la fórmula de distribución binomial:

P (x = 2)

P (x = x) = nCx * p ^ x * (1 - p) ^ (n - x)

P (x = 2) = 4C2 * 0.2 ^ 2 * 0.8 ^ 2

P (x = 2) = 6 * 0,04 * 0,64

P (x = 2) = 0,1536

3 están defectuosos:

P (x = 3) = 4C3 * 0,2 ^ 3 * 0,8 ^ 1

P (x = 3) = 4 * 0,008 * 0,8

P (x = 3) = 0,0256

Probabilidad de que ninguno sea defectuoso:

P (x = 0) = 4C0 * 0.2 ^ 0 * 0.8 ^ 4

P (x = 0) = 1 * 1 * 0,4096

P (x = 0) = 0,4096

Usando la distribución binomial, se encuentra que hay una probabilidad de:

a) 0.1536 = 15.35% que 2 sean defectuosos.

b) 0.0256 = 2.56% que 3 sean defectuosos.

c) 0.4096 = 40.96% que ninguno sea defectuosos.

Para cada objeto, solo hay dos resultados posibles. O está defectuoso o no lo es. La probabilidad de que un objeto sea defectuoso es independiente de cualquier otro ítem, lo que significa que se utiliza la distribución binomial para resolver esta cuestión.

Distribución binomial:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Los parámetros son:

En este problema:

Item a:

Esta probabilidad es P(X = 2), o sea:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{4,2}.(0.2)^{2}.(0.8)^{2} = 0.1536[/tex]

Probabilidad de 0.1536 = 15.35% que 2 sean defectuosos.

Item b:

Esta probabilidad es P(X = 3), o sea:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 3) = C_{4,3}.(0.2)^{3}.(0.8)^{1} = 0.0256[/tex]

Probabilidad de 0.0256 = 2.56% que 3 sean defectuosos.

Item c:

Esta probabilidad es P(X = 0), o sea:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{4,0}.(0.2)^{0}.(0.8)^{4} = 0.4096[/tex]

Probabilidad de 0.4096 = 40.96% que ninguno sea defectuosos.

Answer: 42 1/2

Step-by-step explanation:

We subtract 26 1/6 from 68 1/2. We do this by finding the LCM of 6 and 2. That is 6. We multiply 1/2 by 3/3 to get 3/6. Now, we subtract. 68 - 26 is 42, and 3/6 - 1/6 is 2/6. Our answer is 42 2/6. That can be simplified to 42 1/3.

Answer:

42 1/3

Step-by-step explanation:

Subtract 26 1/6 from 68 1/2 by finding the lowest common denominator (6).

Answer:

1.33 liters of milk are required to fill the jug.

Step-by-step explanation:

With the information provided, you can use a rule of three to find the amount of milk required to fill 1 jug of tea given that Mason used 1/6 of a liter of milk to make 1/8 of a jug of tea:

1/6 f a liter of milk → 1/8 of a jug of tea

           x                ←  1 jug of tea

x=(1/6*1)/1/8

x=(1/6)/(1/8)

x=(1*8)/(6*1)

x=8/6

x=4/3=1.33

According to this, the answer is that 1.33 liters of milk are required to fill the jug.

Answer:

y = 2x + 3

Step-by-step explanation:

( 0, 3) and (-1, 1)

m= (y2 -y1)/ (x2 - x1)

m= (1 - 3)/( -1 - 0)

m = (-2)/(-1)

m = 2

y - y1 = m (x - x1)

y - 3 = 2(x -0)

y - 3 = 2x + 0

y = 2x + 3
