Utilizando la distribución binomial, la probabilidad de resolver un problema de n problemas propuestos, es p^n.

<h3>¿Cuál es la fórmula de distribución binomial?</h3>

La fórmula es:

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

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

Los parámetros son:

  • x es el número de éxitos.
  • n es el número de intentos.
  • p es la probabilidad de éxito en un solo intento.

La probabilidad de que todos los problemas sean resolvidos es dada por P(X = n), asi:

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

P(X = n) = C_{n,n}.p^{n}.(1-p)^{n-n}

P(X = n) = p^n

Given: a-b= c-d, b=d-1, c=6; prove: a=5
Brut [27]

Given :

a-b = c-d    ...1)

b = d-1       ...2)

c = 6

To Prove :

a = 5

Solution :

Adding equation 1 and 2, we get :

(a-b) + (b) = (c-d) + (d-1)

a = c -1   ...3)

Putting given value of c = 6 in above equation, we get :

a = 6 - 1

a = 5

Hence, proved.

There are 6 picas in 1 in. If a line of type is 3 3/4in long. What is this picas in length?
scoray [572]

Answer:

3 3/4 in length is equal to 22.5 picas

Step-by-step explanation:

If there are 6 picas in 1 in, then in 3 3/4 in, we will first take this to decimal form, which is

3.75 in

Therefor 3.75 in = 6 picas × 3.75 = 22.5 pisca

Show that the function f(x)= integral from x to 3x 1/t ft is constant on the interval (0, positive infinity)
jarptica [38.1K]
\int\limits^{3x}_x { \frac{1}{t} } \, dt
integrate to get
[ln|t|]^{3x}_x=ln|3x|-ln|x|=ln| \frac{3x}{x}| =ln |3|=ln(3)
this only is true when x>0
when x turns negative, we get -ln(3) because of math
