Which set of polar coordinates describes the same location as the rectangular coordinates (0, -2)
klasskru [66]
Polar coordinates identifie the points of the plane by a distance from the reference point and an angle from a reference direction.

In this case the distance of (0,-2) from the origin is 2 and the anglefrom the x-axis is 180°. So the polar coordinates are (2, 180°)

Find the value of x and y for the equation x+y5 7x+9y=6
Nastasia [14]

Answer:

x = \frac{39}{2}

y = -\frac{29}{2}

Step-by-step explanation:

Given

x + y= 5 --- (1)

7x + 9y = 6 ---- (2)

Required

Find x and y

Make x the subject in (1)

x + y= 5

x = 5 - y

Substitute 5- y for x in (2)

7x + 9y = 6

7(5 - y) + 9y = 6

Open bracket

35 -7 y + 9y = 6

Collect like terms

-7y + 9y = 6   - 35

2y = -29

Divide both sides by 2

y = -\frac{29}{2}

Substitute this for y in x = 5 - y

x = 5 - (-\frac{29}{2})

x = 5 +\frac{29}{2}

L.C.M

x =\frac{10+29}{2}

x = \frac{39}{2}

Un dispositivo de seguridad biométrico erróneamente rechaza la admisión de 1 en 1000 personas autorizadas de una instalación que
Leona [35]

Usando probabilidad condicional, se encuentra que hay una probabilidad de 0.0186 = 1.86% que la persona esta realmente autorizada para ingresar.

------------------

Probabilidad Condicional

P(B|A) = \frac{P(A \cap B)}{P(A)}

En que:

  • P(B|A) es la probabilidad de que ocurra el evento B, dado que A sucedió.  
  • P(A \cap B) es la probabilidad de que ocurran tanto A como B.  
  • P(A) es la probabilidad de que ocurra el evento A.

En este problema:

  • Evento A: Persona rechazada.
  • Evento B: Autorizada.

La probabilidad de una persona ser rechazada es:

  • \frac{1}{1000} = 0.001 de 95% = 0.95(autorizada).
  • \frac{1 000 000 - 1}{1 000 000} = 0.999999 de 5% = 0.05(non autorizadas).

O sea:

P(A) = 0.001(0.95) + 0.999999(0.05) = 0.05094995


La probabilidad de una persona estar autorizada y ser rechazada es:

P(A \cap B) = 0.001(0.95)

¿Cuál es la probabilidad que la persona esta realmente autorizada para ingresar?

P(B|A) = \frac{P(A \cap B)}{P(A)}

P(B|A) = \frac{0.001(0.95)}{0.05094995}

P(B|A) = 0.0186

Probabilidad de 0.0186 = 1.86% que la persona esta realmente autorizada para ingresar.
