Tres maquinas (A,B,C) producen el 40 % , 35% y 25 % respectivamente , del total de las piezas manufacturadas en una fabrica .Los porcentajes de produccion defectuosa de estas maquinas son del 3% 4 % y 5 % respectivamente

Answers

Answer 1

Answer:

  La probabilidad de que la pieza elegida sea defectuosa, P(D), 0.0385

La máquina con mayor probabilidad de haber producido la pieza defectuosa es A

Step-by-step explanation:

Sea D= "la pieza es defectuosa" y N= "la pieza no es defectuosa". La información del problema puede expresarse en el diagrama de árbol adjunto.

Para calcular la probabilidad de que la pieza elegida sea defectuosa, P(D), por la propiedad de la probabilidad total,

P(D) = P(A) · P(D/A) + P(B) · P(D/B) + P(C) · P(D/C) =

= 0.40 · 0.03 + 0.35 · 0.04 + 0.25 · 0.05 = 0.0385

Debemos calcular P(B/D). Por el teorema de Bayes,

P(B/D)= P(B) x P(D/B)   /  P(A) x P(D/A) + P(B) x P(D/B) +P(C) x P(D/C)  

          =        0.35 · 0.04 /     0.40 · 0.03 + 0.35 · 0.04 + 0.25 · 0.05

Calculamos P(A/D) y P(C/D), comparándolas con el valor de P(B/D) ya calculado. Aplicando el teorema de Bayes, obtenemos:

0.012

0.0385

P(A/D)= 0.311

0.014

0.0385

P(B(D)=0.363

0.0125

0.0385

P(C/D)=0.324

Tools of Geometry: Question 10 Quadrilateral ABCD has vertices A = (0, 4), B = (0, 3), C = (3, 0), and D = (3 ,4). Quadrilateral A'B'C'D' is formed when quadrilateral ABCD is reflected over the x-axis. What are the coordinates of quadrilateral A'B'C'D' ? A' = (-4, 0), B' = (-3, 0), C' = (0, 3), and D' = (4, 3) A' = (0, -4), B' = (0, -3), C' = (-3, 0), and D' = (-3, -4) A' = (0, -4), B' = (0, -3), C' = (3, 0), and D' = (3, -4) A' = (0, 4), B' = (0, 3), C' = (-3, 0), and D' = (-3, 4)

Answer:

  (c)  A' = (0, -4), B' = (0, -3), C' = (3, 0), and D' = (3, -4)

Step-by-step explanation:

Reflection over the x-axis negates the y-coordinate only. The appropriate choice is ...

  A' = (0, -4), B' = (0, -3), C' = (3, 0), and D' = (3, -4)

Solve the equation below for y.

12(y−8) = 14y−2

Answers

The answer to the question is: y=-47
Multiply 12 into (y-8)
12y-96 = 14y-2
Then move 96 to the other side which will be
12y=14y-2+96
12y=14y+94
Move the 14y and the sign will be minus
12y-14y=94
-2y=94
Dive negative 2 in both sides
Y= -47

(05.05) Which of the following inequalities matches the graph? (1 point)​

Answers

Answer:  Choice A.   [tex]x \le -7[/tex]

=====================================================

Explanation:

Every point in the shaded region has an x coordinate that is equal to -7 or smaller.

Example points include

(-8, 0)(-10, 2)(-9, -5)

The y coordinate does not matter. All that matters is the x coordinate. The boundary line is the equation x = -7, representing all points that have x coordinate of -7. The solid boundary line says to the reader "any point on this boundary line is part of the shaded region solution set". This inclusion is due to the "or equal to" of the inequality sign.

A company claims that their new bottle holds 25% more laundry soap. If their original container held 80 fluid ounces of soap, how much does the new container hold?

Answers

Answer: The new container folds 100 fluid ounces.

Step-by-step explanation:

Given: A company claims that their new bottle holds 25% more laundry soap.

If original container hold 80 fluid ounces.

Then, Quantity of soap in the new container = 80 fluid ounces + 25% of 80 fluid ounces

= [80+0.25 x 800]  fluid ounces               [ 25% = 0.25]

= 80+ 20= 100 fluid ounces  

Hence, the new container folds 100 fluid ounces.
