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
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

Dave found the blueprint of his house. It shows the hallway is 4 inches long. If the scale factor is 1 inch: 1.25 feet, then what is the length of the hallway in real life?
Answer:
5 feet
Step-by-step explanation:
The scale factor = 1 inch: 1.25 feet
The length of the Hally = 4 inches
The length of the hallway in real life is calculated as:
1 inch = 1.25 feet
4 inches = x feet
Cross Multiply
x feet = 4 × 1.25 feet
x feet = 5 feet
Therefore, the length of the Hallway in real life is 5 feet

How would the equilibrium change if the temperature were increased in
SO2(g) + NO2(9) = NO(g) + S03(g) + heat?
A. Only the reaction rate would change.
B. The equilibrium constant would decrease.
C. The amount of NO and SO3 would increase.
D. The amount of NO2 and SO2 would increase.
Answer:
D. The amount of NO2 and SO2 would increase.
Step-by-step explanation:
This is an exothermic reaction as Heat is among the products. Increasing the temperature would lead to more products in the reaction system. In order for the system to annul this change, more reactants would be formed.
The correct option is;
D. The amount of NO2 and SO2 would increase.

write an equation in slope-intercept form of the line perpendicular to y= -1/5x + 1/4 that passes through the point (3,4)
Answer: y=5x-11
Step-by-step explanation:
y=5x-11 is the equation of the line perpendicular to y= -1/5x + 1/4 that passes through the point (3,4).
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given equation of line is y= -1/5x + 1/4
The slope of the perpendicular line is 5.
We need to find line perpendicular to y= -1/5x + 1/4 that passes through the point (3,4)
4=5(3)+b
-11=b
Hence, y=5x-11 is the equation of the line perpendicular to y= -1/5x + 1/4 that passes through the point (3,4).

Step-by-step explanation:
Two cruise ships leave the same port with a 35° angle between their path. Cruise A is traveling at 18 miles per hour and Cruise B is traveling at 15 miles per hour. If they travel in a straight path, find the distance between the cruise ships after 2 hours
Answer:
[tex]20\:\mathrm{miles}[/tex]
Step-by-step explanation:
After travelling two hours, the two cruise ships form a triangle. One of the legs of this triangle will be the distance Cruise A travelled, and another will be the distance Cruise B travelled. We can find the distance they travel using:
[tex]s=\frac{d}{t}, d=s\cdot t[/tex]
Cruise A is travelling at 18 miles per hour for 2 hours. Therefore, Cruise A has travelled:
[tex]d=s\cdot t=18\cdot 2=36\:\mathrm{miles}[/tex]
Cruise B is travelling at 15 miles per hour for 2 hours. Therefore, Cruise B has travelled:
[tex]d=s\cdot t=15\cdot 2=30\:\mathrm{miles}[/tex]
Because we are given the angle between these legs, we can use the Law of Cosines to find the third leg. The Law of Cosines is given by:
[tex]c^2=a^2+b^2-2ab\cos C[/tex], where [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] are interchangeable. Let [tex]c[/tex] represent the distance between the two cruises. We have:
[tex]c^2=36^2+30^2-2\cdot36\cdot30\cdot \cos 35^{\circ},\\c^2=426.63,\\c\approx \fbox{$20\:\mathrm{miles}$}[/tex](one significant figure).
9514 1404 393
Answer:
20.7 miles
Step-by-step explanation:
The distance that A travels in the same direction as B is ...
(18 mi/h)(2 h)cos(35°) = 29.489 mi
So, the difference in distances in that direction is ...
(15 mi/h)(2 h) -29.489 mi = 0.511 mi
__
The distance A travels in the direction perpendicular to B is ...
(18 mi/h)(2 h)sin(35°) = 20.649 mi
So, the straight-line distance between the ships is the hypotenuse of the right triangle with these distances as legs:
AB = √(0.511² +20.649²) = √426.632 . . . miles
AB = 20.655 miles ≈ 20.7 miles . . . separation after 2 hours
