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

Mean
can someone help me?
Answer:
7.5
Step-by-step explanation:
3 + 9 + 13 + 8 + 10 + 2 = 45
There are 6 numbers so we divide 45 by 6
45/6 = 7.5
Write in point-slope form an equation of the line that passes through the point (3,0) with slope 23.
Answer:
[tex]y-0=23(x-3)[/tex]
Step-by-step explanation:
Point-slope form: [tex]y-y_1=m(x-x_1)[/tex] when the given point is [tex](x_1,y_1)[/tex] and [tex]m[/tex] is the slope
[tex]y-y_1=m(x-x_1)[/tex]
Plug in the point
[tex]y-0=m(x-3)[/tex]
Plug in the slope
[tex]y-0=23(x-3)[/tex]

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)
9514 1404 393
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)

midpoints. AC=50, CE=60, and
BD=35
DF=[?]
Answer:
25
Step-by-step explanation:
The smaller triangle is constructed by joining the 3 midpoints. Every line in that smaller triangle is parallel and 1/2 the size of the line not joined by the 2 given midpoints.
In this case 1/2 AC = 1/2 * 50 = 25
The length of DF = 25

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

Answer:
5. 216, 1416
6. 448.5 g
Step-by-step explanation:
5.
Price of 1 item: 1200
GST = 18%
18% of 1200 =
= 0.18 * 1200
= 216
Amount of tax: 216
Total price = original price + GST
Total price = 1200 + 216 = 1416
6.
Weight of 1 item: 17 1/4 g
Weight of 26 items = 26 * 17 1/4 g
26 * 17.25 g = 448.5 g

Answer:
Perpendicular H = 5.244 m (Approx)
Step-by-step explanation:
Given:
Hypotenuse = 9.4 m
Base = 7.8 m
Find:
Perpendicular H
Computation:
Perpendicular H = √Hypotenuse² - Base²
Perpendicular H = √9.4² - 7.8²
Perpendicular H = √Hypotenuse² - Base²
Perpendicular H = 5.244 m (Approx)

Luke wants to reduce the area of his rectangular garden by one-fourth. The expression 1/4 lw can be used to represent this change. What is another way to write this expression?
Answer:
lw/4
Step-by-step explanation:
Area of a rectangle = length × width
= l × w
Area of a rectangle = let
reduce the area of his rectangular garden by one-fourth
= 1/4 * lw
= 1/4lw
What is another way to write this expression?
Another way to write the expression is
= 1/4 * lw
= lw / 4

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?
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.

2/5k - 3/5 + 1/10k ?
Answer:
Since it is not an equation u wont get a numerical value
so basically its just fraction addition and subtraction
which is ((2/5)-(3/5)+(1/10))k
so answer is (-1/10)k
Step-by-step explanation:
[tex] \frac{2}{5} k \: - \frac{3}{5} + \frac{1}{10} k[/tex]
[tex] \frac{4}{10} k + \frac{1}{10} k - \frac{3}{5} [/tex]
[tex] \frac{5}{10} k - \frac{3}{5} [/tex]
