Considere un proceso industrial en el que se producen vigas de acero las cuales pueden tener defectos de dureza y peso. En el caso de un defecto en la dureza requiere de un estudio de laboratorio. Sin embargo, de procesos anteriores se sabe que 12% de las vigas no pasan la prueba de dureza, que 7% no pasan la prueba de pesado y que sólo 0.5% no pasan ninguna de las dos pruebas.
Si en el proceso se elige una viga al azar y una medición rápida identifica que no pasa la prueba de dureza, ¿cuál es la probabilidad de que el pesado no sea el correcto?

3. 3 “PRUEBA DE HIPÓTESIS” INTRODUCCIÓN Es evidente que las distribuciones muestrales, vistas en el capítulo anterior, basadas en la teoría de la distribución normal, desarrollan un papel de gran importancia en la inferencia estadística. La inferencia estadística comprende dos partes principales, a saber: la estimación de parámetros y la prueba o docimasia de hipótesis. En este capítulo estudiaremos la segunda de ellas, con el fin de desarrollar métodos y observar su aplicación a problemas corrientes de la vida diaria. La inferencia estadística está basada en el supuesto de tomar muchas muestras, todas con igual probabilidad de ser seleccionadas y a través de una de ellas sabremos algo acerca de la población, mediante el cálculo de estimadores, que nos permitan hacer aseveraciones, incorrectas algunas veces, estableciéndose la probabilidad de error. Este método se basa en la aplicación de técnicas de muestreo, para lo cual se requiere de un buen diseño, además de la aplicación de métodos aleatorios de selección, cuando las probabilidades son iguales para cada elemento de una población. En algunos casos no requieren ser iguales, siempre que se conozcan y sean diferentes a cero. CONTENIDO Conceptos generales, usos y procedimientos de aplicación.

Mark is increasing his exercise routine by running and walking at least 4 miles each day. His goal is to burn a minimum of 1,500 calories from this exercise. Walking burns 270 calories/mile and running burns 650 calories. Could he meet his goal by walking 3 miles and running 1 mile?
Answer:
No
Step-by-step explanation:
1. (270 * 3) + (650 * 1)
2. 810 + 650
3. 1,460 miles. Therefore, by doing this, Mark would have trekked 1,460 miles.
4. 1500 > 1460, so Mark would not meet his goal by doing this.

Answer:
53 and 118
Step-by-step explanation:
Just know that all the angles in a triangle add up to 180 degrees. In the first one, you can tell it is a right triangle by the square in the corner and the other angle is 37. So 180-(37+90)=53
For the second one, it is the same case so 180-(42+20)= 118
Answer:
53 degrees
Step-by-step explanation:
sum of angles in a triangle is 180
a right angle is 90
missing angle is B
180 = 90 + 37 + B
180 = 127 + B
B = 53

Two angles of a quadrilateral measure 110° and 120°. The other two angles are in a ratio of
3:10. What are the measures of those two angles?
Answer:
30, 130
Step-by-step explanation:
sum of internal angles in a quadrilateral is 360.
sum of other two angles
[tex] = 360 - (120 + 110) \\ = 360 - 230 \\ = 130[/tex]

y=3x-5
The measure of two angles are (3x+50) and (4x - 10). What must be true
about the angles if x = 20? What is the sum of their measures?
Answer: The two angles add up to 180 so they are supplementary angles.
The sum of their measures is 180 degrees.
Step-by-step explanation:
Plug in given value for x.
x=20
(3x+50)=
(60+50)=110
110
(4x-10)=
80-10=70
70
There are several true things about these angles you can find from this information but I think you are looking for the answer at top.

Find the distance between points P(9, 5) and Q(8, 2)
to the nearest tenth.
Answer:
3.2!
Step-by-step explanation:
Distance formula
Answer:
distance = 3.2
Step-by-step explanation:
Input Data :
Point 1 (xA, yA) = (9, 5)
Point 2 (xB, yB) = (8, 2)
Objective :
Find the distance between two given points on a line?
Formula :
Distance between two points = √(xB − xA) ^ 2 + (yB − yA) ^ 2
Solution :
Distance between two points = √ (8 − 9)^2 + (2− 5) ^ 2
= √(-1)^2 + (-3)^2
= √1 + 9
= √10
= 3.1623
Distance between the two points is 3.1623
3.1623 rounded to the nearest tenth is 3.2

if 5 bags of sugar with equal weight weigh 35 kg, how many bags of sugar would weigh 56 kg?
Answer:
8 bags
Step-by-step explanation:
If 5 bags equal 35 kg, then each bag will weigh 35/5 or 7 kg. If there are 56 kg and you want to find the number of bags, you divide 56 by 7 and you get 8.

The exterior angles of a pentagon are (m+5)°, (2m+3)°, (3m+2)°, (4m+1)° and (5m+4)° respectively. Find the measure of each angle.
Answer:
Step-by-step explanation:
Sum of exterior angles of any polygon =360°
Sum of exterior angles of polygon = 360°
m + 5 + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360
m + 2m + 3m + 4m + 5m + 5 + 3 + 2 + 1 + 4 = 360 {Combine like terms}
15m + 15 = 360 {Subtract 15 from both sides}
15m = 360 - 15
15m = 345 {Divide both sides by 15}
m = 345/15
m = 23
m + 5 = 23 + 5 = 28°
2m + 3 = 2*23 + 3 = 46 + 3 = 49°
3m + 2 = 3*23 + 2 = 69 + 2 = 71°
4m + 1 = 4*23 + 1 = 92 + 1 = 93°
5m + 4 = 5*23 + 4 = 115 + 4 = 119°
Answer:
see explanation
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
Sum the angles and equate to 360
m + 5 + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360, that is
15m + 15 = 360 ( subtract 15 from both sides )
15m = 345 ( divide both sides by 15 )
m = 23
Then
m + 5 = 23 + 5 = 28°
2m + 3 = 2(23) + 3 = 46 + 3 = 49°
3m + 2 = 3(23) + 2 = 69 + 2 = 71°
4m + 1 = 4(23) + 1 = 92 + 1 = 93°
5m + 4 = 5(23) + 4 = 115 + 4 = 119°
Which of these correctly rearranges the terms in this polynomial so like terms are next to each other
Question is not complete, so i have attached it.
Answer:
B: -2x² - 6x² - 6x + 3x + 3 + 2
Step-by-step explanation:
From the image attached, the given polynomial is;
3 - 6x - 2x² + 3x - 6x² + 2
For like terms to be next to each other, we have to rearrange it as follows;
-2x² - 6x² - 6x + 3x + 3 + 2
Like terms are x² and x, thus they are now arranged next to each other.

4)
Answer:
2nd option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- [tex]\frac{3}{2}[/tex], 0) and (x₂, y₂ ) = (0, [tex]\frac{3}{4}[/tex] )
m = [tex]\frac{\frac{3}{4}-0 }{0+\frac{3}{2} }[/tex] = [tex]\frac{\frac{3}{4} }{\frac{3}{2} }[/tex] = [tex]\frac{1}{2}[/tex] and c = [tex]\frac{3}{4}[/tex] , then
y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{4}[/tex] ( multiply through by 4 to clear the fractions )
4y = 2x + 3 ( subtract 4y from both sides )
0 = 2x - 4y + 3 , that is
2x - 4y + 3 = 0 ← equation of line
