A design engineer wants to construct a sample mean chart for controlling the service life of a halogen headlamp his company produces. He knows from numerous previous samples that this service life is normally distributed with a mean of 500 hours and a standard deviation of 20 hours. On three recent production batches, he tested service life on random samples of four headlamps, with these results: Sample Service Life (hours) 1 495 500 505 500 2 525 515 505 515 3 470 480 460 4701. What is the sample mean service life for sample 2? A) 460 hours.B) 495 hours.C) 515 hours.D) 525 hours. 2. What is the mean of the sampling distribution of sample means for whenever service life is in control? A) 250 hours.B) 470 hours.C) 495 hours.D) 500 hours.E) 515 hours. 3. If he uses upper and lower control limits of 520 and 480 hours, on what sample(s) (if any) does service life appear to be out of control?a) sample 1.b) sample 2.c) sample 3.d) both samples 2 and 3.e) all samples are in control.
Answers
Answer:
C) 515 hours.
D) 500 hours
c) sample 3
Step-by-step explanation:
1. Sample 2 mean = x2`= ∑x2/n2= 2060/4= 515 hours
Sample Service Life (hours)
1 2 3
495 525 470
500 515 480
505 505 460
500 515 470
∑2000 2060 1880
x1`= ∑x1/n1= 2000/4= 500 hours
x2`= ∑x2/n2= 2060/4= 515 hours
x3`= ∑x3/n3= 1880/4= 470 hours
2. The mean of the sampling distribution of sample means for whenever service life is in control is 500 hours . It is the given mean in the question and the limits are determined by using μ ± σ , μ±2 σ or μ ± 3 σ.
In this question the limits are determined by using μ ± σ .
3. Upper control limit = UCL = 520 hours
Lower Control Limit= LCL = 480 Hours
Sample 1 mean = x1`= ∑x1/n1= 2000/4= 500 hours
Sample 2 mean = x2`= ∑x2/n2= 2060/4= 515 hours
Sample 3 mean = x3`= ∑x3/n3= 1880/4= 470 hours
This means that the sample mean must lie within the range 480-520 hours but sample 3 has a mean of 470 which is out of the given limit.
We see that the sample 3 mean is lower than the LCL. The other two means are within the given UCL and LCL.
This can be shown by the diagram.

Which fraction has the greatest value?
5/6
1/6
-1/6
-5/6
Answers
Answer:
5/6
Step-by-step explanation:
Answer:
5/6
Step-by-step explanation:
First things first, negative numbers always have a lower value than positive numbers and so -[tex]\frac{1}{6}[/tex] and -[tex]\frac{5}{6}[/tex] is definitely not the answer.
Secondly, imagine that an apple pie is divided into 6 equal parts, and one person gets 5 of the 6 parts and the other got 1 of the 6 parts. Person A would get 4 more parts of the 6 parts than Person B so it shows that [tex]\frac{5}{6}[/tex] is more than [tex]\frac{1}{6}[/tex].
Thus, the fraction with the greatest value is 5/6

A diagonal of a square tile is 10 mm. What is the area of the tile?
Answers
Answer:
A=5×10-5m²
Step-by-step explanation:
Unit Conversion:
d=0.01m
Using the formulas
A=a2
d=2a
Solving forA
A=1
2d2=1
2·0.012=5×10-5m²
Answer:
50 mm²
Step-by-step explanation:
The diagonal divides the square into 2 right triangles, with the diagonal as the hypotenuse.
Using Pythagoras' identity in one of the right triangles.
let s be the side of the square, then
s² + s² = 10² = 100, that is
2s² = 100 ( divide both sides by 2 )
s² = 50 ( take the square root of both sides )
s = [tex]\sqrt{50}[/tex] = [tex]\sqrt{25(2)}[/tex] = 5[tex]\sqrt{2}[/tex]
Thus
area = s² = (5[tex]\sqrt{2}[/tex] )² = 50 mm²

Point A and point B are placed on a number line. Point A is located at -5 and point B is 10 less than point A. Which statement about point B is true?
Answers
Given :
Point A and point B are placed on a number line.
Point A is located at -5 and point B is 10 less than point A.
To Find :
Position of point B in number line.
Solution :
It is given that position of point A is -5 on number line.
So, value of A is -5.
Now, it is given that point B is 10 less than point A.
B = [ -5 + ( -10 ) ] = -15
Therefore, position of point B is [ -5 + ( -10 ) ] = -15 .

The total distance around Wendy's rectangular-shaped bedroom is 260 feet the width of the room is 60 feet what is the area of Wendy's bedroom use the appropriate units of measure
Answers
Answer:
4200 square feet
Step-by-step explanation:
First, find the length of the room
Since the width is 60 feet, both widths add to 120.
Subtract 120 from 260, then divide that by 2:
(260 - 120) / 2
140 / 2
= 70
So, the length is 70 feet.
Use the area formula:
A = lw
A = (70)(60)
A = 4200
So, the area of Wendy's bedroom is 4200 square feet

Solve the equation by completing the square

s=
Please answer this ASAP ! And with step by step expiation please !
Answers
Answer:
s = - 1 ± [tex]\sqrt{7}[/tex]
Step-by-step explanation:
Given
s² + 2s - 6 = 0 ( add 6 to both sides )
s² + 2s = 6
To complete the square
add ( half the coefficient of the s- term )² to both sides
s² + 2(1)s + 1 = 6 + 1
(s + 1)² = 7 ( take the square root of both sides )
s + 1 = ± [tex]\sqrt{7}[/tex] ( subtract 1 from both sides )
s = - 1 ± [tex]\sqrt{7}[/tex]
Thus
s = - 1 - [tex]\sqrt{7}[/tex] , s = - 1 + [tex]\sqrt{7}[/tex]

Step-by-step explanation:
4x + 9 + 79 - x + y = 180
4x - x + y + 79 + 9 = 180
3x + y + 88 = 180
3x + y = 180 - 88
3x + y = 92
y = 92 - 3x
A.) x = 64, y = 50
y = 92 - 3x
(50) = 92 - 3(64)
50 = 92 - 192
50 ≠ - 100
B.) x = 14, y = 152
y = 92 - 3x
(152) = 92 - 3(14)
152 = 92 - 42
152 ≠ 50
C.) x = 23.3, y = 22.1
y = 92 - 3x
(22.1) = 92 - 3(23.3)
22.1 = 92 - 69.9
22.1 = 22.1
D.) x = 14, y = 50
y = 92 - 3x
(50) = 92 - 3(14)
50 = 92 - 42
50 = 50
