Step-by-step explanation:
The quality-control manager of a large factory is concerned about the number of defective items produced by workers. Thirty workers at the factory agree to participate in a study of three different incentive plans to help reduce the number of defective items produced. The plans will be randomly assigned to the workers so that 10 workers received each plan. The reduction in the number of defective items produced by each worker will be recorded two weeks after the plans are implemented.
Answer:
There is no blocking variable, and incentive plans will be randomly assigned to the workers.
Step-by-step explanation:
The options are missing and they are;
A ) There is no blocking variable, and incentive plans will be randomly assigned to the workers.
B ) There is no blocking variable, and the workers were selected at random.
C) Each incentive plan is a block, and a completely randomized design is not blocked.
D ) Each plan will be randomly assigned to 10 pairs of workers who share a similar characteristic.
E ) The number of workers participating in the study was greater than or equal to 30.
The option that best describes why a completely randomized design is an appropriate design to use in this situation is;
Option A; There is no blocking variable, and incentive plans will be randomly assigned to the workers.
A blocking variable is a variable used by an experimenter or a researcher to block out nuisance variables and test the treatments that are of utmost importance to him.A blocking variable is a continuous variable like weight, age e.t.c. From the question, the treatments, that are the incentive plans, are being randomly assigned to the 30 workers without consideration of specific treatments via blocking variable and as such a completely randomized design would solve that problem.Thus, we can conclude that the reason why a completely randomized design is important to use in this case is because there is no blocking variable and as such the treatments are randomly assigned to the workers.

MY NOTES Two stoves are located 45 feet apart, one giving out]] 4 times as much heat as the other. If you stand at a point on the line between the stoves at a distance x from the less powerful stove, the temperature of the air is given by H(x)=100 + 60 x2 + 240 (45−x)2 . Assume you move back an forth between the two stoves, always at least 4 ft from either stove.
Missing Part of the question:
a) Assume you wish to determine the maximum and minimum temperatures you would experience. the domain to study for the function H(x) would be?
b)The is one critical number for the function on the domain in part a and it is?
c) The maximum temperature you would experience is ?
d) The minimum temperature you would experience is ?
Answer:
a. Domain : [tex]4 \leq x \leq 41[/tex]
b. Critical point: [tex]x = 12.33[/tex]
c. The maximum is 115.09
d. The minimum is 100.62
Step-by-step explanation:
Given
[tex]H(x) = 100 + \frac{60}{x^2} + \frac{240}{(45 - x)^2}[/tex]
Solving (a): The domain of H(x)
From the question, we understand that the distance between the two stores is 45ft
Let the first stove be at point A (0 ft) and
the second stove be at point B (45ft)
Since you move back and forth within 4ft from either stoves, then
Your maximum distance at A is (0 + 4) ft = 4ft
Your minimum distance at B is (45 - 4) ft = 41ft
Hence, the domain is: [tex]4 \leq x \leq 41[/tex]
Solving (b): Critical Value
First, we have to differentiate H(x) w.r.t x
[tex]H(x) = 100 + \frac{60}{x^2} + \frac{240}{(45 - x)^2}[/tex]
Differentiate
[tex]H'(x) = 0 -\frac{120}{x^3} + \frac{480}{(45- x)^3}[/tex]
[tex]H'(x) = -\frac{120}{x^3} + \frac{480}{(45- x)^3}[/tex]
Equate H'(x) to 0
[tex]0 = -\frac{120}{x^3} + \frac{480}{(45- x)^3}[/tex]
Rewrite as:
[tex]\frac{120}{x^3} = \frac{480}{(45- x)^3}[/tex]
Cross Multiply
[tex]480 * x^3 = 120 * (45 -x)^3[/tex]
[tex]480 * x^3 = 120 * (45 -x)*(45 -x) * (45 -x)[/tex]
[tex]480 * x^3 = 120 * (2025 -90x +x^2) * (45 -x)[/tex]
[tex]480 * x^3 = 120 * (91125 -4050x +45x^2 -2025x - 90x^2 - x^3)[/tex]
[tex]480 * x^3 = 120 * (91125 -4050x -2025x+45x^2 - 90x^2 - x^3)[/tex]
[tex]480 * x^3 = 120 * (91125 -6075x-45x^2 - x^3)[/tex]
Divide both sides by 120
[tex]4x^3 =91125 -6075x-45x^2 - x^3[/tex]
[tex]4x^3 +x^3-91125 +6075x+45x^2= 0[/tex]
[tex]5x^3-91125 +6075x+45x^2= 0[/tex]
[tex]5x^3+45x^2 +6075x-91125= 0[/tex]
Divide through by 5
[tex]x^3+9x^2 +1215x-18225= 0[/tex]
Solving for x, we have that
[tex]x\approx \:12.33067[/tex]
[tex]x = 12.33[/tex]
Hence, the critical point is 12.33
Solving (x): Maximum temperature
Here, we simply substitute the endpoints of the domain in [tex]H(x) = 100 + \frac{60}{x^2} + \frac{240}{(45 - x)^2}[/tex]
Let x = 4
[tex]H(4) = 100 + \frac{60}{4^2} + \frac{240}{(45 - 4)^2}[/tex]
[tex]H(4) = 100 + \frac{60}{16} + \frac{240}{(41)^2}[/tex]
[tex]H(4) = 100 + \frac{60}{16} + \frac{240}{1681}[/tex]
[tex]H(4) = 100 + 3.75+ 0.14277215942[/tex]
[tex]H(4) = 103.892772159[/tex]
[tex]H(4) = 103.89[/tex] --- approximated
Let x = 41
[tex]H(41) = 100 + \frac{60}{41^2} + \frac{240}{(45 - 41)^2}[/tex]
[tex]H(41) = 100 + \frac{60}{41^2} + \frac{240}{4^2}[/tex]
[tex]H(41) = 100 + \frac{60}{1681} + \frac{240}{16}[/tex]
[tex]H(41) = 100 + 0.03569303985 + 15[/tex]
[tex]H(41) = 115.03569304[/tex]
[tex]H(41) = 115.04[/tex] ---- approximated
Compare both values: The maximum is 115.09
Solving (d): The minimum temperature
In (b), we have that:
[tex]x = 12.33[/tex] --- critical point
The minimum occurs at this point
Substitute 12.33 for x in [tex]H(x) = 100 + \frac{60}{x^2} + \frac{240}{(45 - x)^2}[/tex]
[tex]H(12.33) = 100 + \frac{60}{12.33^2} + \frac{240}{(45 - 12.33)^2}[/tex]
[tex]H(12.33) = 100 + \frac{60}{12.33^2} + \frac{240}{32.67^2}[/tex]
[tex]H(12.33) = 100 + \frac{60}{152.0289} + \frac{240}{1067.3289}[/tex]
[tex]H(12.33) = 100 + 0.39466180443 + 0.22486039682[/tex]
[tex]H(12.33) = 100.619522201[/tex]
[tex]H(12.33) = 100.62[/tex] --- approximated
Hence, the minimum is 100.62
Carol is going to be away on vacation for a couple of days. She does not know how long she will be gone. Carol, however, knows that $250 will be enough for the caretaker to feed the cats, Rover and Bobo, while she is away.
How many days can the caretaker feed the cats before Carol returns? Explain your reasoning critically.
Answer:
The answer is "$150".
Step-by-step explanation:
Please find the complete question in the attached file.
In this question first, we include the quantity of food that these cats eat daily.
[tex]\to \frac{3}{4}= 0.75\\\\\to \frac{1}{2}= 0.5 \\\\ \to 0.75+ 0.5=1.25[/tex]
They are now able to eat the total of meat we consume on a daily basis, that the food we still eat is 1,25 cans each day, and we must have the full 3 cans.
[tex]\to 1.25 \times 2=2.50[/tex]
2.5 cans and they eat 2.5 cans every 2 years with every other day so we'll have to purchase more meat. So let's go to buy some at our favourite place. 2.5 cans one another day to allow us to give the Bobo leftover .5 a can and open the new Rover can.
We also left this meal 1.25 cans, so that we can give it to them tomorrow. The feed time would not allow them to purchase food as we have the right quantity of food left. But we went for 6 cans in 4 days. Let's figure out how we're going to divide 60 by 4 =15
So we have 15 times 6 now, because that will provide us with the answer [tex]\to 15 \times 6=90[/tex]
We finally find out just how much we pay by 90 cans in 60 days so we will find out what it costs us.
That's the number of cans we get from each purchase and we will divide 90 by 3.
[tex]\to \frac{90}{3}=30[/tex]
They are going to multiply 30 times 5 now, since that is the sum of money to buy.
[tex]\to 30 \times 5=150[/tex]

"Linear regression" is just a fancy word for scatter plots. Scatter plots take place in graphs. The dots or plots are scattered and the way they are scattered means something. If it's going down, it's negative, up it's positive, and if it's scattered, it has no corrolation.
Also, you should have learned this in 9th grade. So, check your notes.
If you don't have it, WRITE IT!!!
To find it in your calculator:
1. Go to "Lists and Spreadsheets"
2. Rename the first column "x" and the second on "y"
3. Write all of your numbers in the right column
1, 5, 3, 7 under the "x"
8.67, 10.50, 9.58, 11.41 under the "y"
4. Move your cursor to an empty cell
4. Click: "MENU" #4 #1 #3
5. Rename the correct rows "x" and "y" and press enter
6. Now you can find "m" and "b"
7. Then move your cursor to an empty cell and click "doc" "insert" #7
8. Find the x-axis and find "x"
9. Find the y-axis and find "y"
10. Now press "MENU" #4 #6 #1
And you found your y=mx+b: y=0.5x+8.2
Now, how much money per hour.
So you've found your m and b but now you have to:
1. Replace y with 15 and solve it
15=0.5x+8.2
-8.2 -8.2
6.8=0.5x
Divide 0.5 on both sides
6.8/0.5=13.6

What is the perimeter of the rectangle?
Answer:
28
Step-by-step explanation:
If the area is 48. 48 divided by 6 is 8 right? Okay then, two sides of the rectangle is going to be 8 and 2 sides of the rectangle is going to be 6.
So, take 8+8 and 6+6 which equal 28.
remember, to find the perimeter you add.
which concludes the answer to be 28.
Answer:
28 units
Step-by-step explanation:
So to find the perimeter, you need to find the other length of the triangle. To find that, let's look at the area that was given. We know that area = L x W. So we have the width and when we divide it by the area we can find the missing length which should be: 48/6=8
So with both the length of 8 and the width of 6, we can find the perimeter is equal to:
Perimeter= 8 + 8 + 6 + 6
Perimeter=28

Step-by-step explanation:
Given parameters:
Length of the board = 44inches
Unknown:
equation to find the shorter piece s = ?
Solution:
let the longer piece = L
Shorter piece = s
s + L = 44 ---- i
Now,
L = s + 6 ----- ii
put L = s + 6 into i;
s + s + 6 = 44
2s + 6 = 44
2s = 44 - 6
2s = 38
