One of the assumptions underlying the theory of control charting is that successive plotted points are independent of one another. Each plotted point can signal either that a manufacturing process is operating correctly or that there is some sort of malfunction. Even when a process is running correctly, there is a small probability that a particular point will signal a problem with the process. Suppose that this probability is 0.05. What is the probability that at least one of 10 successive points indicates a problem when in fact the process is operating correctly? What is the probability that at least one of 40 successive points indicates a problem when in fact the process is operating correctly?
Answer:
a) the probability that at least one of 10 successive points indicates a problem when in fact the process is operating correctly is 0.4013
b) the probability that at least one of 40 successive points indicates a problem when in fact the process is operating correctly is 0.8715
Step-by-step explanation:
following how the independence multiplication rule works,
i.e finding p(A)' which is 1 - p(No problem) because what we need is an intersection not a union so;
a) 10 successive points
probability (problem) = 0.05
probability (No problem) = 0.95
required probability = 1 - [probability (No problem)]^10
= 1 - (0.95)^10
= 1 - 0.5987
= 0.4013
the probability that at least one of 10 successive points indicates a problem when in fact the process is operating correctly is 0.4013
b) 40 successive points
probability (problem) = 0.05
probability (No problem) = 0.95
required probability = 1 - [probability (No problem)]^40
= 1 - (0.95)^40
= 1 - 0.1285
= 0.8715
the probability that at least one of 40 successive points indicates a problem when in fact the process is operating correctly is 0.8715

If Ari, Ben and Carol each choose a number at random between 1 to 5, inclusive, what is the probability that all pf them choose different number?
Answer:
12/25
Step-by-step explanation:
If one person chooses a number from 1-5 already, they basically have any choice between 1-5 at their disposal. Therefore, there is not much of a probability for them. If the next individual's number will be different, there will be 4 numbers left. Additionally, this means that the next person (let's say Ben) will have a probability 4/5 since that is if he chooses a different number. There will be 3 numbers remaining, so the last person who picks will have a probability of 3/5.
3/5 and 4/5 are boh probabilities, so multiply them together to get one, which is 12/25.
If the points (-8, 7) and T (6,-3) are on a line segment, find the length of ST.
Answer:
The answer is
2√74 or 17.20 unitsStep-by-step explanation:
The length of w line segment between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
S(-8, 7) and T (6,-3)
The length of ST is
[tex] |ST| = \sqrt{ ({ - 8 - 6})^{2} + ({7 + 3})^{2} } \\ = \sqrt{ ({ - 14})^{2} + {10}^{2} } \\ = \sqrt{196 + 10} \\ = \sqrt{296} \\ = 2 \sqrt{74} \\ = 17.2046505...[/tex]
We have the final answer as
2√74 or 17.20 unitsHope this helps you

A total of 450 tickets were sold for the school play they were either adult tickets or student tickets or student tickets the number of student tickets sold was two times the number of adult tickets sold how many adult tickets were sold
Answer:
150
Step-by-step explanation:
If x is the number of adult tickets sold then an equation for this could be
x+2x=450
which could simplify to
3x=450
you would divide both sides of the equation by 3 to get
x=150

Step-by-step explanation:
Q= Why did Baldwin and McMurdo dislike each other?
Baldwin and McMurdo disliked each other since their very first meeting. They both like Ettie, and, that's where the rivalry begins. He knows that Ettie likes McMurdo more and will obviously choose McMurdo over him. It's pretty clear that Teddy Baldwin is jealous of McMurdo. Baldwin was also very furious when he heard that body master McGinty chose McMurdo over him, who had been loyal to the lodge for years.
I'd add more things, but, honestly, that's all- since I don't like to overexaggerate things. Hope it helps you, all the best!
I need an explanation of this question: the chicago cubs have won more than 100 games
write the inequality
Answer:
x > 100
Step-by-step explanation:
Consider x as "Chicago Cubs".
The alligator sign always points/goes to the number (or food) with the highest value (or bigger meal).
Since Chicago Cubs wins is bigger than 100, you can write the inequality as follows:
x > 100

Is there a rigid transformation taking Rhombus P to Rhombus Q? Explain how you know.
Answer:
There's no rigid transformation
Step-by-step explanation:
The attachment is blank; See attachment for clear picture of rhombus
Required
State if there's a rigid transformation between P and Q
The term rigid transformation implies that there's no change in any two or more given shapes as long as the size is being considered.
Looking at both rhombus, you observe that rhombus P and Q have different dimensions.
So, we can conclude that there's no rigid transformation from rhombus P to Q .

Answer:
The answer is 3.19, someone irrationally deleted my answer previously.
Step-by-step explanation:
Simply substract 2.95 from 18.90 and you will get 15.95
Divide this by 5 to get the price of each and you will get $3.19 which is the correct answer.
subtract 7 9/16 - 4 2/4
Jalen has $10.35 in quarters and nickels he has a total of 99 coins how many of each coins does he have?
Answers:
72 nickels and 27 quarters
========================================
Work Shown:
$10.35 = 1035 cents
q = number of quarters
n = number of nickels
n+q = 99 is the total number of coins. This solves to q = -n+99
25q = value of all the quarters in cents
5n = value of all the nickels in cents
5n+25q = 1035 is the total value in cents
------------------
5n+25q = 1035
5n+25( q ) = 1035
5n+25( -n+99 ) = 1035
5n - 25n + 2475 = 1035
-20n + 2475 = 1035
-20n = 1035-2475
-20n = -1440
n = -1440/(-20)
n = 72
Jalen has 72 nickels
q = -n+99
q = -72+99
q = 27
Jalen has 27 quarters
----------------------
Check:
n+q = 72+27 = 99
5n+25q = 5*72+25*27 = 1035

If the camp counselor wants to make sure no more than 1 teenager in each tent is afraid of spiders, does it seem reasonable for him to randomly assign teenagers to tents? (Round your answer to two decimal places.) If the group of 11 teenagers in the tent is a random sample, then there is a % chance that 2 or more teenagers will be afraid of spiders in any particular tent. This probability is somewhat large Correct: Your answer is correct. , so the camp counselor should not Correct: Your answer is correct. randomly assign teenagers to their tents.
Answer:
YES, there are 88% chances that no more than one of them is afraid of spider.
If there is group of 11 teenager in tent, then there is chance that 2 0r more teenager will be afraid of spider.
Step-by-step explanation:
Let A11 be the number of teenager. We want no more than one teenager in each tent is afraid of spider
P (C11≤1) = P (C11=0) + P (C11=1)
= (11C0) 0.070. (1- 0.07)10 + (11C1). 0.071. (1- 0.07)10-1
= 0.88
= 88 %
Yes, it seems reasonable for him to randomly assign teenagers to tents.
There are 88% chances that no more than one of them is afraid of a spider, remaining are in his favor, and he can randomly assign.
If there is a group of 11 teenagers intent, then there is a chance that two 0r more teenagers will be afraid of a spider.
Probability = P (C11≤2)
= P(C11 = 2) + P (C11=3) + P(C11 =4) + ……
(Probability is somewhat large)
The length of a rectangle is twice its width. If the perimeter ot the rectangle is 42 ft, find its area.
Answer:
x length
y width
2x=y
2x+2y=42/2
x+y=21 x+y=21
x+2x=21
3x=21/÷3
x=7
7+y=21
y=21-7=14
7×14=98 the area of a rectangle
Answer: 98 ft²
Step-by-step explanation:
Length (L) = 2w
width (w) = w
Perimeter (P) = 2L + 2w
42 = 2(2w) + 2w
42 = 4w + 2w
42 = 6w
7 = w
L = 2w
= 2(7)
= 14
Area = L · w
= 14 · 7
= 98
1. Tyler paid $178 to get his car repaired. He was charged $73 for parts and $35 per hour
for labor. How many hours did it take to repair his car?
Answer:
3 hours
Step-by-step explanation:
$178 is the total, so subtract the amount he paid for parts by that. (178-72=105)
Now all you need to do is divide 105 by 35, which gets you to 3
the cost of a mobile is set Rs.18000.If mrs.Sharma purchased it with 13% VAT. how much did she pay for it.
Answer:
Rs.20340
Step-by-step explanation:
Cost of the mobile(without VAT) = Rs. 18000
VAT= 13%*18000
=13/100*18000
=13*180
= Rs.2340
Hence, Cost of the mobile phone with VAT= Rs.18000+ Rs. 2340
= Rs.20340
