This exercise illustrates that poor quality can affect schedules and costs. A manufacturing process has 70 customer orders to fill. Each order requires one component part that is purchased from a supplier. However, typically, 3% of the components are identified as defective, and the components can be assumed to be independent.
Required:
a. If the manufacturer stocks 70 components, what is the probability that the 70 orders can be filled without reordering components?
b. If the manufacturer stocks 102 components, what is the probability that the 100 orders can be filled without reordering components?
c. If the manufacturer stocks 105 components, what is the probability that the 100 orders can be filled without reordering components?
Answer:
Step-by-step explanation:
a) This is a binomial distribution.
p = probability it is defective = 3% = 0.03, q = 1 - p = 1 - 0.03 = 0.97
This is a binomial distribution is given by the formula:
[tex]P(x)=C(n,x)*p^xq^{n-x}[/tex]
But n = 70
[tex]P(x=0)=C(70,0)*0.03^0*(0.97)^{70}=0.1186[/tex]
b) n = 102. Hence there can be 2 defective components, hence:
[tex]P(X\leq2)=P(X=0)+P(X=1)+P(X=2)=C(102,0)*0.03^0*(0.97)^{102}+C(102,1)*0.03^1*(0.97)^{102-1}+C(102,2)*0.03^2*(0.97)^{102-2}=0.0447+0.1441+0.2204=0.4062[/tex]
c) n = 105, there can be 5 defective products:
[tex]P(X\leq2)=P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)+P(X=5)=C(102,0)*0.03^0*(0.97)^{102}+C(102,1)*0.03^1*(0.97)^{102-1}+C(102,2)*0.03^2*(0.97)^{102-2}+C(102,3)*0.03^3 *(0.97)^{102-3}+C(102,4)*0.03^4*(0.97)^{102-4}+C(102,5)*0.03^5*(0.97)^{102-5}=0.0447+0.1411+0.2204+0.2273+0.174+0.1054=0.913[/tex]

Which expression is equivalent to 3/5 divided by 7/9
Answer:
Step-by-step explanation:
its 27/35, so 27/1 * 1/35
The equivalent expression is obtained by changing the division sign to multiplication and taking the reciprocal of the denominator. Hence, we have 3/5 × 9/7 = 27/35
Denominator = 7/9Numerator = 3/5Reciprocal of denominator = 1 ÷ 7/9 = 9/7
Therefore, change the division operator to multiplication and use the reciprocal of the denominator.
3/5 ÷ 7/9 = 3/5 × 9/7
Hence, we have 3/5 × 9/7 = 27/35.

In a population of 9500 subjects, 72% possess a certain characteristic. In a sample of subjects selected from this population, possess the same characteristic. How many subjects in the population and the sample, respectively, possess this characteristic
This question is Incomplete
Complete Question
In a population of 9500 subjects, 72% possess a certain characteristic. In a sample of 400 subjects selected from this population, 73% possess the same characteristic. How many subjects in the population and the sample, respectively, possess this characteristic?
Answer:
Population = 6840 subjects
Samples = 292 subjects
Step-by-step explanation:
In a population of 9500 subjects, 72% possess a certain characteristic.
The number of subjects in the population with this characteristics =
9500 × 72%
= 6840 subjects
In a sample of 400 subjects selected from this population, 73% possess the same characteristic.
The number of subjects in this sample with this characteristics is :
400 subjects × 73%
= 292 subjects
6840 subjects in the population posses this characteristic, while 288 subjects in the sample posses this characteristic
The given parameters are:
[tex]\mathbf{n = 9500}[/tex] --- population
[tex]\mathbf{x = 400}[/tex] -- sample size
[tex]\mathbf{p =72\%}[/tex] ---- the proportion
The number of subjects that posses the characteristics is simply the average of the sample or the population.
For the population, the average is calculated as:
[tex]\mathbf{\mu =np}[/tex]
So, we have:
[tex]\mathbf{\mu =9500 \times 72\%}[/tex]
[tex]\mathbf{\mu =6840}[/tex]
This means that:
6840 subjects in the population posses this characteristics
For the sample, the average is calculated as:
[tex]\mathbf{\bar x=px}[/tex]
So, we have:
[tex]\mathbf{\bar x=72\%\times 400}[/tex]
[tex]\mathbf{\bar x=288}[/tex]
This means that:
288 subjects in the sample posses this characteristics

Which graphs cannot represent a proportional relationship?
Answer:
B and C
Step-by-step explanation:
A linear graph, that is a graph showing a straight line connecting the points plotted, shows a proportional relationship between two variables quantities if it cuts across the point of origin at (0, 0).
Graph A represents a proportional relationship between x and y variables, because the line that connects the points on the graph is a straight line, and also intercepts at (0, 0).
Graph B is a straight line graph, however, it does not intercepts the point of origin (0, 0). Graph B cannot represent proportional relationship.
Graph C is not a linear graph. If you try connecting the points together by drawing a line, the line would not be a straight line. Also, the line of the graph does not intercept at (0, 0). Therefore, it is safe to conclude that graph C does not represent a proportional relationship.
Graph D is a straight line graph. The rate of change between any two points on the lines of both graphs would be constant and the same all through, as the line of the graph intercepts at the point of origin, (0, 0). This connotes a proportional relationship.

local bowling alley charges each person $5.25 per game bowled and $3.50 to rent a pair of bowling shoes. The bowling alley also offers food
specials. Currently, bowlers can purchase a super pizza deal, which includes a large pizza and a pitcher of soda, for only $15.50.
Five friends decide to go bowling. Each friend bowls two games and rents a pair of bowling shoes. They also buy one super pizza deal to
share.
• What is the total cost (in dollars) for the five friends to rent shoes, bowl two games, and purchase a super pizza deal? Explain or show
your work.
• If the five friends split the total cost so each one pays the same amount of money, how much does each friend pay (in dollars)?
Answer:
1. $85.50
2. $17.10
Step-by-step explanation:
1. 5.25 x 10=52.5:cost for all games total.
3.50 x 5=17.5: cost for all shoes total.
15.50: cost for super pizza deal.
Add it all together.
52.5 + 17.5 +15.50= 85.5
2. 85.5 Divided by 5 = 17.1
Xfinity claims that the performance package for the internet will get you a download speed of 100Mbps. In reality, each person who pays for that package has a slightly different internet speed. For a large data set of performance internet customers, the mean internet speed is 100Mbps, with extended deviation of 8Mbps. As soon as that the internet speeds in the data set can be modeled by a normal distribution.
What percent of Performance Package internet customers would be expected to have internet speeds between 84Mbps and 116Mbps? Be sure to also explain your process of getting the answer. Also, please show your work.
Answer: 95%
Step-by-step explanation:
mean = 100, standard deviation (sd) = 8
mean ± 1 sd = z-score of 1 which is 68%
100 ± 8 = 92 to 108
mean ± 2 sd = z-score of 2 which is 95%
100 ± 2(8) = 84 to 116
mean ± 3 sd = z-score of 3 which is 99.7%
100 ± 3(8) = 76 to 124
The internet speeds are between 84 and 118 which is 2 standard deviations from the mean, which is 95% of their internet customers.

According to the Alternate Exterior Angles Theorem, "when two lines are cut by a transversal, the resulting alternate exterior angles are congruent."
This means that the two expressions above are to be set equal to each other because they are representative of two alternate exterior angles, which are congruent:
[tex]4x-11=2x+25[/tex]
Add [tex]11[/tex] to both sides of the equation:
[tex]4x=2x+36[/tex]
Subtract [tex]2x[/tex] from both sides of the equation:
[tex]2x=36[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]2[/tex]:
[tex]x=18[/tex]

[tex]61=61[/tex]
It's correct!
Answer:
18
Step-by-step explanation:
From the given figure, we can see that angle (4x - 11) will be equal to angle 1 since they are corresponding angles
We notice that angle 1 is vertically opposite to angle (2x + 25)
Hence,
angle (4x - 11) = angle 1 = angle (2x + 25)
So, we can say that angle (4x - 11) = angle (2x + 25)
Now, solving for x:
4x - 11 = 2x + 25
2x = 36
x = 18
