This exercise illustrates that poor quality can affect schedules and costs. A manufacturing process has 90 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 90 components, what is the probability that the 90 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:
a) 0.0645 = 6.45% probability that the 90 orders can be filled without reordering components.
b) 0.4062 = 40.62% probability that the 100 orders can be filled without reordering components.
c) 0.9034 = 90.34% probability that the 100 orders can be filled without reordering components
Step-by-step explanation:
For each component, there are only two possible outcomes. Either it is defective, or it is not. The components can be assumed to be independent. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
3% of the components are identified as defective
This means that [tex]p = 0.03[/tex]
a. If the manufacturer stocks 90 components, what is the probability that the 90 orders can be filled without reordering components?
0 defective in a set of 90, which is [tex]P(X = 0)[/tex] when [tex]n = 90[/tex]. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{90,0}.(0.03)^{0}.(0.97)^{90} = 0.0645[/tex]
0.0645 = 6.45% probability that the 90 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?
At most 102 - 100 = 2 defective in a set of 102, so [tex]P(X \leq 2)[/tex] when [tex]n = 102[/tex]
Then
[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{102,0}.(0.03)^{0}.(0.97)^{102} = 0.0447[/tex]
[tex]P(X = 1) = C_{102,0}.(0.03)^{1}.(0.97)^{101} = 0.1411[/tex]
[tex]P(X = 2) = C_{102,2}.(0.03)^{2}.(0.97)^{100} = 0.2204[/tex]
[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0447 + 0.1411 + 0.2204 = 0.4062[/tex]
0.4062 = 40.62% 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?
At most 105 - 100 = 5 defective in a set of 105, so [tex]P(X \leq 5)[/tex] when [tex]n = 105[/tex]
Then
[tex]P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{105,0}.(0.03)^{0}.(0.97)^{105} = 0.0408[/tex]
[tex]P(X = 1) = C_{105,0}.(0.03)^{1}.(0.97)^{104} = 0.1326[/tex]
[tex]P(X = 2) = C_{105,2}.(0.03)^{2}.(0.97)^{103} = 0.2133[/tex]
[tex]P(X = 3) = C_{105,3}.(0.03)^{3}.(0.97)^{102} = 0.2265[/tex]
[tex]P(X = 4) = C_{105,4}.(0.03)^{4}.(0.97)^{101} = 0.1786[/tex]
[tex]P(X = 5) = C_{105,5}.(0.03)^{5}.(0.97)^{100} = 0.1116[/tex]
[tex]P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0.0408 + 0.1326 + 0.2133 + 0.2265 + 0.1786 + 0.1116 = 0.9034[/tex]
0.9034 = 90.34% probability that the 100 orders can be filled without reordering components

A plane is flying to Metro City. The plane started its journey 1275 miles from Metro City.
Write an equation in standard form to represent the situation if the plane travels a hours at 550 mph and b hours at
590 mph.
Which equation is correctly written in standard form to represent this scenario?
0 590a - 550b = 1275
550a +590b = 1275
590a + 550b = 1275
550a - 5906 = 1275
Answer:
550a + 590b = 1275
Step-by-step explanation:
We use the following relation to solve this question:
[tex]v = \frac{d}{t}[/tex]
In which v is the velocity, d is the distance and t is the speed.
In this question, we find the distance, so we use:
[tex]d = v*t[/tex]
A plane is flying to Metro City. The plane started its journey 1275 miles from Metro City.
This means that [tex]d = 1275[/tex].
Write an equation in standard form to represent the situation if the plane travels a hours at 550 mph and b hours at 590 mph.
This means that [tex]v*t = 550a + 590b[/tex].
Which equation is correctly written in standard form to represent this scenario?
[tex]d = v*t[/tex]
1275 = 550a + 590b
550a + 590b = 1275
The indefinite integral can be found in more than one way. First use the substitution method to find the indefinite integral. Then find it without using substitution. Check that your answers are equivalent. 6x^5(x^6-2)dx
Answer:
∫[tex]6x^5(x^6-2)\,dx[/tex] = [tex]\frac{1}{2}(x^6-2)^2+C[/tex]
Step-by-step explanation:
To find:
∫[tex]6x^5(x^6-2)\,dx[/tex]
Solution:
Method of substitution:
Let [tex]x^6-2=t[/tex]
Differentiate both sides with respect to [tex]t[/tex]
[tex]6x^5\,dx=dt[/tex]
[use [tex](x^n)'=nx^{n-1}[/tex]]
So,
∫[tex]6x^5(x^6-2)\,dx[/tex] = ∫ [tex]t\,dt[/tex] = [tex]\frac{t^2}{2}+C_1[/tex] where [tex]C_1[/tex] is a variable.
(Use ∫[tex]t^n\,dt=\frac{t^{n+1} }{n+1}[/tex] )
Put [tex]t=x^6-2[/tex]
∫[tex]6x^5(x^6-2)\,dx[/tex] = [tex]\frac{1}{2}(x^6-2)^2+C_1[/tex]
Use [tex](a-b)^2=a^2+b^2-2ab[/tex]
So,
∫[tex]6x^5(x^6-2)\,dx[/tex] = [tex]\frac{1}{2}(x^6-2)^2+C_1=\frac{1}{2}(x^{12}+4-4x^6)+C_1=\frac{x^{12} }{2}-2x^6+2+C_1=\frac{x^{12} }{2}-2x^6+C[/tex]
where [tex]C=2+C_1[/tex]
Without using substitution:
∫[tex]6x^5(x^6-2)\,dx[/tex] = ∫[tex]6x^{11}-12x^5\,dx[/tex] = [tex]\frac{6x^{12} }{12}-\frac{12x^6}{6}+C=\frac{x^{12} }{2}-2x^6+C[/tex]
So, same answer is obtained in both the cases.
Bianca graphs the data in the table and finds that the trend line is s = 2.2 f + 4.7. Based on the information given, a player who makes 22 free throws in a game should score about how many points? 39 44 53 66
Answer:
s = 53
Step-by-step explanation:
Bianca graphs the data in the table and finds that the trend line is :
s = 2.2 f + 4.7
We need to find the score when there are 22 free thrown in a game. Put f = 22 in the above equation.
s = 2.2(22) + 4.7
= 53.1
pr
s = 53
Hence, there is 53 score when f = 22.

Answer:
430 cm³
Step-by-step explanation:
= 11 × 10 × 2
= 220 cm³
= 10 × 3 × (9-2)
= 210 cm³
= 220 + 210
= 430 cm³
Answer:
430 cubic centimeters
Step-by-step explanation:
Lets start by separating both figures. Start with the one in the back, which is the bigger one.
Given:
Length = 10 cm
Width = 3 cm
Height = 9 cm
This is a rectangle and the volume of a rectangle is L x W x H. Therefore,
Volume = 10 x 3 x 9 = 270 cubic centimeters
Now we move on to the second figure.
Given:
Length = 10 cm (Given from the other rectangle)
Width = 8 cm (We do 11 - 3 since we separated the rectangles)
Height = 2 cm
Using the same formula we get the following.
Volume = 10 x 8 x 2 = 160 cubic centimeters
____
Finally, we add both volumes back since we separated the figures in the beginning.
Volume = 270 + 160 = 430 cubic centimeters
can you please help me
Answer:
what is the selection for the first one???
Step-by-step explanation:
The length of a rectangle is 8 ft longer than twice the width. If the perimeter is 70 ft, find the length and width of the rectangle.
Answer:
9 ft and 26 ft
we will take as x the width, then
P rect. = 2(A+B)
A = 2x + 8 | 2×x, because there is b twice less, and + 8, because there is at 8 longer
B = x
70 = 2(2x + 8 + x)
70-16 = 4x + 2x
54= 6 x
54/6 = 9 => B = 9; A = 2×9+8 = 26

Write an equation of the line that passes through (2, 2) and is parallel to the line y = 7x
I need the equation of the parallel line asp
Answer:
y = 7x - 12
Step-by-step explanation:
Parallel lines have same slope.
y = mx + b
m - > slope & b -> y-intercept
y = 7x
So, slope = 7 & (2 , 2)
y - y1 = m(x -x1)
y - 2 = 7(x - 2)
y - 2 = 7x - 14
y = 7x - 14 + 2
y = 7x - 12
