Assume that both inspectors inspect every item and that if an item has no flaw, then neither inspector will detect a flaw.
a. Assume that the probability that an item has a flaw is 0.10. If an item is passed by the first inspector, what is the probability that it actually has a flaw?
b. Assume that the probability that an item has a flaw is 0.10. If an item is passed by both inspectors, what is the probability that it actually has a flaw?
Answers
Answer:
a) 0.011
b) 0.0032
Step-by-step explanation:
first lets say A₁ denotes the event that first inspector detects a flaw and A₂ is event that the law will be detected by the second inspector,
also let B denote the event that an item has a flaw.
a)
Given that;
P(B) = 0.1
so
P(A₁ / B ) = 0.9, P(A₂ / B ) = 0.7
using Baye's rule, the probability that an item has a flaw if it was passed by the first inspector is;
P(B / A₁ⁿ ) = [P(A₁ⁿ / B ) P(B)] / [ P(A₁ⁿ / B ) P(B) + P(A₁ⁿ / Bⁿ ) P(Bⁿ) ]
the probability that the first inspector will not detect the flaw if it actually exist is;
P(A₁ⁿ / B ) = 1 - P(A₁ / B )
= 1 - 0.9
= 0.1
Since there are no false detections, the probability that the first inspector will not detect the flaw, given that item does not have flaws is;
P(A₁ⁿ / Bⁿ ) = 1.0
so the probability that the item has flaw if it was passed by the first inspector is;
P(B / A₁ⁿ ) = [(0.1) (0.1)] / [ (0.1 ) (0.1) + (1.0) (1 - 0.1) ]
= 0.01 / ( 0.01 + 0.9)
= 0.01 / 0.91
= 0.011
b)
Also by Bayes rule, the probability that the item has a flaw if it was passed by both inspectors is;
P(B / A₁ⁿ ∩ A₂ⁿ) = [ P(A₁ⁿ ∩ A₂ⁿ / B) P(B)] / [ P(A₁ⁿ ∩ A₂ⁿ / B) P(B) + P(A₁ⁿ ∩ A₂ⁿ / Bⁿ) P(Bⁿ)]
Now since inspectors function independently, the probability that both inspectors will not detect the flaw if it actually exists is;
P(A₁ⁿ ∩ A₂ⁿ / B) = P(A₁ⁿ / B) P(A₂ⁿ / B)
= ( 1 - 0.9 ) ( 1 - 0.7)
= 0.1 * 0.3
= 0.03
since there are no false detections, the probability that both inspectors will not detect the flaw, given that item does not have a flaw is;
P(A₁ⁿ ∩ A₂ⁿ / Bⁿ) = 1.0
therefore
the probability that the item has a flaw if it was passed by both inspectors is;
P(B / A₁ⁿ ∩ A₂ⁿ) = [(0.03)(0.1)] / [(0.03)(0.1) + (1.0)(1-0.1)
= 0.003 / 0.93
= 0.0032

Universal Claims Processors processes insurance claims for large national insurance companies. Most claim processing is done by a large pool of computer operators, some of whom are permanent and some of whom are temporary. A permanent operator can process 16 claims per day, whereas a temporary operator can process 12 per day, and on average the company processes at least 450 claims each day. The company has 40 computer workstations. A permanent operator generates about 0.5 claim with errors each day, whereas a temporary operator averages about 1.4 defective claims per day. The company wants to limit claims with errors to 25 per day. A permanent operator is paid $64 per day, and a temporary operator is paid $42 per day. The company wants to determine the number of permanent and temporary operators to hire in order to minimize costs.

E. f(x) could have a rate of change equal to 2 and g(x) could have a rate of change of –6.
Answers
Answer:
A and DStep-by-step explanation:
Let the functions be
f(x)= ax + bg(x) = cx + dTheir sum
j(x) = (a+c)x + b+dTheir product
k(x)= (ax + b)(cx + d)The answer optionsA. When added, the sum of the y-intercepts must be 1.
Correct. We see point (0,1) of j(x) on the graph. b+d = 1B. When multiplied, the product of the y-intercepts must be –15.
Incorrect. -15 is the vertex of k(x). The vertex of ax^2 + bx + c is -b/2a. So it has no relation to constants of the functions f(x) and g(x)C. Either f(x) or g(x) has a positive rate of change and the other has a negative rate of change.
Incorrect. It refers to the value of ac. If one of a or c has opposite sign it makes k(x) to open down but it is not as per graph.D. f(x) could have a rate of change equal to 1 and g(x) could have a rate of change of 2.
Correct. As per above statement, both linear equations could be positive as their sum and product is positive from the graphs of j(x) and k(x)E. f(x) could have a rate of change equal to 2 and g(x) could have a rate of change of –6.
Incorrect. It should result in decreasing function of j(x) with slope of -4 but it is increasing as per graph.TABE 11742 Mathematics Practice Test Level M Test 1

tonya bought a blanket for 33.35, a pillow for 11.25, and gloves for 16.75. She paid 60 and the rest she borrowed from her friend. If tonya got 8.65 change from the cashier, how much did she borrow from her friend to pay for all the items
Answers
Lets break this down.
So, if you add up all the money, that would be 61.35. That leaves you with 1.35.
Next, to find how much she payed, you have to think, theres a one dollar bill, 5 dollar bill, 10 dollar bill, and so on.
So if you think about the left over change, and add it to the extra 1.35 it would be 10!
Hence, your answer is 10 dollars.
The money Tonya borrowed from her friend to pay for all the items is $10.
Given that, tonya bought a blanket for 33.35, a pillow for 11.25, and gloves for 16.75. She paid 60 and the rest she borrowed from her friend and she got 8.65 change from the cashier.
We need to find the money she borrowed from her friend to pay for all the items.
What is an equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). Equations can be solved to find the value of an unknown variable representing an unknown quantity.
Let the money paid to the cashier be x.
Now, the total cost of the items=33.35+11.25+16.75
=$61.35
So, x=61.35+8.65
=$70
The money she borrowed from friend=70-60=10
Therefore, the money Tonya borrowed from her friend to pay for all the items is $10.

Let x be the score Fatima received on her fifth test. Set up an equation using x that models this scenario. Solve the equation and state what Fatima earned on her fifth and sixth tests.
Answers
Answer:
Fifth Score = 87
Sixth Score = 95
Step-by-step explanation:
Given
[tex]Average = 85[/tex]
[tex]Scores = 83, 78, 87, 80[/tex]
[tex]Fifth\ score = x[/tex]
[tex]Sixth\ Score = 8 + x[/tex]
Required
Set up an equation
Solve for the fifth and sixth score
Average is calculated as thus:
[tex]Average = \frac{\sum x}{n}[/tex]
[tex]Average = \frac{83 +78 + 87 + 80 + x + 8 + x}{6}[/tex]
Substitute 85 for Average
[tex]85 = \frac{83 +78 + 87 + 80 + x + 8 + x}{6}[/tex]
[tex]85 = \frac{83 +78 + 87 + 80 + 8+ x + x}{6}[/tex]
[tex]85 = \frac{336+ 2x}{6}[/tex]
Multiply both sides by 6
[tex]85 * 6 = 336 + 2x[/tex]
[tex]510= 336 + 2x[/tex]
Solve for 2x
[tex]2x = 510 - 336[/tex]
[tex]2x = 174[/tex]
Solve for x
[tex]x = 174/2[/tex]
[tex]x = 87[/tex]
Hence:
[tex]Fifth\ Score = 87[/tex]
[tex]Sixth\ Score = 87 + 8[/tex]
[tex]Sixth\ Score = 95[/tex]

11 = -3k - 22 -8k what is the value of k?
Answers
Answer:
k = -3
Step-by-step explanation:
Step 1: Write equation
11 = -3k - 22 - 8k
Step 2: Solve for x
Combine like terms: 11 = -11k - 22Add 22 to both sides: 33 = -11kDivide both sides by -11: -3 = kRewrite: k = -3Step 3: Check
Plug in k to verify it's a solution.
11 = -3(-3) - 22 - 8(-3)
11 = 9 - 22 + 24
11 = -13 + 24
11 = 11

A high school race track is composed of a rectangle and two semicircles.
a. If the length "l" of the rectangle is twice as long as the diameter of the semicircles, write a formula for "p," the distance around the track, in terms of the radius "r" of the semicircles.
b. Rewrite the formula from a so the radius of the semicircles is given in terms of the distance around the track. Show your work.
Answers
Answer:
a. [tex] p = 2\pi r + 8r [/tex]
b. [tex] r = \frac{p}{2\pi + 8} [/tex]
Step-by-step explanation:
a. Radius of semicircle (r) = r
Diameter of semicircle (d) = 2r
Length of rectangle (l) = 2*diameter of semicircle = 2*2r = 4r
Distance around the track (p) = circumference of circle + 2(l)
Note: the two semicircles of the track = 1 full circle
Circumference of full circle = πd = π*2r = 2πr
Distance around the track:
p = 2πr + 2(4r)
p = 2πr + 8r
b. Rewriting the formula to make radius, r, the subject of the formula in terms of distance around the track.
[tex] p = 2\pi r + 8r [/tex]
Factor out r
[tex] p = r(2\pi + 8) [/tex]
Divide both sides by (2π + 8)
[tex] \frac{p}{2\pi + 8} = \frac{r(2\pi + 8)}{2\pi + 8} [/tex]
[tex] \frac{p}{2\pi + 8} = r [/tex]
[tex] r = \frac{p}{2\pi + 8} [/tex]
A recent study examined hearing loss data for 1628 U.S. teenagers. In this sample, 337 were found to have some level of hearing loss. News of this study spread quickly, with many news articles blaming the prevalence of hearing loss on the higher use of ear buds by teens. At MSNBC (8/17/2010), Carla Johnson summarized the study with the headline: "1 in 5 U.S. teens has hearing loss, study says." To investigate whether this is an appropriate or a misleading headline, you will conduct a test of significance with the following hypotheses:
Null: π = 0.20 Alternative: π ≠ 0.20
A) Describe what the symbol π stands for in this context.
B) Use the Theory-Based Inference applet to determine a p-value.
C) Based on your p-value is there strong evidence that the proportion of all U.S. teens with some hearing loss is different than 1 in 5 (or 20%)?
D) Using the applet, find a 95% confidence interval for the proportion of U.S. teens that have some hearing loss.
E) What is the margin of error for you confidence interval from part (d) of this question?
F) Based on your confidence interval, is 0.20 a plausible value for the proportion of the population that has some hearing loss? Explain why or why not.
