benedictine brewery (mount angel abbey, oregon) has two bottling machines. machine a fills 75% of the bottles. given that the bottles are filled by machine a, 10% are defective. given that the bottles are not filled by machine a (that is, machine ac), 5% are defective. using the theorem of bayes, determine the probability that a randomly sampled bottle was filled by machine a, given that it is defective.
The probability that Machine A filled a randomly selected bottle, given that it is defective, is 2/3 or approximately 0.67.
Let's define the subsequent events:
A: Machine A filled the bottle.
A': The bottle wasn't mechanically filled A (i.e. filled by machine AC).
D: the bottle is defective.
The chance that a randomly selected bottle was filled by machine A, assuming that it is broken, is known as P(A|D). The Bayes theorem provides us with:
P(A|D) = P(D|A)P(A) / P(D)
The following three terms on the right-hand side must be calculated:
P(D|A): the probability that a bottle is flawed given that machine A filled it. 10% of the bottles filled by machine A are reported to be faulty. so P(D|A) = 0.1.
P(A): the previous probability that machine A filled a bottle. There are just two machines, both of which fill bottles., P(A) = P(A') = 0.5.
P(D): the slight possibility that a bottle is flawed. The law of total probability can be used to calculate this:
P(D) = P(D|A)P(A) + P(D|A')P(A') = 0.1 x 0.5 + 0.05 x 0.5 = 0.075
Now we can plug in the values:
P(A|D) = 0.1 x 0.5 / 0.075 = 2/3
Therefore, the probability that Machine A filled a randomly selected bottle, given that it is defective, is 2/3 or approximately 0.67.

What are triangles?In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space). In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle. All triangles are enclosed in a single plane if all of geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Unless when otherwise specified, this article discusses triangles in Euclidean geometry, namely the Euclidean plane.
Extend the segment AB and draw a perpendicular line from B to C.
From the figure we see that:
tan (42) = y / 325 + x
y = tan (42) (325 + x)
Also, tan (70) = y / x
y = tan(70) x
Equating the values of y together we have:
tan (42) (325 + x) = tan(70) x
x = 158.430
Now,
cos (70) = 158.430/h
h = 463.2 ft
Hence, the value of the distance BC across the lake to the nearest foot is 463 ft.

Find three consecutive integers such that the sum of the first and the third is 8 more than the second number.
Answer: Let's call the first integer "x". Then, the second integer would be x + 1, and the third integer would be x + 2.
According to the problem, the sum of the first and the third integer is 8 more than the second integer:
x + (x + 2) = (x + 1) + 8
Simplifying the left side of the equation:
2x + 2 = x + 9
Subtracting x from both sides:
x + 2 = 9
Subtracting 2 from both sides:
x = 7
So the first integer is 7, the second integer is 8, and the third integer is 9. These are three consecutive integers that satisfy the condition in the problem.

in 36 seconds. Formulate an equation to represent the
situation. How long could each be fired alone?
Using equations, the time for the main engine 14.4 seconds and 21.6 seconds for the auxiliary engine
What is the equation to represent the situationLet's call the time each engine takes to consume its allotted fuel supply as "t₁" for the main engine and "t₂" for the auxiliary engine.
From the first piece of information, we know:
t₁ = (2/3)t₂
From the second piece of information, we know that the combined fuel consumption time for both engines is 36 seconds:
t₁ + t₂ = 36
Now we can substitute the first equation into the second:
t₁ + (2/3)t₂ = 36
Combining like terms:
t₂ = 21.6
Finally, substituting t₂ back into the first equation:
t₁ = (2/3)(21.6) = 14.4
So the main engine alone could be fired for 14.4 seconds and the auxiliary engine alone could be fired for 21.6 seconds.

True sampling distribution sample which is proportion to be approximately normal is "Both np and n(1 P) are at least 10".
For the sampling distribution of the sample proportion to be approximately normal, the sample size must be sufficiently large, and the sample proportion must be neither too small nor too large.
Specifically, the sample size multiplied by the sample proportion (np) and the sample size multiplied by one minus the sample proportion (n(1-P)) must both be at least 10. This is known as the "success-failure" condition.
Option b is not entirely accurate, as a sample size greater than 30 is a rule of thumb for the Central Limit Theorem to apply, but it is not a strict requirement for normality.
Option c is incorrect as a sample proportion greater than 0.5 means the distribution is skewed towards one end and not normal.

One option in a roulette game is to bet $15 on red. (There are 18 red compartments, 18 black compartments, and two compartments that are neither red nor black.) If the ball lands on red, you get to keep the $15 you paid to play the game and you are awarded $15. If the ball lands elsewhere, you are awarded nothing and the $15 that you bet is collected. What is the expected value for playing roulette if you bet $15 on red?
The expected value for playing roulette if you bet $15 on red is $6.32
What is probability?Probability is the study of the chances of occurrence of a result, which are obtained by the ratio between favorable cases and possible cases.
The expected value for playing roulette if you bet $15 on red can be calculated as follows:
There are 18 red compartments out of a total of 38 compartments (18 red + 18 black + 2 neither red nor black).
Therefore, the probability of the ball landing on red is 18/38 or 9/19.
If the ball lands on red, you win $15 in addition to keeping your original $15 bet. So your total payout is $30.
If the ball does not land on red, you lose your $15 bet.
Using the formula for expected value, we can calculate the expected value of betting $15 on red as:
Expected value = (probability of winning * payout for winning) - (probability of losing * amount lost)
Expected value = (9/19 * $30) - (10/19 * $15)
Expected value = $270/19 - $150/19
Expected value = $120/19
Therefore, the expected value for playing roulette if you bet $15 on red is $6.32

fill in the blank. counting 67 colonies on a plate with 1ml of the 1:1,000,000 dilution indicates that___bacteria were present in 1ml of the original sample.
By applying the unitary method, counting 67 colonies on a plate with 1ml of the 1:1,000,000 dilution indicates that 67,000,000 bacteria were present in 1ml of the original sample.
The unitary method is a mathematical technique that involves finding a unit value and using it to solve problems. In this case, we need to determine the number of bacteria present in 1ml of the original sample.
The dilution factor represents the ratio of the volume of the original sample to the volume of the diluted sample. In this case, the dilution factor is 1:1,000,000, which means that 1ml of the original sample was diluted with 1,000,000ml of a diluent solution to obtain 1ml of the diluted sample. Therefore, the number of bacteria in the original sample is 1,000,000 times the number of bacteria in the diluted sample.
Now, let's use the colony count to determine the number of bacteria in the diluted sample. We are told that 67 colonies were counted on the plate with 1ml of the 1:1,000,000 dilution. This means that each colony represents the growth of a single bacterium in the diluted sample. Therefore, the number of bacteria in the diluted sample is 67.
Using the unitary method, we can now determine the number of bacteria in 1ml of the original sample. We know that the number of bacteria in the original sample is 1,000,000 times the number of bacteria in the diluted sample. Therefore:
Number of bacteria in original sample = Dilution factor x Number of bacteria in diluted sample
Number of bacteria in original sample = 1,000,000 x 67
Number of bacteria in original sample = 67,000,000
So, the answer is that 67,000,000 bacteria were present in 1ml of the original sample.

What is the error of improved Euler's method?
The error of Improved Euler's Method is that it underestimates the true solution of the differential equation, leading to an inaccurate result.
Improved Euler's Method is used to approximate the solution to a differential equation. The method begins by using the initial value of the function, as well as its derivative at that point. The derivative is then multiplied by a step size, h, and added to the initial value to obtain an estimate of the function at the next point. This estimate is used to calculate the derivative at the new point, which is then multiplied by the same step size and added to the initial value to obtain the next estimate. This process is repeated until the desired solution is obtained. The error of Improved Euler's Method is that it underestimates the true solution of the differential equation, leading to an inaccurate result.

b) The coefficient of variation (CV) for Brand B, is equals to the 2.0%.
c) Brand B, is more consistently produces tablets as advertised.
We have comparing data of consumer groups of vitamin C tablets of two brands. Tablets for each group were selected randomly. Data from above table, For brand A :
Tablets contains the quantity of vitamin C = 500 mg
Sample mean = 250
Standard deviation = 7
For brand B :
Tablets contains the quantity of vitamin C = 250 mg
Sample mean = 500
Standard deviations = 10
Cofficient of variation, CV is statistical parameter and it is the ratio of the standard deviation to the mean. Formula is, Coefficient of Variation (CV)
= (Standard Deviation/Mean) × 100.
a) To calculate the coefficient of variation (CV) for Brand A = (7/250 )×100
= 2.8%
b) To calculate the coefficient of variation (CV) for Brand B = (10/500 )×100
= 2.0%
c) As we see, Cofficient of variation of advertising for brand B is less than brand A. So, Brand B more consistently produces tablets as advertised.
Hence, required brand is brand B.
