Consider two digital fuel pumps A and B that could be used in a single gas station. Pump A has a mean effective process time of 4 minutes with squared-coefficient of variation of 0.5. Pump B has a mean effective time of 3 minute with squared-coefficient of variation of 5. Assume that the arrival rate of cars is 0.2 car per minute with squared-coefficient of variation of 1. Which pump will have a longer average cycle time? (Hint: the number of machines, m, is 1.)
Answers
Therefore, Pump B will have a longer average cycle time compared to Pump A.
To determine which pump will have a longer average cycle time, we need to calculate the cycle time for each pump based on the given information and compare the results. The cycle time for a single-server system can be calculated using Little's Law: Cycle Time = (1 / Arrival Rate) * (1 / (1 - Utilization))
Given:
Arrival Rate = 0.2 car per minute
Squared-Coefficient of Variation (CV^2) for Arrival Rate = 1
Utilization can be calculated as the product of the mean effective process time and the arrival rate:
Utilization = Mean Effective Process Time * Arrival Rate
For Pump A:
Mean Effective Process Time (A) = 4 minutes
Squared-Coefficient of Variation for Pump A = 0.5
Utilization (A) = 4 * 0.2 = 0.8
For Pump B:
Mean Effective Process Time (B) = 3 minutes
Squared-Coefficient of Variation for Pump B = 5
Utilization (B) = 3 * 0.2 = 0.6
Now, let's calculate the cycle time for each pump:
Cycle Time (A) = (1 / 0.2) * (1 / (1 - 0.8))
= 5 minutes
Cycle Time (B) = (1 / 0.2) * (1 / (1 - 0.6))
= 2.5 minutes

There are 36 coins consist of nickels, dimes, and quarters. There are three fewer quarters than nickels and six more dimes than quarters. How many of each kind of coin is there?
Answers
Answer:
Number of Nickels is 12
Number of Dimes is 9
Number of Quarters is 15
Step-by-step explanation:
Given that there are a total of 36 coins, which consists of nickels, dimes, and quarters.
That is, when we sum the numbers of nickels, dimes, and quarters, we have 36.
Let number of nickels be N
Let number of dimes be D
Let number of quarters be Q
Then
N + D + Q = 36 .................................(1)
- There are three fewer quarters than nickels.
This implies that
N = Q - 3 ..............................................(2)
Or
Q = N + 3 .............................................(3)
- There are six more dimes than quarters.
This implies that
Q = D + 6 .............................................(4)
Comparing (3) with (4), we see that
N + 3 = D + 6
N - D = 6 - 3
N - D = 3 ................................................(5)
Using (3) in (1)
N + D + (N + 3) = 36
2N + D = 36 - 3
2N + D = 33 ..........................................(6)
Solving (5) and (6) simultaneously
From (5): D = N - 3
From (6): D = 33 - 2N
=> N - 3 = 33 - 2N
N + 2N = 33 + 3
3N = 36
N = 36/3 = 12..........................................(7)
Using (7) in (6)
2(12) + D = 33
24 + D = 33
D = 33 - 24
D = 9 ........................................................(8)
Using (7) and (8) in (1)
12 + 9 + Q = 36
21 + Q = 36
Q = 36 - 21 = 15.......................................(9)
Therefore,
Number of Nickels, N = 12
Number of Dimes, D = 9
Number of Quarters, Q = 15

What is the interquartile range (iqr) of the data set represented by this box plot?
Answers
The IQR (interquartile range) of the data set expressed by this box plot is 22 units.
Each number of the data set pictured as a box plot is something the numbers have individually. The lowest number there (the first number), 38, is known as the minimum. The highest number there (the last number), 75, is known as the maximum. The second number there, 45, is known as the lower quartile. The third number there, 50, is known as the median or middle quartile. The fourth number, 67, is known as the higher quartile. In order to find the interquartile range, we need to find the difference between the lower quartile and higher quartile, which means subtracting.
67 (highest quartile)- 45 (lower quartile) = 22 (interquartile range)

A long distance telephone company offer two plans . The deluxe plan cost $30 a month and offers unlimited long distance calling. The economy plan only costs $10 a month, but charges 5 cents per minute for every long- distance call. How many minutes a month can you use for long distance calls and still have money using the economy plan?
Answers
Answer:
399 minutes a month
Step-by-step explanation:
As I understand the question the answer would, in other words, be how many minutes you can long-distance call with the economy plan for under $30.
The unit ratio is 5 cents per minute, which equates to 20 minutes worth of call time for one dollar (100/5).
The economy plan is $20 cheaper than the deluxe plan. $20 spent on long-distance calling gets you 400 mintues, but the question asks for an integer that would still leave remaining money.
Therefore the answer is 399 minutes of long-distance calling, which would leave five unspent cents.
If \( P(B)=0.2, P(A \mid B)=0.9, P\left(B^{\prime}\right)=0.8 \), and \( P\left(A \mid B^{\prime}\right)=0.5 \), find \( P(B \mid A) \). \( P(B \mid A)= \) (Round to three decimal places as needed.)
Answers
P(B∣A) is approximately 0.310, rounded to three decimal places.
To find the probability P(B∣A), we can use Bayes' theorem:
P(B∣A)= P(A) / P(A∣B)⋅P(B)
Given information:
P(B)=0.2
P(A∣B)=0.9
P(B')=0.8 (probability of not B)
P(A∣B′)=0.5 (probability of A given not B)
First, we need to calculate
P(A), the probability of event A. We can use the law of total probability to express P(A) in terms of the probabilities related to B and not B:
P(A)=P(A∣B)⋅P(B)+P(A∣B′)⋅P(B′)
Substituting the given values:
P(A)=0.9⋅0.2+0.5⋅0.8=0.18+0.4=0.58
Now, we can substitute the known values into Bayes' theorem:
P(B∣A)= P(A)/ P(A∣B)⋅P(B)
= 0. 9.0.2 / 0.58
Calculating this expression:
P(B∣A)≈ 0.5 80.18 ≈0.310
Therefore, P(B∣A) is approximately 0.310, rounded to three decimal places.

The ratio of corresponding sides for the given similar triangles is 2/5.
In the given options, the ratio of corresponding sides is provided for each set of similar triangles. Let's analyze each option to determine the correct ratio:
a. 10
This option only provides a single number and does not specify the ratio of corresponding sides. Therefore, it is not the correct answer.
b. 4/5
This option provides the ratio 4/5 for the corresponding sides of the similar triangles. However, the ratio can be simplified further.
To simplify the ratio, we divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 4 and 5 is 1.
Dividing 4 and 5 by 1, we get:
4 ÷ 1 = 4
5 ÷ 1 = 5
Therefore, the simplified ratio is 4/5.
c. 10/85
This option provides the ratio 10/85 for the corresponding sides of the similar triangles. However, this ratio cannot be simplified further, as 10 and 85 do not have a common factor other than 1.
Therefore, the correct ratio of corresponding sides for the given similar triangles is 2/5, as determined in option b.

The required probability of the son with normal vision is 0.50 and for the normal blood clotting is 0.
If mutations is present on one of the X chromosome then it is capable of developing the condition which is called X-linked disorder.Generally men are affected by this disorder because they carry one copy of the X chromosome.If women carry one copy of the chromosome, then it is consider that they are carriers of disease and if they have both the copies affected then they are affected by disorder.Colorblind woman with a normal man is in position to produce 2 carrier females and 2 males colorblind.In the condition of a carrier woman with colorblindness marries a hemophilic man, progeny mentioned below phenotypes are produced:Parent phenotype Carrier woman
Affected man (Hemophilic) (colorblindness)

Total outcome = 100
Favourable outcomes for a son with normal vision is= 50
Probability of a son with normal vision = 50/100

Answers
The total number of seats are 1260 in an auditorium.
The number of seats will be calculated by the arithmetic progression -
S = n/2 [2a + (n-1)d], where s is the number of seats, n is number of rows, a is the number of seats in first row and d is the number of extra seats added in each row.
d = 29 - 25
Performing subtraction
d = 4
Keep the values in formula -
S = 20/2 [(2×25) + (20 - 1)×4]
Performing multiplication and subtraction
S = 10 [50 + (19×4)]
Performing multiplication
S = 10 [50 + 76]
Performing addition
S = 10 [126]
Performing multiplication
S = 1260
Hence, there are 1260 seats.

Let E, N and T represent the number of exits, the number of spectators and the time taken to exit the stadium respectively
We can write the variation as:
T α N/E
T = kN/E (where k is constant of proportionality)
when N = 25,000, E = 25, T = 20:
T = kN/E
k = TE/N
