Chose the list that shows the numbers in order from smallest to largest 0.39 ,0.85, 0.731, 0.773
The numbers in order from smallest to largest are:
0.39, 0.731, 0.773, 0.85
To arrange the numbers in order from smallest to largest, i.e. in ascending order, we compare them digit by digit starting from the left.
Comparing the first digit, we have 0.39, 0.731, 0.773, and 0.85. Since 0.39 is the smallest among the first digits, it comes first in the order.
Next, we compare the second digit of each number. We have 0.39, 0.731, 0.773, and 0.85. Among the second digits, 0.731 has the smallest value, so it comes next in the order.
Moving on to the third digit, we have 0.39, 0.731, 0.773, and 0.85. The third digit in all the numbers is different, so we compare them. The smallest third digit is in 0.39, so it comes before the other numbers.
Finally, we compare the fourth digit, but only the number 0.773 has a fourth digit. Since it is the only number with a fourth digit, it comes last in the order.
Putting it all together, the numbers in order from smallest to largest are: 0.39, 0.731, 0.773, and 0.85.

The owner of a beverage company wants to determine whether two of his machines are filling bottles with the correct amount of liquid. He randomly selects 20 bottles filled by each of the two machines and measures the number of ounces that the bottles contain. The histograms below show the data. If the machines are designed to dispense between 5 and 6 ounces into a bottle, which machine appears to be doing a better job? Explain how you determined your answer.
Based on the histograms, it appears that Machine B is doing a better job of dispensing the correct amount of liquid.
What is histogram?The most common graph for displaying frequency distributions is a histogram.
To begin, Machine B's histogram is more symmetrically distributed around the 5.5-ounce mark, which is the target fill level.
Machine A's histogram, on the other hand, is skewed to the right, indicating that it is more likely to dispense more than 5.5 ounces.
Second, Machine B's histogram has a narrower spread, with most measurements falling between 5.4 and 5.6 ounces.
This indicates that the machine fills the bottles consistently within a narrow range of the target fill level.
Thus, the histogram for Machine A, on the other hand, has a wider range, with some measurements falling below 5.4 ounces and others exceeding 5.6 ounces, indicating a less consistent performance.

In a 4-week study about the effectiveness of using magnetic

wore magnetic insoles and 41 randomly chosen subjects wore
nonmagnetic soles. When asked if they felt better, 17 of the
magnetic sole wearers said yes, and 18 of the nonmagnetic sole
wearers said yes also. Construct and interpret a 95% confidence

[Select)
captures the true difference of the
proportions. There is
convincing evidence of a
significant difference in the proportions.
р
The 95% confidence interval for the difference in proportions of subjects who felt better after wearing magnetic or nonmagnetic insoles is calculated to determine if there is a significant difference. The confidence interval provides an estimate of the range in which the true difference in proportions lies. If the interval does not include zero, it suggests a significant difference.
To construct the confidence interval, we need to calculate the standard error and use it to determine the margin of error. The formula for the standard error of the difference in proportions is:
SE = sqrt[(p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2)]
where p1 and p2 are the proportions of subjects who felt better in the magnetic and nonmagnetic groups, and n1 and n2 are the sample sizes of the respective groups.
Using the given information, we have:
p1 = 17/54 = 0.315
p2 = 18/41 = 0.439
n1 = 54
n2 = 41
Plugging these values into the formula, we can calculate the standard error. Then, we can determine the margin of error by multiplying the standard error by the critical value associated with a 95% confidence level (assuming a normal distribution).
Once we have the margin of error, we can construct the confidence interval by subtracting and adding the margin of error from the difference in proportions (p1 - p2). The resulting interval represents the range in which we are 95% confident the true difference lies.
The interpretation of the confidence interval is as follows: if the interval contains zero, it suggests that there may not be a significant difference between the proportions. On the other hand, if the interval does not include zero, it provides evidence of a significant difference.

(Do not round your intermediate calculations. Round your final answer to 4 decimal places.) b. Each system component has a backup with a probability of .85 and a switch that is 100 percent reliable. (Do not round your intermediate calculations. Round your final answer to 4 decimal places. c. Each system component has a backup with a probability of .85 and a switch that is 90 percent reliable. (Do not round your intermediate calculations. Round your final answer to 4 decimal places.)
a. The probability that the system will operate as shown is approximately 0.6141.
b. Probability ≈ 0.6141The probability remains the same as in the previous case, which is approximately 0.6141.
c. The probability that the system will operate with each component having a backup with a probability of 0.85 and a switch that is 90% reliable is approximately 0.6485.
a. To find the probability that the system will operate as shown, we multiply the probabilities of each component. Since the system is shown to have three components with a probability of 0.85 each, we can calculate:
Probability = 0.85 × 0.85 × 0.85
Probability ≈ 0.6141
The probability that the system will operate as shown is approximately 0.6141.
b. In this case, each system component has a backup with a probability of 0.85 and a switch that is 100% reliable. Since the backup has a probability of 0.85, and the switch is 100% reliable (probability = 1), we can calculate the probability as:
Probability = 0.85 × 0.85 × 0.85
Probability ≈ 0.6141The probability remains the same as in the previous case, which is approximately 0.6141.
c. In this scenario, each system component has a backup with a probability of 0.85, but the switch is 90% reliable (probability = 0.90). We can calculate the probability as:
Probability = 0.85 × 0.90 × 0.85
Probability ≈ 0.6485
The probability that the system will operate with each component having a backup with a probability of 0.85 and a switch that is 90% reliable is approximately 0.6485.

To balance the line by choosing the assignable task with the longest task time first, you need to follow these steps. Determine the task times for each assignable task in the line.
Identify the assignable task with the longest task time. Assign that task to the first station in the line. Calculate the remaining cycle time by subtracting the task time of the assigned task from the total cycle time.
Repeat steps 2-4 for the remaining assignable tasks, considering the updated cycle time after each assignment.
Task A has the longest task time, so it is assigned to the first station. After each assignment, the cycle time is updated by subtracting the task time of the assigned task. Task B is assigned to the second station, and Task C is assigned to the third station. Since Task C has a task time of 1.2 minutes, the remaining cycle time becomes 0. After that, Task D and Task E are not assigned any task time because the remaining cycle time is already 0. The specific values will depend on the actual task times and cycle time in your scenario.

9. Jackie is an airline mechanic. Her company pays \( 40 \% \) of the \( \$ 3,900 \) annual cost of group health insurance. How much does she pay for it monthly? (4 points)
Jackie pays $130 monthly for her group health insurance.
To find out how much Jackie pays for her group health insurance monthly, we need to calculate 40% of the annual cost. Given that the annual cost is $3,900 and her company pays 40% of that, we can calculate the amount Jackie pays.
First, we find the company's contribution by multiplying the annual cost by 40%: $3,900 × 0.40 = $1,560. This is the amount the company pays towards Jackie's health insurance.
To determine Jackie's monthly payment, we divide her annual payment by 12 (months in a year) since she pays monthly. So, Jackie's monthly payment is $1,560 ÷ 12 = $130.
Therefore, Jackie pays $130 per month for her group health insurance. This calculation takes into account the company's contribution of 40% of the annual cost, resulting in an affordable monthly payment for Jackie.

Suppose that a certain examination is to be taken by five students independently of one another, and the number of minutes required by any particular student to complete the examination has the exponential distribution for which the mean is 80. Suppose that the examination begins at 9:00 a.m.
Required:
Determine the probability that at least one of the students will complete the examination before 9:40 a.m.
If a certain examination is to be taken by five students independently of one another, and the number of minutes required by any particular student to complete the examination has the exponential distribution for which the mean is 80 and the examination begins at 9:00 a.m, then the probability that at least one of the students will complete the examination before 9:40 a.m is 80.6%.
To find the probability that at least one of the students will complete the examination before 9:40 a.m, follow these steps:
The probability that at least one of the five students will complete the examination before 9:40 a.m can be calculated by taking the complementary of the probability that none of the students complete the examination before 9:40 a.mLet X be the number of minutes it takes a student to complete the examination. Since X follows an exponential distribution with a mean of 80 minutes, the probability density function (PDF) of X is given by: f(x) = (1/80) * exp(-x/80). So, λ=1/80The probability that a single student will complete the examination before 9:40 a.m: P(X ≤ 40) = ∫₀⁴⁰ λe^(-λx) dx = [-e^(-λx)]₀⁴⁰= 1 - e^(-λ * 40)= 1 - e^(-1/2)= 0.3935Therefore, the probability that all five students complete the examination after 9:40 a.m. =P(X > 40)^5=(1-P(X≤40))⁵ = (1 - 0.3935)⁵= 0.1940 (rounded to 4 decimal places)P(at least one student completes before 9:40) = 1 - P(all five students complete after 9:40)= 1 - 0.1940= 0.8060 or 80.6%.Therefore, the probability that at least one of the five students will complete the examination before 9:40 a.m is 0.8060 or 80.6%.

In programming, you can use relational operators (e.g., <, >, ==, !=) and math operators (e.g., +, -, *, /) together in the same expression. This is often used in conditional statements or loops to compare calculated values.
For example, consider the following expression:
`if (2 * 3) > (4 + 1)`
In this expression, we have math operators (*) and (+) and a relational operator (>). The math operations are evaluated first, resulting in:
`if (6) > (5)`
Then, the relational operator (>) is evaluated, and the expression becomes:
`if True`
The expression is true because 6 is greater than 5.
