The height of the Sears Tower's building is approximately 725 feet.

Let's denote the height of the building as h, and the height of the antenna as a. According to the information given, the total height of the tower (t) is the sum of the heights of the building and the antenna, so we have t = h + a.

We are also given that the difference in heights between the building and the antenna is 279 feet, meaning a = h + 279.

Substituting this value of a into the equation for t, we have t = h + (h + 279). Simplifying, we get t = 2h + 279.

Since the total height of the tower, t, is given as 1729 feet, we can now solve the equation 1729 = 2h + 279 for h.

Rearranging the equation, we have 2h = 1729 - 279, which simplifies to 2h = 1450. Dividing both sides by 2, we find h = 1450/2 = 725.

Therefore, the height of the Sears Tower's building is approximately 725 feet.

Answer:

The lake is 11.3 m below sea level.

Step-by-step explanation:

Mei's initial position on the field was 0.5 m below sea level.

The lantern rises 913.9 m after its release.

The lantern descends 925.2 m to land on the surface of a lake.

Let the elevation of the lake to sea level be represented by x.

So that;

x = 913.9 - 925.2

  = -11.3

x = 11.3 m below sea level.

Therefore, the lake is 11.3 m below sea level.

The evolution of the function call (things '(11 -2 31)) is as follows:

(things '(11 -2 31)) -> (things '(-2 31)) -> (things '(31)) -> (things '()) -> '() the final result of the given call is '().

The given function is a recursive function called "things" that takes a list as input. It checks if the list is empty (null), and if so, it returns an empty list. Otherwise, it checks if the first element of the list (car x) is greater than 10. If it is, it adds 1 to the first element and recursively calls the "things" function on the rest of the list (cdr x). If the first element is not greater than 10, it subtracts 1 from the first element and recursively calls the "things" function on the rest of the list. The function then returns the result.

Now, let's see the evolution resulting from the call (things '(11 -2 31)):

1. (things '(11 -2 31))

  Since the list is not empty, we move to the next if statement.

  The first element (car x) is 11, which is greater than 10, so we add 1 to it and recursively call the "things" function on the rest of the list.

  The recursive call is (things '(-2 31)).

2. (things '(-2 31))

  Again, the list is not empty.

  The first element (car x) is -2, which is not greater than 10, so we subtract 1 from it and recursively call the "things" function on the rest of the list.

  The recursive call is (things '(31)).

3. (things '(31))

  The list is still not empty.

  The first element (car x) is 31, which is greater than 10, so we add 1 to it and recursively call the "things" function on the rest of the list.

  The recursive call is (things '()).

4. (things '())

  The list is now empty, so the function returns an empty list.

Answer:

the angle which is equal to its supplement is 90 degree

a. The sample sizes must be equal: False. While equal sample sizes can improve the statistical power of the test, they are not necessary for the confidence interval to be valid.

b. The population standard deviations must be unequal: False. Welch's two-sample t-confidence interval can handle unequal population standard deviations, but it is not a requirement.

c. The distribution of weight loss of the two treatments are approximately normally distributed: True. For the confidence interval to be valid, the weight loss distributions should be approximately normal. This is a key assumption in t-tests.

d. The volunteers in the supplement group are paired with volunteers in the placebo group: False. This would be a requirement for a paired t-test, not a Welch's two-sample t-test. The volunteers are randomly assigned, so there is no pairing.

e. The expected number of people who lose weight in each group is at least 5: False. This condition relates to the expected frequencies in a chi-square test, not a Welch's two-sample t-test. The validity of the confidence interval does not depend on this condition.

Answer:

(1, 6.71)

Step-by-step explanation:

I'm assuming that you need to solve this by substitution or elimination since you didn't include any context in your question, just the equations.

To solve this by elimination, first, decide on a variable you want to get rid of / cancel out. I chose y. To do this, you need to find the least common multiple (LCM) of 7 and 5, which is 35. Now, multiply the top equation, 21x + 7y = 42, by -5. Multiply the bottom equation, -5x + 5y = 10, by 7. Make sure when you multiply that you either make the 5 or the 7 negative so you can cancel out y. I chose to make 5 negative.

After you multiply by the -5 and the 7, rewrite your new equations:

-105x - 35y = -210

-35x + 35y = 70

Now, add the two equations together. When you do this, the y's cancel out and you're left with -140x = -140. Now, divide both sides by -140, and you're left with x = 1. Plug the value of x into one of your original equations. I chose the bottom equation, -5x + 5y = 10.

-5(1) + 7y = 42   ----->   -5 + 7y = 42.

Add -5 to both sides, which gives you 7y = 47. Divide both sides by 7, which gives you y = 6.71.

The last step is to put the values of x and y into a point: (1, 6.71).

To determine the number of sheets of cardboard in a stack, we need to use the information given in the problem.

We know that each sheet of cardboard is 1 inch thick, and 16 sheets are stacked on top of each other in packages. The height of each stack is 21 inches.

Using the model of a ruler, we can divide the height of the stack (21 inches) by the thickness of each sheet (1 inch) to find the number of sheets in the stack.

21 ÷ 1 = 21

So, there are 21 sheets of cardboard in a stack.

To write an expression that can be used to determine the number of sheets of cardboard in a stack, we can use:

Number of sheets = height of stack ÷ thickness of each sheet

Or, substituting the given values: Number of sheets = 21 ÷ 1 = 21

This expression is simply a representation of the model we used earlier. It shows that we can determine the number of sheets in a stack by dividing the height of the stack by the thickness of each sheet. In this case, the expression yields the same result as the model, which is 21 sheets.

The average value of f on the closed interval 2 < < < 6 is  0.722. The correct answer is C.

The average value of a function f on the interval [a, b] is given by:

average value = (1 / (b-a)) * ∫(a to b) f(x) dx

Using this formula, we get:

average value of f on [2, 6] = (1 / (6 - 2)) * ∫(2 to 6) f(x) dx

We now need to evaluate the integral ∫(2 to 6) f(x) dx. Using integration by parts, we can simplify this integral as follows:

∫(2 to 6) f(x) dx = [x(x2+7)sin(5x) + 2(x2+2)cos(5x)] from x=2 to x=6

= [6(100sin30 - 4cos30) + 20cos30 - 2(20sin30 - 8cos30)]/4

= (75√(3) + 25)/2

= 37.5√(3) + 12.5

Therefore, the average value of f on [2, 6] is:

average value = (1 / (6 - 2)) * ∫(2 to 6) f(x) dx

= (1/4) * (37.5√(3) + 12.5)

= 9.375√(3) + 3.125

=  0.722

So the answer is (C) 0.722 (rounded to three decimal places).

The Length of the conjugate axis is equal to 2b. The transverse axis is an essential feature of a hyperbola, as it determines the overall shape of the hyperbola.

In a hyperbola, the name of the green segment is called the transverse axis. The transverse axis is the longest distance between any two points on the hyperbola, and it passes through the center of the hyperbola. It divides the hyperbola into two separate parts called branches.

The transverse axis of a hyperbola lies along the major axis, which is perpendicular to the minor axis. Therefore, it is also sometimes called the major axis.

The other axis of a hyperbola is called the conjugate axis or minor axis. It is perpendicular to the transverse axis and passes through the center of the hyperbola. The length of the conjugate axis is usually shorter than the transverse axis.In the hyperbola above, the green segment is the transverse axis, and it is represented by the letters "2a". Therefore, the length of the transverse axis is equal to 2a.

The blue segment is the conjugate axis, and it is represented by the letters "2b".

Therefore, the length of the conjugate axis is equal to 2b.The transverse axis is an essential feature of a hyperbola, as it determines the overall shape of the hyperbola. In particular, the distance between the two branches of the hyperbola is determined by the length of the transverse axis.

If the transverse axis is longer, then the branches of the hyperbola will be further apart, and the hyperbola will look more stretched out. Conversely, if the transverse axis is shorter, then the branches of the hyperbola will be closer together, and the hyperbola will look more compressed.

Every stage of the HRM process plays a critical role in achieving the organization's goals, and HRM managers must ensure that every stage is executed correctly.

Human Resource Management (HRM) is the process of selecting, hiring, training, developing, compensating, and evaluating employees in an organization. HRM is the backbone of an organization, as it is responsible for finding and keeping talented workers. The HRM process is an essential function for the success of an organization. Below are the stages in the HRM process:

Stage 1: Planning HRM process: The HRM process begins with the planning stage. In this stage, an organization decides how many workers they require, the kind of jobs to be filled, and the skills necessary for the job. The HRM process needs to analyze and predict future workforce needs to ensure there is a balanced workforce.

Stage 2: Recruiting: After the organization has developed a staffing plan, the next stage is to start recruiting and selecting candidates for the jobs. HRM managers should be able to attract the right candidates by promoting job postings, reviewing resumes, and conducting job interviews. The objective is to find the best person for the job.

Stage 3: Hiring: Once the recruitment process is over, HRM managers proceed to hire the best candidates. The hiring process must be done in a timely and efficient manner.

Stage 4: Developing and Training: Once hired, employees need to be trained and developed to perform their duties successfully. Employee development and training programs can help employees improve their knowledge and skills. It is essential to create a training program that aligns with the organization's goals.

Stage 5: Performance Appraisal: HRM managers must ensure that employees are performing well and meeting their targets. Regular performance appraisals help in identifying the areas that need improvement.

Stage 6: Compensation: HRM is responsible for determining the appropriate compensation packages for employees. The HRM process needs to provide equitable and fair compensation for employees.

When any part of the HRM process is neglected, it can lead to the organization's failure. For instance, if HRM managers fail to develop a staffing plan, the organization may not have the required workforce, leading to poor productivity. Similarly, if the recruitment process is not done correctly, it may lead to the hiring of the wrong employees. If there is no employee training program, employees may not have the necessary skills to perform their duties, leading to poor performance and decreased productivity.

When the HRM process works well, it can lead to increased productivity, employee satisfaction, and lower employee turnover. HRM managers can attract and retain talented employees, resulting in the organization's growth and success. A well-planned HRM process can align with the organization's goals, mission, and values, ensuring that employees are working towards the same objectives. In conclusion, the HRM process is essential to the success of an organization. Every stage of the HRM process plays a critical role in achieving the organization's goals, and HRM managers must ensure that every stage is executed correctly.

Answer:

Step-by-step explanation:

The critical t-value is approximately 1.753.

To find the critical value for a 96% confidence interval with a sample size of 15, we need to determine the t-value from the t-distribution table. The t-distribution table is a statistical tool used to determine the probability of a t-value given the degrees of freedom (df) and the desired level of significance (α).

In this case, we have a sample size of 15, which means our degrees of freedom are 14 (n - 1). Looking at a t-distribution table for 14 degrees of freedom and a 96% confidence interval.

This means that if we were to construct a confidence interval from a sample size of 15, the margin of error would be calculated by multiplying the critical t-value of 1.753 by the standard deviation of the sample and dividing by the square root of the sample size. The resulting interval would contain the population mean with 96% confidence.

It's essential to note that the critical value will change as the sample size and confidence level change. Therefore, it's crucial to use the correct table to find the corresponding critical values for a given dataset's sample size and confidence level.
