There are 4845 different ways to select 16 questions out of a total of 20 questions on the exam.

To determine the number of different ways you can select 16 questions out of a total of 20 questions, we can use the concept of combinations.

In this case, we want to select 16 questions from a set of 20 questions, and the order in which we select them doesn't matter. This scenario can be represented by the combination formula.

The formula for combinations is given by:

C(n, k) = n! / (k!(n-k)!)

Where:

n is the total number of items in the set (20 questions)

k is the number of items to be selected (16 questions)

! denotes the factorial operation

Using the combination formula, we can calculate the number of different ways to select the questions:

C(20, 16) = 20! / (16!(20-16)!)

= 20! / (16!4!)

= (20 * 19 * 18 * 17) / (4 * 3 * 2 * 1)

= 4845

If person c must always sit on the right of person a, then there are two possible seating arrangements for them: either a is at the top of the table and c is to their right, or c is at the top of the table and a is to their left.

In either case, we can consider person c as fixed in place and count the number of ways to seat the remaining three people around the table.
If we seat person a first, there are four choices for their seat. Then person b can be seated in any of the remaining three seats. Finally, person d can be seated in one of the two remaining seats. So, there are 4 x 3 x 2 = 24 ways to seat the remaining three people around the table. Therefore, there are 2 x 24 = 48 different seatings possible overall.
To draw the possibilities, we can start by drawing a circle to represent the circular table. Then, we can label the top of the circle as either person a or person c (depending on which one we choose to fix in place). From there, we can draw arrows to represent the possible positions for person b and person d, making sure to avoid any duplicates due to rotations of the table. By doing this, we can visualize all 48 possible seatings for the four people around the circular table.

The value of k must be c) 3, as it satisfies the requirement for the side length of the paving stone in feet, resulting in a meaningful relationship between the area of the patio and the number of paving stones.

To find the value of k, we need to consider the relationship between the area y of the patio and the number of paving stones x used to make the patio.

Since the top surface of each paving stone is a square with side length k feet, the area of each paving stone is [tex]k^2[/tex] square feet.

Now, let's consider the relationship between the area of the patio and the number of paving stones. We know that there will be no gaps between the paving stones, and they will not overlap. This implies that the area of the patio will be equal to the sum of the areas of all the paving stones used.

Let's assume that each paving stone covers an equal area of the patio. In this case, the area y of the patio will be directly proportional to the number of paving stones x used, and the constant of proportionality is the area of each paving stone, which is [tex]k^2[/tex].

Therefore, the relationship between y and x can be expressed as [tex]y = k^2x.[/tex]

From this relationship, we can see that the value of k will depend on the relationship between the units used for area (square feet) and the number of paving stones (unitless).

Since we want the side length k to be in feet, the value of k can be determined by considering the options provided: a) 1, b) 2, c) 3, d) 4.

We can eliminate options a) 1, b) 2, and d) 4 since these values would not result in a meaningful relationship between the area of the patio and the number of paving stones.

Therefore, the value of k must be c) 3, as it satisfies the requirement for the side length of the paving stone in feet, resulting in a meaningful relationship between the area of the patio and the number of paving stones.

The expression that best models the population of the herd is:

y = (34/5)x - 558, where y is the population of the herd, and x is the time in years since 2010.

To model the population of the bison herd as a linear function of time, we can use the slope-intercept form of a linear equation, which is y = mx + b, where y is the population of the herd, x is the time in years since 2010, m is the slope of the line, and b is the y-intercept of the line.

To find the slope of the line, we can use the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) is the point (2010, 122), and (x2, y2) is the point (2015, 156).

m = (156 - 122) / (2015 - 2010) = 34 / 5

So the slope of the line is 34/5.

To find the y-intercept of the line, we can use the point-slope form of a linear equation:

y - y1 = m(x - x1)

where (x1, y1) is the point (2010, 122), and m is the slope we just found.

y - 122 = (34/5)(x - 2010)

y - 122 = (34/5)x - 13668

Let's assume the height of the rectangle is h cm. According to the problem, the base is 1 cm more than the height, so the base would be (h + 1) cm. The formula for the area of a rectangle is given by A = length × width.

Given that the area is 100 cm², we can write the equation as follows:

100 = h × (h + 1)

To solve this equation using a trial and improvement method, we can start by assuming a value for h and check if it satisfies the equation. Let's try h = 9:

100 = 9 × (9 + 1)

100 = 9 × 10

100 = 90

Since 90 is not equal to 100, we can try a different value. Let's try h = 10:

100 = 10 × (10 + 1)

100 = 10 × 11

100 = 110

Again, 110 is not equal to 100. We can continue this process until we find a value of h that satisfies the equation. Let's try h = 9.5:

100 = 9.5 × (9.5 + 1)

100 = 9.5 × 10.5

100 = 99.75

Now, 99.75 is close to 100 but not exactly. Let's try h = 9.6:

100 = 9.6 × (9.6 + 1)

100 = 9.6 × 10.6

100 = 101.76

101.76 is greater than 100, so we can conclude that the value of h is closer to 9.5 than 9.6. Therefore, the value of h, correct to 1 decimal place, is approximately 9.5 cm.

A sample size of at least 241 U.S. residents would be required to reduce the standard deviation of the sampling distribution to one-half its original value, assuming that the true proportion of U.S.

The standard deviation of a sample proportion is given by the formula:

σ = √p(1-p)/n

An appraisal that is based on facts and is likely to be numerical is a quantitative appraisal. Quantitative appraisals involve the use of data and statistics to determine the value of a property or asset.

This type of appraisal is commonly used in the real estate industry to determine the market value of a property by comparing it to similar properties in the area. Quantitative appraisals typically involve the use of various methods such as the cost approach, sales comparison approach, and income approach to determine the value of a property. These methods rely on quantitative data such as the property's size, location, condition, and income potential. In contrast, a qualitative appraisal is based on subjective criteria such as the overall condition and aesthetic appeal of a property. Overall, quantitative appraisals are considered to be more objective and reliable since they are based on measurable and verifiable data.

An appraisal that is based on facts and is likely to be numerical is an objective appraisal.

An objective appraisal is a type of evaluation that relies on factual information, data, and measurable criteria. In contrast to subjective appraisals, which are based on personal opinions, feelings, and preferences, objective appraisals aim to minimize bias and ensure a fair and accurate assessment.

Objective appraisals can be used in various settings, including performance evaluations in the workplace, academic assessments, and property valuations. In each case, the focus is on using quantifiable measures and clear, predetermined criteria to make an evaluation.

For instance, in a work performance evaluation, an objective appraisal might consider metrics such as sales figures, customer satisfaction ratings, or project completion rates. These numerical values can provide a clearer picture of an employee's performance, compared to subjective assessments, which may be influenced by personal relationships or other factors unrelated to actual performance.

Similarly, in an academic setting, objective appraisals can include standardized test scores, number of assignments completed, or attendance records. This data-driven approach helps to create a more equitable assessment of a student's abilities and achievements.

In summary, an objective appraisal is an evaluation method that relies on factual information and numerical data to minimize bias and provide an accurate and fair assessment.

The dimensions of the garden that minimize the cost are approximately 2.5 feet by 64.8 feet.

To find the dimensions of the garden that minimize the cost, we can use optimization techniques. Let's denote the length of the garden as L and the width as W.

The cost of the brick wall is $60 per foot, and since only one side is enclosed by the brick wall, the cost for that side is 60L. The cost of the metal fence is $40 per foot, and since three sides are enclosed by the metal fence, the cost for those sides is 40(2L + W).

The total cost C is the sum of the costs for the brick wall and the metal fence:

C = 60L + 40(2L + W)

Given that the area of the garden is 162 square feet, we have L * W = 162.

To minimize the cost, we can take the derivative of the cost function with respect to L and set it equal to zero:

dC/dL = 60 + 80 = 0

Solving for L, we find L = 2.5 feet.

Substituting L = 2.5 into the area equation, we get W = 162 / 2.5 = 64.8 feet.

Z = (p - p₀) / √(p₀(1 - p₀) / n),

where p₀ represents the proportion specified under the null hypothesis, which is 0.65 in this case.

Substituting the values into the formula, we have:

Z = (0.34 - 0.65) / √(0.65(1 - 0.65) / 200) ≈ -9.91.

Looking up the z-value in a standard normal distribution table or using statistical software, we find that the critical value for a one-sided 99 percent confidence level is approximately 2.33.

Since the test statistic (Z = -9.91) is much smaller (in absolute value) than the critical value (2.33), we have strong evidence to reject the null hypothesis. This means that the proportion of constituents in favor of legalization is significantly less than 65 percent.

0.4 hours it take to fill a pool if 1 cubic foot is about 7.5 gallon

The radius of the cylinder is half of the diameter, so r = 8/2 = 4 feet.

The volume of the cylinder is given by:

V = π(4²)(1.5)

V = 24π cubic feet

We know that 1 cubic foot is about 7.5 gallons, so the pool has a capacity of:

24π x 7.5 = 180.96 gallons

At a filling rate of 8 gallons per minute, the time it takes to fill the pool can be found by dividing the pool's capacity by the filling rate:
