Making marijuana illegal in the United States and alcohol illegal in Saudi Arabia are both examples of how governments can use law to enforce different social norms.

Governments have the power to use legislation as a means to enforce various social norms within their respective societies. Examples of this can be seen in the contrasting policies regarding marijuana in the United States and alcohol in Saudi Arabia.

The illegal status of marijuana in the United States reflects the societal norm that perceives its use as undesirable or harmful while the prohibition of alcohol in Saudi Arabia aligns with the country's cultural and religious values. These demonstrate how governments can utilize laws to shape and uphold different social norms based on their specific contexts and priorities.

The dimensions of the cubes are 10 inches, 8 inches, and 6 inches.

Let's assume the lengths of the edges of the cubes are x, x-2, and x-4, where x is the largest edge length.

The surface area of a cube is given by the formula 6s^2, where s is the edge length.

According to the problem, the total surface area of the three cubes is 900 square inches. Therefore, we can set up the equation:

6x^2 + 6(x-2)^2 + 6(x-4)^2 = 900.

Simplifying the equation:

6x^2 + 6(x^2 - 4x + 4) + 6(x^2 - 8x + 16) = 900.

Expanding and combining like terms:

6x^2 + 6x^2 - 24x + 24 + 6x^2 - 48x + 96 = 900.

18x^2 - 72x + 120 = 900.

Dividing both sides by 6 to simplify:

3x^2 - 12x + 20 = 150.

Rearranging the equation:

3x^2 - 12x - 130 = 0.

Now we can solve this quadratic equation using factoring, completing the square, or the quadratic formula. After solving the equation, we find the solutions:

x = 10 and x = -4/3.

Since the dimensions of the cubes must be positive even integers, we discard the solution x = -4/3.

Within sample variance occurs within a single sample or group.

Within sample variance refers to the variation or dispersion of values within a single sample or group. It measures how much the individual data points deviate from the mean or central tendency within that specific sample. This variance is calculated by taking the average of the squared differences between each data point and the sample mean.

For example, let's say we have a sample of test scores for a group of students. Within sample variance would help us understand how much the individual test scores vary within that particular group. If the test scores are tightly clustered around the mean, the within sample variance would be low, indicating a high level of similarity among the scores. Conversely, if the test scores are widely spread out, the within sample variance would be high, suggesting a greater diversity or variability among the scores.

In summary, within sample variance occurs within a single sample or group and quantifies the dispersion of values around the mean within that sample. It helps assess the level of variation or homogeneity within the data set.

The f-statistic (0.72) is between the critical values (0.214 and 4.025), we fail to reject the null hypothesis.

To determine whether the two production departments differ in terms of unit cost variance, we can perform a hypothesis test. We will use a two-sample F-test, which compares the variances of two independent samples.

The null hypothesis for this test is that the two production departments have equal variances, and the alternative hypothesis is that the variances are not equal. We can write these hypotheses as:

H0: σ1^2 = σ2^2

Ha: σ1^2 ≠ σ2^2

where σ1^2 and σ2^2 are the population variances for the two production departments.

To perform the F-test, we need to calculate the F-statistic:

\(F = s1^2 / s2^2\)

where \(s1^2\) and \(s2^2\) are the sample variances for the two production departments. We can then compare the F-statistic to the critical value from the F-distribution, using the degrees of freedom associated with the two samples.

For this problem, we are not given the sample sizes, so we cannot determine the degrees of freedom directly. However, we can use a conservative estimate for the degrees of freedom, which is the smaller of n1 - 1 and n2 - 1, where n1 and n2 are the sample sizes.

Assuming that the sample sizes are equal and using the conservative estimate for the degrees of freedom, we can calculate the F-statistic as:

F = 42.4 / 58.8 = 0.72

To find the critical value from the F-distribution, we need to choose a significance level (α). Let's use α = 0.05. Using a calculator or a table, we find that the critical values for a two-tailed F-test with degrees of freedom of 9 and a significance level of 0.05 are 0.214 and 4.025.

Since our calculated F-statistic (0.72) is between the critical values (0.214 and 4.025), we fail to reject the null hypothesis. This means that we do not have enough evidence to conclude that the variances of the two production departments are different.

The correct option is B) Not valid. Consider the statement “Since some shoes are sneakers, some non-sneakers are non-shoes.”

We know that all sneakers are shoes, but all shoes are not sneakers.  Hence, some shoes are sneakers. But, this statement does not imply that “some non-sneakers are non-shoes.” This inference cannot be drawn by contraposition. So, it is not valid.Inferences cannot be drawn in contraposition all the time. Contraposition is a type of logical statement that involves reversing and negating the terms of an original proposition. It is a logical relationship between a proposition and its converse.

There are 5,760 ways to arrange the books on the bookshelf.

A permutation is an ordered arrangement of objects, and it can be calculated as follows:

ⁿPₓ = n! / (n - x)!

where n is the total number of objects and r is the number of objects that we are arranging.

To determine the total number of ways in which we can arrange the books on a bookshelf, we need to first calculate the total number of possible arrangements. We can do this by using the fundamental principle of counting, which tells us that the total number of possible arrangements is equal to the product of the number of ways in which each book can be arranged.

Therefore, the total number of possible arrangements can be calculated as follows:

Total number of possible arrangements = Number of ways to arrange math books × Number of ways to arrange history books × Number of ways to arrange science books

In our case, we have 4 math books, 5 history books, and 2 science books, so we can calculate the number of permutations for each type of book as follows:

Number of ways to arrange math books = ⁴P₄ = 4! / (4-4)! = 4! / 0! = 24

Number of ways to arrange history books = ⁵P₅ = 5! / (5-5)! = 5! / 0! = 120

Number of ways to arrange science books = ²P₂ = 2! / (2-2)! = 2! / 0! = 2

Now, we can substitute these values in the formula for the total number of possible arrangements:

Total number of possible arrangements = 24 × 120 × 2 = 5,760

In the double-reciprocal plot equation, the x-axis intercept is -1/Km, and the y-axis intercept is 1/Vmax. Therefore, if you take the reciprocal of the x-axis intercept, you get -Km, and multiplying it by -1 gives you Km.

This method is preferred because it is more accurate than estimating Km based on the position of the curve on the plot or by taking the x-axis intercept where V0 = 1/2 Vmax, which can be influenced by experimental error.

The region enclosed by the curves y = x, y = 3x, and y = -x + 4 needs to be sketched, and its area should be found.

To sketch the region enclosed by the curves, we need to plot the three given curves on a coordinate plane. The first curve is y = x, which represents a straight line passing through the origin (0,0) with a slope of 1. The second curve is y = 3x, which is also a straight line passing through the origin but with a steeper slope of 3. The third curve is y = -x + 4, which represents a line with a y-intercept of 4 and a negative slope of -1. By plotting these three lines on the same coordinate plane, we can see that they intersect at three points: (0,0), (1,3), and (3,1). The region enclosed by these curves is a triangular region with vertices at these three points. To find the area of this triangular region, we can use the formula for the area of a triangle: A = (1/2) * base * height. Let's draw the graph:

     |

   4 |         .  (2, 2)

     |      .

     |   .

     | .

   0 |_____________________

     0     1     2     3     4     5     6

In this graph, the first equation (y = x) is depicted by a diagonal line passing through the origin (0,0). The second equation (y = 3x) is a steeper line, while the third equation (y = -x + 4) is a downward-sloping line with a y-intercept of 4. In this case, the base of the triangle is the distance between the points (0,0) and (3,1), which is 3 units. The height of the triangle is the distance between the point (1,3) and the line y = -x + 4, which is also 3 units. Substituting these values into the area formula, we get A = (1/2) * 3 * 3 = 4.5 square units.
