A square based prism and a triangular prism are the same height. The base of the triangular prism is an equilateral triangle, with an altitude equal in length to the side of the square. Compare the lateral areas of the prisms.

Answers

Answer 1

The lateral area of the square-based prism is larger compared to the lateral area of the triangular prism.

To compare the lateral areas of the square-based prism and the triangular prism, we need to calculate the lateral area of each prism and compare them.

The lateral area of a prism is the sum of the areas of all the lateral faces (excluding the bases). For the square-based prism, there are four rectangular lateral faces, and for the triangular prism, there are three triangular lateral faces.

Let's denote:

s = side length of the square base

h = height of both prisms (which is the same)

For the square-based prism:

The lateral area of each rectangular face is given by s * h (base times height).

Since there are four rectangular faces in total, the total lateral area of the square-based prism is 4 * s * h.

For the triangular prism:

The lateral area of each triangular face is given by (1/2) * s * h (base times height divided by 2, as it's a triangle).

Since there are three triangular faces in total, the total lateral area of the triangular prism is 3 * (1/2) * s * h.

Simplifying these expressions gives us:

Lateral area of the square-based prism = 4 * s * h = 4sh

Lateral area of the triangular prism = 3 * (1/2) * s * h = (3/2)sh

Comparing the two lateral areas, we have:

Lateral area of the square-based prism : Lateral area of the triangular prism

4sh : (3/2)sh

We can see that the lateral area of the square-based prism is greater than the lateral area of the triangular prism.

In summary, the lateral area of the square-based prism is larger compared to the lateral area of the triangular prism.

Determine the convergence or divergence of the sequence with the given nth term. if the sequence converges, find its limit. (if the quantity diverges, enter diverges. ) an = 5 n 5 n 8

Answers

The limit of the sequence as n approaches infinity is 1. Since the sequence converges to a specific value (1).

To determine the convergence or divergence of the sequence with the given nth term, let's examine the expression:

an = 5n / (5n + 8)

As n approaches infinity, we can analyze the behavior of the sequence.

First, let's simplify the expression by dividing both the numerator and denominator by n:

an = (5n/n) / [(5n + 8)/n]

= 5 / (5 + 8/n)

As n approaches infinity, the term 8/n approaches zero since n is increasing without bound. Therefore, we have:

an ≈ 5/5

an ≈ 1

Hence, the limit of the sequence as n approaches infinity is 1.

Since the sequence converges to a specific value (1), we can conclude that the sequence converges.

could the result from part (a) be the actual number of survey subjects who said that their companies conduct criminal background checks on all job applicants? why or why not?

Answers

No, the result from part (a) cannot be the actual number of survey subjects who said that their companies conduct criminal background checks on all job applicants.

The result from part (a) cannot be considered the actual number of survey subjects who said that their companies conduct criminal background checks on all job applicants for several reasons. Firstly, the result is obtained from a sample of 50 employees, which may not accurately represent the entire population of job applicants and companies.

A larger sample size would be necessary to ensure a more reliable estimate. Additionally, survey responses can be subject to biases, such as response bias or social desirability bias, which can impact the accuracy of the reported information. Participants may not provide honest answers or may misunderstand the question, leading to inaccuracies in the data. Therefore, to determine the actual number of survey subjects who said their companies conduct criminal background checks on all job applicants, a more comprehensive and rigorous study involving a larger and more diverse sample would be needed.

most pregnancies are full term, but some are preterm (less than 37 weeks). of those that are preterm, they are classified as early (less than 34 weeks) and late (34 to 36 weeks). a report examined those outcomes for one year, broken down by age of the mother. is there evidence that the outcomes are not independent of age group?

Answers

To determine if there is evidence that the outcomes are not independent of age group, we can use statistical analysis. First, we need to define the null and alternative hypotheses.

In this case, the null hypothesis would be that the outcomes are independent of age group, while the alternative hypothesis would be that the outcomes are dependent on age group. Next, we can conduct a chi-squared test of independence to analyze the data. This test compares the observed frequencies of the outcomes across different age groups to the expected frequencies if the outcomes were independent of age group. If the calculated chi-squared value is greater than the critical value, we can reject the null hypothesis and conclude that there is evidence that the outcomes are not independent of age group. On the other hand, if the calculated chi-squared value is less than or equal to the critical value, we fail to reject the null hypothesis and conclude that there is not enough evidence to suggest a relationship between the outcomes and age group.

In conclusion, by conducting a chi-squared test of independence, we can determine if there is evidence that the outcomes are not independent of age group.
