The correct formula that defines an arithmetic sequence is option d) tn = 5n + 14.

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms remains constant. In other words, each term can be obtained by adding a fixed value (the common difference) to the previous term.

In option a) tn = 5 + 14, the term does not depend on the value of n and does not exhibit a constant difference between terms. Therefore, it does not represent an arithmetic sequence.

Option b) tn = 5n² + 14 represents a quadratic sequence, where the difference between consecutive terms increases with each term. It does not represent an arithmetic sequence.

Option c) tn = 5n(n+14) represents a sequence with a varying difference, as it depends on the value of n. It does not represent an arithmetic sequence.

Option d) tn = 5n + 14 represents an arithmetic sequence, where each term is obtained by adding a constant value of 5 to the previous term. The common difference between consecutive terms is 5, making it the correct formula for an arithmetic sequence.

The most important thing to notice about a table of q-sort correlates is d. general patterns that emerge.

Q-sorting is a method of ranking items in order of preference or importance, and Q-sort correlates are used to identify relationships between the ranked items. The correlations in the table represent how strongly the items are associated with each other based on their rankings.

While the exact value of the correlations is important for statistical analysis, the most valuable information in a table of q-sort correlates is the general patterns that emerge. These patterns can help to identify groups of items that are closely related to each other, as well as those that are more distantly related.

Understanding the wording of specific items may also be important, as it can impact how the items are ranked and how they relate to each other. However, the primary focus of a table of q-sort correlates is on the relationships between the items, rather than the items themselves.

sec θ = 13/5 and cot θ = 5/12 for the given point on the unit circle.

The given point on the unit circle is (cos θ, sin θ) = (5/13, 12/13).

Using the values provided, we can calculate the other trigonometric ratios:

sec θ = 1/cos θ = 1/(5/13) = 13/5

cot θ = cos θ / sin θ = (5/13) / (12/13) = (5/13) * (13/12) = 5/12

Therefore, sec θ = 13/5 and cot θ = 5/12 for the given point on the unit circle.

The proportion of persons who are 38 years old or older is 0.25.

Proportion is defined as when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal. It is a mathematical comparison between two numbers.

Proportion = (number of persons 38 years old or older) / (total number of persons)

For example, if there are 100 persons and 25 of them are 38 years old or older, the proportion would be:
Proportion = 25 / 100 = 0.25

To round to 2 decimal places, we would round 0.25 to 0.25.

So the proportion of persons who are 38 years old or older is 0.25, or 25%.

Answer:A bar chart is a suitable display to represent data on job classification because it is categorical. Categorical data are data that can be classified into categories, such as job classification. A bar chart is a graphical display that uses bars to represent different categories of data. The bars are plotted horizontally or vertically, and the length of each bar represents the magnitude of the data within the category.

A box plot, on the other hand, is a graphical display used to represent numerical data. It consists of a box (also known as a "box-and-whisker plot") that represents the middle 50% of the data, a line within the box representing the median of the data, and "whiskers" extending from the box to the minimum and maximum data values. Box plots are not suitable for representing categorical data.

Therefore, the correct answer is:

Yes, these data support the scientist's belief that large islands are more effective at protecting at-risk species than small islands. To provide statistical justification, we can compare the probability of extinction for each island size: For large islands, the probability of extinction is 19/208, or approximately 0.091. For small islands, the probability of extinction is 66/299, or approximately 0.221.

The data provided can support the scientist's belief that large islands are more effective than small islands for protecting at-risk species. We can use the concept of probability to calculate the likelihood of extinction for both large and small islands.

For the large island, the probability of extinction for any given species is 19/208 or approximately 0.091. For the small island, the probability of extinction for any given species is 66/299 or approximately 0.221.

Comparing these probabilities, we see that the probability of extinction is higher for at-risk species on small islands than on large islands. This supports the scientist's belief that large islands are more effective for protecting at-risk species.

Additionally, we can use statistical tests such as a chi-square test or a two-sample t-test to confirm whether the difference in extinction rates between large and small islands is statistically significant.

These tests would require more information such as sample size and variance, but based on the provided data alone, the probability calculations suggest that the scientist's belief is supported.

Answer:

x = 2.5

Step-by-step explanation:

In order to solve for x, we need to write an equation. This question gives us the angles of a triangle, so we can use this to write our equation. All angles of a triangle will always add to 180 degrees, therefore:

(12x+6) + 104 + 40 = 180

Now we can just take out the brackets, combine like terms and isolate and solve for x:

12x + 6 + 104 + 40 = 180

12x + 150 = 180

12x + 150 - 150 = 180 - 150

12x = 30

12x/12 = 30/12

x = 2.5

When you divide 6/11 you get 0.5454545454 and so on. It is B and not C because both digits are repeating. Hope this helps! :)

Answer:

B

Step-by-step explanation:

We want to get a denominator made up of all nines, and 11 is a multiple of 99, so we can use it. We can multiply the fraction by \(\frac{9}{9}\) to get a denominator of 99:

\(\frac{6}{11} *\frac{9}{9} = \frac{54}{99}\)

Now, whenever you have a denominator of nines, the amount is how long the repeat pattern is. Also, the numerator would represent the digits that repeat. In this case, it would be two digits long and the digits would be 5 & 4. We can write it as the decimal:

0.54545454.....
