Answer:

\(t^* = 1.740\)

Explanation:

Given

\(n = 18\) --- sample

\(CI= 90\%\) --- confidence interval

Required

Determine the critical value

Start by calculating the degrees of freedom (df)

\(df = n - 1\)

\(df = 18 - 1\)

\(df = 17\)

Next, calculate the significance level

\(\alpha = \frac{1 - CI}{2}\)

This gives:

\(\alpha = \frac{1 - 90\%}{2}\)

Express percentage as decimal

\(\alpha = \frac{1 - 0.90}{2}\)

\(\alpha = \frac{0.10}{2}\)

\(\alpha = 0.05\)

Next, we look at the t table at

\(df = 17\)

and

\(\alpha = 0.05\)

We have the critical value to be:

\(t^* = 1.740\)

The 90 percent confidence interval for the population mean (μ) is (33.423, 38.577).

Confidence Interval = X ± Z * (s/√n)

Where:

s is the sample standard deviation.

Given:

X = 36

s = 7

n = 20

For a 90 percent confidence level, the Z-score is 1.645 (corresponding to the 0.05/2 critical values from the standard normal distribution table).

Plugging in the values:

Confidence Interval = 36 ± 1.645 * (7/√20)

Confidence Interval = 36 ± 1.645 * (7/√20)

= 36 ± 1.645 * (7/4.472)

= 36 ± 1.645 * 1.567

= 36 ± 2.577

Therefore, the 90 percent confidence interval for the population mean (μ) is (33.423, 38.577).

Without understanding the exact content, context or scope of the dictionary that you're talking about, it is challenging to determine the exact position of the word "buccaneer." However, using simple logic, as per the alphabetical order, the word "buccaneer" can likely be positioned between the words based on the order of their starting alphabets.

For example, if the words "bubble" and "bucket" are already present in that particular dictionary, the word "buccaneer" can be placed between them, and it would follow "bubble" and precede "bucket".

The precise positioning of "buccaneer" would rely on the words that are already there in the dictionary and the sorting rules used by the publisher which can include (and not be limited to)- the consideration of spaces, special characters, capitalization, etc.

w(t)=5.5 t+79.5 is the equation for the relationship between weight and the number of months.

A mathematical function from a set X to a set Y assigns exactly the same number of elements from Y to each element of X.

The sets X and Y collectively constitute the domain and codomain of the function.

a mathematical expression, rule, or law that establishes the relationship between two variables, one of which is independent, and the other of which is dependent.

Mathematics is filled with functions, which are crucial for creating physical connections in the sciences.

If, y = MX + b

Then m, the slope, is 5.5.

We need to find b.

When x=11, y=140, so: (140)=(5.5)(11)+b.

140=60.5+b

b=79.5

The values for x, y, and m are plugged in.

After simplifying, we take 60.5 off both sides.

This makes the equation:

y=5.5 x+79.5

Or, in the context of this equation:

w(t)=5.5 t+79.5

Therefore, w(t)=5.5 t+79.5 is the equation for the relationship between weight and the number of months.

OPTION B

Explanation:

The total cost for borrowing a book for c days, where c is greater than 10, can be calculated as follows:

For the first 5 days, the cost is a cents per day. So the cost for the first 5 days is 5a cents.

For the remaining days (c - 5), the cost is b cents per day. So the cost for the remaining days is b(c - 5) cents.

Therefore, the total cost for borrowing a book for c days is the sum of the cost for the first 5 days and the cost for the remaining days:

Total cost = 5a + b(c - 5) = 5a + bc - 5b

Option B, a + b(c - 5), is the correct answer.

The total cost for borrowing a book for c days is a + b(c - 5).The correct answer is option B.

To calculate the total cost for borrowing a book for c days, where c is greater than 10, we need to consider two scenarios: the first 5 days and the remaining days after that.

For the first 5 days, the library charges a cents per day. So, the cost for the first 5 days is 5a.

For the remaining days (c - 5), the library charges b cents per day. So, the cost for the remaining days is (c - 5) * b.

To find the total cost, we sum up the costs for the first 5 days and the remaining days:

Total cost = 5a + (c - 5) * b.

Simplifying this expression, we get:

Total cost = 5a + bc - 5b.

Rearranging the terms, we can write it as:

Total cost = a + bc - 5b.

Therefore, the correct option is B. a + b(c - 5).

Answer:

The test subjects are first broken into groups based on a certain variable of interest before being assigned to each treatment condition.

Keeping knowledge learned in a particular curriculum separate from knowledge learned in other curricula can have several consequences. When students compartmentalize their knowledge, they may struggle to see the connections and relationships between different subjects or disciplines. This can lead to a fragmented understanding of the topics and hinder their ability to apply knowledge in real-world situations. By keeping knowledge separate, students may struggle to transfer what they have learned in one context to another. They may not recognize the relevance or applicability of their knowledge in different situations, limiting their ability to think critically and solve problems across disciplines. When students focus solely on the knowledge within a specific curriculum, they may develop a narrow perspective and miss out on interdisciplinary insights. Many real-world problems require a multidisciplinary approach, and by keeping knowledge separate, students may miss out on opportunities for innovation and creative problem-solving. By compartmentalizing knowledge, students may limit their depth of understanding within each subject area. They may focus on memorization or surface-level understanding rather than developing a deeper conceptual understanding that integrates knowledge from different areas. Keeping knowledge separate may lead to redundant learning experiences. Concepts or skills that are covered in multiple curricula may be revisited and relearned, wasting valuable time and effort.

To foster a more holistic and integrated approach to learning, it is important for students to make connections between different curricula and see the interrelatedness of knowledge. Encouraging interdisciplinary projects, promoting cross-curricular discussions, and emphasizing the application of knowledge in various contexts can help mitigate the negative consequences of keeping knowledge separate.

The value of the z-test statistic is 1. There is not sufficient evidence at the 0.02 level that the jeeps outperform the manufacturer's MPG rating.

To determine whether there is sufficient evidence at the 0.02 level that the jeeps outperform the manufacturer's MPG rating, we need to perform a hypothesis test.

In this case, our null hypothesis is that the jeeps do not outperform the manufacturer's MPG rating, and our alternative hypothesis is that the jeeps do outperform the manufacturer's MPG rating. We can use a one-sample z-test to test this hypothesis.

To perform the z-test, we need to calculate the z-test statistic, which is given by the following formula:

z = (mean - population mean) / (standard deviation/√ (sample size))

In this case, the sample mean is 55.9, the population means is 55.8, the standard deviation is 2.09, and the sample size is 220. Plugging these values into the formula above, we get:

z = (55.9 - 55.8) / (2.09 / √(220))

z = 0.05 / 0.05

z = 1

Therefore, the value of the z-test statistic is 1.

Next, we need to find the critical value for the z-test at the 0.02 level. We can use a z-table or a z-score calculator to find the critical value. For a one-tailed test at the 0.02 level, the critical value is 2.33.

Since the z-test statistic is less than the critical value, we cannot reject the null hypothesis at the 0.02 level. Therefore, there is not sufficient evidence at the 0.02 level that the jeeps outperform the manufacturer's MPG rating.

The length of the shortest side of a similar triangle is 12 cm. This can be calculated through corresponding parts of similar triangles or known as CPST.

Similar Triangles have the following features:

They have equal angles.

The ratio of corresponding sides is equal

Dimensions of the original triangle are 4 * 8 * 10

Therefore, the ratio of the longest side of both triangles is = 10 : 30

= 1 : 3

The ratio of the shortest side also equals 1 : 3

Shortest side in the original triangle = 4 cm

Let the shortest side of the similar triangle be x

Therefore, the ratio of shortest sides = ratio of longest sides

4 : x = 1 : 3

\(\frac{4}{x} =\frac{1}{3}\\ x=4*3\)

x = 12cm

Thus, the length of the shortest side is 12 cm
