how to make 9.37% into decimal​

While a common rule of thumb is to have a minimum sample size of 100 for continuous data to be statistically significant, the actual appropriate sample size may vary depending on the specific study design and research question. Option(D)

In statistics, the term "statistical significance" refers to whether an observed effect or relationship in the data is likely to be real and not just due to random chance. To determine statistical significance, we often perform hypothesis testing.

The sample size is a crucial factor in hypothesis testing. A larger sample size generally provides more reliable and precise estimates of population parameters and increases the statistical power of the test. With a larger sample size, even smaller effects or differences between groups can become statistically significant.

While there is no hard and fast rule for the minimum sample size to achieve statistical significance, a common guideline is to aim for at least 30 samples. This guideline is often used in the context of the Central Limit Theorem, which states that the sampling distribution of the sample mean becomes approximately normally distributed with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

In practice, the appropriate sample size depends on various factors, including the nature of the data, the effect size being studied, the desired level of confidence, and the statistical test used. Researchers often conduct sample size calculations based on these factors before conducting their studies to ensure they have an adequate sample size to achieve meaningful results and detect significant effects if they exist.

Answer: A

Step-by-step explanation:

When you write exponential form to radical form, the fraction tells us that kind of root it is. Since it is a cubed root, as indicated by the 3 in front of the radical, we know that the fraction will be \(\frac{1}{3}\). If it were to be \(\frac{1}{3}\), the entire radical would be to the power of 1. Since the radical is to the power of x, our answer would be \(125^{\frac{1}{3}x }\).

Question: In a sale, the price of a book is reduced by 25%. The price of the book in the sale is £12. Work out the original price of the book

Answer: £16

Step-by-step explanation:

To determine the original price of the book, we can use the fact that the sale price is 75% (100% - 25%) of the original price. Let's denote the original price as x.

75% of x = £12

To solve for x, we can set up the equation:

0.75x = £12

To isolate x, we divide both sides of the equation by 0.75:

x = £12 / 0.75

x = £16

Therefore, the original price of the book was £16.

Yes, the data provide evidence that there is a linear association between hours of television watched a week and GPA. This statement can be supported by statistical analysis of the data.

A linear association exists between two variables when the pattern of their plotted values on a scatterplot approximates a straight line. A linear association occurs when one variable increases while the other decreases. It is also known as a straight-line relationship.

The data you have asked about, which is the relationship between hours of television watched a week and GPA can be analyzed using statistical tools. The data can be graphed in a scatterplot to see whether there is a pattern between the variables. If a straight-line pattern is observed, then there is a linear association.

The statistical tools that can be used to analyze the data include the calculation of the correlation coefficient and regression analysis. The correlation coefficient is a measure of the strength of the association between two variables. It ranges from -1 to 1, with -1 indicating a perfect negative relationship, 0 indicating no relationship, and 1 indicating a perfect positive relationship.

Regression analysis can be used to determine the equation of the line of best fit for the data. This line represents the linear relationship between the two variables. By analyzing the slope of the line, we can determine the strength of the relationship between the variables.

The problem requires that we determine the maximum profit. The revenue equation is \(R(x,y) = 4x + 2y\) and the cost equation is C.

\((x,y) = x² - 3xy + 8y² + 6x - 47y - 3.\)

The profit equation can be found by subtracting the cost from the revenue.

\(P(x,y) = R(x,y) - C(x,y) = 4x + 2y - x² + 3xy - 8y² - 6x + 47y + 3 = -x² + 3xy - 8y² - 2x + 49y + 3\)

\(∂P/∂x = -2x + 3y - 2 = 0 ∂P/∂y = 3x - 16y + 49 = 0\).

Solving for x and y gives x = 25 and y = 14, which means that 25,000 type A solar panels and 14,000 type B solar panels should be produced per year to maximize profit. More than 100 words.

Jody has created a systematic sampling error by forgetting to include a segment of the population that is relevant to the study.

Systematic sampling is a sampling method where every nth member of a population is selected to be part of the sample. In Jody's case, she forgot to include a specific segment of the population, which means that the sampling process was not systematic. This error can introduce bias and affect the representativeness of the sample.

No calculations are required for this type of error.

3x = 33, so x = 11

These congruent alternate interior angles measure 110°.

The value of x in the parallel line is 11.

When parallel line are crossed by a transversal line, angle relationships are formed such as corresponding angles, alternate exterior angles, alternate interior angles, same side interior angles, vertically opposite angles etc.

Therefore, let's find the value of x using the angle relationship.

Hence,

7x + 33 = 10x (alternate interior angles)

33 = 10x - 7x

3x = 33

divide both sides by 3

x = 33 / 3

The survival time of a 60kg deer without food at -20 degrees Celsius depends on various factors, including its age, sex, and physical condition. However, assuming the deer is healthy and has 5kg of fat, it could potentially survive for around 30 to 50 days without food.

The exact survival time can vary depending on several factors, such as the deer's level of physical activity, environmental conditions, and how much energy it is expending to stay warm in the cold temperature. Additionally, if the deer is able to find sources of water, this can also increase its chances of survival.

It's important to note that this is just an estimate and that the actual survival time may vary. If the deer is injured or sick, its chances of survival may be reduced, and it may not be able to survive as long without food.

The height of the monument is 570 feet. Since the shadow of the monument and the shadow of the tourist are cast at the same time, their angles of elevation are the same.

To solve this problem, we need to use the concept of similar triangles. We can set up a proportion: (height of Monument) / (length of Monument's shadow) = (height of tourist) / (length of tourist's shadow)

Let x be the height of the Monument. Then we have:

x / 285 = 5 / 2.5

Cross-multiplying, we get:

2.5x = 5 * 285

Simplifying, we get:

x = 570

Therefore, the Monument is 570 feet tall.

To find the height of the monument, we can use the concept of similar triangles. Since the shadow of the monument and the shadow of the tourist are cast at the same time, their angles of elevation are the same.

Set up a proportion using the height and shadow length of the tourist and the monument:

(height of monument) / (shadow of monument) = (height of tourist) / (shadow of tourist)

Let x represent the height of the monument. Then:

x / 285 = 5 / 2.5

Now, solve for x:

x = (5 / 2.5) * 285
x = 2 * 285
x = 570 feet

The height of the monument is 570 feet.
