Step-by-step explanation:

For a point to be a solution to a system of inequalities, the points must make the signs of the inequalities true.

For example, the points must give results like 2<3 or 0>-2, these are true solutions. If the points gives 1>2, then that point is not a solution.

The height of the cylinder is 4 feet.

The volume of a cylinder can be found as follows;

volume of a cylinder = base area × height

Therefore,

base area = πr²

volume of the cylinder = 48π ft³

base area = 12π ft²

Therefore, let's find the height of the cylinder as follows:

48π = 12π × h

divide both sides of the equation by 12π

h = 48π / 12π

h = 4 ft

Therefore,

The scatterplot with the least squares line provides insights into the relationship between average annual global surface temperature and the years from 2000 to 2015, allowing us to assess trends, strength of correlation, and make predictions within certain limitations.

The scatterplot represents the relationship between the average annual global surface temperature, in degrees Celsius, and the corresponding years from 2000 to 2015. The line drawn on the plot is the least squares line, which is the best fit line that minimizes the overall distance between the observed data points and the line.

The least squares line is determined using a statistical method called linear regression. It calculates the equation of a straight line that represents the trend in the data. This line serves as a mathematical model to estimate the average temperature based on the year.

By analyzing the scatterplot and the least squares line, we can make several observations. Firstly, we can see whether the temperature has been increasing, decreasing, or remaining relatively stable over the given years. If the slope of the line is positive, it indicates a positive correlation, implying that the temperature has been increasing. Conversely, a negative slope suggests a decreasing trend.

Additionally, we can evaluate the strength of the relationship between temperature and time by examining how closely the data points cluster around the line. If the points are closely grouped around the line, it suggests a strong correlation, indicating that the line is a good representation of the data. On the other hand, if the points are more scattered, the correlation may be weaker.

Furthermore, the line can be used to predict the average annual global surface temperature for future years beyond the data range of 2000 to 2015. However, it's important to note that such predictions should be made with caution and considering other factors that may affect global temperatures, such as climate change and natural variability.

The conditions to allow skewed variables are: they are naturally occurring phenomenon that can't be controlled, it serves as control variable, and if it has significant impact on the outcome variable, it may be necessary to include.

Yes, there are certain conditions in which it may be acceptable to allow skewed variables into a research study. One such condition is when the variable is a naturally occurring phenomenon and cannot be manipulated or controlled. In such cases, it may be necessary to include the variable in the study despite its skewed nature.

Another condition is when the skewed variable is not the primary focus of the research, but rather serves as a control variable or confounding variable. In such cases, the focus of the study may be on other variables, and the skewed variable may be included simply to control for its effects on the outcome variable.

Additionally, if the skewed variable is expected to have a significant impact on the outcome variable, it may be necessary to include it in the study despite its skewed nature. In such cases, researchers may use statistical techniques to account for the skewedness and ensure that the results are still valid and reliable.

Overall, while skewed variables can present challenges in research studies, there may be certain conditions in which their inclusion is necessary or acceptable.

The average velocity of the particle over the interval from t=1.0 s to t=3.0 s is -2.8 m/s.

The average velocity of an object is defined as the change in its position divided by the change in time. In this case, we need to find the change in position between t=1.0 s and t=3.0 s.

Given the equation for the position of the particle, x = 2.0 - 3.6t + 1.1t^2, we can calculate the position at t=1.0 s and t=3.0 s by substituting the values:

At t=1.0 s:

x = 2.0 - 3.6(1.0) + 1.1(1.0)^2 = -0.5 meters

At t=3.0 s:

x = 2.0 - 3.6(3.0) + 1.1(3.0)^2 = -20.1 meters

The change in position (Δx) over the interval is then:

Δx = (-20.1) - (-0.5) = -19.6 meters

The change in time (Δt) is 3.0 s - 1.0 s = 2.0 s.

Therefore, the average velocity (v) is given by:

v = Δx / Δt = (-19.6 meters) / (2.0 s) = -9.8 m/s

Hence, the average velocity of the particle over the interval from t=1.0 s to t=3.0 s is -9.8 m/s.

Answer:

the answer is 20

the lateral area of the given regular prism is 100 square centimeters.

Given:

Base of the prism is a square with a side of 2 cm.

Height of the prism is 125 mm.

First, let's convert the height to centimeters since the base side length is given in centimeters:

125 mm = 12.5 cm (as there are 10 mm in 1 cm).

The lateral area of a prism can be calculated by multiplying the perimeter of the base by the height. Since the base of the prism is a square, the perimeter is given by 4 times the length of one side.

Perimeter of the base = 4 * side length

Substituting the given side length:

Perimeter of the base = 4 * 2 cm = 8 cm

Now, we can calculate the lateral area:

Lateral area = Perimeter of the base * Height

Lateral area = 8 cm * 12.5 cm

Lateral area = 100 cm²

Therefore, the lateral area of the given regular prism is 100 square centimeters.

Retaining a higher percentage of earnings can result in a higher growth rate by providing more capital for reinvestment and fueling business expansion.

The formula for the Gordon Growth Model is as follows:

Expected Growth Rate = (Dividend / Stock Price) + Rate of Return

In this case, the dividend is given as $0.78, and the stock price is $16.25. The rate of return is stated as 7.80%. Plugging these values into the formula, we get:

Expected Growth Rate = (0.78 / 16.25) + 0.078 = 0.048 + 0.078 = 0.126

Converting this to a percentage, the expected growth rate is 12.6%. Therefore, Robert's forecast of PAMC's growth rate would be 12.6%.

The growth in earnings can contribute to the growth in dividends. Long-run earnings growth can result from various factors such as increased sales, cost management, innovation, and market expansion.

In terms of retaining a higher percentage of earnings, it can indeed result in a higher growth rate. When a company retains a higher portion of its earnings, it has more capital available for reinvestment into the business. This can be used for research and development, acquisitions, expanding operations, and other initiatives that can fuel growth. By retaining more earnings, a company can generate higher profits, which can ultimately lead to an increased growth rate.

To summarize, the relationship between earnings and dividends is that dividends are typically paid out of earnings, and growth in earnings can contribute to the growth in dividends. However, long-run earnings growth occurs due to various factors beyond just paying dividends.
