Step-by-step explanation:

The phase change line, also known as the phase boundary or phase transition line, is a line on a graph that represents a change in conditions for a substance. This line shows the temperature and pressure conditions at which a substance will change from one phase to another, such as from a solid to a liquid or from a liquid to a gas.

The phase change line is represented on a graph by a diagonal line that separates two regions where the substance is in different phases. This line usually slopes upwards from left to right, indicating that higher temperatures and pressures are needed to change the substance from one phase to another.

The phase change line is an important concept in thermodynamics and is used to understand the behavior of substances under different conditions. For example, the phase change line for water shows that at normal atmospheric pressure, water will freeze at 0°C and boil at 100°C. However, at higher pressures, the freezing and boiling points will change, and water may exist in different phases, such as a supercritical fluid.

Answer:

The nth term of the sequence is:

\(a_n=\frac{-3n+3}{2}+8\)

Step-by-step explanation:

Given the first 5 terms of the arithmetic sequence

8, 13/2, 5, 7/2, and 2

An arithmetic sequence has a constant difference 'd' and is defined by:

\(a_n=a_1+\left(n-1\right)d\)

as the common difference 'd' is:

\(d=a_{n+1}-a_n\)

Computing the differences of all the terms

\(\frac{13}{2}-8=-\frac{3}{2},\:\quad \:5-\frac{13}{2}=-\frac{3}{2},\:\quad \frac{7}{2}-5=-\frac{3}{2},\:\quad \:2-\frac{7}{2}=-\frac{3}{2}\)

\(d=-\frac{3}{2}\)

The first element is:

\(a_1=8\)

Therefore, the nth term is computed by:

\(a_n=a_1+\left(n-1\right)d\)

\(a_n=-\frac{3}{2}\left(n-1\right)+8\)

\(a_n=\frac{-3n+3}{2}+8\)

Therefore, nth term of the sequence is:

\(a_n=\frac{-3n+3}{2}+8\)

The major branch of statistics that deals with making inferences about a population based on a sample is called inferential statistics.

In this scenario, you collected data from a sample of eight classmates and calculated the average score to be 65.

Based on this sample, you made an inference about the entire class, stating that the average test score for the whole class was less than 70. This inference is an example of using inferential statistics. Inferential statistics allows us to draw conclusions and make predictions about a larger population based on a smaller sample.

By using statistical techniques and assumptions, we can estimate parameters, such as the population mean, using sample statistics. This helps us make informed decisions and generalizations about a population when it is not feasible or practical to collect data from the entire population.

Step-by-step explanation:

The angles between 0 and 2π that is coterminal to 780° are 2π and π/3.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The coterminal angle to 780°.

The coterminal angle is between 0 and 2π.

Now,

The coterminal angles can be positive or negative.

The coterminal angles are calculated by adding or subtracting 360 degrees as many times as needed from the reference angle.

Now,

780 - 360

= 780 - 360

= 360

= 2π

780 - (2 x 360)

= 780 - 720

The system of equations that matches the given graph is:

A. 3x - 6y = 12

9x - 18y = 36

To determine which system of equations matches a given graph, we need to analyze the slope and intercepts of the lines in the graph.

Looking at the options provided:

A. 3x - 6y = 12

9x - 18y = 36

B. 3x + 6y = 12

9x + 18y = 36

Let's analyze the equations in each option:

For option A:

The first equation, 3x - 6y = 12, can be rearranged to slope-intercept form: y = (1/2)x - 2.

The second equation, 9x - 18y = 36, can be simplified to 3x - 6y = 12, which is the same as the first equation.

In option A, both equations represent the same line, as they are equivalent. Therefore, option A does not match the given graph.

For option B:

The first equation, 3x + 6y = 12, can be rearranged to slope-intercept form: y = (-1/2)x + 2.

The second equation, 9x + 18y = 36, can be simplified to 3x + 6y = 12, which is the same as the first equation.

In option B, both equations also represent the same line, as they are equivalent. Therefore, option B does not match the given graph.

The probability that the sample mean differs from the actual mean by at least 12 hp is approximately 1. 8904 or 189.04%.

to determine the probability that the sample mean differs from the actual mean by at least 12 hp, we can use the central limit theorem and the properties of the normal distribution.

given:population mean (μ) = 220 hp

population standard deviation (σ) = 15 hpsample size (n) = 4

according to the central limit theorem, for a large enough sample size (n > 30), the sample mean follows a normal distribution, regardless of the shape of the population distribution.

to find the probability that the sample mean differs from the actual mean by at least 12 hp, we need to calculate the z-score for this difference and then find the corresponding cumulative probability.

first, we calculate the standard error of the mean (se) using the formula:

se = σ / √n

se = 15 / √4 = 7.5 hp

next, we calculate the z-score using the formula:z = (x - μ) / se

for a difference of at least 12 hp:

z = (12 - 0) / 7.5 = 1.6

using a standard normal distribution table or a calculator, we find the cumulative probability corresponding to z = 1.6 is approximately 0.9452.

however, we need to consider the probability of the sample mean differing by at least 12 hp in either direction, so we double this probability:p(mean differs by at least 12 hp) = 2 * 0.9452 = 1.8904

If cholesterol level were changed to being measured in grams instead of milligrams, the correlation between fat content and cholesterol level would not be affected.

This is because correlation is a measure of the strength and direction of the linear relationship between two variables, and converting the units of measurement does not change the underlying relationship between the variables. So, the correlation coefficient of 0.75 would remain the same whether cholesterol level is measured in milligrams or grams.

The correlation between fat content and cholesterol level for the 20 different brands of American cheese slices is 0.75. If you change the measurement of cholesterol level from milligrams to grams (1 gram = 1000 milligrams), it will not affect the correlation. The correlation coefficient will remain 0.75, as it is unit-less and only represents the strength and direction of the relationship between the two variables.

In all cases, the distance from the point (1, -5, 7) to the given plane or axis is 0.

To find the distance from a point to a plane or axis, we can use the formula for the distance between a point and a plane or axis in three-dimensional space. The formula is given by:

Distance = |Ax + By + Cz + D| / √(A² + B² + C²)

where (x, y, z) is the point, and the plane or axis is represented by the equation Ax + By + Cz + D = 0.

Let's calculate the distances for each case:

(a) Distance to the xy-plane:

The equation of the xy-plane is z = 0.

Substituting the values of the point (1, -5, 7) into the equation, we get:

1(0) - 5(0) + 7D + D = 0

8D = 0

D = 0

Using the formula, the distance is:

Distance = |1(0) + (-5)(0) + 7(0) + 0| / √(1² + (-5)² + 7²)

= 0 / √(1 + 25 + 49)

= 0

Substituting the values of the point (1, -5, 7) into the equation, we get:

0 + 5(0) - 7(0) + D = 0

0 + 0 - 0 + D = 0

D = 0

Using the formula, the distance is:

Distance = |1(0) + (-5)(0) + 7(0) + 0| / √(1² + (-5)² + 7²)

= 0 / √(1 + 25 + 49)

= 0

(c) Distance to the xz-plane:

The equation of the xz-plane is y = 0.

Substituting the values of the point (1, -5, 7) into the equation, we get:

0 - 5(0) + 7(0) + D = 0

0 - 0 + 0 + D = 0

D = 0

Using the formula, the distance is:

Distance = |1(0) + (-5)(0) + 7(0) + 0| / √(1² + (-5)² + 7²)

= 0 / √(1 + 25 + 49)

= 0

(d) Distance to the x-axis:

The equation of the x-axis is y = 0, z = 0.

Substituting the values of the point (1, -5, 7) into the equation, we get:

0 - 5(0) + 7(0) + D = 0

0 - 0 + 0 + D = 0

D = 0

Using the formula, the distance is:

Distance = |1(0) + (-5)(0) + 7(0) + 0| / √(1² + (-5)² + 7²)

= 0 / √(1 + 25 + 49)

= 0

(e) Distance to the y-axis:

The equation of the y-axis is x = 0, z = 0.

Substituting the values of the point (1, -5, 7) into the equation, we get:

0 + 5(0) + 7(0) + D = 0

0 + 0 + 0 + D = 0

D = 0

Using the formula, the distance is:

Distance = |1(0) + (-5)(0) + 7(0) + 0| / √(1² + (-5)² + 7²)

= 0 / √(1 + 25 + 49)

= 0

(f) Distance to the z-axis:

The equation of the z-axis is x = 0, y = 0.

Substituting the values of the point (1, -5, 7) into the equation, we get:

0 - 5(0) + 7(0) + D = 0

0 - 0 + 0 + D = 0

D = 0

Using the formula, the distance is:

Distance = |1(0) + (-5)(0) + 7(0) + 0| / √(1² + (-5)² + 7²)
