The phrase "He went to get milk but never came back" is often used as a humorous way to explain someone's absence or to imply that someone is unreliable or untrustworthy.

The phrase likely originates from a common experience where a child's parent, often their father, promises to go out to get something, like milk, but never returns. This can be a source of disappointment and confusion for the child, and the phrase has since been used in a joking manner to explain someone's failure to show up or fulfill a promise.

However, it is important to recognize that this experience can also be a source of trauma and should not be used to make light of someone's pain or loss.

The correct description of the values of the values in the domain and the range of the function and the appropriate value set are:

The domain and the range of a function are the factors of the function, such that the domain defines the set of possible input values of the function, while the range, gives the set of possible output values of the function.

The given function for the weight of the airplane is given as W = 5·F + 3000

Where:

W = The weight of the airplane

F = The volume of fuel in the tank

Given that \(\displaystyle{\mathbf{Density}=\frac{Mass}{Volume} }\), we have that the coefficient, 5, may represent the density of the airplane, while the constant, 3,000, ma represent the rest of the fixed part of the airplane.

Given that the weight of the airplane, W, depends on the amount of fuel, F, the weight of the airplane is the dependent variable that gives the range of the function, while the amount of fuel, F, is the independent variable that gives the domain of the function.

The possible values for the weight of the airplane, (the range), is 3,000 ≤ W ≤ ∞

The possible values for the amount of fuel, which gives the domain is 0 ≤ F < ∞

However, taking the maximum volume of fuel the tank can hold as 400 gallons, which is a realistic value, as the tank cannot hold an infinite, ∞, amount of fuel, gives;

Domain: 0 ≤ F ≤ 400

Range: 5 × 0 + 3,000 ≤ W ≤ (5 × 400 + 3,000) = 3,000 ≤ W ≤ 5,000

The correct options are therefore:

Domain: Amount of fuel in airplane tank (in gallons)

Set of values: The set of all real numbers from 0 to 400

Range: Weight of airplane in pounds

Set of values: The set of all real numbers from 3,000 to 5,000

Step-by-step explanation:

The interior angles of any triangle must add up to 180° in measure. Right angles have measure 90°, so the missing angles in both triangles here have measure 45°.

In a 45°-45°-90° triangle, the legs and hypotenuse occur in a ratio of 1 : √2. This means

(1) x = 48 √2

(2) 88 = √2 x   →   x = 88 / √2 = 44 √2

You could also set up trigonometric equations to solve for x in each case:

(1) cos(45°) = 48 / x   →   x = 48 / cos(45°) = 48 / (1 / √2) = 48 √2

(2) cos(45°) = x / 88   →   x = 88 cos(45°) = 88 (1 / √2) = 44 √2

When an arch is extended overhead into a half cylinder, it is known as a barrel vault.

A barrel vault is a curved architectural structure that resembles the shape of a half-cylinder. It is created by placing a series of arches side by side, forming a continuous and uninterrupted vaulted ceiling. The term "barrel" refers to the resemblance of the vault to the shape of a barrel or a tunnel.

Barrel vaults have been used in architecture for centuries and are often found in historical buildings and structures. They provide a sturdy and durable construction method, distributing the weight of the ceiling evenly along the arches. This allows for the creation of large and open interior spaces without the need for additional support columns.

Barrel vaults are commonly used in churches, cathedrals, and other monumental structures, where they serve both functional and aesthetic purposes. The sweeping and graceful curves of the barrel vaults add a sense of grandeur and elegance to architectural designs, making them a popular choice in various architectural styles throughout history.

Answer:

40.3°

Step-by-step explanation:

sin x/ (5.3) = sin 90/ (8.2)

sin x = (5.3 sin 90) / 8.2

= 5.3/8.2

x = arcsin (5.3/8.2)

= 40.3° to 1 dp

The measure of angle x using Trigonometry is 40.263215° or 40.3.

Trigonometry is a branch of mathematics that deals with the study of relationships involving the angles and sides of triangles. It is especially useful in understanding the properties and behavior of right-angled triangles.

Sine ratio is defined as the ratio of the length of the side opposite an angle to the length of the triangle's hypotenuse.

From the figure,

Perpendicular = 5.3 m

Hypotenuse = 8.2 m

Using Trigonometry

sin x = P / H

sin x = 5.3/ 8.2

sin x = 0.6463

Using Inverse Trigonometry

x = \(sin^{-1}\)(0.6463)

x= 40.263215°

Thus, the measure of angle x is 40.3.

The given function f(x) = (x^2 - 16) / (\(x^2 + 16\)) simplifies to f(x) = 1 / (\(x^2 + 16\)).

To analyze the given function f(x) = \((x^2 - 16) / (x^2 + 16),\) we will simplify the expression and perform further calculations:

First, let's factor the numerator and denominator to simplify the expression:

f(x) =\((x^2 - 16) / (x^2 + 16),\)

The numerator can be factored as the difference of squares:

\(x^2 - 16\)= (x + 4)(x - 4)

The denominator is already in its simplest form.

Now we can rewrite the function as:

f(x) = [(x + 4)(x - 4)] / (\(x^2 + 16\))

Next, we notice that (x + 4)(x - 4) appears in both the numerator and denominator. Therefore, we can cancel out this common factor:

f(x) = (x + 4)(x - 4) / (\(x^2 + 16\)) ÷ (x + 4)(x - 4)

(x + 4)(x - 4) in the numerator and denominator cancels out, resulting in:

f(x) = 1 / (\(x^2 + 16\))

Now we have the simplified form of the function f(x) as f(x) = 1 / (\(x^2 + 16\)).

To summarize, the given function f(x) simplifies to f(x) = 1 / (\(x^2 + 16\)) after factoring and canceling out the common terms.

The claims made by the Princeton Review advertisers regarding the average score improvement may be exaggerated.

a. H_0: The average score improvement for students who took the Princeton Review course is 110 points.

  H_a: The average score improvement for students who took the Princeton Review course is less than 110 points.

b. To test the claim using the p-value approach, we calculate the test statistic and find the corresponding p-value. The sample mean score improvement is 107 points, and the standard deviation is 13 points. We can use a one-sample t-test to compare the sample mean to the claimed average improvement of 110 points. The p-value represents the probability of obtaining a sample mean as extreme as or more extreme than the observed mean if the null hypothesis is true. If the p-value is smaller than the significance level, we can reject the null hypothesis. In this case, we calculate the p-value and compare it to various significance levels (e.g., 0.01, 0.05, and 0.10) to determine at which levels we can reject H_0.

c. Using the critical value approach, we compare the test statistic (calculated as (sample mean - claimed mean) / (standard deviation / √n)) to the critical value corresponding to the chosen significance level (alpha). If the test statistic is more extreme than the critical value, we reject H_0. For alpha = 0.1, we find the critical value from the t-distribution and compare it to the test statistic to determine if we can reject the null hypothesis.

d. To calculate an appropriate confidence interval, we can use a one-sided confidence interval to test the hypotheses. The confidence interval can be constructed to estimate the true average score improvement with a specified level of confidence. If the interval does not include the claimed minimum improvement of 110 points, it would provide evidence against the Princeton Review's claim.

e. As a competitor, the conclusion could be stated as follows: "Our company's review course provides a significant average score improvement for high school students taking the SAT tests, with a proven result higher than the claimed minimum improvement by the Princeton Review."

f. As a representative of the Princeton Review, the conclusion could be stated as follows: "Our review course demonstrates a strong average score improvement for high school students taking the SAT tests. While the observed mean improvement in this particular sample was slightly below the claimed minimum, it is important to consider the overall effectiveness and impact of our course, which has proven success in helping students achieve significant score improvements."
