Ann(S) satisfies both closure under addition and closure under multiplication by elements of R, it is an ideal of R. In conclusion, we have shown that Ann(S) is non-empty, and it is an ideal of the commutative ring R.

To show that Ann(S) is non-empty, we need to find at least one element in Ann(S).

Let's consider the zero element of R, denoted as 0. For any x ∈ S, we have 0 * x = 0, which satisfies the condition for Ann(S) since 0 * x = 0 for all x ∈ S. Therefore, 0 ∈ Ann(S), and Ann(S) is non-empty.

To prove that Ann(S) is an ideal of R, we need to show that it satisfies the two defining properties of an ideal:

1. Closure under addition: Let a, b ∈ Ann(S). We need to show that a + b ∈ Ann(S).

For any x ∈ S, we have (a + b) * x = a * x + b * x = 0 + 0 = 0. Since a and b satisfy the condition for Ann(S), their sum a + b also satisfies the condition. Therefore, a + b ∈ Ann(S).

2. Closure under multiplication by elements of R: Let a ∈ Ann(S) and r ∈ R. We need to show that r * a ∈ Ann(S).

For any x ∈ S, we have (r * a) * x = r * (a * x) = r * 0 = 0. Since a satisfies the condition for Ann(S), its product with any element r ∈ R also satisfies the condition. Therefore, r * a ∈ Ann(S).

Since Ann(S) satisfies both closure under addition and closure under multiplication by elements of R, it is an ideal of R.

In conclusion, we have shown that Ann(S) is non-empty, and it is an ideal of the commutative ring R.

Sampling is the statistical process of selecting a subset (called a “sample”) of a population of interest for purposes of making observations and statistical inferences about that population.

Social science research is generally about inferring patterns of behaviors within specific populations.

We cannot study entire populations because of feasibility and cost constraints, and hence, we must select a representative sample from the population of interest for observation and analysis.

It is extremely important to choose a sample that is truly representative of the population so that the inferences derived from the sample can be generalized back to the population of interest.

Improper and biased sampling is the primary reason for often divergent and erroneous inferences reported in opinion polls and exit polls conducted by different polling groups such as CNN/Gallup Poll, ABC, and CBS, prior to every U.S. Presidential elections.

Hence, three pounds of ice cream contain 1968 calories as we can apply a ratio to determine how many calories are contained in 3 pounds .

Researchers utilise a method called the unitary approach to tackle proportional issues. It entails identifying a single product value that can be utilized to calculate the values of connected units. The method is predicated on the notion that if the value of one unit of even a quantity is known, then the value of any further unit of the same quantity can be determined. It is frequently employed in the computation of costs, rates, and dimensions.

given

Let's begin by converting 5 ounces to pounds:

A pound weighs 16 ounces.

5 ounces equals 5/16 pounds.

So, we can apply a ratio to determine how many calories are contained in 3 pounds:

(3 pounds/x calories)/5/16 pounds/410 calories

After finding x, we obtain:

3 pounds * 410 calories divided by 5/16 pounds equals 1968 calories.

The expected value per ticket from the standpoint of the charity is $0.27.

The expected value represents the average amount that the charity earns by selling one ticket. In this case, the charity plans to sell 1100 tickets at a cost of $1.00 each, resulting in a total revenue of $1100.00. Since there is only one prize worth $400.00, the charity's net earnings will be $700.00 ($1100.00 - $400.00) if all the tickets are sold.

To calculate the expected value per ticket, we divide the net earnings by the number of tickets sold, which is $0.64 ($700.00 / 1100). Rounded to the nearest cent, the expected value per ticket is $0.27.

The expected value is a useful concept for assessing the potential outcomes of an event. In this context, it helps the charity estimate the average amount they can expect to earn per ticket sold. It is important to note that the expected value is not necessarily the actual amount that will be earned from each ticket, as individual outcomes can vary. However, it provides a baseline estimate based on probabilities and can help the charity make informed decisions about their fundraising efforts.

1) For A Plus Plumbing

A. The cost per hour of work is $60 per hour.

B. The one-time fee is $320.

2) For Quality Plumbing:

The cost for x hours of work is given by the equation cost = 50x - 50

1) For A Plus Plumbing:

A. To calculate the cost per hour of work, we need to find the slope of the line connecting two points on the table. Let's use the first two rows:

slope = (cost2 - cost1) / (time2 - time1) = (140 - 80) / (2 - 1) = 60

So the cost per hour of work for A Plus Plumbing is $60 per hour.

B. The one-time fee is given in the table as the cost when time is zero. From the table, we can see that the one-time fee for A Plus Plumbing is $320.

2) For Quality Plumbing,

We can see from the graph that the cost starts at $50 for two hours of work and increases by $50 for each additional hour. This means that the cost for x hours of work can be calculated using the equation:

cost = 50 + 50(x-2) = 50x - 50

The distance between successive fourth roots of the complex number √3/2 - 1/2i on the unit circle is 5π/24 units.

To find the distance between successive fourth roots of a complex number on the unit circle, we can use the concept of the angle between the roots. Let's proceed step by step:

The given complex number is √3/2 - 1/2i. This complex number lies on the unit circle because its magnitude is equal to 1.

1. Convert the given complex number to trigonometric form:

  √3/2 - 1/2i = cos(θ) + i*sin(θ)

  By comparing the real and imaginary parts, we can determine the angle θ:

  cos(θ) = √3/2

  sin(θ) = -1/2

  Using the unit circle, we can find that θ = 5π/6 (or 150 degrees). This angle represents the position of the given complex number on the unit circle.

2. Find the angle between successive fourth roots:

  Since we are interested in the fourth roots, we divide the angle θ by 4:

  θ/4 = (5π/6) / 4 = 5π/24

  This angle represents the angular distance between two successive fourth roots on the unit circle.

3. Calculate the distance between the two points:

  To find the distance, we multiply the angular distance by the radius of the unit circle (which is 1):

  Distance = (5π/24) * 1 = 5π/24

  Therefore, the distance between successive fourth roots of the complex number √3/2 - 1/2i on the unit circle is 5π/24 units.

The simple interest was $10.5 and the amount after 1 year would be $360.5 in her account.

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100

We have been given data as

Principal amount (P) = $350

Time (T) = 1 year

The rate of interest (R) = 3%

Simple interest= P × R × T

Simple interest = 350 × 3/100 × 1

Simple interest = $10.5

So the amount after 1 year would be P + S.I. = 350 + 10.5 = $360.5

Therefore, the simple interest would be $10.5 and the amount after 1 year would be $360.5.

To find the value(s) of the variable(s), you need to have an equation or problem statement that relates the variable(s) to other known quantities. Once you have this equation or statement, you can solve for the variable(s) by manipulating the equation algebraically.

For example, if the problem states that 2x + 5 = 17, you can solve for x by first subtracting 5 from both sides to get 2x = 12. Then, you can divide both sides by 2 to get x = 6. So, the value of the variable x is 6.

In some cases, you may need to use more advanced methods such as factoring or the quadratic formula to solve for the variable(s). Regardless of the method used, it's important to check your answer(s) by plugging them back into the original equation to make sure they satisfy the given conditions.

In terms of rounding decimal answers to the nearest tenth, this means that if the answer is a decimal with more than one digit after the decimal point, you would round to the nearest tenth place (i.e. the digit immediately to the right of the decimal point).

The inverse Laplace transform of F(s) is:

\(f(t) = e^(-t)\)

To find the inverse Laplace transform of each function, we need to express them in terms of known Laplace transforms. Here are the solutions for each function:

a)

\(F(s) = \large{\frac{2e^{-0.5s}}{s^2-6s+9}}\)

To find the inverse Laplace transform, we first need to factor the denominator of F(s). The denominator factors as (s - 3)². Therefore, we can rewrite F(s) as:

\(F(s) = \large{\frac{2e^{-0.5s}}{(s-3)^2}}\)

Now, we know that the Laplace transform of eᵃᵗ is 1/(s - a). Therefore, the inverse Laplace transform of

\(e^(-0.5s) \: is \: e^(0.5t).\)

Applying this, we get:

\(f(t) = 2e^(0.5t) * t \\

b) F(s) = \large{\frac{s-1}{s^2-3s+2}}\)

We can factor the denominator of F(s) as (s - 1)(s - 2). Now, we rewrite F(s) as:

\(F(s) = \large{\frac{s-1}{(s-1)(s-2)}}\)

Simplifying, we have:

\(F(s) = \large{\frac{1}{s-2}}\)

The Laplace transform of 1 is 1/s. Therefore, the inverse Laplace transform of F(s) is:

\(f(t) = e^(2t) \\

c) F(s) = \large{\frac{s-1}{s^2+s-2}}

\)

We factor the denominator of F(s) as (s - 1)(s + 2). The expression becomes:

\(F(s) = \large{\frac{s-1}{(s-1)(s+2)}}\)

Canceling out the (s - 1) terms, we have:

\(F(s) = \large{\frac{1}{s+2}}\)

The Laplace transform of 1 is 1/s. Therefore, the inverse Laplace transform of F(s) is:

\(f(t) = e^(-2t) \\

d) F(s) = \large{\frac{e^{-s}(s-1)}{s^2+s-2}}\)

We can factor the denominator of F(s) as (s - 1)(s + 2). Now, we rewrite F(s) as:

\(F(s) = \large{\frac{e^{-s}(s-1)}{(s-1)(s+2)}}\)

Canceling out the (s - 1) terms, we have:

\(F(s) = \large{\frac{e^{-s}}{s+2}}\)

The Laplace transform of

\(e^(-s) \: is \: 1/(s + 1).\)
