Opportunity cost is the price of giving up an option. An opportunity cost is the price you pay for selecting a particular option over another. Opportunity cost is the benefits you lose by choosing one alternative over another one.”

The value of the next-highest-valued alternative use of a resource is what economists mean when they talk about its "opportunity cost." You cannot, for instance, read a book at home during the time you would have spent seeing a movie and spend the money you would have spent on something else.

Opportunity cost is frequently referred to as the second-best option. The loss of benefit that would have been realized if a different option had been taken is sometimes referred to as the alternative cost. The loss of advantage as a result of a change in decision is another way to explain it.

The Simplified value of the "algebraic-expression" (12x³y² - 18xy)/6xy is 2x²y - 3.

An "Algebraic-Expression" represents a combination of numbers, variables, and arithmetic operations such as addition, subtraction, multiplication, and division, that represents a mathematical relationship or rule.

To simplify the expression, (12x³y² - 18xy)/6xy,  we factor out a common factor of "6xy" from the numerator;

We get,

⇒ (12x³y² - 18xy)/6xy = 6xy(2x²y - 3)/6xy,

The 6xy in the numerator and denominator cancel out,

We get,

⇒ 2x²y - 3

Therefore, the simplified expression is 2x²y - 3.

Interquartile range = 40

Step-by-step explanation:

interquartile range = Q3-Q1

Q1 = 50 (middle of the lower quartile)

Q3= 90 (middle of the higher quartile)

The appropriate domain for the function would be:

{0, 1, 2, 3, 4, 5, ...}

The domain of a function represents the set of all possible values that the independent variable (in this case, the number of candles sold) can take.

In the context of the problem you described, the function's domain should be limited to the realistic range of possible values for the number of candles sold. For example, it wouldn't make sense for the domain to include negative values, since it's not possible to sell a negative number of candles.

Assuming there are no other constraints on the number of candles sold, a reasonable domain for the function could be any non-negative integer since it's unlikely that the seniors would sell a fractional number of candles.

Therefore, the appropriate domain for the function would be:

{0, 1, 2, 3, 4, 5, ...}

This set includes all non-negative integers, representing all the possible values for the number of candles sold.

The number of hamburgers sold on Friday was 442.

Let us form the linear equation to find the number of burgers;

Let the cheeseburger be represented by x.

Since there were 67 more cheeseburgers sold than hamburgers. This means that hamburgers will be:

The number of hamburgers = x + 67.

Since the local hamburger shop sold a combined total of 817 hamburgers and cheeseburgers. This will be:

x + x + 67 = 817

2x + 67= 817

2x = 817 - 67

2x = 750

x = 750 / 2

x = 375

So, 375 cheeseburgers were sold on Friday.

Therefore, the number of hamburgers sold will be:

= 817 - 375

= 442

Thus, the number of hamburgers sold on Friday was 442.

A record's key field is the field whose contents make the record unique among all records in a file.

In computer science and database management, a record's key field, also known as a primary key, is a unique identifier that is used to distinguish one record from another in a database. A key field can be a single field or a combination of fields that uniquely identify a record.

For example, in a database of employee records, the social security number or employee ID number may be used as the key field to identify each employee record. This key field must be unique for each record in the database, and it is typically indexed to allow for faster searching and sorting of records.

The key field plays a crucial role in ensuring data integrity and consistency in a database. It is used to enforce data constraints and relationships between tables, and it is often used as a reference by other tables in a database.

In summary, a record's key field is an important component of a database that uniquely identifies each record and allows for efficient management and organization of data.

The statement is False. The expression evaluates to 2.0, not 2.5.

The expression (double) (10 / 4) involves several steps of evaluation. Let's break it down to understand the process.

Integer Division: The division operation 10 / 4 is performed first. In integer division, the result is the quotient of the division without any decimal places. In this case, 10 / 4 equals 2, as the fractional part is truncated.

Type Casting: The expression (double) is a type cast that converts the result of the division to a double data type. However, the type casting occurs after the integer division has already taken place. So, the result of the type casting will not affect the value obtained in the integer division.

As a result, the expression (double) (10 / 4) evaluates to 2.0, not 2.5. The value 2.0 is a double representation of the integer 2. The type casting only affects the data type of the value, not its actual numerical value.

Therefore, the statement "The following expression will evaluate to 2.5: (double) (10 / 4)" is false. The expression evaluates to 2.0.

From the unit conversion is found that: 6 cm=0.06 m = \(\frac{6}{100}\) m and                4 mm=0.004 m = \(\frac{4}{1000}\) m.

The unit of a length is the essential information and there are different units for the length. In the International System Units (SI), the standard unit for length is the meter (m).  Nonetheless, there are others units, for example: inches (in) and  yard (yd).

For solving this exercise, you need to know the relation between the units of the length in the  SI unit.

1 kilometer (km) = 1000 meters (m)

1 hectometer (hm) = 100 meters (m)

1 dekameter (dam) = 10  meters (m)

1 meter (m)

1 decimeter (dm) = 0.1 meters (m)

1 centimeter (cm) = 0.01 meters (m)

1 milimeter (mm) = 0.001 meters (m)

Now you can solve the question

        1 cm ------- 0.01 m

        6 cm ------ x

        x=6*0.01 =0.06 m = \(\frac{6}{100}\) m

        1 mm ------- 0.001 m

The x-intercepts for the function f(x) = x^2 + 2x - 15 are x = -5 and x = 3.

To find the x-intercepts, we set the function equal to zero and solve for x. In this case, we have the equation:

x^2 + 2x - 15 = 0

To factor this quadratic equation, we look for two numbers that multiply to -15 and add up to 2. The numbers that satisfy this condition are -5 and 3.

Therefore, the factored form of the equation is:

(x - 3)(x + 5) = 0

Setting each factor equal to zero, we find the x-intercepts:

x - 3 = 0 --> x = 3

x + 5 = 0 --> x = -5

Hence, the x-intercepts for the function f(x) = x^2 + 2x - 15 are x = -5 and x = 3.

Variability provides a quantitative measure of the differences between scores in a distribution and describes the degree to which the scores are spread out to clustered together. The purpose for measuring variability is to obtain an objective measure of how the scores are spread out in a distribution

Variability also measure how accurately individual score or sample represent the entire population

When the standard deviation is 0 , the scores have no variability.

Variability describes how far the data points are from each other and from the center of the distribution. In addition to measures of central tendency, measures of variability provide descriptive statistics that summarize the data.

\((-7, 6) \to\) Quadratics in Motion

\((-2, 14) \to\)Towers of Trigonometry

\((5,8) \to\) The Food Equation

\((-1,7)\to\) First aid station

Solving (a): Plot the above points

See attachment for plot

Solving (b): Determine if the first aid station is at the center of the park

From the plot, we have the opposite points to be:

(1) \((0,0)\) and  \((-2, 14)\)

(2) \((5,8)\)  and \((-7, 6)\)

Calculate midpoint using:

\(M = \frac{1}{2}(x_1 + x_2, y_1 + y_2)\)

For (1):

\(M = \frac{1}{2}(0 -2, 0 + 14)\)

\(M = \frac{1}{2}(-2,14)\)

\(M = (-1,7)\)

For (2):

\(M = \frac{1}{2}(5 -7, 8 + 6)\)

\(M = \frac{1}{2}(-2,14)\)

\(M = (-1,7)\)

From the above computation, we have midpoint to be:

\(M = (-1,7)\)

Given that:

\((-1,7)\to\) First aid station

The probability of renting exactly three apartments in a week is approximately 0.2018 or 20.18%.

If the average number of units rented per week is 2.3 and the distribution is Poisson, then the parameter lambda is also equal to 2.3.

The probability of renting exactly three apartments in a week is given by the Poisson probability function:

\(P(X = 3) = (e^(-lambda) * lambda^x) / x!\)

Substituting the values, we get:

\(P(X = 3) = (e^(-2.3) * 2.3^3) / 3!\)

P(X = 3) = (0.09963 * 12.167) / 6

P(X = 3) = 0.2018

Therefore, the probability of renting exactly three apartments in a week is approximately 0.2018 or 20.18%.
