Step-by-step explanation:

To formulate and solve a linear programming model for the resource-allocation problem in Excel, you will need to use the appropriate formulas in each cell. Additionally, you can utilize Solver to optimize the solution.

In Excel, you can use the SUMPRODUCT formula to calculate the contribution per unit by multiplying the profit per unit of each activity by the corresponding allocation. For example, if the profit per unit of activity A is in cell B2 and the allocation for activity A is in cell C2, you can use the formula "=B2*C2" to calculate the contribution per unit for activity A.

To formulate the linear programming model, you will need to define the objective function and the constraints. The objective function represents the goal you want to maximize or minimize, while the constraints specify the limitations on the resources or activities.

To set up Solver, go to the Data tab in Excel and click on Solver. In the Solver Parameters dialog box, you need to specify the objective cell (the cell containing the formula for the total contribution), select the optimization type (maximize or minimize), and add the constraints. The constraints can be added by clicking on the Add button and specifying the cell references for the constraints.

Once Solver is set up, you can click Solve to find the optimal solution that maximizes or minimizes the objective function while satisfying the constraints.

Answer: The answer is that the length is square ft, and the width is  .

Step-by-step explanation:

The length and width of the wall of the barn are 18, 9

The area of rectangle is product of length and width

Given area of rectangle is 90 ft²

given length = 8 ft + 2ₓ width

l = 8 +2 w

area = l × w

90 = (8 +2 w) × w

90= 8w +2w²

2w²+ 8w -90 =0 or w²+4w - 45 =0

On solving w= 9, -5

as width cannot be negative so w= 9

l= 8+2×9

l=26

Thus the length and width of the wall of the barn are 18, 9

Statement: If p, then q

Inverse: If q, then p

Converse: If not p, then not q

Contrapositive: If not q, then not p.

We can see from the statement that p = brush teeth twice a day and q = not get cavities.

Thus:

Inverse: If I don't get cavities, then I brush my teeth twice a day. FALSE (for example, I might floss extra well instead. Brushing my teeth twice a day is not the only way to avoid cavities)

Converse: If I don't brush my teeth twice a day, then I get cavities. FALSE (for example, I might not eat a lot of sugar and thus I don't get cavities)

Contrapositive: If I get cavities, then I did not brush my teeth twice a day. TRUE

If this confuses you, try the example of p = cat and q = four legs. (i.e. the statement is If this is a cat, it has four legs). Try making the inverse, converse, and contrapositive, and see the truth of those statements.

Failure to include some units, or entire portions, of the defined survey population in the actual operational sample frame represents: a noncoverage error.

One of the components of coverage error that results from a flawed sample frame that excludes a certain percentage of the population is noncoverage.

Sampling errors need to be controlled and reduced to a level at which their presence does not defeat or obliterate the usefulness of the final sample results.

The difference between the observed values of a variable and the long-run average of the observed values in repetitions of the measurement is the sampling error.

Noncoverage, another word for these frames, inadequate coverage is also known as undercoverage.

The relation ⊂ (subset) can be considered as a binary relation between sets, and it is a partial order on the power set P(S) of an arbitrary nonempty set S. However, it is not a total order.

A partial order is a binary relation that satisfies three properties: reflexivity, antisymmetry, and transitivity. Let's analyze whether ⊂ satisfies these properties for the power set P(S).

Reflexivity: For any set A, A is a subset of itself (A⊂A) holds true. Therefore, ⊂ is reflexive.

Antisymmetry: If A⊂B and B⊂A, then A and B must be equal sets. In other words, if two sets are subsets of each other, they must be the same set. This property is satisfied, and ⊂ is antisymmetric.

Transitivity: If A⊂B and B⊂C, then A⊂C. If one set is a subset of another set, and the other set is a subset of a third set, then the first set is also a subset of the third set. This property is satisfied, and ⊂ is transitive.

Therefore, ⊂ satisfies the properties of reflexivity, antisymmetry, and transitivity, making it a partial order on P(S).However, ⊂ is not a total order because it does not satisfy the total ordering property. In a total order, for any two distinct elements, one must be greater than or equal to the other. In the case of ⊂, there are sets A and B that are not subsets of each other (neither A⊂B nor B⊂A). Therefore, it is not a total order.

Charles has 10 apps on his phone, which can be found by subtracting 8 from both sides of the equation n + 8 = 18, resulting in n = 10.

The equation n + 8 = 18 represents the relationship between the number of apps Ross has on his phone and the number of apps Charles has on his phone. According to the equation, Ross has 18 apps on his phone and Charles has n apps on his phone, where n is a unknown quantity. The equation also states that Charles has 8 fewer apps than Ross, which is why 8 is added to n.

To find the value of n, we can subtract 8 from both sides of the equation. This isolates n on one side of the equation and gives us:

n = 18 - 8 = 10

So the value of n that balances the equation is 10, which means Charles has 10 apps on his phone.

The equation n + 8 = 18 represents the difference in the number of apps between Ross and Charles. Charles has n apps, while Ross has 8 more apps, which is why 8 is added to n in the equation. To find the value of n, we subtract 8 from both sides of the equation, which results in n = 10. This means that Charles has 10 apps on his phone.

It's important to understand that the equation represents a mathematical relationship between two quantities, in this case the number of apps Ross and Charles have on their phones. By solving the equation, we are able to determine the value of n, which is the unknown quantity in the equation.

the distinct equivalence classes [0], [1], [2], and [3] form a partition of ℤ.

What is Equivalence relation?

An equivalence relation is a relation between elements of a set that satisfies three properties: reflexivity, symmetry, and transitivity.

a) To prove that R is an equivalence relation, we need to show that it satisfies three properties: reflexivity, symmetry, and transitivity.

Reflexivity: For any integer m, we need to show that m R m, i.e., 4 |\((m^2 - m^2).\) Since the difference of squares is 0, which is divisible by 4, the relation is reflexive.

Symmetry: For any integers m and n, if m R n, then we need to show that n R m. If 4 | \((m^2 - n^2)\), then \((m^2 - n^2)\) is divisible by 4. Taking the negative of both sides, we have\((-n^2 + m^2) = (m^2 - n^2)\), which is also divisible by 4. Therefore, n R m, and the relation is symmetric.

Transitivity: For any integers m, n, and p, if m R n and n R p, then we need to show that m R p. Suppose 4 |\((m^2 - n^2)\)and 4 \(| (n^2 - p^2)\). This means \((m^2 - n^2) and (n^2 - p^2)\)are both divisible by 4. Adding these two divisibility statements, we get (m^2 - p^2) is also divisible by 4, which implies m R p. Hence, the relation is transitive.

Since the relation R satisfies reflexivity, symmetry, and transitivity, it is an equivalence relation.

b) The distinct equivalence classes of the relation R can be described by the set of all integers that are congruent modulo 4. In other words, each equivalence class contains integers that have the same remainder when divided by 4.

The distinct equivalence classes can be denoted as follows:

[0] = {..., -8, -4, 0, 4, 8, ...}

[1] = {..., -7, -3, 1, 5, 9, ...}

[2] = {..., -6, -2, 2, 6, 10, ...}

[3] = {..., -5, -1, 3, 7, 11, ...}

Each equivalence class consists of integers that satisfy the condition 4 | (m^2 - n^2), and within each class, any two integers have their squares yielding the same remainder when divided by 4.

c) The distinct equivalence classes [0], [1], [2], and [3] form a partition of ℤ. A partition of a set is a collection of non-empty, pairwise disjoint subsets whose union is the entire set.

In this case, the equivalence classes [0], [1], [2], and [3] are non-empty and pairwise disjoint because no integer can simultaneously belong to two different equivalence classes. Also, the union of all the equivalence classes covers the entire set of integers, as each integer belongs to exactly one of the equivalence classes.

Therefore, the distinct equivalence classes [0], [1], [2], and [3] form a partition of ℤ.

The circumference of the circle with a radius of 6 feet would be approximately 37.7 feet.

The circumference of a circle is the distance around the outer edge of the circle. It is the perimeter of the circle, which is the total length of the boundary that encloses the area of the circle.

The formula for the circumference of a circle is

C = 2πr

Where C is the circumference, r is the radius, and π is approximately 3.14.

If a circle has a radius of 3 feet, the circumference would be

In conclusion, Ann's preferences are likely to be rational, weakly.

In order to determine if Ann's preferences have certain properties, we need to first understand what those properties mean in terms of preferences.

i. Rational:

Rationality is the property of preferences that requires them to be transitive. In other words, if Ann prefers A to B, and B to C, then she must prefer A to C. This is a reasonable assumption for any rational person making choices.

ii. Weakly Monotone:

Weak monotonicity is the property of preferences that requires them to be non-decreasing. In other words, if Ann prefers A to B, then she must prefer any combination of A and B where there is more of A and less of B. For example, if she prefers a bowl of Laksa with 1 chicken breast and 1 fish fillet to a bowl with 1 chicken breast and 1 tofu slice, then she should also prefer a bowl with 2 chicken breasts and 1 fish fillet to a bowl with 1 chicken breast and 1 fish fillet.

iii. Strongly Monotone:

Strong monotonicity is a stronger version of weak monotonicity that requires preferences to be strictly increasing. In other words, if Ann prefers A to B, then she must strictly prefer any combination of A and B where there is more of A and less of B. For example, if she prefers a bowl of Laksa with 1 chicken breast and 1 fish fillet to a bowl with 1 chicken breast and 1 tofu slice, then she must strictly prefer a bowl with 2 chicken breasts and 1 fish fillet to a bowl with 1 chicken breast and 1 fish fillet.

iv. Locally Non-satiated:

Local nonsatiation is the property of preferences that requires them to never be satisfied with any amount of a good. In other words, if Ann prefers A to B, then she must always prefer a little bit more of A to the same amount of B. This is a reasonable assumption for any person making choices, since there is always some amount of a good that would be preferred to the current amount.

a) Now let's consider each property in turn and determine whether Ann's preferences have that property or not.

i. Rational:

Ann's preferences are assumed to be rational, since rationality is a basic requirement for any preferences.

ii. Weakly Monotone:

Ann's preferences for a range of proteins, green vegetables, and noodles in her Laksa are likely to be weakly monotone, since it is reasonable to assume that if she prefers some amount of a good to another, she would prefer any combination of the two where there is more of the preferred good.

iii. Strongly Monotone:

Ann's preferences are not likely to be strongly monotone, since it is possible that she may have some preferences for specific combinations of goods that are not strictly increasing or decreasing. For example, she may prefer a bowl of Laksa with 1 chicken breast and 1 fish fillet to a bowl with 2 chicken breasts and no fish fillet.

iv. Locally Non-satiated:

Ann's preferences are likely to be locally non-satiated, since it is reasonable to assume that she would always prefer a little bit more of a good to the same amount of that good. For example, if she likes a bowl of Laksa with 1 chicken breast, 1 fish fillet, and 1 tofu slice, she would likely prefer a bowl with 1.1 chicken breasts, 1.1 fish fillets, and 1.1 tofu slices to the same bowl with 1 chicken breast, 1 fish fillet, and 1 tofu slice.

False. The intercepted arc is actually twice the measure of the inscribed angle only if the inscribed angle is an angle at the center. If the inscribed angle is not at the center, the intercepted arc will have a different measure.

So, in general, the relationship between the measure of the intercepted arc and the inscribed angle it was created from depends on the location of the inscribed angle in the circle. This is a long answer, but it provides a detailed explanation of the relationship between the intercepted arc and the inscribed angle in different scenarios.

AN intercepted arc is twice the measure of the inscribed angle it was created from.
In a circle, when an inscribed angle is formed by two chords, it intercepts an arc on the circle. According to the Inscribed Angle Theorem, the measure of the inscribed angle is half the measure of the intercepted arc. Therefore, the intercepted arc is indeed twice the measure of the inscribed angle.
