The conclusion "(x)(A(x) ∨ B(x))" is false since there exist elements (e.g., 1) that satisfy B(x) but not A(x).

To show that the argument is invalid using the model universe method, we need to find a counterexample where the premises are true, but the conclusion is false.

Let's consider the following interpretation:

Domain of discourse: {1, 2}

A(x): x is even

B(x): x is odd

Under this interpretation, the premises "(x)(A(x) ∧ B(x))" and "(∃x)A(x)" are true because all elements in the domain satisfy A(x) ∧ B(x), and there exists at least one element (e.g., 2) that satisfies A(x).

However, the conclusion "(x)(A(x) ∨ B(x))" is false since there exist elements (e.g., 1) that satisfy B(x) but not A(x).

In this counterexample, the premises are true, but the conclusion is false, demonstrating that the argument is invalid using the model universe method.

If there are N persons and N-1 options for the number of people with whom every person can shake hands, at least two people have shaken hands with an equal number of people.

A pigeon hole principle would be a counting argument that states "if you have n items to place into m n boxes, then there are at least two items in a single boxes."

Now, according to the question;

There are N persons at a party, some of whom have shaken hands and others who have not. When two people shake hands, it counts to both of them shaking hands with one person.

As a result, it is impossible to tell who initiated the greeting. Then there's the following proposal:

It is said that at least two individuals have shaken hands the same amount of individuals.

Thus,

Although you can shake hands to yourself, an individual can shake hands had between 0 and N-1 persons. That is N different options. If a person had shaken hands to everyone else, then no one has not touched hands with anyone. And the opposite is true.

As a result, the possibilities 0 and N-1 are mutually exclusive. So we're down to N-1 people with whom each individual can shake hands.

The largest taco contained approximately 1 kg of onion for every 6. 6 kg grilled teak. then Amount of grilled steak used: 6.6 (79.17) = 538.356 kg

What is a unit amount in math?

When a price is expressed as a quantity of 1, such as $25 per ticket or $0.89 per can, it is called a unit price. If you have a non-unit price, such as $5.50 for 5 pounds of potatoes, and want to find the unit price, divide the terms of the ratio

1 k + 6.6 k = 617.3

Where “k” is a constant value, a multiplier.

Solving for k:

7.8 k = 617.3

k = 617.3 /7.8  

k= 79.17

So:

Amount of onion used:

The recurrence relation for the number of ways to form postage of n cents with 4-cent, 6-cent, and 10-cent stamps, with order mattering, is P(n) = P(n-4) + P(n-6) + P(n-10), with initial conditions P(0) = 1 and P(n) = 0 for n < 0.

To form postage of n cents, we can use either a 4-cent stamp, a 6-cent stamp, or a 10-cent stamp.

Therefore, the number of ways to form postage of n cents can be calculated by considering the number of ways to form postage of (n-4) cents, (n-6) cents, and (n-10) cents.

Let P(n) denote the number of ways to form postage of n cents with these stamps.

Then we have:

P(n) = P(n-4) + P(n-6) + P(n-10)

This is a recurrence relation for P(n).

The initial conditions for this recurrence relation are:

P(0) = 1 (There is one way to form postage of 0 cents, by using no stamps.)

P(n) = 0 for n < 0 (There are no ways to form negative postage.)

We can also find P(4), P(6), and P(10) directly:

P(4) = 1 (We can use one 4-cent stamp.)

P(6) = 2 (We can use one 6-cent stamp, or two 4-cent stamps.)

P(10) = 4 (We can use one 10-cent stamp, or one 6-cent stamp and one 4-cent stamp, or two 4-cent stamps and one 2-cent stamp, or four 2-cent stamps.)

Using these initial conditions and the recurrence relation, we can calculate P(n) for any positive integer n.

The salary of a single teacher falls into the 90th percentile at $54,912.

The z-score of a measure X in a collection with mean and standard deviation is given by:

z = (x - μ)/σ

In which,

μ is mean = $48,000

σ is standard deviation = $5,400.

This issue involves that:

Find the teacher's compensation at the 90th percentile.

When Z does indeed have a p-value of 0.9, that's the value of X. So when Z = 1.28, it is X.

1.28 = (x - 48,000)/5,400

x = 48,000 - 1.28 x 54,00

x = 54,912.

Therefore, the value of f at the point (1,-2) to the surface z = 4x³y² + 2y is 12.

Given a surface: z = 4x³y² + 2y.

The function f is defined as follows: f(x, y) = 4x³y² + 2y.

(c) Compute f. (1,-2) to the surface z = 4x³y² + 2y.

Given, the point (1, -2).

To compute f, we need to find the value of z for x = 1 and y = -2

Answer:

b=56°

Step-by-step explanation:

When given the sets a = {1, 2, 3, 4, 5} and b = {0, 3, 6}, the operations yield the following results: a) a∪b = {0, 1, 2, 3, 4, 5, 6}, b) a∩b = {3}, c) a−b = {1, 2, 4, 5}, and d) b−a = {0, 6}.

To explain further, the union of sets a and b (a∪b) includes all the elements from both sets without repetition. In this case, a∪b = {0, 1, 2, 3, 4, 5, 6} because it contains all the elements from sets a and b.

The intersection of sets a and b (a∩b) refers to the common elements present in both sets. In this case, a∩b = {3} since 3 is the only element that appears in both sets a and b.

The set difference a−b consists of elements that are in set a but not in set b. Here, a−b = {1, 2, 4, 5} because these elements are present in set a but not in set b.

Finally, the set difference b−a represents elements that are in set b but not in set a. In this case, b−a = {0, 6} because these elements are present in set b but not in set a.

The formula to calculate the value of a CD after a specific duration at a specific interest rate compounded annually is given by:

A = P(1 + r/n)^(nt)

where P is the principal,

r is the annual interest rate,

n is the number of times compounded per year,

t is the number of years, and

A is the value of the CD at maturity.

Here, we need to calculate the value of a $1,000 initial investment in each bank's CD at maturity.

Hi

first thing to do is to count how many marbles you have

so :  5 red, 4 green, 3 blue  =  5+4+3 = 12  

probability  of  green :    4/12

                         blue   :     3/12  

Probability of  either  green or blue  :  4/12 +3/12 = 7/12  

The probability that it is either a green marble or a blue marble is : P(A or B) = 7/12.

Given is that an urn contains five red marbles, four green marbles, and three blue marbles

We can write that the probability that it is either a green marble or a blue marble is -

P(A or B) = P(A) + P(B)

P(A or B) = (4/12) + (3/12)

P(A or B) = 1/3 + 1/4

P(A or B) = (4 + 3)/12

P(A or B) = 7/12

Step-by-step explanation:

If the graph intersects the x-axis, then there is an x-intercept at that point. So, we know that 3 and 9 are the x-intercepts of the parabola.

Parabolas can only have 0, 1, or 2, x intercepts. The x coordinate of the vertex will be the average of the x coordinates of the x-intercepts, since the vertex will be in the middle of the 2 x intercept points.

Take the average of 3 and 9:

(3 + 9) / 2
