The statement ∀x∃y∃z(y 6= z → p(x, y) ∧ p(x, z)) is false.

Let's start by understanding what "p" is. "p" is a function that takes in two arguments, x and y. It tells us whether the relationship between x and y is true or false.

Now, let's look at the statement

=>∀x∃y∃z(y 6= z → p(x, y) ∧ p(x, z)).

This statement says that for every x, there exists a y and a z such that y is not equal to z and both p(x, y) and p(x, z) are true.

This statement is actually false.

Why? Imagine if p(x, y) only returned true when y was equal to x. Then, there would be no y and z such that y is not equal to z and both p(x, y) and p(x, z) are true.

Therefore, it is possible for the function "p" to return false for the statement

=> ∀x∃y∃z(y 6= z → p(x, y) ∧ p(x, z)).

It depends on the definition of the function. To determine if the statement is true or false, we need to know what the function "p" is.

Answer:

he bought 45 shrubs. Let me know if this worked for you.

Step-by-step explanation:

0.28 can be expressed as the ratio of integers 7:11.

To express 0.28 as a ratio of integers, we need to first convert the repeating decimal 0.28282828 into a fraction.
Let x = 0.28282828
Then, 100x = 28.28282828
Subtracting x from 100x, we get:
99x = 28
x = 28/99

Therefore, 0.28282828 can be expressed as the fraction 28/99.

Now, to express 0.28 as a ratio of integers, we need to simplify the fraction 28/99.

We can do this by dividing both the numerator and denominator by their greatest common factor, which is 4.
28/99 = (7*4)/(9*11) = 7/11

Therefore, 0.28 can be expressed as the ratio of integers 7:11.

In summary:
0.28 = 0.28282828 (repeating decimal)
0.28282828 = 28/99 (fraction)
28/99 can be simplified to 7/11
Therefore, 0.28 can be expressed as the ratio of integers 7:11.

Finding the sum of two complex numbers, z₁ and z₂, geometrically on the complex plane, one can follow these steps:

1. Construct z₁ and z₂ as vectors on the complex plane. Treat the complex plane as a Cartesian coordinate system, where the real part of a complex number represents the x-axis and the imaginary part represents the y-axis.

2. Draw a vector from the origin (0,0) to z₁. This vector represents z₁.

3. Draw a vector from the origin to z₂. This vector represents z₂.

4. To find z₁ + z₂, place the tail of the second vector (representing z₂) at the head of the first vector (representing z₁). The resulting vector, starting from the origin and ending at the head of the second vector, represents the sum z₁ + z₂.

5. Measure the length of the resulting vector, which represents the magnitude of z₁ + z₂. You can also find the angle between this vector and the positive real axis, which represents the argument (phase) of z₁ + z₂.

To find z₁ - z₂ geometrically, one can as well follow a similar procedure:

1. Plot z₁ and z₂ as vectors on the complex plane.

2. Draw a vector from the origin to z₁. This vector represents z₁.

3. Draw a vector from the origin to z₂. This vector represents z₂.

4. To find z₁ - z₂, place the tail of the second vector (representing z₂) at the head of the first vector (representing z₁), but in the opposite direction. The resulting vector, starting from the origin and ending at the head of the second vector, represents z₁ - z₂.

5. Measure the length of the resulting vector, which represents the magnitude of z₁ - z₂. You can also find the angle between this vector and the positive real axis, which represents the argument (phase) of z₁ - z₂.

Do not forget to consider both the magnitude and the angle when determining the geometric representation of complex number addition and subtraction on the complex plane.

A. Dawn's gross monthly pay is $4,000 ($48,000/12).

B. The month that Dawn hit her maximum taxable Social Security Income is May (5 months from January to May).

C. In February, 1978, Dawn paid $260 in Social Security Tax.

D. In May, 1978, Dawn paid $110.50 in Social Security Tax, which represented the balance.

E. In November, 1978, Dawn paid $0 in Social Security Tax because by May she had completely paid the maximum Social Security Tax of $1,150.50.

Gross earnings in 1990 = $48,000

Maximum taxable income in 1990 = $17,700

Social Security Tax Rate = 6.5%

Gross monthly pay = $4,000 ($48,000/12)

Monthly Social Security Tax = $260 ($4,000 x 6.5%)

Total Social Security Tax = $1,150.50 ($17,700 x 6.5%)

In 5 months, Dawn would have paid a total of $1,150.50 ($260 x 4 + $110.50) in Social Security Tax.

Thus, the total Social Security Tax paid by Dawn in that year was $1,150.50.

Answer:

x = 1; y = 5/4

Step-by-step explanation:

7/x - 5/y = 3

2/x + 25/(2y) = 12

The LCD of first equation is xy. Multiply both sides of the first equation by xy.

xy(7/x) - xy(5/y) = 3xy

7y - 5x = 3xy

The LCD of second equation is 2xy. Multiply both sides of the second equation by 2xy.

2xy(2/x) + 2xy(25/2y) = 24xy

4y + 25x = 24xy

7y - 5x = 3xy

4y + 25x = 24xy

Multiply the top equation by -8 and add to bottom equation.

    -56y + 40x = -24xy

(+)     4y + 25x = 24xy

---------------------------------

    -52y + 65x = 0

65x = 52y

x = 52y/65

7y - 5x = 3xy

7y - 5(52y/65) = 3(52y/65)y

455y - 260y = 156y²

156y² - 195y = 0

4y² - 5y = 0

y(4y - 5) = 0

y = 0  or  4y = 5

y = 0  or y = 5/4

7/x - 5/y = 3

y cannot equal zero.

7/x - 5/y = 3

7/x - 5/(5/4) = 3

7/x - 4 = 3

7/x = 7

x = 1

Solution: x = 1; y = 5/4

The percentage of Zachary's pay due to his deductions comprise exists 18.724%.

Zachary exists supposed to earn a paycheck of $20,160.00 but instead, he acquires a lesser amount of money due to deductions. The money he acquires after deductions exists at $16,385.31.

Money deducted = Original paycheck amount - deductions

= $20,160.00 - $16,385.31

= $3,774.69.

So Zachary obtains a deduction of $3,774.69.

To estimate the percent of deductions in terms of his pay we divide the deduction cost with the original paycheck amount and multiply it by 100 to transform it into a percentage.

Deduction % = ($3,774.69 / $20,160.00) \(*\) 100

= 0.1872366 \(*\) 100

= 18.72366%

The given statement "a structure chart should be more horizontal and less vertical because the main function should make a majority of the user- defined function calls" is FALSE because it should not necessarily be more horizontal and less vertical.

The orientation and structure of a structure chart depends on the specific requirements and characteristics of the system being modeled.

The purpose of a structure chart is to visually represent the components of a system and the relationships between them, not to follow a specific format or layout. The most important consideration when creating a structure chart is to accurately depict the system's functionality and structure in a clear and understandable way.

Therefore, the orientation of a structure chart should be chosen based on the system's needs rather than any arbitrary rules or guidelines.

The significance level of 0.10 indicates that we are willing to accept a 10% chance of making a type I error, which is rejecting the null hypothesis when it is actually true.

To determine whether there is sufficient evidence to refute the publisher's claim that 63% of their readers own a personal computer, we need to conduct a hypothesis test.

The null hypothesis (H0) is the assumption that the publisher's claim is true, meaning that 63% of their readers own a personal computer. The alternative hypothesis (Ha) is the assertion that the publisher's claim is false, meaning that less or more than 63% of their readers own a personal computer.

Using symbols, we can state the hypotheses as follows:

H0: p = 0.63 (where p is the proportion of readers who own a personal computer)

Ha: p ≠ 0.63 (the publisher's claim is false)

To test these hypotheses, we need to collect a sample of readers and determine the proportion of them who own a personal computer. We can then use a statistical test, such as a z-test or a t-test, to determine how likely it is that our sample proportion is significantly different from the claimed proportion of 63%.

The significance level of 0.10 indicates that we are willing to accept a 10% chance of making a type I error, which is rejecting the null hypothesis when it is actually true. If our statistical test results in a p-value less than or equal to 0.10, we would reject the null hypothesis and conclude that there is sufficient evidence to refute the publisher's claim. If the p-value is greater than 0.10, we would fail to reject the null hypothesis and conclude that there is not enough evidence to refute the publisher's claim.

The expected profit on the listing is $5031.96

Step-by-step explanation:

Given that:

The probability of selling the house in 6 months is p = 0.37

The probability of not selling the house = 1 - 0.37 = 0.63

Suppose Y represents the profit on the listing,

Then: the expected profit on the listing can be computed as:

E(X) = ($20283* 0.37) - ($3925*0.63)

E(X) = $7504.71 - $2472.75

E(X) = $5031.96

Thus, the expected profit on the listing is $5031.96

The expected profit on the listing is $5031.96.

Since

The probability of selling the house in 6 months is p = 0.37

The probability of not selling the house = 1 - 0.37 = 0.63

here Y means the profit on the listing,

So, the expected profit is

E(X) = ($20283* 0.37) - ($3925*0.63)

E(X) = $7504.71 - $2472.75

E(X) = $5031.96
