Answer:

there is no solution

Step-by-step explanation:

x + y = 6 → (1)

x + y = 4 → (2)

subtract (2) from (1) term by term

(x - x) + (y - y) = 6 - 4

0 + 0 = 2

0 = 2 ← false statement

this false statement indicates the equations have no solution

Answer:

No

Step-by-step explanation:

To determine if the average number of miles flown per passenger increased by one-third between 1966 and 1976, we need to compare the increase in miles flown during that period.

According to the given table:

To find the increase in miles flown, subtract the 1966 value from the 1976 value:

[tex]\begin{aligned}\sf Increase\; in\; miles\; flown &= \sf 831 \;miles - 711\; miles\\&= \sf 120\; miles\end{aligned}[/tex]

Therefore, the average number of miles flown per passenger between 1966 and 1976 increased by 120 miles.

To check if the increase is one-third of the initial value, we need to calculate one-third of the 1966 value:

[tex]\begin{aligned}\sf One\;third \;of \;711 \;miles &= \sf \dfrac{1}{3} \times 711\; miles\\\\ &= \sf \dfrac{711}{3} \; miles\\\\&=\sf 237\;miles\end{aligned}[/tex]

Since the increase in miles flown (120 miles) is not equal to one-third of the initial 1966 value (237 miles), the statement that the average number of miles flown per passenger increased by one-third between 1966 and 1976 is not true.

Answer:

a. To fill in the missing data in the table, we can use the information given in the table along with the fact that the total number of employees is 186.

For value A: Since the total number of employees with no college credit is 28, and the total number of men is 79, we can subtract the number of men with some college (C) and college graduates (15) from the total number of men to find the missing value A. So A = 79 - C - 15.

For value B: Since the total number of women is 186, we can subtract the number of women with some college (D) and college graduates (22) from the total number of women to find the missing value B. So B = 186 - D - 22.

For value C: Since the total number of employees with some college is 81, and we have already determined the values A and D, we can subtract A and D from the total number of employees with some college to find the missing value C. So C = 81 - A - D.

For value D: Similarly, we can subtract B and E from the total number of women to find the missing value D. So D = 186 - B - E.

For value E: Since the total number of college graduates is 37 (15 men + 22 women), we can subtract the number of college graduates among men (15) from the total to find the missing value E. So E = 37 - 15.

For value F: Since the total number of employees is 186, we can subtract the total number of men (79) from the total to find the missing value F. So F = 186 - 79.

b. Joint relative frequency refers to the proportion of individuals that fall into a particular combination of categories. For example, the joint relative frequency of men with no college credit is the number of men with no college credit divided by the total number of employees (28/186). These data are joint and relative because they represent the proportion of individuals in a specific category combination relative to the total population.

c. To summarize the data using conditional relative frequency, we can calculate the proportion of individuals in each category given a specific condition. For example, we can calculate the conditional relative frequency of women who are college graduates by dividing the number of women who are college graduates (22) by the total number of women (186). Similarly, we can calculate the conditional relative frequency of men with some college by dividing the number of men with some college (C) by the total number of men (79).

To summarize the data using marginal relative frequency, we can calculate the proportion of individuals in each category by dividing the number of individuals in that category by the total number of individuals. For example, we can calculate the marginal relative frequency of men by dividing the total number of men (79) by the total number of employees (186). Similarly, we can calculate the marginal relative frequency of college graduates by dividing the total number of college graduates (37) by the total number of employees (186).

d. The data in the table can be analyzed to determine if there is an association or relationship between the variables. If the values in the table change depending on the categories of the other variable, then the variables are dependent. In this case, the data is dependent because the number of individuals with certain educational levels (no college credit, some college, college graduate) varies based on their gender. For example, there are different proportions of men and women in each educational category, indicating a relationship between gender and education level.

Step-by-step explanation:

The missing values in the two-way frequency table are filled based on the given values and the composition of the table. The table represents joint relative frequency, which is the proportion of specific groups in the total population. We can summarize the data using marginal and conditional relative frequencies, and the data are considered dependent because an employee's education level depends on their gender.

To fill in the missing values of the two-way frequency table, we need to use the given numbers and the rules of the two-way frequency table. Here are the strategies used for filling in the values for A through F:

The table will also represent joint relative frequency because each cell represents the joint occurrence of two categories (gender and education level). For example, the number of male employees with no college credit (28) divided by the total number of employees (186) is a joint relative frequency.

We may summarize the table data using conditional relative frequency and marginal relative frequency. The marginal relative frequency is the total of each row or column divided by the grand total. The conditional relative frequency would be, for example, the proportion of women among those with no college credit.

The data are dependent because the education level depends on whether the employee is a man or a woman.

Answer:

[tex]\textsf{The parabola has a vertex at $\left(\:\boxed{-3}\:,\boxed{-7}\:\right)$, has a p-value of $\boxed{-1}$ and it}[/tex]

[tex]\textsf{$\boxed{\sf op\:\!ens\;to\;the\;left}$\:.}[/tex]

Step-by-step explanation:

The given directrix of the parabola is x = -2, which is a vertical line.

The directrix is perpendicular to the axis of symmetry. Therefore, this means that the parabola has a horizontal axis of symmetry.

The focus of a parabola is a fixed point located inside the curve. The x-coordinate of the given focus is x = -4. As this is to the left of the directrix, it means that the parabola opens to the left.

The standard form of a horizontal parabola is:

[tex]\boxed{(y-k)^2=4p(x-h)}[/tex]

where:

As the focus is (-4, -7), then:

[tex]\begin{aligned}(h+p, k)&=(-4,-7)\\\\\implies k&=-7\\\implies h+p&=-4\end{aligned}[/tex]

As the directrix is x = -2, then:

[tex]h - p=-2[/tex]

To find the value of h, sum the equations involved h and p to eliminate p:

[tex]\begin{array}{crcccr}&h &+& p& =& -4\\+&h& -& p& = &-2\\\cline{2-6}&2h&&& =& -6\\\cline{2-6}\\\implies &h&&&=&-3\end{array}[/tex]

To find the value of p, substitute the found value of h into one of the equations:

[tex]\begin{aligned}-3 - p&=-2\\p&=-3+2\\p&=-1\end{aligned}[/tex]    

Therefore, the values of h, k and p are:

The parabola has a vertex at (-3, -7), has a p-value of -1 and it opens to the left.

The parabola has a vertex at (-3, y), has p-value of 1 and it equation is

(x + 3)² = 4y.

To find the equation of the parabola with the given focus and directrix, we can use the standard form equation of a parabola:

(x - h)² = 4p(y - k)

where (h, k) is the vertex of the parabola and "p" is the distance from the vertex to the focus (and also from the vertex to the directrix).

Given:

Focus: (-4, -7)

Directrix: x = -2

1. Finding the vertex:

Since the directrix is a vertical line, the vertex lies on the line that is equidistant from the focus and directrix. In this case, it lies on the line x = (-4 + (-2))/2 = -3.

Therefore, the vertex of the parabola is (-3, y).

2. Finding the p-value:

The distance from the vertex to the focus (and also to the directrix) is the same. In this case, the distance is |-3 - (-4)| = 1.

Therefore, the value of "p" is 1.

3. Writing the equation of the parabola:

Using the vertex (-3, y) and the p-value of 1, we can write the equation of the parabola:

(x - h)² = 4p(y - k)

(x - (-3))² = 4(1)(y - y)

Simplifying, we get:

(x + 3)² = 4(y - y)

(x + 3)² = 4y

So, the equation of the parabola is (x + 3)² = 4y.

The vertex of the parabola is (-3, y) and the p-value is 1.

The function Sam can use to figure his total earnings for the day, based on the number of people he serves, is E(n) = 42 + 5n.

To calculate Sam's total earnings for the day, we need to consider both his hourly wages and the tips he receives based on the number of people he serves. Let's break it down step by step.

First, we know that Sam earns $7 per hour as his wage. Since he works for 6 hours, his earnings from wages alone would be $7 multiplied by 6, which equals $42.

Next, Sam also earns about $5 in tips for each person he serves. We can represent the number of people Sam serves as "n". Therefore, his total tip earnings would be $5 multiplied by "n", which gives us 5n.

To calculate Sam's total earnings for the day, we add his earnings from wages and tips together. So the function representing his total earnings, "E", can be written as:

E(n) = 7(6) + 5n

Simplifying further, we get:

E(n) = 42 + 5n

The eigenvalues of the given matrix are approximately -1.8478, 0.8478, and 2, and the corresponding eigenvectors are approximately [-0.577, -0.577, -0.577], [0.6614, -0.6614, 0], and [0.577, 0.577, 0.577].

To find the eigenvalues and eigenvectors of the given matrix:

Let A be the given matrix:

A = [[0, 1, 1],

    [1, 0, 1],

    [1, 1, 0]]

To find the eigenvalues, we need to solve the characteristic equation det(A - λI) = 0, where λ is the eigenvalue and I is the identity matrix.

The characteristic equation becomes:

det([[0-λ, 1, 1],

    [1, 0-λ, 1],

    [1, 1, 0-λ]]) = 0

Expanding the determinant, we have:

-(λ³ - 2λ - 2) = 0

Simplifying, we get:

λ³ - 2λ - 2 = 0

Now we solve this equation to find the eigenvalues:

By analyzing the equation or using numerical methods, we find that the eigenvalues are approximately:

λ₁ ≈ -1.8478

λ₂ ≈ 0.8478

λ₃ ≈ 2

To find the eigenvectors, we substitute each eigenvalue back into the equation (A - λI) * v = 0 and solve for v.

For λ₁ ≈ -1.8478:

(A - λ₁I) * v₁ = 0

Solving this equation, we find the eigenvector v₁ associated with λ₁ as:

v₁ ≈ [-0.577, -0.577, -0.577]

For λ₂ ≈ 0.8478:

(A - λ₂I) * v₂ = 0

Solving this equation, we find the eigenvector v₂ associated with λ₂ as:

v₂ ≈ [0.6614, -0.6614, 0]

For λ₃ ≈ 2:

(A - λ₃I) * v₃ = 0

Solving this equation, we find the eigenvector v₃ associated with λ₃ as:

v₃ ≈ [0.577, 0.577, 0.577]

Therefore, the eigenvalues of the given matrix are approximately -1.8478, 0.8478, and 2, and the corresponding eigenvectors are approximately [-0.577, -0.577, -0.577], [0.6614, -0.6614, 0], and [0.577, 0.577, 0.577].

Answer:

the effective tax rate for a taxable income of $175,000 is approximately 21.02%.

Step-by-step explanation:

Let's break down the income into the corresponding tax brackets:

The first $10,275 is taxed at a rate of 10%.

Tax on this portion: $10,275 * 0.10 = $1,027.50

The income between $10,276 and $41,175 is taxed at a rate of 12%.

Tax on this portion: ($41,175 - $10,276) * 0.12 = $3,710.88

The income between $41,176 and $89,075 is taxed at a rate of 22%.

Tax on this portion: ($89,075 - $41,176) * 0.22 = $10,656.98

The income between $89,076 and $170,050 is taxed at a rate of 24%.

Tax on this portion: ($170,050 - $89,076) * 0.24 = $19,862.88

The income between $170,051 and $175,000 is taxed at a rate of 32%.

Tax on this portion: ($175,000 - $170,051) * 0.32 = $1,577.44

Now, sum up all the taxes paid:

$1,027.50 + $3,710.88 + $10,656.98 + $19,862.88 + $1,577.44 = $36,836.68

The effective tax rate is calculated by dividing the total tax paid by the taxable income:

Effective tax rate = Total tax paid / Taxable income

Effective tax rate = $36,836.68 / $175,000 = 0.21024 (rounded to the nearest hundredth)

[tex]\dfrac{(x+6)^2}{25}-\dfrac{(y+8)^2}{144}=1[/tex]

Step-by-step explanation:

To write the equation of the hyperbola with foci (7, -8) and (-19, -8), and vertices (-1, -8) and (-11, -8), we first need to determine the orientation of the hyperbola.

As the y-values of the foci are the same, the foci are located horizontally from the center of the hyperbola, and therefore the hyperbola is horizontal (opening left and right).

The standard equation for a horizontal hyperbola is:

[tex]\boxed{\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1}[/tex]

where:

The center of a hyperbola is the midpoint of the vertices.

Given that the vertices are (-1, -8) and (-11, -8), we can use the midpoint formula to find the coordinates of the center:

[tex](h,k)=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)[/tex]

[tex](h, k)=\left(\dfrac{-1-11}{2},\dfrac{-8-8}{2}\right)[/tex]

[tex](h, k)=\left(-6,-8\right)[/tex]

The value of "a" is the distance between the center of the hyperbola and each vertex.  To find the value of a, calculate the distance between the x-coordinates:

[tex]a=-1-(-6)=5[/tex]

[tex]a=-6-(-11)=5[/tex]

The value of "c" is the distance between the center of the hyperbola and each focus.  Given that the foci are (7, -8) and (-19, -8), and the center is (-6, -8), to find the value of c, calculate the distance between the x-coordinates:

[tex]c = 7-(-6)=13[/tex]

[tex]c = -6-(-19)=13[/tex]

Now we have determined the values of a and c, we can use c² = a² + b² to find the value of b:

[tex]c^2 = a^2 + b^2[/tex]

[tex]13^2 = 5^2 + b^2[/tex]

[tex]169 = 25 + b^2[/tex]

[tex]b^2=144[/tex]

[tex]b=12[/tex]

Finally, substitute the found values of a, b, h and k into the standard equation of a hyperbola:

[tex]\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1[/tex]

[tex]\dfrac{(x-(-6))^2}{5^2}-\dfrac{(y-(-8))^2}{12^2}=1[/tex]

[tex]\dfrac{(x+6)^2}{25}-\dfrac{(y+8)^2}{144}=1[/tex]

Therefore, the equation of the hyperbola with foci (7, -8) and (-19, -8), and vertices (-1, -8) and (-11, -8) is:

[tex]\boxed{\dfrac{(x+6)^2}{25}-\dfrac{(y+8)^2}{144}=1}[/tex]
