Answer:

4 : 7

Step-by-step explanation:

First, you can start by moving all the terms to one side:

14x^2 + 6xy - 8y^2 = 0

Now we can start to factor this equation in order to find the ratio. We can start by factoring out the GCF, which is 2:

2(7x^2 + 3xy - 4y^2) = 0

In order to factor this equation we multiply the coefficients in front of the x^2 and y^2 term to get: 7 * -4 or -28. We are looking for numbers that have a product of -28 and a sum of 3(as the coefficient of the xy term). These two numbers are 7 and -4. We can rewrite the equation as:

2(7x^2 + 7xy - 4xy - 4y^2) = 0

Now, we can start to factor by grouping:

2( 7x[x + y] - 4y[x + y] ) = 0

And we can factor out [x + y]:

2(x + y)(7x - 4y) = 0

So, we can use the zero product property to get two equations:

x + y = 0

and

7x - 4y = 0

You get:

x =  -y

and

7x = 4y

We can get cancel out the first solution because both x and y have to be positive. Rearranging the second equation we can get x : y = 4 : 7

Answer:

The p-value of the test is 0.053, which is more than the standard significance level of 0.05, and thus it cannot be concluded that the mean monthly rent in the city is less than $1000.

Step-by-step explanation:

A housing official in a certain city claims that the mean monthly rent for apartments in the city is less than $1000.

At the null hypothesis, we test if the mean is of at least $1000, that is:

\(H_0: \mu \geq 1000\)

At the alternative hypothesis, we test if the mean is less than $1000, that is:

\(H_1: \mu < 1000\)

The test statistic is:

We have the standard deviation for the sample, so the t-distribution is used.

\(t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}\)

In which X is the sample mean, \(\mu\) is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.

1000 is tested at the null hypothesis:

This means that \(\mu = 1000\)

To verify this claim, a simple random sample of 47 renters in the city was taken, and the mean rent paid was $941 with a standard deviation of $245.

This means that \(n = 47, X = 941, s = 245\)

Value of the test statistic:

\(t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}\)

\(t = \frac{941 - 1000}{\frac{245}{\sqrt{47}}}\)

\(t = -1.65\)

P-value of the test and decision:

The p-value of the test is found using a left-tailed test(test if the mean is less than a value), with t = -1.65 and 47 - 1 = 46 df.

Using a t-distribution calculator, the p-value is of 0.053.

The p-value of the test is 0.053, which is more than the standard significance level of 0.05, and thus it cannot be concluded that the mean monthly rent in the city is less than $1000.

The volume of the pyramid, to the nearest cubic foot, is approximately 5 ft^3. The correct option is A.

To find the volume of the solid oblique pyramid, we need to know the formula for the volume of a pyramid. The volume of a pyramid is given by the formula V = (1/3) * A * h, where A is the base area and h is the height of the pyramid.

In this case, the base is a regular pentagon with an edge length of 2.16 ft. The area of a regular pentagon can be calculated using the formula A = (1/4) * √(5 * (5 + 2√5)) * a^2, where a is the edge length. Substituting the given value, we find that the base area is 8 ft^2.

To find the height of the pyramid, we can construct a right triangle within the pyramid. The height of the pyramid corresponds to the height of this triangle.

The angle ACB is given as 30°, and since the triangle is right-angled, the angle opposite to the height is 90° - 30° = 60°. Therefore, we have a right triangle with one angle measuring 60°, and the opposite side is the height of the pyramid.

Now, we can use trigonometry to find the height. Since we know the length of the base and the angle opposite the height, we can use the tangent function. Tan(60°) = height / (2.16 / 2). Solving for height, we find that the height is approximately 1.98 ft.

Substituting the values into the formula for the volume, we have V = (1/3) * 8 * 1.98 ≈ 5.28 ft^3.

It would cost approximately $52.18 to drive from Statesville, NC to Washington, DC with a car that gets 29 miles per gallon on the interstate, considering a gas cost of $3.89 per gallon.

To calculate the time it would take to drive from Statesville, NC to Washington, DC, we can divide the distance of 389 miles by the average speed of 65 mph.

Time = Distance / Speed

Time = 389 miles / 65 mph

Time ≈ 5.98 hours

Therefore, it would take approximately 5.98 hours to drive from Statesville, NC to Washington, DC on interstates with an average speed of 65 mph.

To calculate the cost of driving to Washington, DC, we need to know the number of gallons of gas required for the trip. We can find this by dividing the distance by the car's mileage, which is 29 miles per gallon.

Number of gallons = Distance / Mileage

Number of gallons = 389 miles / 29 miles per gallon

Number of gallons ≈ 13.41 gallons

The cost of gas can be calculated by multiplying the number of gallons by the cost per gallon, which is $3.89.

Cost = Number of gallons * Cost per gallon

Cost ≈ 13.41 gallons * $3.89/gallon

Cost ≈ $52.18

Therefore, it would cost approximately $52.18 to drive from Statesville, NC to Washington, DC with a car that gets 29 miles per gallon on the interstate, considering a gas cost of $3.89 per gallon.

A relation from A to B is a function if it satisfies two properties:

Suppose we have two sets A and B and we have a relation that maps elements of A to elements of B. A relation from A to B is defined as a function if every elements of A is related to exactly one element of B.

Let (x,y) is a pair of input and output. If (x,y) is related by a function f, we can denote  (x,y) ∈ F

We can write the first condition as:

Since x is mapped to the exactly one output, then if both y and z are elements of B and (x,y) and (a,z) are in F, then y must be equal to z. Hence, the second condition is:

Given:

Vertices of a parallelogram ABCD are A(7,-4), B(-1,-4), C(-1,-12), D(7, -12).

To find:

Whether the parallelogram ABCD is a rhombus, rectangle or square.

Solution:

Distance formula:

\(D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

Using distance formula, we get

\(AB=\sqrt{(-4-(-4))^2+(-1-7)^2}\)

\(AB=\sqrt{(-4+4)^2+(-8)^2}\)

\(AB=\sqrt{0+64}\)

\(AB=8\)

Similarly,

\(BC=\sqrt{(-1-(-1))^2+(12-(-4))^2}=8\)

\(CD=\sqrt{(7-(-1))^2+(-12-(-12))^2}=8\)

\(AD=\sqrt{(7-7)^2+(-12-(-4))^2}=8\)

All sides of parallelogram are equal.

\(AC=\sqrt{(-1-7)^2+(-12-(-4))^2}=8\sqrt{2}\)

\(BD=\sqrt{(7-(-1))^2+(-12-(-4))^2}=8\sqrt{2}\)

Both diagonals are equal.

Since, all sides are equal and both diagonals are equal, therefore, the parallelogram ABCD is a square.

We know that, a square is special case of rectangles and rhombus.

So, parallelogram ABCD is a rhombus, rectangle or square. Therefore, the correct option is c.

The equation for the line passing through the three points is y = (5/4)x.

What is equation ?

An equation is a mathematical statement that shows that two expressions are equal. It contains an equals sign (=) between two expressions.

For example, the equation 2 + 3 = 5 shows that the expression 2 + 3 is equal to the expression 5. In this equation, the expressions on both sides of the equals sign have the same value.

To find the equation for the line passing through three points (0, 0), (4, 5), and (8, 10), we can use the point-slope form of a linear equation.

The point-slope form of a linear equation is:

y - y1 = m(x - x1)

where m is the slope of the line, and (x1, y1) is a point on the line.

To find the slope of the line passing through the three points, we can use the formula:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are any two points on the line.

Using the points (0, 0) and (4, 5) to calculate the slope, we get:

slope = (5 - 0) / (4 - 0) = 5/4

Using the points (4, 5) and (8, 10) to calculate the slope, we get:

slope = (10 - 5) / (8 - 4) = 5/4

Since we get the same slope using either pair of points, we can be confident that these three points are collinear, and lie on the same line.

Now, let's use the point-slope form to write the equation of the line using one of the points, say (0, 0). Substituting the slope and the point into the equation, we get:

y - 0 = (5/4)(x - 0)

Simplifying, we get:

y = (5/4)x

Therefore,  the equation for the line passing through the three points is y = (5/4)x.
