Answer:

∠ AFE = 80°

Step-by-step explanation:

Since BD is a straight line , then

∠ AFB + ∠ AFE + ∠ EFD = 180°, that is

50° + ∠ AFE + 50° = 180°

100° + ∠ AFE = 180° ( subtract 100° from both sides )

The required length of the rectangle is 89 m.

Given that,
The area of a rectangular field is 6942 m. If the width of the field is 78 m, what is its length is to be determined.

Perimeter is the measure of the figure on its circumference.

The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.

The area of the rectangle = length * width
                                6942  = length * 78
                                length = 89 m

Thus, the required length of the rectangle is 89 m.

Therefore the inverse of the function is

\(y = \frac{x + 4}{3} \)

To create a square with 50px sides, we need to draw four lines that are each 50px long and perpendicular to one another.

A square is a quadrilateral (a four-sided shape) with four equal sides and four equal angles of 90 degrees each. To create a square with 50px sides, we need to follow a few steps.

Step 1: Draw a line that is 50px long using a ruler or any other measuring tool.

Step 2: At the end of the line, draw a second line that is also 50px long and perpendicular to the first line. This will form the first side of the square.

Step 3: From the end of the second line, draw a third line that is also 50px long and perpendicular to the second line. This will form the second side of the square.

Step 4: Finally, draw a fourth line that is 50px long and perpendicular to the third line, connecting back to the starting point of the first line. This will form the remaining two sides of the square.

By following these steps, you have successfully created a square with 50px sides.

In summary, a square is a four-sided shape with four equal sides and angles of 90 degrees each. The resulting shape will be a square with 50px sides.

The Average cost, after calculations, comes up to 210/x + 2.

To find the following functions such as Revenue, Cost, Profit and Average cost, we have given the equations as below:

Number of DVD's sold each day: n(x) = x

Selling price for each DVD: p(x) = 8.5 - 0.02x  Daily fixed costs: f(x) = 210  Daily variable costs: v(x) = 2x

To Find the following functions:

a. Revenue = R(x) = the product of the number of DVD's sold each day and the selling price of each DVD.

b. Cost = C(x) = the sum of the fixed costs and the variable costs.

c. Profit = P(x) = the difference between revenue and cost

d. Average cost = C (x) C¯(x) = the quotient of cost and the number of DVD's sold each day.

Number of DVD's sold each day: n(x) = x

Selling price for each DVD: p(x) = 8.5 - 0.02x  Daily fixed costs: f(x) = 210  Daily variable costs: v(x) = 2x

a. Revenue = R(x) = the product of the number of DVD's sold each day and the selling price of each DVD.R(x) = n(x) × p(x) = x × (8.5 - 0.02x) = 8.5x - 0.02x2

b. Cost = C(x) = the sum of the fixed costs and the variable costs.C(x) = f(x) + v(x) = 210 + 2x = 2x + 210

c. Profit = P(x) = the difference between revenue and cost.P(x) = R(x) - C(x) = 8.5x - 0.02x2 - (2x + 210) = -0.02x2 + 6.5x

d. Average cost = C(x)C¯(x) = the quotient of cost and the number of DVD's sold each day. C¯(x) = C(x) / x = (210 + 2x)/x = 210/x + 2

No, we cannot conclude that 90% of households have between .7 and 2.1 children based on the confidence interval alone.

Based on the confidence interval alone, we cannot come to the conclusion that 90% of households have a number of children between .7 and 2.1. A confidence interval only provides a range of values that likely contains the true population parameter (in this case, the average number of children per household) with a certain level of confidence (in this case, 90%). It does not provide information about the distribution of the variable within the population.

Step-by-step explanation:

You can find the vertices by finding the X and Y coordinates in the plane, after rotating it 180 degrees.

Answer:

x = y = 4\(\sqrt{2}\)

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos45° = \(\frac{\sqrt{2} }{2}\)  , then

cos45° = \(\frac{adjacent}{hypotenuse}\) = \(\frac{x}{8}\) ( multiply both sides by 8 )

8 × cos45° = x , then

x = 8 × \(\frac{\sqrt{2} }{2}\) = 4\(\sqrt{2}\)

The third angle in the triangle = 45° ( sum of angles in triangle )

Then the triangle is isosceles with congruent legs, thus

x = y = 4\(\sqrt{2}\)

You must count the instances of each rule and the instances of each item in each rule separately using the data in the Excel file in order to determine the support, confidence, and lift of a rule.

Open the Excel file and look for the information on the options ordered for the specific model of car. This information will probably be presented as a table or a group of columns, where each row represents a distinct order and each column a different choice.

You must count the instances of the rule's components occurring together in the data in order to calculate the support for a rule. You would need to track how frequently the fastest engine choice and the traction control option are selected together, for instance, if the rule is "If the quickest engine, then traction control." This can be accomplished by counting the number of cells in a range that satisfy a specific condition using Excel's COUNTIF function.

The confidence in a rule is calculated by dividing the total number of times the items in the premise (the "if" component of the rule) occur by the total number of times the items in the rule. The number of times the fastest engine and traction control options are selected together must be divided by the total number of times the fastest engine option is ordered, for instance, if the rule is "If the fastest engine, then traction control."

You must divide the rule's confidence by the support of the item in the rule's conclusion to determine the lift of a rule (the "then" part of the rule). You would need to divide the rule's confidence by the support for the traction control option, for instance, if the rule is "If the quickest engine, then traction control."

To calculate the support, confidence, and lift for each of the rules, you can use the Excel formulas indicated above together with any other Excel functions or tools you are familiar with.

It is crucial to keep in mind that the precise formulas and processes you will need to follow will depend on the exact data and rules you are working with, so you might need to modify the following instructions to suit your personal needs.

Answer:

x = 23

y = 119

Step-by-step explanation:

Line m is parallel to line n and the angle given as 61 and the angle that is represented with 4x - 31 are alternate angles and have equal measurement.

We can write the following equation based on this information:

4x - 31 = 61 add 31 to both sides

4x = 92 divide both sides by 4

x = 23

now onto y,

the angle represented with y and the angle that is represented with 4x - 31 are supplementary and their measures add up to 180:

4x - 31 + y = 180 replace x with 23

4*23 - 31 + y = 180

92 - 31 + y = 180 subtract like terms

61 + y = 180 subtract 61 from both sides

y = 119

The area of the triangle with the given vertices is 6.6.

The formula for finding the area of a triangle given its vertices is A = 1/2 abs(x1y2 + x2y3 + x3y1 - x2y1 - x3y2 - x1y3). To calculate the area of the given triangle, we substitute the coordinates of each vertex into the formula. First we find the three cross-products: x1y2 = 0 * 6 = 0, x2y3 = 2.8 * 6 = 16.8, and x3y1 = 5 * 0 = 0. Then, we find the two products of the y-coordinates: x2y1 = 2.8 * 0 = 0, and x3y2 = 5 * 6 = 30. Lastly, we find the product of the x-coordinates: x1y3 = 0 * 6 = 0. Adding all these up, we get 0 + 16.8 + 0 - 0 - 30 - 0 = -13.2. We then take the absolute value of the result, abs(-13.2) = 13.2. Finally, we multiply the result by 1/2 to get the area of the triangle, A = 1/2 abs(-13.2) = 1/2 * 13.2 = 6.6. Therefore, the area of the triangle with the given vertices is 6.6.

In this case, the true statement is that surface waves typically have the largest amplitude.

Explanation:

What are seismic waves?

Seismic waves are vibrations that travel through the earth's layers and carry the energy from an earthquake's release. Seismic waves are divided into two main types: body waves and surface waves.

Body waves are waves that travel through the earth's interior and have two different types: P-waves, or primary waves, and S-waves, or secondary waves.

Surface waves are the waves that travel along the earth's surface and are responsible for the most significant destruction during an earthquake. Surface waves are divided into two types: Rayleigh waves and Love waves.

Surface waves typically have the largest amplitude, which means that they are the ones that shake the most and cause the most significant destruction.

Based on the given information, the calculation of the stock's intrinsic value suggests that you would be willing to pay a certain amount for Consolidated Edison stock. The annual dividend is $3 per share, with an expected growth rate of 10% and a required rate of return of 16%.

To determine the intrinsic value of a stock using the dividend growth model, you can use the formula: Intrinsic Value = Dividend / (Required Rate of Return - Growth Rate). Applying this formula, the intrinsic value of the stock can be calculated as follows: $3 / (0.16 - 0.10) = $3 / 0.06 = $50.

Therefore, based on the given information, you would be willing to pay up to $50 for Consolidated Edison stock. It is important to note that this calculation assumes a constant growth rate and does not account for other factors that may influence the stock's value, such as market conditions, company performance, or industry trends.
