No, it is not possible to create a regular tessellation with a regular heptagon. A regular tessellation, also known as a tiling, is a repeating pattern of identical regular polygonal shapes that cover a plane without any gaps or overlaps. The only regular polygonal shapes that can be used to form a regular tessellation are the equilateral triangle, square, and hexagon. These shapes have interior angles that are multiples of 60 degrees, which allows them to fit together seamlessly to form a repeating pattern. The interior angle of a regular heptagon is roughly 128.5714 degrees, which does not divide evenly into 360 degrees, so it cannot be used to form a regular tessellation.

Answer: To find the selling price of the karaoke machine with a 49.5% markup, you need to first calculate the amount of the markup. You can do this by multiplying the cost of the machine (52.75) by the markup rate (49.5%) expressed as a decimal:

52.75 * 0.495 = 26.067375

Next, add this markup amount to the cost of the machine:

52.75 + 26.067375 = 78.817375

So, the selling price of the karaoke machine with a 49.5% markup would be $78.82.

A: The correct statement is c. Statistics are used to estimate parameters.

Statistics is the science of collecting and analyzing data to gain insight into a population of interest. It involves the collection, organization, analysis, interpretation, and presentation of data. The goal of using statistics is to draw conclusions about a population of interest and to estimate parameters of the population.

A parameter is a numerical value that is used to describe a population. For example, the mean of a population is a parameter. Statistics are used to estimate parameters of a population from a sample of the population. This process is called estimation. A statistic is a numerical value that is used to describe a sample.

For example, the sample mean is a statistic that is used to estimate the population mean. Estimation is done using the formula for a sample statistic, which is given by:

Estimate= (Statistic) / (Sample Size)

Here, the statistic is the sample mean, and the sample size is the number of observations in the sample. For example, if the sample mean is 10 and the sample size is 5, then the estimate of the population mean is 2 (10/5).

Statistics can also be used to construct confidence intervals to describe population parameters, such as means and proportions. A confidence interval is an interval of values around a sample statistic, such as a mean or a proportion, that is expected to contain the population parameter with a certain level of confidence.

In conclusion, statistics are used to estimate parameters of a population from a sample of the population. Estimation is done using the formula for a sample statistic, and confidence intervals can be used to describe population parameters.

Answer:

Step-by-step explanation:

This question is about to determine the conditional statement,  proposition and either that is true or false.

The explanation of each part in this question is given below:

a) The given proposition can be written as the conjunction of two conditional statements as follows:

If a = 2 (mod 8), then [tex](a^2 + 4a) = 4 (mod 8)[/tex].

If [tex](a^2 + 4a) = 4 (mod 8)[/tex], then a = 2 (mod 8).

b) To prove the first conditional statement, assume a = 2 (mod 8). Then, there exists an integer k such that a = 8k + 2. Substituting this value of a into [tex](a^2 + 4a)[/tex], we get:

[tex]a^2 + 4a = (8k + 2)^2 + 4(8k + 2) = 64k^2 + 36k + 8[/tex]

Reducing this expression modulo 8, we get:

a^2 + 4a ≡ 64k^2 + 36k + 8 ≡ 0 + 4k + 0 ≡ 4 (mod 8)

Therefore, we have shown that if a = 2 (mod 8), then (a^2 + 4a) = 4 (mod 8).

To prove the second conditional statement, assume (a^2 + 4a) = 4 (mod 8). Then, there exists an integer k such that (a^2 + 4a) = 8k + 4. Substituting this value of (a^2 + 4a) into the equation a^2 + 4a - 8k = 0, we can use the quadratic formula to solve for a:

a = (-4 ± √(16 + 32k))/2 = -2 ± √(4 + 8k)

Since a is an integer, it follows that √(4 + 8k) must be an integer as well. This implies that 4 + 8k is a perfect square. The only perfect squares that are congruent to 4 (mod 8) are those of the form 8m + 4 for some integer m. Therefore, we have:

4 + 8k = 8m + 4

k = m

Substituting k = m back into the expression for a, we get:

a = -2 + √(4 + 8k) = -2 + √(8m + 4) = -2 + 2√(2m + 1)

Since a is an integer, it follows that √(2m + 1) must be an integer as well. This implies that 2m + 1 is a perfect square. The only perfect squares that are congruent to 1 (mod 8) are those of the form 8n + 1 for some integer n. Therefore, we have:

2m + 1 = 8n + 1

m = 4n

Substituting m = 4n back into the expression for a, we get:

a = -2 + 2√(2m + 1) = -2 + 2√(8n + 1) = 2(√(2n + 1) - 1)

Therefore, we have shown that if (a^2 + 4a) = 4 (mod 8), then a = 2 (mod 8).

Since both conditional statements have been proven, the given proposition is true.

(c) The given proposition is true, as shown in the proofs of the two conditional statements in part (b).

We can use the formula speed = distance / time to calculate the speed of the plane.

The total distance traveled by the plane is 3,000 + 600 = 3,600 miles.

The total time taken by the plane is 2 hours 30 minutes, which is equivalent to 2.5 hours.

Therefore, the speed of the plane is:

speed = distance / time

     = 3,600 / 2.5

     = 1,440 miles per hour

So the answer is (A) 1440mph

Susan could save 10.4 minutes getting to class each morning if she were to ride the bike.

As per the data given:

The distance is given between the school and the apartment = 1.3 miles

Susan's walking speed = 3 miles/hr

Now we know that speed = distance ÷ time

Putting values in the above formulae, we get the time for walking situation

3 miles/hr = 1.3 ÷ time

Time = 1.3 ÷ 3 miles

Time = (13 ÷ 30 )hr

= (13 ÷ 30) × 60 minutes

= 13 × 2

= 26 minutes

The time taken when she is walking is 26 minutes.

Here we have to determine how many minutes could Susan save getting to class each morning if she were to ride the bike.

Now if she uses a bike, the speed is 5 miles/hr

Again applying same formulae speed = distance ÷ time

5 miles/hr= 1.3 ÷ time

Time= 1.3 ÷  5 miles

= (13 ÷ 50)hr

= (13 ÷ 50) × 60 minutes

= 15.6 minutes

Time taken by bike is 15.6 minutes

Total time saved = time taken when walking - time taken using the bike

= 26 - 15.6

= 10.4 minutes

Hence, Susan could save 10.4 minutes if she uses a bike.

The limit of the difference quotient must not exist at any location z0 in the complex plane in order to demonstrate that f(z) = z is nowhere differentiable.

For f(z), the difference ratio is as follows:

[f(z Plus h) - f(z)] / h = [(z + h) - z] / h = h / h = 1

As h gets closer to 0, we take the maximum and obtain:

lim h0 [z + h - z] / = lim h 0 h / h = 1

This limit is constant at 1 and is unaffected by the number of z. The limit of the difference quotient must not exist at any location z0 in the complex plane in order to demonstrate that f(z) = z is nowhere differentiable.

Out of a population of 100,000, the number of people who read at least two newspapers is = 33,000.

Let's approach this problem using the inclusion-exclusion principle.

First, we can add up the proportions of people who read each paper to get:

P(I) + P(II) + P(III) = 10% + 30% + 5% = 45%

However, this includes the people who read two or more papers multiple times, so we need to subtract those out. We can calculate these as follows:

P(I&II) + P(I&III) + P(II&III) = 8% + 2% + 4% = 14%

2P(I&II&III) = 2%

Using the inclusion-exclusion principle, we can now find the proportion of people who read at least two papers:

P(at least 2 papers) = P(I) + P(II) + P(III) - (P(I&II) + P(I&III) + P(II&III)) + 2P(I&II&III)

Plugging in the values, we get:

P(at least 2 papers) = 45% - 14% + 2% = 33%

So, the number of people who read at least two newspapers is:

The integral that would give the volume V generated by rotating the region bounded by the given curves about the y-axis is V = ∫[from x=0 to x=6] π[(13 - x²/3)² - 13²]dx

To find the volume of a rotational solid, we can use the method of disks/washers, which involves slicing the solid into thin disks or washers, calculating the volume of each slice, and then adding them up using integration.

To use the method of disks/washers, we need to first determine the radius of each disk or washer. Since we're rotating the region around a horizontal line, the radius will be the distance from each point on the curve to the line of rotation, which in this case is y = 16. To find this distance, we subtract 16 from the y-coordinate of each point on the curve.

The outer radius is the distance from the point on the curve y = x^2/3 + 3 to the line y = 16, which is

=>  r = 16 - (x²/3 + 3) = 13 - x²/3.

The inner radius is the distance from the point on the curve y = 3 to the line y = 16, which is

=> r = 16 - 3 = 13.

Next, we need to express the volume of each disk or washer in terms of these radii.  This gives us the following formula for the volume of each slice:

dV = π[(13 - x²/3)² - 13²]dx

Finally, we can find the total volume of the solid by integrating over the range of x values that define the region we're rotating:

V = ∫[from x=0 to x=6] π[(13 - x²/3)² - 13²]dx

Evaluating this integral will give us the volume of the solid created by rotating the region between y = x²/3 + 3  and y = 3 about the line y = 16.

Comparing this to the volume of the cube when the side length is 3 cm, which is 27 cm^3, we can see that the volume of the cube is greater than the volume of the cylinder.

Step-by-step explanation:

I'm sorry, but I cannot see the graph you are referring to. However, I can still answer some of your questions based on the information provided.

When the diameter of the cylinder is 2 cm, the radius is equal to half the diameter, which is 1 cm.

To express the volume of a cube of side length s as an equation, we use the formula for the volume of a cube:

Volume of cube = s^3

Making a table for the volume of the cube at different side lengths, we get:

Side Length (cm) Volume (cm^3)

        0                                    0

        1                                     1

        2                                     8

        3                                     27

To compare the volume of the cube when the side length is 3 cm and the volume of the cylinder when the diameter is 3 cm, we need to find the radius of the cylinder first.

When the diameter is 3 cm, the radius is half the diameter, which is 1.5 cm. The height of the cylinder is also equal to the radius, so the volume of the cylinder can be found using the formula:

Volume of cylinder = πr^2h

Substituting r = 1.5 cm and h = 1.5 cm, we get:

Volume of cylinder = π(1.5)^2(1.5) ≈ 10.602 cm^3

Comparing this to the volume of the cube when the side length is 3 cm, which is 27 cm^3, we can see that the volume of the cube is greater than the volume of the cylinder.

The missing angles in triangle RST and LMN are 121° and 15° respectively.

When two straight lines or rays intersect at a single endpoint, an angle is created.

The vertex of an angle is the location where two points come together.

The Latin word "angulus," which means "corner," is where the term "angle" originates.

Angle position describes how a line interacts with another line or plane. The amount of rotation of the body relative to the reference position is used to calculate the angle of position.

Theta (), the sign used to represent the angular position, can represent the angle in degrees (°), radians (rads), or revolutions.

So, in the triangle RST:

Missing angle:

44 + 15 + x = 180

x = 180 - 59

x = 121°

In triangle LMN:

121 + 44 + x = 180

x = 180 - 165

x = 15°

Therefore, the missing angles in triangle RST and LMN are 121° and 15° respectively.

P(system functions on a non-rainy day) = P(X ≥ 4), where X ~ Binomial(n=6, p=0.9)

Using a calculator or statistical software, we find:

P(system functions on a non-rainy day) = 0.9970

(c) To find the probability that the system will function tomorrow, we need to use the law of total probability. Let R be the event that it rains tomorrow and NR be the event that it doesn't rain tomorrow. Then:

P(system functions tomorrow) = P(system functions on a rainy day)P(R) + P(system functions on a non-rainy day)P(NR)

Using the probabilities from parts (a) and (b), and the fact that P(R) = 0.2 and P(NR) = 0.8, we can calculate:

P(system functions tomorrow) = (0.8482)(0.2) + (0.9970)(0.8) = 0.9746
