Answer:

D

Step-by-step explanation:

Firstly, the question is phrased very very badly as the four answers provided are coordinate points rather than how far apart the cities are in units.

To calculate the distance between two points, we have to use Pythagoras' Theorem as it's just pretty much a right-angle triangle. Please look at the (terribly drawn) image provided.

Keep in mind that these points are only roughly placed on the map.

But firstly, to use Pythagoras' Theorem (a^2 + b^2 = c^2), we must find the length of the two sides.

To find the length of the horizontal line (which from now on I'll refer to as 'a'), we must subtract the smaller x value from the larger one.

47 - 35 = 12

To find the length of the vertical line (which from now on I'll refer to as 'b'), we must subtract the smaller y value from the larger one.

122 - 78 = 44

I assume that the answer you should pick is D. (12, 44)

However, that doesn't exactly answer the question... it's worded a little weirdly.

To solve the rest of the equation, do the following:

Now that we know that the length of a = 12 and the length of b = 44, we can use Pythagoras' Theorem.

a^2 + b^2 = c^2

12^2 + 44^2 = c^2

144 + 1936 = c^2

2080 = c^2

c = \(\sqrt{2080}\)

c = 45.61

The answer is 45.61 units.

The result cos²(α) = -2 is not possible, as the square of cosine must be between 0 and 1. It appears there might be an error in the given information. Please double-check the values and try again.

Given that cos(2α) = -5 and that it terminates in quadrant I, we need to find the exact value of sin(α).

First, let's recall the Pythagorean identity: sin²(α) + cos²(α) = 1.

Since cos(2α) = -5, we need to find the value of cos(α). In order to do this, we'll use the double-angle formula for cosine: cos(2α) = 2cos²(α) - 1.

Now, we can plug in the given value of cos(2α) and solve for cos(α):
-5 = 2cos²(α) - 1
-4 = 2cos²(α)
cos²(α) = -2

One investigator takes a sample of 100 men age 18-24 in a certain town. Another takes a sample of 1,000 such men.a) The investigator who takes a sample of 1,000 men age 18-24 is more likely to get a bigger average for the heights of the men in his sample. b)The investigator who takes a sample of 100 men age 18-24 is more likely to get a bigger SD for the heights of the men in his sample.

a) The investigator who takes a sample of 1,000 men age 18-24 is more likely to get a bigger average for the heights of the men in his sample.

This is because a larger sample size tends to provide a better estimate of the population mean, and thus, the sample mean tends to be closer to the true population mean.

b) The investigator who takes a sample of 100 men age 18-24 is more likely to get a bigger SD for the heights of the men in his sample.

This is because a smaller sample size tends to provide a less accurate estimate of the population SD, and thus, the sample SD tends to be further from the true population SD.

However, if the population SD is known, then the sample size does not affect the SD of the sample mean.

Answer:

60.39 inches

Step-by-step explanation:

Given that:

A Pac-Man poster which is having three fourth of a circle and there are two sides.

Diameter of circle = 18 inches

Sides of Pac-Man poster = 9 inches

To find:

Perimeter of the Pac-Man poster.

Solution:

Perimeter of a figure is nothing but equal to the periphery i.e. the outer area of the circle/figure.

Perimeter of a circle is given by the formula:

Perimeter = \(2\pi r\)

\(r\) is the radius of the circle.

Radius is half of perimeter.

\(r=\dfrac{18}{2} = 9\ inches\)

Perimeter of the Pac-Man poster = Perimeter of \(\frac{3}{4}\) circle + 2 sides

Perimeter of the Pac-Man poster = \(\frac{3}{4}\times 2\times \pi \times 9\)  + 9+9 = 42.39+28 = 60.39 inches

An equation for the line of best fit for a men's height, y, based on her shoe size, x is; y = 0.25x + 66.6

A line of best fit can be defined as a statistical (analytical) tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any association (correlation) between a data.

In this scenario, the men's shoe size would be plotted on the x-axis of the scatter plot while her height would be plotted on the y-axis.

By critically observing the scatter plot (see attachment) which models the data, we can reasonably deduce that an equation for the line of best fit is given by:

Answer:

48.8 square inches

Step-by-step explanation:

To find the area of the triangle, we can use the formula:

Area = 1/2 * base * height

In this case, the base of the triangle is the longer side, which is 13 inches, and the height is the shorter side, which is 7.5 inches. However, we need to make sure that the angle provided is the angle between the base and the height, and not one of the other angles of the triangle.

Assuming that the angle provided is indeed the angle between the base and the height, we can proceed with the calculation:

Area = 1/2 * 13 inches * 7.5 inches

Area = 48.75 square inches

Rounded to the nearest tenth, the area of the triangle is 48.8 square inches.

The multiples of 6 from 1 to 100 are 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96.

Multiples of 6 are numbers that are obtained by multiplying 6 with a whole number. To find the multiples of 6 from 1 to 100, we need to list out all the numbers which are the result of multiplying 6 with any whole number from 1 to 16.

The first multiple of 6 is 6 (6 x 1 = 6). The second multiple of 6 is 12 (6 x 2 = 12). The third multiple of 6 is 18 (6 x 3 = 18), and so on. We can continue this pattern until we reach 16, as 6 x 16 = 96 and this is the last multiple of 6 that is less than 100.

Therefore, the multiples of 6 from 1 to 100 are 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, and 96.

The unemployment rate for 2019 and 2020 is 4.76% and 16.67% respectively. The labor force participation rates for 2019 and 2020 is 70% and 58.06% respectively. Based on these changes the economy is in the contraction phase of the business cycle.

To calculate the unemployment rates and labor force participation rates for 2019 and 2020 for the country of Manga, we will use the following equations.

1. Calculate the labor force for each year: Labor force = Employment + Unemployment

2. Calculate the unemployment rate for each year: Unemployment rate = (Unemployment / Labor force) * 100

3. Calculate the labor force participation rate for each year: Labor force participation rate = (Labor force / Total adult population) * 100

2019:

1. Labor force = 100,000 (employment) + 5,000 (unemployment) = 105,000

2. Unemployment rate = (5,000 / 105,000) * 100 = 4.76%

3. Labor force participation rate = (105,000 / 150,000) * 100 = 70%

2020:

1. Labor force = 75,000 (employment) + 15,000 (unemployment) = 90,000

2. Unemployment rate = (15,000 / 90,000) * 100 = 16.67%

3. Labor force participation rate = (90,000 / 155,000) * 100 = 58.06%

Based on the changes in the unemployment rate and labor force participation rate between 2019 and 2020, it appears that the economy of Manga was in the contraction phase of the business cycle at the end of 2020. This is because the unemployment rate increased significantly and the labor force participation rate decreased, indicating a shrinking economy.

Note: The question is incomplete. The complete question probably is: Given the information below for the country of Manga, answer the following: Calculate the unemployment rates for both 2019 and 2020. Then calculate the labor force participation rates for both 2019 and 2020.

To create a 10" by 10" grid using 1" pieces of wire, you will need to increase a total of 110 pieces of wire. This includes 100 "place" wires to form the grid squares, and 10 additional "piece" wires on each side to complete the border.

To create a similar 10'' by 10'' grid, we would need to increase each side by a factor of 10/6 or 5/3. This means that each piece of wire in the original 6'' by 6'' grid would need to be extended by 5/3, making it 5/3 inches long.

The number of pieces of wire needed for the new grid can be calculated by using the formula:

Number of pieces of wire = (number of horizontal wires + number of vertical wires + diagonals) x length of each wire

For the original 6'' by 6'' grid, there are 7 horizontal wires, 7 vertical wires, and 10 diagonals (which can be counted by drawing lines from each corner to the opposite corner). So the total number of wires is:

(7 + 7 + 10) x 1 = 24

For the new 10'' by 10'' grid, there will be 11 horizontal wires, 11 vertical wires, and 16 diagonals. So the total number of wires needed is:

(11 + 11 + 16) x (5/3) = 64.44 (rounded up to the nearest whole number)

Therefore, we would need approximately 64 pieces of wire to create a similar 10'' by 10'' grid.

The exponential function y = \(3^x\) grows at a faster rate than the quadratic function for x > 0.

The exponential function that grows at a faster rate than the quadratic function for x > 0 is y = \(3^x\).

To see why, let's first look at the rate of change of the quadratic function.

We can find this by looking at the differences between consecutive y-values:
1 - 0 &= 1
3 - 1 &= 2
12 - 3 &= 9
27 - 12 &= 15
$$We can see that the rate of change is increasing as x increases.

For example, the rate of change between the first two points is 1, while the rate of change between the last two points is 15.

However, this rate of change is still constant within each interval of x-values.

y = \(3^x \\\)  

Let's take a look at its y-values for the same x-values as in the table:
\(3^0\) &= 1

\(3^1\) &= 3
\(3^2\) &= 9
\(3^3\) &= 27
$$We can see that the rate of change is not constant, but rather increasing, just like in the quadratic function.

However, the rate of change is greater for y = \(3^x\).

For example, the rate of change between the first two points is 2, while the rate of change between the last two points is 18.

The net of a triangular prism consists of two triangles and three rectangles.

In the net of a triangular prism, we can observe two types of polygons: triangles and rectangles.

First, let's discuss the triangles.

A triangular prism has two triangular faces, which are congruent to each other.

These triangles are equilateral triangles, meaning they have three equal sides and three equal angles.

Each of these triangles contributes two polygons to the net, one for each face.

Next, we have the rectangles.

A triangular prism has three rectangular faces that connect the corresponding sides of the triangular bases.

These rectangles have opposite sides that are parallel and equal in length.

Each rectangle contributes one polygon to the net, resulting in a total of three rectangles.

To summarize, the net of a triangular prism consists of two equilateral triangles and three rectangles.

The triangles represent the bases of the prism, while the rectangles form the lateral faces connecting the bases.

Altogether, there are five polygons in the net of a triangular prism.

Answer:

4 is the correct answer, I believe.

Reasoning:

The first line must be graphed with a constant y of 3, and stop before -2. Which it does on all 4 graphs.

The third line must, when extended, pass through point (0, -3). Only graph 1 and 4 follow that criteria, so it is not 2 or 3.

The second line's y-intercept must be 2, as well as begin at -2 and end before 2. Only graph 4 correctly plots this equation.
