In a strongly right-skewed data set, the median will be smaller than the mean. This implies that the majority of the data points are concentrated towards the lower end of the distribution, resulting in a longer tail on the right side.

The median represents the middle value of a data set when arranged in ascending order. Since the tail on the right side of the distribution is stretched due to the skewness, the median will be pulled towards the lower values, making it smaller than the mean.

The mean, on the other hand, takes into account the values of all data points and is influenced by extreme values. In a right-skewed distribution, the presence of a few very high values on the right side can significantly increase the mean. Therefore, the mean will be larger than the median, indicating the overall shift towards higher values caused by the skewness.

Answer:

The total of the discount would be 1,360.

Step-by-step explanation:

If a 6,800$ item had a 20% discount, subtract 6,800 by 20 in percentage, therefore the result would be 1,360 in discount.

To solve this expression, you can first simplify the fractions:

5/11 * -11/6 = (-5/6) * (-6/5)

Then, you can multiply the fractions:

(-5/6) * (-6/5) = (-30/30) = -1

So, the result of the expression is -1.

The case fatality rate is 400 * 100 / 1500 = 26.67 (option d).

For the first scenario, the data determine that there is a difference in average expenditure between the two countries (option c). The P-value of 0.063 suggests that there is a moderate level of statistical significance, indicating that the difference in average expenditure is likely not due to random chance.

In the second scenario, the fact that the 95% confidence interval for the average number of times participants saw their provider per year (3.3) ranges from 0.1 to 6.1 is of statistical use because it provides a range estimate within which the true population means is likely to fall. This interval helps account for the uncertainty associated with the sample estimate and provides a measure of the precision of the estimate (option a).

For the third scenario, the average operating margin is appropriate to use because it is a measure of central tendency that represents the typical financial performance of rural hospitals. The standard deviation provides information about the variability of the operating margins (option d).

In the fourth scenario, the consideration factor that will ultimately contribute to the spread of Ebola is the population density of the affected area (option b). While factors like the influence of non-indigenous people and climatic conditions may play a role, population density is a key determinant in the transmission and spread of infectious diseases.

For the fifth scenario, the case fatality rate is calculated by dividing the number of deaths from the disease (400) by the total reported cases (1500) and multiplying by 100. Therefore, the correct calculation is 400 * 100 / 1500 = 26.67 (option d). This indicates that the case fatality rate is approximately 26.67%.

Answer:

Step-by-step explanation:

When we add the area of semicircle I and III  of same radius, we get a cirlce.

diameter = 48 cm

r = 48/2 = 24 cm

Area of I and III = area of circle

                         = πr²

                         = 3.14 * 24 *24

                         = 1808.6 cm²

Figure II:

length =  diameter of the bigger semicircle = 48 cm

width = diameter of the smaller circle = 14 cm

Area of rectangle (figure II) = length *width

                                            = 48 * 14

                                            = 672 cm²

Smaller semicircle A & B

diameter = 14 cm

r = 14/2 = 7 cm

Area of Semicircle A & B = Area of a circle

                                         \(\sf = \dfrac{22}{7}*7*7\\\\ = 22*7\\\\= 154 \ cm^{2}\)

Area of shaded region =  area of rectangle II + area of figure I & III - area of A &B

            = 672 + 1808.6   - 154

           =  2326.6cm²

Step-by-step explanation:

Doubles fact is the doubled value that is easy to remember , but doubles fact are easily to remember when they are small number .

e.g. doubles fact for 8 is 16 as 8+8 = 16.

Some double facts are:

1's = 1+1 = 2.

2's = 4

3's = 6

4's = 8

etc.

The reason teachers use double facts to teach students is because they provide a faster way to find the answer to addition problems that are not as easy to memorize.

e.g. if we need to find value for 8 + 9

then we can split this in doubles fact of 8 as:

8+8+1  (writing 9 as sum of 8 and 1)

And solution will be as 8+8+1 = 16+1

Therefore , as a result, A = 84.3 sq unit is the answer to the pentagon presented challenge.

In geometry, a penta is a polygon having five sides. A simple pentagon's interior angles add up around 540°. It is possible to create simple or self-intersecting pentagons. A regular pentagon that intersects itself is a pentagram. A 2D polygon with five sides and 5 corners is called a pentagon. The English word "five" is derived from the Greek terms "gon" and "penta." The outcome of mixing the two syllables "Penta + Gon" is Pentagon.

Here,

The equation that is widely used to determine the area of the any regular hexagon that use the apothem or side is

Step-by-step explanation:

We are to multiply the expression (7y^3/5)(6x+5/21y)

(7y^3/5)(6x+5/21y) = 7 * y * y * y/5 * 6x+5/21y

(7y^3/5)(6x+5/21y)  = y²/5 * 6x+5/3

(7y^3/5)(6x+5/21y) = y²(6x+5)/5*3

(7y^3/5)(6x+5/21y) = y²(6x+5)/15

Hence the product is y²(6x+5)/15

The stationing of the end of the excavation is Station 2+080.

The volume of fill by end area method is 1440 cubic meters.

The volume of excavation by end area is 1080 cubic meters.

We have,

The stationing of the end of excavation can be determined by adding the given sections to the starting station.

Assuming the starting station is Station 2+020, the end of excavation would be at Station 2+080 (given as Station 2+020 + 60 meters).

To find the volume of fill by end area method, we need to calculate the area of the end section and multiply it by the distance between the start and end stations.

Given that the base for fill is 12 meters and the sideslope for fill is 2:1, the area of the end section can be calculated as follows:

Area of end section = (Base for fill) * (Sideslope for fill)

Area of end section = 12 * (2/1) = 24 square meters

Now, multiply the area of the end section by the distance between the start and end stations (60 meters) to find the volume of fill:

Volume of fill = Area of end section * Distance

Volume of fill = 24 * 60 = 1440 cubic meters

Therefore, the volume of fill by end area method is 1440 cubic meters.

Similarly, to compute the volume of excavation by end area, we calculate the area of the end section (base for cut * sideslope for cut) and multiply it by the distance between the start and end stations. Given that the base for cut is 12 meters and the sideslope for cut is 1.5:1, the area of the end section can be calculated as follows:

Area of end section = (Base for cut) * (Sideslope for cut)

Area of end section = 12 * (1.5/1) = 18 square meters

Multiply the area of the end section by the distance between the start and end stations (60 meters) to find the volume of excavation:

Volume of excavation = Area of end section * Distance

Volume of excavation = 18 * 60 = 1080 cubic meters

Therefore, the volume of excavation by end area is 1080 cubic meters.

Thus,

The stationing of the end of the excavation is Station 2+080.

The volume of fill by end area method is 1440 cubic meters.

The volume of excavation by end area is 1080 cubic meters.

The consequences of Type I and Type II errors in this context have different impacts on the transportation officials and the drivers, and their levels of anger would vary depending on the error committed.

What is the mean and standard deviation?

The standard deviation is a summary measure of the differences of each observation from the mean. If the differences themselves were added up, the positive would exactly balance the negative and so their sum would be zero. Consequently, the squares of the differences are added.

(a) The null hypothesis (H₀) and alternative hypothesis (Ha) can be formulated as follows:

Null hypothesis (H₀): The mean number of cars per day that cross the Tappan Zee Bridge has not increased.

Alternative hypothesis (Ha): The mean number of cars per day that cross the Tappan Zee Bridge has increased.

(b) Type I error: In the context of the problem, a Type I error would occur if the null hypothesis (H₀) is rejected, indicating that the mean number of cars per day has increased when it actually has not. This means that the transportation officials would conclude that the tolls need to be raised to fund repairs based on incorrect evidence.

Type II error: A Type II error would occur if the null hypothesis (H₀) is not rejected, indicating that the mean number of cars per day has not increased when it actually has. In this case, the transportation officials would fail to raise the tolls despite the actual increase in the number of cars crossing the bridge, potentially leading to insufficient funding for the repairs.

(c) If a Type I error is committed, the transportation officials would be more angry. This is because they would have mistakenly raised tolls based on incorrect evidence, which could lead to public backlash, dissatisfaction, and criticism. The drivers, on the other hand, may also be frustrated by increased tolls, but they would not be as directly affected by a Type I error as the transportation officials.

(d) If a Type II error is committed, the drivers would be more angry. This is because the transportation officials would have failed to raise tolls despite the actual increase in the number of cars crossing the bridge. This could lead to delays in repair funding and potentially worsen the condition of the bridge, causing inconvenience and safety concerns for the drivers who rely on it.

The transportation officials may also face criticism for not taking appropriate action in a timely manner, but the direct impact on the drivers would be more significant in this case.

Therefore, the consequences of Type I and Type II errors in this context have different impacts on the transportation officials and the drivers, and their levels of anger would vary depending on the error committed.
