What is the median of the data set?
7, 9, 11, 14, 18, 20, 30, 35

Answers

Answer:

16

Step-by-step explanation:

To find the median, we find the middle of the data set.

7, 9, 11, 14, 18, 20, 30, 35

There are 8 values

7, 9, 11,    14, 18,     20, 30, 35

The median is between the 4th and 5th numbers

We need to find the mean of the middle two numbers

(14+18)/2 =32/2= 16

Answer:

16

Step-by-step explanation:

Median means the middle term in a data set.Remember that, you have to arrange the data points from smallest to largest to find the median of a data set.The formula to find the median of a data set is:

             \(\sf (\frac{n+1}{2}\:)^ t^h \:data\)

       Here,

             n ⇒ number of terms

Let us find it now.

7, 9, 11, 14, 18, 20, 30, 35

\(\sf Median=\sf (\frac{n+1}{2}\:)^ t^h \:data\\\\\sf Median=\sf (\frac{8+1}{2}\:)^ t^h \:data\\\\\sf Median=\sf 4.5^ t^h \:data\)

In this case, add 4th and 5th data and divide it by 2.

\(\sf Median = \frac{14+18}{2}\\\\ \sf Median = \frac{32}{2}\\\\\sf Median = 16\)

Answer:

volume= \(912.9ft^{3}\) (not sure how you want to round the answer. it could be rounded to 913 or left as 912.9)

Step-by-step explanation:

volume of cone: to find the height of the cone, subtract the cylinder height from the total height (H-h= cone height)

\(V=\pi r^2\frac{h}{3} \\V=\pi (5.6)^2(\frac{6.8}{3} )\\V=\pi (31.36)(2.2666...)\\V=71.08057\pi \\V=223.3062\)

volume of cylinder:

\(V=\pi r^2h\\V=\pi (5.6)^2(7)\\V=\pi (31.36)(7)\\V=219.52\pi \\V=689.6424\)

add them together:

\(V=223.3062+689.6424\\V=912.9486\)

Answers

Answer:

Mean = 59.1, Median = 61

(there might have been a mistake in calculation (a lot of numbers!))

Step-by-step explanation:

The sample size is 40,

Now, the formula for the mean is,

Mean = (sum of the sample values)/(sample size)

so we get,

\(Mean = (49+63+78+22+41+39+75+61+63+65+58+37+45+52+81+75+78+72+68+59+72+85+63+61+75+39+41+48+59+55+61+25+61+52+58+71+75+82+49+51)/40\\Mean = 2364/40\\Mean = 59.1\)

To find the median, we have to sort the list in ascending (or descending)order,

we get the list,

22,25,37,39,39,41,41,45,48,49,

49,51,52, 52,55,58, 58, 59, 59, 61,

61, 61, 61, 63, 63, 63, 65, 68, 71, 72,

72, 75, 75, 75, 75, 78, 78, 81, 82, 85

Now, we have to find the median,

since there are 40 values, we divide by 2 to get, 40/2 = 20

now, to find the median, we takethe average of the values above and below this value,

\(Median = ((n/2+1)th \ value + (n/2)th \ value )/2\\where, \ the\ (n/2)th \ value \ is,\\n/2 = (total \ number \ of \ samples) /2\\n/2=40/2\\(n/2)th = 20\\Hence\ the (n/2)th \ value \ is \ the \ 20th \ value\)

And the (n+1)th value is the 21st value

Now,

The ((n/2)+1)th value is 61 and the nth value is 61, so the median is,

Median = (61+61)/2

Median = 61

What is the slope of line p? on a coordinate plane, a straight line goes through (negative 3, negative 2), (0, 0), and (3, 2).

Answers

Slope line formula is used for determining the slope of a line. Based on the given points, the slope of line is 2/3.

To find the slope of the line passing through the given points, we can use the slope formula, which states that the slope of a line passing through two points (x1, y1) and (x2, y2) is given by the expression:

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

Using this formula, we can calculate the slope of the line passing through the three given points as follows:

slope = (2 - (-2)) / (3 - (-3)) = 4/6 = 2/3

Therefore, the slope of the line passing through the given points is 2/3.

Alternatively, we can observe that the three points are collinear and lie on the same straight line. We can use this fact to find the slope of the line by computing the rise over run between any two of the points. For example, using the points (0,0) and (-3,-2), we have a rise of 2 and a run of 3, so the slope is 2/3. This confirms that the slope of the line passing through the given points is 2/3.

use the triangles to help answer part A,B and C

use the triangles to help answer part A,B and C

Answers

Given:

We have the two triangles:

ABC and ADC

Where:

AB = 10

AC = 8

Let's solve for the following:

• (a). Write a similiarity statement for the two similar triangles.

Two triangles are similar if their corresponding sides are in proportion.

To write a siiliarity statement, we have:

ΔABC ~ ΔADC

• (b). Let's find the length of BC.

To solve for BC, since ABC is a right traingle, apply Pythagorean Theorem:

\(\begin{gathered} AB^2=AC^2+BC^2 \\ \\ BC^2=AB^2-AC^2 \\ \end{gathered}\)

Where:

AB = 10

AC = 8

Thus, we have:

\(\begin{gathered} BC^2=10^2-8^2 \\ \\ BC^2=100-64 \\ \\ BC^2=36 \\ \\ BC=\sqrt{36} \\ \\ BC=6 \end{gathered}\)

• (c). Let's find the length of CD.

Since they are similar triangles, the corresponding angles will be equal.

Thus, angle D = angle B = 36 degrees.

Now, apply the trigonometric ratio for tangent:

\(tan\theta=\frac{opposite}{adjacent}\)

Where:

Opposite side = AC = 8 units

Adjcaent side = CD

Hence, we have:

\(\begin{gathered} tan36=\frac{8}{CD} \\ \\ CD=\frac{8}{tan36} \\ \\ CD=\frac{8}{0.72654} \\ \\ CD=11 \end{gathered}\)

Answers

The tangents of the acute angles in the right triangle gives:

tan(G) = 2

tan(H) = 1/2

How to find the tangents of angles?

It should be noted that tangent is the ratio of opposite over adjacent. Thus:

tan(angle) = opposite/adjacent

So for reference angle G, we say,

tan(G) = JH/GJ = 2/1 = 2

We'll treat tan(H) in a similar fashion, but the opposite and adjacent sides swap roles. That means we'll apply the reciprocal to the result above to get 1/2 for tan(H)

So we have this interesting property where

tan(G)*tan(H) = 2*(1/2) = 1

c. One molecule is found to be moving with a speed of 1127 m/s. Would this be considered a usual or unusual speed?

d. Increasing the temperature of the air particles are traveling in causes the mean particle speed to increase, but the particles still have the same standard deviation. If the temperature increase caused the z-score of a particle moving at 1100 m/s particle to drop to 1.2 after the temperature increase, now how fast is the average molecule moving?

Answers

Answer:

(a). The mean speed is 760 m/s.

(b). The standard deviation for our normal model is 142.1 m/s.

(c). The unusual speed is 1127 m/s.

(d). The average molecule speed is 929.48 m/s.

Step-by-step explanation:

Given that,

Molecules in the air are moving with speeds based on the normal model.

Let x be the speed of the molecules.

(a). If half of the air molecules are moving faster than 760 m/s.

We can say speed of a molecules is normally distributed.

So, the mean, median and mode of this distribution is at least greater than 760 m/s.

(b). If exactly 95% of the molecules are moving with speeds between 475.8 m/s and 1044.2 m/s,

If the standard deviation is σ and the mean is μ,

We need to calculate the standard deviation for our normal model

Using empirical rule

\(\mu-2\sigma=475.8\)...(I)

\(\mu+2\sigma=1044.2\)....(II)

Put the value of μ in equation (I)

\(760-2\sigma=475.8\)

\(-\sigma=\dfrac{475.8-760}{2}\)

\(\sigma=142.1\ m/s\)

(c). One molecule is found to be moving with a speed of 1127 m/s.

We know that,

1127 is the between 1126 and 1128.

Since, it is a continuous distribution,

We need to find the probability that speed is between this

Using excel function

\(P(1126<x<1128)=P(x<1128)-P(x<1126)\)

\(P(1126<x<1128)=0.0002\)

We know that,

Any probability less than 0.05 is considered as unusual

So, 0.0002<0.05

So, 1127 will be considered as the unusual speed.

(d). If the temperature increase caused the z-score of a particle moving at 1100 m/s particle to drop to 1.2 after the temperature increase.

We need to calculate the average molecule speed

Using formula of average molecule speed

\(z=\dfrac{x-\mu'}{\sigma}\)

\(-\mu'=z\sigma-x\)

Put the value in to the formula

\(-\mu'=1.2\times142.1-1100\)

\(\mu'=929.48\ m/s\)

Hence, (a). The mean speed is 760 m/s.

(b). The standard deviation for our normal model is 142.1 m/s.

(c). The unusual speed is 1127 m/s.

(d). The average molecule speed is 929.48 m/s.

The maximum error in the calculated area of the disk is 26.39 cm². The percentage error is 3.73%. (Round your answer to two decimal places.)

The radius of a circular disk is given as 15 cm with a maximum error in measurement of 0.28 cm.

Use differentials to estimate the maximum error in the calculated area of the disk.

We know that the formula for the area of a circle is given by:

A = πr²

where r is the radius of the circle.

Using differentials, we have:

dA = 2πrdr

Substituting the given values:

r = 15 cm and dr = 0.28 cmdA = 2π(15)(0.28)dA ≈ 26.39 cm²

Therefore, the maximum error in the calculated area of the disk is 26.39 cm².

The relative error is given by the formula:

Relative error = (Error in measurement / Actual value) × 100%

The actual value of the area of the disk is given by:

A = π(15)²A = 706.86 cm²

Substituting the values we calculated earlier, we have:

Relative error = (26.39 / 706.86) × 100%

Relative error ≈ 3.73%

Therefore, the relative error is approximately 3.73%.

The percentage error is the same as the relative error, which is 3.73%.

Therefore, the percentage error is 3.73%.

Answers

Answer: Aaron’s rate for mowing lawns is 0.5 acres per hour

Step-by-step explanation:

Hope this helps!!

The statement "The rate to mow a lawn is 0.5 acres per hour" correctly describes the slope of the line passing through the given points.

We have,

To determine the slope of the line passing through the points (3, 1.5) and (5, 2.5), we can use the slope formula:

Slope = (change in y) / (change in x)

Given the two points, we can calculate the change in y and the change in x:

Change in y = 2.5 - 1.5 = 1

Change in x = 5 - 3 = 2

Plugging these values into the slope formula:

Slope = 1 / 2 = 0.5

The slope represents the rate of change of the y-coordinate (area) with respect to the x-coordinate (time).

In this case, a slope of 0.5 means that for every hour it takes Aaron to mow a lawn (change in x), the area mowed (change in y) increases by 0.5 acres.

Therefore,

The statement "The rate to mow a lawn is 0.5 acres per hour" correctly describes the slope of the line passing through the given points.

The z-statistic test was conducted to determine the Deviation of RPM, ASM, and LF from the mean. The test indicates that RPM, ASM, and LF significantly deviate from the mean.

Report on the Analysis of American Airlines (Domestic) PerformanceThe quantitative analysis focused on three variables- load factors, revenue passenger miles, and available seat miles for American Airlines.

The Bureau of Transportation Statistics data for domestic flights from January 2006 to December 2012 was retrieved for the analysis. The quantitative analysis also focused on finding critical statistical values like mean, median, mode, standard deviation, variance, and minimum/maximum variables. The results of the data are summarized in Table 2. Revenue Passenger Miles (RPM) mean is 6,624,897, the median is 6,522,230, and mode is NONE. The minimum is 5,208,159 and the maximum is 8,277,155. The standard deviation is 720,158.571, and the variance is 518,628,367,282.42.

Load Factors (LF) mean is 82.934, the median is 83.355, and mode is 84.56. The minimum is 74.91, and the maximum is 89.94. The standard deviation is 3.972, and the variance is 15.762. The Available Seat Miles (ASM) mean is 7,984,735, the median is 7,753,372, and mode is NONE. The minimum is 6,734,620, and the maximum is 9,424,489. The standard deviation is 744,469.8849, and the variance is 554,235,409,510.06.Figure 1 above displays the performance of American Airlines (Domestic).

The mean RPM is 7,984,735, and the linear regression line is y = 50584x - 2.53E+8. The linear regression line indicates a positive relationship between RPM and year, with a coefficient of determination, R² = 0.6806. A coefficient of determination indicates the proportion of the variance in the dependent variable that is predictable from the independent variable. Therefore, 68.06% of the variance in RPM is predictable from the year. A one-way ANOVA analysis of variance test was conducted to determine the equality of means of three groups of variables; RPM, ASM, and LF. The null hypothesis is that the means of RPM, ASM, and LF are equal.

The alternative hypothesis is that the means of RPM, ASM, and LF are not equal. The level of significance is 0.05. The ANOVA results indicate that there is a significant difference in means of RPM, ASM, and LF (F = 17335.276, p < 0.05). Furthermore, a post-hoc Tukey's test was conducted to determine which variable means differ significantly. The test indicates that RPM, ASM, and LF means differ significantly.

The skewness test was conducted to determine the symmetry of the distribution of RPM, ASM, and LF. The test indicates that the distribution of RPM, ASM, and LF is not symmetrical (Skewness > 0).

Additionally, the z-statistic test was conducted to determine the deviation of RPM, ASM, and LF from the mean. The test indicates that RPM, ASM, and LF significantly deviate from the mean.

richard's estate is to be split equally among his three children. if his estate is worth $3 4/5 million, how much will each child inherit?

Answers

Answer:

B

Step-by-step explanation: im pretty sure

2) In reply to an inquiry about the animals on his farm, the farmer says: "I
only ever keep sheep, goats, and horses. In fact, at the moment they are
all sheep bar three, all goats bar four, and all horses bar five." How many
does he have of each animal?

Answers

The number of horse is 1, goat is 2 and sheep is 3 a man has.

The problem we are dealing with is related to the linear equation which is referred to as the algebraic condition where each term has an exponent of 1 and when this condition is graphed, it continuously comes about in a straight line.

Now w consider x to be the number of sheep, y to be the  number of  goats, and z to be the number of horses the man owns.

the actual equation for the total number of animals he owns  is :

x+ y+ z

according to the first condition:

that all sheep bar three, means

y+ z=3

similarly, for the other condition, it will be

x+ z=4   and x+ y=5

Now we adding the three  equations:

y + z +x +z +x +y=5+4 +3

2(x+y+z)=12

x+y+z=6........equation(1)

As x + y = 5

Put this in equation in (1), we get

x+y+z = 6

5 + z = 6

z = 1

x + z = 4

x + y + z = 6

y + 4 = 6

y = 2

Now we know

x + y + z = 6

x + 1 + 1 = 6

x = 4

So simplifying the other equation  we get, that the number of horse is 1, goat is 2, and sheep is 4.

Local Klan-like groups continued to engage in racial and political terrorism, often calling themselves minutemen or rifle clubs, but they lacked larger organizational ties or even commonality of purpose. A romanticized memory of the first KKK legitimated their activities and, combined with the growing power of a Lost Cause mythology, contributed greatly to Georgians' acceptance of vigilante violence and lynching well into the twentieth century. By the 1890s, many men proudly claimed to have ridden with the Klan and thereby saved Georgia and the South from "Negro domination." This romanticized vision of the Klan was celebrated in popular novels and laid the foundation for the more openly organized Knights of the Ku Klux Klan, the second Ku Klux Klan, founded in Atlanta in 1915.Ku Klux Klan in the Reconstruction Era,Jonathan M.
