What is the median of the data set?
7, 9, 11, 14, 18, 20, 30, 35
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.
\(\sf Median = \frac{14+18}{2}\\\\ \sf Median = \frac{32}{2}\\\\\sf Median = 16\)

Round volume to nearest tenth
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:
\(V=223.3062+689.6424\\V=912.9486\)

If if Spencer spent a total of $704.00 in the month of July, which is the best estimate for the amount of money he spent on clothing?
Answer:
\(Clothing = \$190.0\)
Step-by-step explanation:
Given [Missing details]
Spencer's expenses
\(Clothing = 27\%\)
\(Gasoline = 11\%\)
\(Food = 44\%\)
\(Entertainment = 18\%\)
\(Total= \$704.00\)
Required:
An estimate for the amount spent on clothing
To do this, simply multiply the clothing percentage by the total amount.

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).
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
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:
\(\begin{gathered} tan36=\frac{8}{CD} \\ \\ CD=\frac{8}{tan36} \\ \\ CD=\frac{8}{0.72654} \\ \\ CD=11 \end{gathered}\)Therefore, the length of CD is 11 units.

Find the tangents of the acute angles in the right triangle. Write each answer as a fraction. WILL MAKE BRAINLIEST!!
tan G = ?
tan H = ?
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

ANSWER QUICKLY PLEASE 2. Molecules in the air are moving with speeds based on the normal model.
a. If half of the air molecules are moving faster than 760 m/s, what does this indicate about our data?
b. If exactly 95% of the molecules are moving with speeds between 475.8 m/s and 1044.2 m/s, what does this indicate the standard deviation is for our normal model?
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?
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.
A boat can travel 412 miles on 103 gallons of gasoline. How much gasoline will it need to go 184 miles?
Hey there! I'm happy to help!
Let's set this up as a proportion (2 equal ratios).
\(\frac{miles}{gallons} =\frac{412}{103} =\frac{184}{g}\)
If you multiply the diagonal numbers, their products will be equal. (412×g=103×184). This is called cross multiplying. Now we can solve for g.
412g=18952
Divide both sides by 412.
g=46
Therefore, the boat will need 46 gallons of gasoline to go 184 miles.

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%.

Aaron tracks the time it takes him to mow lawns by writing coordinate points relating x, the time in hours it takes to mow a lawn, and y, the area of land mowed in acres. Two of his points are (3, 1.5) and (5, 2.5). Which statement describes the slope of the line through these two points? It takes Aaron about 1 hour to mow 2 acres. Aaron’s rate for mowing lawns is 0.5 acres per hour. The ratio of acres to time is 5 acres to 3 hours. The rate to mow a lawn is 0.6 hours per acre.
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.

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?
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?
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.
