Answer:
The interquartile range is the difference between the highest and lowest values in the middle of a data set.
Step-by-step explanation:
The range is the difference between the maximum and minimum value, hence, it cannot be greater than the maximum value, which is the greatest value in a dataset, the highest value a range could have being equal to the maximum value when the minimum vlaue of the dataset is equal to 0.
The mean is the average value of a dataset, hence, it cannot be greater than the maximum value.
The interquartile range is the middle 50% or half of a dataset and not the difference between the highest and lowest middle values in the middle. It is obtained by taking the difference of the upper and lower QUARTILE.

Answer:
The sales tax would be $6.71 :)
Step-by-step explanation:
110 x 0.061 = 6.71
116.71
Step-by-step explanation:
if the tax rate is 6.1 that wiild equal 6.71 then you would add 6.71 to 110 which the answer would be 116.71
The amount of time (in minutes per day) spent on social media for a sample of 10 teens has a mean of 186.7 and a sample standard deviation of 19.99. An independent sample of 8 older adults has a mean of 93.5 minutes with a sample standard deviation of 32.01. Assume that the time spent on social media is approximately normally distributed for each group. a) Determine the value of the test statistic to test H subscript 0 colon space mu subscript t e e n end subscript equals mu subscript o l d e r end subscript against H subscript A colon space mu subscript t e e n end subscript not equal to mu subscript o l d e r end subscript. b) Determine the p-value or critical value for this test at alpha equals 0.05. c) What is your conclusion about whether the two age groups spend the same average amount of time on social media

A statewide real estate sales agency, Farm Associates, specializes in selling farm property in the state of Nebraska. Its records indicate that the mean selling time of farm property is 90 days. Because of recent drought conditions, the agency believes that the mean selling time is now greater than 90 days. A statewide survey of 100 farms sold recently revealed that the mean selling time was 94 days, with a standard deviation of 22 days.
Required:
At the 0.10 significance level, has there been an increase in selling time?
Answer:
The right answer is "1.818".
Step-by-step explanation:
The given values are:
a = 0.1
[tex]\bar{x} = 94[/tex]
[tex]\mu = 90[/tex]
Now,
The test statistic will be:
⇒ [tex]t=\frac{\bar{x}-\mu}{\frac{s}{vn} }[/tex]
On substituting the given values, we get
⇒ [tex]=\frac{94-90}{\frac{22}{10} }[/tex]
⇒ [tex]=\frac{4}{2.2}[/tex]
⇒ [tex]=1.818[/tex]

Use linear regression to find a
function that fits the following
points.
(0,5), (2,-13)
Answer:
Function that fits the points [tex](0,5),\,(2,-13)[/tex] is given by [tex]x+9y=45[/tex]
Step-by-step explanation:
Let [tex](x_1,y_1)=(0,5),\,(x_2,y_2)=(2,-13)[/tex]
Slope of a line joining points [tex](x_1,y_1),\,(x_2,y_2)[/tex] is given by [tex]m=\frac{x_2-x_1}{y_2-y_1}[/tex]
[tex]=\frac{2-0}{-13-5}[/tex]
[tex]=\frac{2}{-18}[/tex]
[tex]=\frac{-1}{9}[/tex]
Equation of a line joining points [tex](x_1,y_1),\,(x_2,y_2)[/tex] is given as follows:
[tex]y-y_1=m (x-x_1)[/tex]
[tex]y-5=\frac{-1}{9}(x-0)\\y-5=\frac{-1}{9}x\\9(y-5)=-x\\9y-45=-x\\x+9y=45[/tex]

Answer:
Option 1
Step-by-step explanation:
In the first one, the first number is lower than -2, the second is between -1 and 0, and 1+1/6 is of course bigger than 0 and smaller than 1+5/6, so it's the right answer.
The second one is the first one reversed, so it's ordered from greatest to lowest.
The third one has a negative number on both ends, but positives in the middle, so it cannot be ordered lowest to greatest. Same with the last one.

The height , in feet, windowsills in a high-rise building is represented by this sequence: 3,15,27,39,...
Answer:
Each windowsill goes up by a factor of 12 feet, so the next numbers are 51, 63, 75(feet) and so forth
Step-by-step explanation:
3, 15, 27, 39.....
3+12= 15
15+12= 27
27+12= 39
39+12= 51
51+12= 63
63+ 12= 75
What is its domain?
What is its range?
Write the answer in interval notation.
Answers:
Domain = [-3, 3]
Range = [-1, 2]
=============================================
Explanation:
The domain is the set of all allowed x inputs. Visually, the left-most point is when x = -3, so -3 is the smallest allowed x input. We have a closed circle at this endpoint, so this endpoint x value is included. In contrast, if you had an open circle, then you would exclude the endpoint.
Similarly, we have a closed endpoint at the other side as well when x = 3. This is the largest allowed x value. The domain is the set of x values such that [tex]-3 \le x \le 3[/tex] meaning x is between -3 and 3, including both endpoints. This translates to the interval notation of [-3, 3]. The square brackets say "include the endpoint".
------------
The range is the set of possible y outputs of a function. The lowest the function goes is when y = -1, and the highest is when y = 2. We include both endpoints. The range as a compound inequality is [tex]-1 \le y \le 2[/tex] which converts to the interval notation of [-1, 2]

A right triangle has a leg of 12 cm and a hypotenuse of 19 cm.
What is the length of the other leg?
Round to the nearest tenth.
-----------------------------------------
7.0 cm
14.7 cm
22.5 cm
217.0 cm
Answer:
14.7 cm
Step-by-step explanation:
Using Pythagoras Theorem,
The length of the other leg
[tex] = \sqrt{ {19}^{2} - {12}^{2} } [/tex]
[tex] = \sqrt{217} [/tex]
[tex] = 14.730919...[/tex]
= 14.7 cm (rounded to the nearest tenth)
