Step-by-step explanation:
The 16 possible permutations and their means are:
47, 47: μ = 47
47, 30: μ = 38.5
47, 28: μ = 37.5
47, 18: μ = 32.5
30, 47: μ = 38.5
30, 30: μ = 30
30, 28: μ = 29
30, 18: μ = 24
28, 47: μ = 37.5
28, 30: μ = 29
28, 28: μ = 28
28, 18: μ = 23
18, 47: μ = 32.5
18, 30: μ = 24
18, 28: μ = 23
18, 18: μ = 18
So the frequency distribution of the sample means is:
[tex]\left[\begin{array}{cc}Mean&Frequency\\18&1\\23&2\\24&2\\28&1\\29&2\\30&1\\32.5&2\\37.5&2\\38.5&2\\47&1\end{array}\right][/tex]
The mean of a dataset is the average value of the dataset.
The dataset is given as:
47, 30, 28 and 18
From the above dataset, we can see that the data elements are 4
The sample size is given as:
n = 2
So, the number of different samples is:
[tex]Samples = 4^2[/tex]
[tex]Samples = 16[/tex]
The 16 samples are: {(47,47), (47,30), (47,28), (47,18),(30,47), (30,30), (30,28), (30,18),(28,47), (28,30), (28,28), (28,18),(18,47), (18,30), (18,28), (18,18)}
The mean values of the above samples are: {47, 38.5, 37.5 , 32.5 , 38.5 , 30 , 29 , 24 , 37.5 , 29 , 28 , 23 , 32.5 , 24 , 23 , 18}
Rearrange in ascending order
18, 23, 23, 24, 24, 28, 29,29, 30, 32.5, 32.5, 37.5, 37.5, 38.5, 38.5, 47
So, the table of the sample means is:
Mean Frequency
18 1
23 2
24 2
28 1
29 2
30 1
32.5 2
37.5 2
38.5 2
47 1
Total 16

15. Pat and Camilla are working with expressions with rational exponents. Listed below are what each
believes to be correct. Use the properties of exponents to determine the correct answer. Write
the correct answer in the space provided.
Answer:
Step-by-step explanation:
Pat believes that [tex]\sqrt{2}+\sqrt{8}=(2)(2)^{\frac{1}{2}}[/tex]
[tex]\sqrt{2}+\sqrt{8}=\sqrt{2}+\sqrt{4\times 2}[/tex]
[tex]=\sqrt{2}+2\sqrt{2}[/tex]
[tex]=3\sqrt{2}[/tex]
[tex]=3(2)^{\frac{1}{2} }[/tex]
But [tex]2(2)^{\frac{1}{2}}\neq 3(2)^{\frac{1}{2}}[/tex]
Therefore, Pat's belief is not correct.
Camilla believes that [tex]\sqrt{2}+\sqrt{8}=3\sqrt{2}[/tex]
Which is correct as we have calculated above.
Therefore, [tex]\sqrt{2}+\sqrt{8}=3\sqrt{2}[/tex] will be the correct answer.

7,680,000
__________
2,320,000
Answer:
2,320,000
Step-by-step explanation:
You have to subtract the 10,000,000 by the amount that has already been sold in order to find out the difference on how many copies are left in order to receive an award.
10,000,000 - 7,680,000 = 2,320,000

Answer:
(a) 6 °C
(b) -3.7 °C
(c) the y-intercept is (0, 10); the x-intercept is (10, 0)
Step-by-step explanation:
(a) The graph tells you the wind chill is 6 °C when the wind speed is 4 m/s.
__
(b) The annotated point on the graph tells you the wind chill is -3.7 °C when the wind speed is 20 m/s.
__
(c) The intercepts are marked on the graph. The y-intercept is (0, 10); the x-intercept is (10, 0). These represent the temperature when the wind speed is 0, and the wind speed when the temperature is 0, respectively.

3x-29=6x-7 what is x
Answer:
Step-by-step explanation:
You want to get x on one side and the constants on the other. First subtract both sides by 3x to get:
-29 = 3x - 7
Now add 7 to both sides to get:
-22 = 3x
Divide each side by 3 to get:
x = -22/3

What is the Desmos Graphing App for Algebra and how do you use it. Is it a computer thing or do you download it on your phone?
Answer:
see below
Step-by-step explanation:
The Desmos graphing utility is available as an app for phone or tablet from the app stores for Android and Apple devices. It is available from the desmos web site by clicking on "Graphing Calculator" on the home page.
Attached is a screen-shot of the web version. Help can be found under the (?) button at upper right. I found the help to be useful when first starting or when trying to do something I haven't done before.
You can create an account, if you like, but that is not necessary to obtain all of the basic functionality.
A link for sharing a graph will be generated by clicking on the icon to its left. Graphs can also be saved for later reference, if you have an account. The link to a graph will work whether you have an account or not.
__
There are other desmos tools available, too, for general calculation, geometrical construction, and matrix manipulation. (I have not yet used those.)
_____
Desmos likes to use x and y for the independent and dependent variables, respectively. You can define something like h(t) = 5t+1 and it will graph it as though it were y=5x+1. When you click on an equation or graph, points of intersection with other graphs or with the axes will be highlighted. Clicking on those highlights will give their coordinates.
Equations don't need to be of the "y=" form. For example, you can use x^2+y^2=1 to make a unit circle. The usual math symbols work for keyboard input (* for multiplication; / for division; ^ for exponents). The tab or arrow keys move out of denominator or exponent fields. To make more complicated exponents, parentheses help.
There's so much more it can do. It is worthwhile to visit the on-line tutorial information.

A survey of radio stations was conducted following the attacks on the World Trade Center in 2001. One of the variables recorded was the region in which the station was located (east, center, or west). In addition to the variable "region," the following information was collected: the quartile of the media market (top, second, third, and fourth), state, rank (a number between 1 and 205), and share (a number between 0 and 7). The modified boxplot of station ranks above identifies how many outliers?
