The data set below has 6 values.
Find the mean absolute deviation for the data set.
If necessary, round your answer to the nearest hundredth.
8, 6, 6, 18, 17, 11
Calculate the mean of the data set, find the absolute deviation of each data point, and then average those deviations. For this data set, the mean absolute deviation is 4.33.
Explanation:To start off with, the mean absolute deviation is a measure of the dispersion or spread that represents the average difference between the values of the data set and the mean (average).
First, add up all the numbers of the data set. So, 8 + 6 + 6 + 18 + 17 + 11 = 66. Then divide this sum by the number of values (6) to calculate the mean (average). So, 66 ÷ 6 = 11.
Next, find the absolute deviation of each number in the set by subtracting the mean from each number and taking absolute value: |8-11|, |6-11|, |6-11|, |18-11|, |17-11|, |11-11|. This gives us: 3, 5, 5, 7, 6, 0.
Add these absolute deviations: 3 + 5 + 5 + 7 + 6 + 0 = 26. Then divide it by the count of the numbers in the data set (6). So, 26 ÷ 6 = 4.33, which is your mean absolute deviation to two decimal places.

Final answer:
To find the mean absolute deviation for the data set 8, 6, 6, 18, 17, 11, you first calculate the mean of these numbers, then find the absolute deviations from this mean, and finally calculate the mean of those absolute deviations, which is approximately 4.33.
Explanation:
The student is asking how to find the mean absolute deviation (MAD) for a data set. The data set provided is 8, 6, 6, 18, 17, 11. To calculate the MAD, we first need to find the mean of the data set, then calculate the absolute deviation of each data value from the mean, and finally find the average of those absolute deviations.
Calculate the mean of the data set: (8 + 6 + 6 + 18 + 17 + 11) / 6 = 66 / 6 = 11.
Find the absolute deviation of each data value from the mean: |8 - 11| = 3, |6 - 11| = 5, |6 - 11| = 5, |18 - 11| = 7, |17 - 11| = 6, |11 - 11| = 0.
Calculate the mean of these absolute deviations: (3 + 5 + 5 + 7 + 6 + 0) / 6 = 26 / 6 = 4.33.
Hence, the mean absolute deviation for this data set is approximately 4.33.

You want to take group fitness classes at a nearby gym, but needs to start by selecting a membership plan. With the first membership plan, you can pay $20 per month, plus a $60 signing fee. With the second membership plan, you can pay $40 per month plus no signing fee. At what number of months will both plans cost the same amount?
Answer:
after 3 months, both plans cost the same amount
Step-by-step explanation:
Let x is the number of monthsLet y is the total costGiven the following information:
Plan 1: pay $20 per month, plus a $60 signing fee
=> the equation for this plan is:
y1 = 20x+60
Plan 2: pay $40 per month plus no signing fee
=> the equation for this plan is:
y2 = 40x
To find number of months will both plans cost the same amount, we need to set the equation of plan 1 = equation of plan 2
<=> y1 = y2
<=> 20x+60 = 40x
<=> 20x = 60
<=> x = 3
So after 3 months, both plans cost the same amount
The length of a field, 1.2 km long is represented on a map by a line 40mm long. What is the scale of the map
Final answer:
The scale of the map is 1:30,000.
Explanation:
The scale of a map represents the relationship between the distance on the map and the corresponding distance on the Earth's surface. To find the scale of the map, we need to determine the ratio between the length of the field on the map and its actual length. In this case, the length of the field is 1.2 km, which is represented on the map by a line that is 40 mm long.
To calculate the scale, we can use the formula:
Scale = Actual length on the ground / Length on the map
Substituting the values, we get:
Scale = 1.2 km / 40 mm
First, we need to convert the length on the map to the same unit as the actual length. Since 1 km = 1,000,000 mm, we can convert mm to km by multiplying by 1/1,000,000:
Length on the map in km = 40 mm × (1 km / 1,000,000 mm) = 0.00004 km
Now we can calculate the scale:
Scale = 1.2 km / 0.00004 km = 30,000
Therefore, the scale of the map is 1:30,000.

Circletown's limits form a perfectly circular shape. It has a population of 20{,}00020,00020, comma, 000 and a population density of 480480480 people per square kilometer.
What is Circletown's radius?
Answer:
3.64
Step-by-step explanation:
Based on the calculations, the radius of Circletown is equal to 3.64 kilometer.
Given the following data:
Total population = 20,000.Population density = 480.How to calculate Circletown's radius?First of all, we would determine the area of Circletown by dividing the total population by its population density as follows:
Area = 20,000/480
Area = 41.67 square kilometer.
Mathematically, the area of a circle is calculated by using this formula:
Area = πr²
Where:
r is the radius of a circle.
Substituting the given parameters into the formula, we have;
41.67 = 3.142 × r²
r² = 41.67/3.142
r = √13.26
r = 3.64 kilometer.

Use slope or the distance formula to determine the most precise name for the figure A(-1,-4) B(-1,-1) C(4,1) D(2,-2)
a) kite
b)trapezoid
c)sqaure
d)rhombus
Final answer:
After calculating distances between each pair of points and evaluating the properties of the resulting figure, it has been determined that the most precise name for the figure is a kite. This is due to the specific lengths of its sides and diagonals and their relationship to one another, which fits the definition of a kite.
Explanation:
To determine the most precise name for the figure formed by points A(-1,-4), B(-1,-1), C(4,1), and D(2,-2), we need to calculate the distances between each pair of points (sides of the figure) and evaluate their slopes where applicable.
AB = √(((-1)-(-1))^2 + ((-1)-(-4))^2) = 3
BC = √((4-(-1))^2 + (1-(-1))^2) = √(25 + 4) = √29
CD = √((4-2)^2 + (1-(-2))^2) = √(4 + 9) = √13
DA = √((2-(-1))^2 + ((-2)-(-4))^2) = √(9 + 4) = √13
AC (diagonal) = √((4-(-1))^2 + (1-(-4))^2) = √(25 + 25) = √50
BD (diagonal) = √((2-(-1))^2 + ((-2)-(-1))^2) = √(9 + 1) = √10
With sides AB and CD equal and AD and BC equal, and none of the sides being equal to each other, and considering two unequal diagonals, we can conclude that this figure is a kite, given that a kite has two pairs of adjacent sides that are equal but not all sides are equal and the diagonals are of different lengths.

Jesse and Amir were assigned the same book to read. Jesse started reading on Saturday, and he is reading 30 pages a day. Amir didn't start until Sunday, but he is reading 35 pages a day.
How many days will it take Amir to catch up to Jesse, and how many pages will they each have read?
Answer the questions to solve this problem using a system of equations.
1. Write an equation to represent the number of pages Amir has read. Use x to represent the number of days Amir has been reading and y to represent the number of pages he has read.
Answer:
6 days
210 pages
Step-by-step explanation:
As stipulated by the question, let the number of days Amir has been reading be x and the number of pages he had read to be y.
Now since he reads 35 pages per day.
Then mathematically;
y = 35x
For Jesse, He started reading a day before, this means that the number of days he had read would be x + 1. Since he reads 30 per day, the total number of pages he would have read is 30(x+1)
To find the number of days which is x, we have to assume that at a point in time, the number of books they would have read would be the same meaning that
Also; y = 30(x + 1)
Equating the two situations
35x = 30(x + 1)
35x = 30x + 30
35x -30x = 30
5x = 30
x = 30/5
x = 6 days
This means that it will take Amir 6 days to catch Jese.
The number of books they would have read by then is y = 35x = 30(x + 1)
= 35 * 6 or 30(6+1)
= 210
The total number of pages that he read will be 210 pages.
Based on the equation given, the equation to represent Amir's information will be:
y = 35 × x
y = 35x
Jesse's equation will be:
y = 30(x + 1)
Then, we'll equate both equations together. This will be:
35x = 30(x + 1)
35x = 30x + 30
35x - 30x = 30
5x = 30
x = 30/5
x = 6
Therefore, the number of pages read will be:
y = 35x
y = 35 × 6
y = 210 pages.

Which system of equations has an infinite number of solutions?
A. 2x – 6y = 18
x – y = 9
B. 2x – 6y = 18
x + 3y = 9
C. 2x – 6y = 18
x – 3y = 9
Answer:
we choose C
Step-by-step explanation:
We need to understand an infinite number of solutions happens when all numbers are solutions. This situation means that there is no one solution.
So let analyse 3 options:
A.
2x – 6y = 18 (1) x – y = 9 <=> y = x -9 (2)Substitute (2) in (1) we have:
2x – 6(x - 9) = 18
<=> -4x + 54 = 18
<=> x = 9
=> y = 0
There is only 1 solution => A is wrong
B.
2x – 6y = 18 <=> x = 9 + 3y (1) x + 3y = 9 (2)Substitute (1) in (2) we have:
(9+ 3y) + 3y = 9
<=> 3y = 0
<=> y = 0
=> x = 9
There is only 1 solution => B is wrong
C.
2x – 6y = 18 (1)
x – 3y = 9 <=> x = 9+ 3y (2)
Substitute (2) in (1) we have:
2(9+3y) - 6y = 18
<=> 18 + 6y - 6y = 18
<=> 18=18
Yes, this system of equations has an infinite number of solutions
So we choose C
Final answer:
The system of equations with an infinite number of solutions is when one equation is a multiple of the other, which results in the same line and infinite solutions.
Explanation:
The system of equations that has an infinite number of solutions is:
A. 2x – 6y = 18
x – y = 9
To determine this, we notice that the second equation x - y = 9 is a multiple of the first equation 2x - 6y = 18. Since one equation is a multiple of the other, these equations represent the same line, leading to an infinite number of solutions.
