A group of students was asked, "How many hours did you watch television last week?" Here are their responses: 7, 5, 16, 20, 17, 9, 18, 15. Find the Mean Absolute Deviation (M.A.D.) for these students.
Answer:
4.78125
Step-by-step explanation:
Step 1
Find the mean
Mean = Sum of Terms/Number of Terms
Mean = 7+5+ 16+20+ 17+ 9+ 18+ 15/8
= 107/8
= 13.375
Step 2
Find the Mean Absolute Deviation
Mean Absolute Deviation formula = |x - Mean|/n
Mean Absolute Deviation =[ |7 - 13.375| +| 5 -13.375|+ |16 - 13.375| + |20 - 13.375| +| 17 - 13.375| + |9 - 13.375 | +| 18 -13.375|+|15 - 13.375|] /8
Mean Absolute Deviation = 4.78125
Therefore, the Mean Absolute Deviation (M.A.D.) for these students = 4.78125
Mary wants to put a fence around her garden. The garden measures 10 feet by 6 feet. If fencing costs $5 per foot, how much will the fence cost Mary?
First, find the cost of how much fence Mary needs per side.
10 * 5 = 50
10 * 5 = 50
6 * 5 = 30
6 * 5 = 30
Second, add all together.
50 + 50 + 30 + 30 = 160
Therefore, the total cost of the fence will be $160.
Best of Luck!

In the xy-plane, the graph of which of the following linear has a negative x-intercept?
Answer:
[tex]\Large \boxed{\mathrm{E}}[/tex]
Step-by-step explanation:
The x-intercept is when y = 0.
[tex]y = 3x + 1[/tex]
Let y = 0.
[tex]0=3x+1[/tex]
Subtracting 1 from both sides.
[tex]-1=3x[/tex]
Dividing both sides by 3.
[tex]\frac{-1}{3} =x[/tex]
The x-intercept is negative.

[tex] \huge{ \underline{ \underline{ \gray{ \bf{Solution:}}}}}[/tex]
Let,
Mass of the steel be 108xMass of the copper be 7xThen, Total mass = 108x + 7x = 115xGiven,
Total mass of the coin = 230 mgThat means,
⇛ Total mass of the coin = 230 mg
⇛ 115x = 230 mg
⇛ x = 230 mg/115
⇛ x = 2 mg
Then,
Mass of the steel = 108(2) = 216 mgMass of the copper = 7(2) = 14 mg☁️ ANSWER - 14 mg (Mass of copper)

In a test (+5)marks are give for every correct answer and (-2)marks for every incorrect answer. Jay answered all questions and scored (-12)m though he got four correct answer)how many incorrect answer he attempted
Answer:
32 incorrect answers was attempted by JayStep-by-step explanation:
Let the amount of correct answer gotten be x and that of wrong answer be y. The sum of Jay score = 5x+ (-2)y [since(+5)marks are give for every correct answer and (-2)marks for every incorrect answer]
If Jay answered all questions and scored (-12)m, then 5x - 2y = -12
If Jay got four answers correctly, the number of correct answers x = 4
Substituting x = 4 into the equation 5x - 2y = -12 to get the value of y, we will have;
5(4) - 2y = -12
20 - 2y = -12
-2y = -12-20
-2y = -32
y = 16
This means that Jay attempted 16 incorrect answers.

The mixed number [tex]2\frac{7}{12}[/tex] as a decimal is approximately 2.58333 as per th rule of simplification.
To simplify [tex]2\frac{7}{12}[/tex] as a decimal form, we need to convert the mixed number to an improper fraction and then perform the division.
First, multiply the whole number (2) by the denominator of the fraction (12), and add the numerator (7). This gives us 2 x 12 + 7 = 24 + 7 = 31.
Now, the numerator of the improper fraction is 31, and the denominator remains the same (12). Therefore, the improper fraction is 31/12.
To convert this improper fraction to decimal form, divide the numerator (31) by the denominator (12):
31 ÷ 12 = 2.58333 (rounded to five decimal places)
Hence, [tex]2\frac{7}{12}[/tex] as a decimal is approximately 2.58333.
It's important to note that the decimal form is an approximation because fractions can have repeating decimal representations. In this case, [tex]2\frac{7}{12}[/tex] can be expressed exactly as a fraction but has a repeating decimal approximation when converted to decimal form.

1. Rick renovated his home. He made his bedroom 40% larger (length and width) than its original size. If the original dimensions were 144 inches by 168 inches, how big is his room now if measured in feet?
Answer:
New dimension: 16.8 feet by 19.6 feet.
Step-by-step explanation:
Given that,
The original dimensions of the room were 144 inches by 168 inches. Rick renovated his home. He made his bedroom 40% larger than its original size.
40% of 144 = 57.6
New length is 144 + 57.6 = 201.6 inches
40 % of 168 = 67.2
New breadth is 168 + 67.2 = 235.2 inches
Since, 1 foot = 12 inch
201.6 inches = 16.8 feet
235.2 inches = 19.6 feet
The new dimension of the room is 16.8 feet by 19.6 feet.

The yearly cost in dollars, y, for a member at a video game arcade based on total game tokens purchased, x, is y =y equals StartFraction 1 Over 10 EndFraction x plus 60.X + 60. A nonmember pays $0.20 per game token, but no yearly fee. Which equation represents the yearly cost for a nonmember at the same video game arcade based on the total number of game tokens purchased in a year?
Answer:
[tex]y = \frac{1}{5}x[/tex]
Step-by-step explanation:
Given
Yearly Cost for members; [tex]y = \frac{1}{10}x + 6[/tex]
Required
Determine the yearly cost for non members
From the question, we understand that:
A non member pays $0.20 for each game;
Yearly cost is then calculated as thus;
y = Amount * Number of Games
Where:
Amount = $0.2 and Number of Games = x
[tex]y = 0.20 * x[/tex]
Convert 0.2 to fraction
[tex]y = \frac{2}{10} * x[/tex]
Divide the numerator and the denominator by 2
[tex]y = \frac{1}{5} * x[/tex]
[tex]y = \frac{1}{5}x[/tex]
Hence, the yearly cost for non members is
[tex]y = \frac{1}{5}x[/tex]

A group of objects or numbers is called a A part of a set is called a
Answer:
Set; subset.
Step-by-step explanation:
A group of objects or numbers is called a set while a part of a set is called a subset. The objects or numbers that make up a set are generally referred to as elements or members and are written inside a pair of curly braces {}.
A set can be made up of elements such as numbers, alphabets, people, cars etc.
For instance, Set A = {2, 4, 6, 8, 10, 12} represents all the even number between 1 - 12.
On the other hand, a subset is a part of a larger set.
For instance, comedy movies, horror movies, romance movies, action movies are a subset of movies.
