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.

Here's how I got my answer:

Do each equation carefully and be sure to pay attention to the order of the multiplication, subtraction, addition, parentheses and division signs. Since B. is just the Associative Property (it means that it has been grouped in a different way) then it is the same as the first equation.

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]

Answer:

y = y equals 1 Over 5 x. x

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

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!

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.

Answer:

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 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.

Answer:

Step-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.

Answer:

x > 0 and y > 0
