What is the function rule?Function rule is the rule of writing the relationship between the two variables, one is dependent and another is independent.
The table given in the problem is;
Input (x) -6 -1 1
Output (y)
We have given the equation as;
y = 0.2x – 2
Complete the table using the above function rule;
At (x) equal to -6,
y = 0.2x – 2
y = 0.2(-6) – 2
y = -3.2
At (x) equal to -1,
y = 0.2x – 2
y = 0.2(-1) – 2
y = -2.2
At (x) equal to 1,
y = 0.2x – 2
y = 0.2(1) – 2
y = -1.8
Hence,
Input (x) -6 -1 1
Output (y) -3.2 -2.2 -1.8

What is the median of the data set? 9, 3, 10, 12, 4, 5, 12, 2 enter your answer in the box.
Answers
The median of the given standard data set 9, 3, 10, 12, 4, 5, 12, 2 will be calculated approximately to 7. So , the median of the dataset is 7.
The median is a measure of central tendency that gives us an idea of where the "middle" of a data set lies. In other words, it gives us a value that separates the data set into two equal parts, with half of the values being above the median and the other half being below the median.
To find the median of a data set, the first step is to arrange the values in ascending or descending order. This makes it easier to identify the middle value(s) in the data set.
If the data set has an odd number of values, then there is a single middle value and that value is the median. For example, if we have the data set: 1, 2, 3, 4, 5, the median would be 3 because it is the middle value in the ordered set.
If the data set has an even number of values, then there are two middle values and the median is the average of those two values. For example, if we have the data set: 1, 2, 3, 4, 5, 6, the median would be the average of 3 and 4, which is (3 + 4) / 2 = 3.5.
So, in the case of the data set: 9, 3, 10, 12, 4, 5, 12, 2, we arrange the values in ascending order: 2, 3, 4, 5, 9, 10, 12, 12. Since there are 8 values, which is an even number, there are two middle values: 5 and 9. The median is the average of these two values, which is (5 + 9) / 2 = 7.

Surface area
The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Area = length x breadth
To find the surface area of the postal box, we first find the area of each sides of the box and add them together.
Top and bottom area = L x B = 12 x 8 = 96inches² x 2 = 192inches²
Front and back areas = L x B = 12 x 2 = 24inches² x 2 = 48inches²
Area of the sides = L x B = 8 x 2 = 16inches² x 2 = 32inches²
Total surface area will be 192 + 48 + 32 = 272inches²

The factored form of the quadratic equation is given as follows:
y = 3(x + 0.6667)(x - 6).
How to obtain the factored form of the quadratic equation?The quadratic equation for this problem is defined as follows:
3x² - 16x - 7 = 5.
3x² - 16x - 12 = 0.
The coefficients are given as follows:
a = 3, b = -16, c = -12.
Hence the discriminant is of:
D = (-16)² - 4(3)(-12)
D = 400.
Then the roots are of:
x = (16 - sqrt(400))/6 = -0.6667.x = (16 + sqrt(400))/6 = 6.Considering the leading coefficient of 3 and the roots, the factored form of the equation is given as follows:

Suppose the account in #3 above paid interest quarterly instead of annually. Find the account balance after 5 years.
Answers
The account with compound interest of 7.2 % quarterly after 5 years is given by A = $ 1,428.75
What is Compound Interest?Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.
The formula for calculating Compound Interest is
A = P ( 1 + r/n )ⁿᵇ
where A = Final Amount
P = Principal
r = rate of interest
n = number of times interest is applied
b = number of time periods elapsed
Given data ,
Let the amount after compound interest be represented as A
Now , the equation will be
The initial principal amount = $ 1000
The rate of interest r = 7.2 %
The number of times interest is applied n = 4 ( quarterly )
The number of years b = 5 years
A = P ( 1 + r/n )ⁿᵇ
Substituting the values in the equation , we get
A = 1000 ( 1 + 0.072/4 )⁴ˣ⁵
On simplifying the equation , we get
A = 1000 ( 1 + 0.018 )²⁰
On further simplification , we get
A = 1000 ( 1.018 )²⁰
A = $ 1,428.75
Hence , the amount after 5 years is $ 1,428.75

Answers
Bob continues his research because even though there is no linear equation relationship between the number of bedrooms and selling price, there could be another type of relationship.
Bob continues his research because even though the correlation value he calculated between the number of bedrooms and the selling price was only 0.05, this does not necessarily mean that there is no relationship of any kind between these two variables. It simply means that there is no linear relationship between the two. There could still be other types of relationships between the two variables, such as an exponential or quadratic relationship. It is possible that further analysis and exploration of the data set would reveal such a relationship and allow Bob to uncover the relationship between the two variables. Additionally, even if the correlation value is low, it does not necessarily mean that there is no relationship between the two variables. It simply means that the relationship is weak. Therefore, Bob should continue his research in order to uncover any potential relationships between the number of bedrooms and selling price.

Which equation represents a proportional relationship?
A. y = 4x+1
B. y = 5x²
C. y=9
Answers
B. y = 5x² represents a proportional relationship.
In a proportional relationship, the ratio of the dependent variable (y) to the independent variable (x) is constant. In this equation, as x increases, y also increases by a constant factor (5 times x). This indicates that the two variables are proportional to each other.
In A. y = 4x + 1 and C. y = 9, there is no constant ratio between y and x, so they do not represent proportional relationships.
Hal sold a box of 30 books at a yard sale for a total of $62.16. He sold the paperback books for $1.78 each and sold the hardcover books for $2.51 each.
Which system of equations can be used to determine the number of $1.78 paperback books, x, and the number of $2.51 hardcover books, y, that were
sold at the yard sale?
Answers
Answer:
Step-by-step explanation:
Let x be the number of $1.78 paperback books and y be the number of $2.51 hardcover books that were sold. The total number of books is x + y = 30 and the total amount of money earned is $62.16. The cost of the paperback books is x * $1.78 and the cost of the hardcover books is y * $2.51.
So, we have the following system of equations:
x + y = 30 (the total number of books is 30)
x * $1.78 + y * $2.51 = $62.16 (the total amount of money earned is $62.16)
This system of equations can be used to determine the number of $1.78 paperback books and the number of $2.51 hardcover books that were sold at the yard sale.

(a) The final amount in a compound interest is,
A = P(1 + [tex]\frac{r}{n}[/tex] )^ (nt), where,
A : Final amount
P : Principal amount
r : Rate of interest
t : Time in years
n : number of times compounded in a year
Given A = $1500, P = $1000, r = 0.05, n = 1
The equation is,
1500 = 1000 (1 + 0.05)^t
(b) 1500 = 1000 (1 + 0.05)^t
1500 / 1000 = (1.05)^t
1.5 = (1.05)^t
Taking logarithm on both sides,
㏒ (1.5) = t ㏒ (1.05) [since ㏒ (a)ᵇ = b ㏒ (a)]

Answers
Answer:
We can use the proportion:
48 pages / x = 80% / 100%
where x is the required length of the paper in pages.
First, we can simplify the right-hand side of the equation:
80% / 100% = 0.8
Next, we can solve for x by cross-multiplying:
48 pages / 0.8 = x
x = 60 pages
Therefore, the required length of the paper is 60 pages
