Given :
Rosa is putting carpet in her room. She’s using the scale 1 inch = 3 ft .
In the drawing, the length is 5.5 inches and the width is 3.25 inches. If carpet costs 2.58 per square foot.
To Find :
How much will it cost to carpet the bedroom.
Solution :
Length of bedroom , l = 5.5 × 3 = 16.5 ft.
Width of bedroom , w = 3.25 × 3 = 9.75 ft.
SO, area of bed room is :
\(A=l\times w\\\\A=16.5\times 9.75\ ft^2\\\\A=160.875\ ft^2\)
Now, cost to carpet the bedroom is :
\(C=2.58\times A\\\\C=2.58\times 160.875\\\\C=415.0575\)
Hence, this is the required solution.

Hi can any one teach me this constant difference
Answers
The constant differences between the consecutive terms are 2 (a); 2 (b), -3 (c), 7 (d), 1(e), and 6(f).
How do you find the constant difference in a sequence of numbers?In math, the constant difference can be defined as the number that defines the pattern of a sequence of numbers. This means that number that should be added or subtracted to continue with the sequence.
Due to this, to determine the constant difference it is important to observe the pattern and find out the number that should be added. For example, if the sequence is 2, 4, 6, 8, there is a difference of 2 between each of the numbers and this is the constant difference.

Given SSxx is 950 and SSxy is 205.2. Calculate and interpret the value of r if the data
consist if 12 number of samples with y = 120 and Σy² = 2028
Answers
Step-by-step explanation:
To calculate the correlation coefficient (r) given SSxx, SSxy, and other information, we need to use the following formula:
r = √(SSxy / SSxx)
Given SSxx = 950 and SSxy = 205.2, we can substitute these values into the formula:
r = √(205.2 / 950)
Calculating the value:
r = √(0.216)
r ≈ 0.465
The correlation coefficient (r) is approximately 0.465.
Interpretation: The correlation coefficient measures the strength and direction of the linear relationship between two variables. In this case, the value of r = 0.465 indicates a positive linear relationship between the variables, but it's not a strong relationship. The closer the value of r is to 1 or -1, the stronger the relationship. Since r = 0.465 is relatively close to zero, it suggests a weak positive linear association between the variables being an analyzed.

The Pearson's correlation coefficient (r) based on given data is approximately 0.44, implying a moderate positive correlation.
Explanation:The formula for calculating Pearson's correlation coefficient (r) in this case is given as: r = SSxy / sqrt(SSxx * SSyy). However, we don't have the value for SSyy directly, but we can calculate it. We know that SSyy = Σy² -(Σy)² / n. Given that Σy² is 2028 and Σy is 120 and number of samples n is 12, we can calculate SSyy as: SSyy = 2028 - (120)² / 12 = 52. Now, substitute SSxx = 950, SSxy = 205.2 and SSyy = 52 in the formula to find r: r = 205.2 / sqrt(950 * 52), giving us an r-value of approximately 0.44. This value of r suggests a moderate positive correlation between the variables in the dataset.

To get $600 after 4 years at 7% compounded monthly
Answers
The required present value needed now to get $700 after 4 years at 11% compounded monthly is $451.73.
To find the present value of $600 after 4 years at 7% compounded monthly, we can use the formula for compound interest:
Compound Interest =P(1+r/n)^rt
Substituting the given values, we get:
Compound Interest =600 (1+7/n)^4
Simplifying this equation, we get
P = 600 / 1.487
P = 451.73
Therefore, the present value needed now to get $600 after 4 years at 7% compounded monthly is $451.73.

Mr. Han is trying to decide how many new copies of a book to order for his students each book weighs 6 ounces which ordered pair is a variable solution if X represents the number of books he ordered and Y represents the total weight of the book in ounces
Answers
Options : (–3, –18) (–0.5, –3) (0, 0) (0.5, 3)
Answer: (0, 0)
Step-by-step explanation:
Given the following :
X = Number of books he ordered
Y = total weight of the book in ounces
Weight of each book = 6 ounces.
From the options provided,
(–3, –18) (–0.5, –3) (0.5, 3) aren't feasible options because of the following reasons.
The number of books ordered must be a whole number as it is impossible to order fraction of a book, hence, the ordered pair, (-0.5, - 3) and (0.5, 3) aren't viable solutions.
Also, the option (–3, –18) portrays a negative value and the number of books a person orders cannot be negative. Hence, the viable solution should be a positive whole number.
The only solution which seems viable is (0, 0) with x being 0 and y also. 0
If x = Number of books he ordered = 0
Ultimately, the total weight of the book in ounces will be (weight per book * number of books ordered)
= (6 ounces × 0) = 0
Hence, (0,0)

square feet. How many bags will she need to cover the garden?
Answers
Answer:
4 bags
Step-by-step explanation:
The number of required bags can be found by dividing the coverage required by the coverage per bag.
AreaThe area of Lisa's garden is given by the formula ...
A = LW
For the given dimensions, the area is ...
A = (12 ft)(10 ft) = 120 ft²
BagsThe number of required bags can be found by dividing the area by the area per bag:
(120 ft²)/(30 ft²/bag) = 4 bags
Lisa will need 4 bags of fertilizer to cover the garden.

occurred. The store is 30 feet long and 20 feet wide. How much tape
is needed?
Answers
100 feet of caution tape is required for the store.
Given that a police officer must run caution tape around a store where a crime occurred. The store is 30 feet long and 20 feet wide and asked to find the tape required for the store.
According to given measurements, we assume the store be in rectangular shape .To find the tape required, calculate the perimeter of the rectangle.
Perimeter of the rectangle=2 ( length + width )
Given length = 30 feet and width = 20 feet
Perimeter of the rectangle = 2 ( 30 feet + 20 feet )
Perimeter of the rectangle = 2 ( 50 feet )
Perimeter of the rectangle = 100 feet
Therefore 100 feet of caution tape is required for the store.
Hence , caution tape of 100 feet is required for the store.

Consider a circle whose equation is x2 + y2 – 2x – 8 = 0. Which statements are true? Select three options.
The radius of the circle is 3 units.
The center of the circle lies on the x-axis.
The center of the circle lies on the y-axis.
The standard form of the equation is (x – 1)² + y² = 3.
The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
Answers
The three statements that are true include the following:
A. The radius of the circle is 3 units.
B. The center of the circle lies on the x-axis.
D. The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
What is the equation of a circle?In Mathematics, the standard form of the equation of a circle is represented by this mathematical expression;
(x - h)² + (y - k)² = r² .......equation 1.
Where:
h and k represents the coordinates at the center of a circle.
r represents the radius of a circle.
Based on the information provided, we have the following equation of a circle:
x² + y² – 2x – 8 = 0 ......equation 2.
In order to determine the true statements, we would rewrite the equation in standard form and then factorize by using completing the square method:
x² – 2x + y² = 8 = 0
x² – 2x + (2/2)² + y² = 8 + (2/2)²
x² – 2x + 1 + y² = 8 + 1
(x – 1)² + (y - 0)² = 9 .......equation 3.
By comparing equation 1 and equation 3, we have the following:
Center (h, k) = (1, 0)
Radius (r) = 3
Additionally, this line and the center of the given circle lies on the x-axis (x-coordinate) because the y-value is equal to zero (0).
(x - 0)² + (y - 0)² = 3²
x² + y² = 9.

If the tip varies directly with the number of guests, which equation represents the relationship between the tip, t, and the number of guests, g?
t = 1.8g
t = t equals StartFraction g Over 18 EndFraction.
g = 1.8t
g = g equals StartFraction t Over 18 EndFraction.
Answers
Answer: t = 1.8g
Step-by-step explanation:
Since we are given the information that the tip varies directly with the number of guests, then the formula to use will be:
t = kg
where,
t = wait staff tip
g = number of guests
Therefore, when the number of guests is 10 and the tip is $18, the constant of proportionality will be:
t = kg
18 = 10k
k = 18/10
k = 1.8
Therefore, t = 1.8g
