A pavement 4m wide is constructed along the outer side of the boundary of a square shaped ground having it's side of 13m length. The cost of levelling the pavement at the rate of Rs 1.25 per square meter is Rs 340.
As per given information,
Side of a square shaped ground = 13 m
Width of pavement constructed = 4 m
We need to find the cost of levelling the pavement at the rate of Rs 1.25 per square meter.
Area of the square shaped ground = Side × Side= 13 × 13= 169 sq.m
Area of the square shaped ground along with pavement constructed
= (13 + 8) × (13 + 8)
= 21 × 21
= 441 sq.m
Area of the pavement constructed
= Area of the square-shaped ground along with pavement constructed - Area of the square shaped ground
= 441 - 169
= 272 sq.m
Cost of levelling 1 sq.m of pavement = Rs 1.25
Cost of levelling 272 sq.m of pavement = 272 × Rs 1.25 = Rs 340

The bball3 dataset appears to take the form of panel data, which is a type of longitudinal data consisting of multiple observations of the same individuals over time
The bball3 dataset appears to take the form of panel data. Panel data is a type of longitudinal data where observations are made on the same individuals over time. This means that the dataset likely consists of multiple observations of a set of individuals, with the observations collected at different points in time. In a panel data set, each individual can be referred to as a ‘panel unit’.
Cross-sectional data, on the other hand, consists of observations that are collected only once, at a single point in time. This means that each observation consists of a snapshot of the population at a given moment, which is different from panel data where each observation may represent different points in time for the same individuals.
Time series data is a type of data that is collected over a period of time. It captures how a certain variable changes over time, and is often used for forecasting purposes. This is different from panel data, which captures information about the same individuals at different points in time.
In conclusion, the bball3 dataset appears to take the form of panel data, which is a type of longitudinal data consisting of multiple observations of the same individuals over time. It is not cross-sectional or time series data.

in a survey, 130 out of 250 students said that they played video games. what percent of the students played video games? answer
The percentage of students who played video games in the survey is 52%.
To find this percentage, we first need to calculate the fraction of students who played video games. This can be done by dividing the number of students who played video games by the total number of students surveyed:
Fraction of students who played video games = 130/250
Simplifying this fraction by dividing both the numerator and denominator by 10, we get:
Fraction of students who played video games = 13/25
To convert this fraction to a percentage, we can multiply it by 100:
Percentage of students who played video games = (13/25) * 100
Simplifying this expression, we get:
Percentage of students who played video games = 52%
Therefore, 52% of the students in the survey played video games.
Hence, to find the percentage of students who played video games in a survey, we divide the number of students who played video games by the total number of students surveyed and then multiply the resulting fraction by 100 to get the percentage.

Which point is not included in the solution set for the inequality? (–2, 1) (1, 3) (4, 3) (5, -1?
From the given graph, the points (1, 3) lies on dotted lines, thus they are not taken in the solution set for the inequality.
Explain about the solution set of inequality?When expressions are compared using the operators "less than" (<), "less than or equal to" (<=), "greater than" (>), or "greater than or equal to" (>=), an inequality is created.
A number is a solution to an inequality in x if it can be used to replace x with a statement that is true. The collection of all solutions makes up the solution set for an inequality. Usually, there are infinitely many solutions to an inequality, and interval notation makes it simple to describe the solution set.From the graph, the shaded region shows the solution for the inequality.
As we can see that the curve is drawn with the broken lines,the points lying on the curve will no be taken as in solution set of inequality.

The waiting times for the train are known to follow a uniform distrbution Find the 60th percentile for the waiting times (in minutes). Additional Qa Section 5.1
The sky Train from the terminal to the Cental car and long-term parking center is supposed to arrive every 6 minutes. The waiting times for the train are known to follow a uniform distribution. The 60th percentile of the waiting times is 3 minutes.
Using the formula, `P(X≤x) = Percentile, where `X` is the random variable whose percentile is required, and `x` is the value at which the percentile is required.
Given that the waiting times for the train follow a uniform distribution, the probability density function of the uniform distribution is given as: `f(x) = 1/(b-a)` , where `a` and `b` are the lower and upper limits of the distribution.
Now, it is given that the sky train is supposed to arrive every 6 minutes. This means that the minimum and maximum times for waiting will be 0 and 6 minutes, respectively. Hence, `a = 0` and `b = 6`.
Using the formula for the uniform distribution, we have `f(x) = 1/(6 - 0) = 1/6`. Therefore, the cumulative distribution function (CDF) is given by: `F(x) = ∫f(x) dx = (1/6) * ∫dx = x/6.
`Using the formula to find the 60th percentile of the waiting times: `P(X≤x) = Percentile`, we have: `0.6 = P(X≤x)`. Therefore, the value of `x` at which the 60th percentile of the waiting times is achieved is: `x = 0.6 * (b - a) + a = 0.6 * (6 - 0) + 0 = 3`. Thus, the 60th percentile of the waiting times is 3 minutes.

Option 2: Fixed rate loan at 3% for 20 years, with fixed monthly payments of $9,705.46
How much money does the property investor save by choosing the balloon mortgage?
A spreadsheet was used to calculate the correct answer.Your answer may vary slightly depending on the technology used.

Answer:
The savings for the property investor would be $63,750 - $63,011.23 = $738.77, which is the answer to option B, $340,329.83.
Step-by-step explanation:
What is the interest?
Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.
To calculate the savings, we need to calculate the total amount of interest paid over the life of the loan for both options, and then subtract the smaller amount from the larger amount.
For the fixed-rate loan, the total amount of interest paid can be calculated by multiplying the interest rate by the loan amount and dividing it by the number of payments over the life of the loan:
$1,750,000 * 3% / (12 * 20) = $63,750
The total amount of interest paid over the life of the loan for the fixed-rate loan would be $63,750.
For the balloon mortgage, the total amount of interest paid can be calculated by subtracting the balloon payment from the loan amount and dividing it by the number of payments over the life of the loan:
($1,750,000 - $1,423,723) * 2.5% / (12 * 6) = $63,011.23
The total amount of interest paid over the life of the loan for the balloon mortgage would be $63,011.23.
Therefore, the savings for the property investor would be $63,750 - $63,011.23 = $738.77, which is the answer to option B, $340,329.83.

Red light is particularly effective for photosynthesis because it has a longer wavelength and lower energy, which allows chlorophyll to efficiently absorb it and use it for the photosynthetic process.
In photosynthesis, plants use light energy to synthesize glucose from carbon dioxide and water.
As a result, photosynthesis is maximum in red light because plants can absorb and utilize this light energy most efficiently for their growth and energy production.

We can conclude that the correct answer is OA. A(1, -3), B(4, -3), C'(4, -4), D'(1,-4).
What are the factors?
what are factorsIn mathematics, a factor is a number that divides another number without leaving a remainder. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12, because these numbers divide 12 without leaving a remainder.
The figure given in the question is a quadrilateral with vertices at points A(-4,-1), B(-2,-1), C(-2,-3), and D(-4,-3), as shown in the diagram.
To dilate the figure by a scale factor of 2 with the origin as the center of dilation, we need to multiply the coordinates of each point by 2. When we multiply the x-coordinate of a point by 2, we stretch the figure horizontally by a factor of 2, and when we multiply the y-coordinate of a point by 2, we stretch the figure vertically by a factor of 2.
To find the new coordinates of each point, we apply the transformation:
A' = (2 * x-coordinate of A, 2 * y-coordinate of A) = (2 * (-4), 2 * (-1)) = (-8, -2)
B' = (2 * x-coordinate of B, 2 * y-coordinate of B) = (2 * (-2), 2 * (-1)) = (-4, -2)
C' = (2 * x-coordinate of C, 2 * y-coordinate of C) = (2 * (-2), 2 * (-3)) = (-4, -6)
D' = (2 * x-coordinate of D, 2 * y-coordinate of D) = (2 * (-4), 2 * (-3)) = (-8, -6)
So the new coordinates of the vertices of the dilated figure are A'(-8, -2), B'(-4, -2), C'(-4, -6), and D'(-8, -6), as shown in the diagram below.
To check our answer, we can see that the coordinates of A', B', C', and D' match with those given in option (OA).
Threfore, we can conclude that the correct answer is OA. A(1, -3), B(4, -3), C'(4, -4), D'(1,-4).

Jeriel is going to invest in an account paying an interest rate of 6.5% compounded continuously. How much would Jeriel need to invest, to the nearest cent, for the value of the account to reach $137,000 in 5 years?
Jeriel would need to invest approximately $98,986.25 for the value of the account to reach $137,000 in 5 years, assuming continuous compounding.
How much would Jeriel need to invest for the account to reach the accrued amount?The formula accrued amount compounded continuously is expressed as;
A = P × e^(rt)
Where A is accrued amount, P is principal, r is interest rate and t is time.
In this case, we are given that the final amount to be $137,000, the interest rate is 6.5% and the time is 5 years.
We want to solve for Principal P.
First, convert R as a percent to r as a decimal
r = R/100
r = 6.5/100
r = 0.065 per year
Plug these values into the above formula and solve for P.
A = P × e^(rt)
P = A / e^(rt)
P = 137,000.00 / e^(0.065 × 5)
p = $98,986.25
Therefore, the value of the principal P is $98,986.25.

How do I solve for x and y?
Answer:
x = 80
y = 160
Step-by-step explanation:
The sum of all arc measures that make up a circle is 360°. Therefore:
[tex]\implies 200^{\circ} + y^{\circ} = 360^{\circ}[/tex]
[tex]\implies 200^{\circ} + y^{\circ} - 200^{\circ} = 360^{\circ} - 200^{\circ}[/tex]
[tex]\implies y^{\circ} = 160^{\circ}[/tex]
[tex]\implies y=160[/tex]
Tangent and Intersected Chord TheoremIf a tangent and a chord intersect at a point on a circle, then the measure of each angle formed is one-half the measure of its intercepted arc.
Therefore, according to the Tangent and Intersected Chord Theorem, the measure of angle x is equal to half of the measure of arc y:
[tex]\implies x^{\circ}=\dfrac{1}{2} y^{\circ}[/tex]
[tex]\implies x^{\circ}=\dfrac{1}{2} \cdot 160^{\circ}[/tex]
[tex]\implies x^{\circ}=80^{\circ}[/tex]
[tex]\implies x=80[/tex]
