From the given scatter plot,  point L is an outlier. The association is negative linear association.  The line is not the best fit accurate. Graph shows a negative linear association. As the number of weeks increases, the number of tickets sold decreases

What is scatter plot?

A scatter plot is a type of data visualization that displays the relationship between two numerical variables. It is a graph with points plotted on it that represent the values of two different variables.

1. In a scatter plot, an outlier is a data point that lies far away from the other data points in the plot, and is not in line with the overall pattern or trend that the other data points display.

2. The scatter plot for this data is likely to show a negative linear association between the number of people in a group and the zoo ticket price per person. As the number of people in a group increases, the zoo ticket price per person decreases.

The rate of change of Zoo Ticket Price with respect to the the number of persons:

[tex]m=14.50-1500/2-1=-0.5[/tex]

3. No because the line should touch every point.  When we draw a line passing through the origin, it passes through the data points (2,3), (4,3), and (4,5), but it does not pass through the other data points (6,5), (6,6), and (8,7).

This indicates that the line of best fit may not accurately represent the overall trend of the data.

4. The given data points are (1,5), (2,4), (3,3), (4,2), (5,1), and (6,0). When we plot these points on a graph with x-axis representing variable x and y-axis representing variable y, we get a downward sloping straight line passing through all the points.

This pattern suggests a negative linear association between the variables x and y. As the value of x increases, the value of y decreases at a constant rate.

Therefore, the graph shows a negative linear association between x and y.

5. The answer is option (a) "As the number of weeks increases, the number of tickets sold decreases".

As per the given data points and the line passing through (1,100) and (6,35), we can observe that the number of tickets sold decreases as the number of weeks a movie has been in theaters increases. Therefore, the statement "As the number of weeks increases, the number of tickets sold decreases" best describes the relationship between the number of weeks a movie has been in theaters and the number of tickets sold.

Roberto bought a $340,000 house, paying 20% down, and financing the rest at 5% interest for 30 years. Her
monthly payments are $1460.15. How much will he really pay for her $340,000 house?
Roberto will pay a total of $
for the house.

Answers

Answer:

Therefore, Roberto will pay a total of $593,654 for his $340,000 house, including $253,654 in interest over the 30-year period.

Step-by-step explanation:

Roberto paid 20% down on a $340,000 house, which is 0.20 x $340,000 = $68,000.

So, the amount he financed is $340,000 - $68,000 = $272,000.

Roberto financed the $272,000 at 5% interest for 30 years, making monthly payments of $1460.15.

To find the total amount he will pay for the house, we need to calculate the total amount he will pay over the 30-year period.

First, we can calculate the total number of payments he will make over the 30 years by multiplying the number of years by the number of payments per year:

30 years x 12 months/year = 360 payments

The total amount Roberto will pay is the sum of all the monthly payments he makes over the 30 years:

Total amount = 360 x $1460.15 = $525,654

However, this includes both the principal amount of $272,000 and the interest he will pay over the 30 years. To find out how much he will pay in interest, we can subtract the principal from the total amount:

Total interest = $525,654 - $272,000 = $253,654

Therefore, Roberto will pay a total of $593,654 for his $340,000 house, including $253,654 in interest over the 30-year period.

if you borrow $2,500 when you open up account the loan was for 2 years and the amount of the loan interest was $155 what were you charge when you open up the account for the loan​

Answers

Answer:

the charge for opening up the account was $155.

Step-by-step explanation:

To find the charge for opening up the account, we need to subtract the interest from the total amount borrowed.

The total amount repaid at the end of the loan period is the sum of the amount borrowed and the interest charged. In this case, the total amount repaid is:

$2,500 + $155 = $2,655

The interest charged on the loan is the difference between the total amount repaid and the amount borrowed. Therefore, the amount charged for opening up the account is:

$2,655 - $2,500 = $155

So the charge for opening up the account was $155.

The value of XS in the perpendicular lines is 16 units.

How to find length of line segment?

The line VU is perpendicular to the line  XS. Perpendicular lines are defined as two lines that meet or intersect each other at right angles.

Therefore, perpendicular bisector is a line that divides a given line segment exactly into two halves forming 90 degrees angle at the intersection point.

Hence,

b + 5 = 3b - 1

b - 3b = -1 - 5

-2b = -6

divide both sides by -2

b = -6 / -2

b = 3

Therefore, let's find XS as follows:

XS = b + 5 + 3b - 1

XS = 4b + 4

XS = 4(3) + 4

XS = 12 + 4

Draw a dialation with center at the Irgun of the triangle with the vertices (2,0) ,(4-4), (6,2) scale factor of k =1.5

Answers

The sides of the dilated triangle are parallel to the sides of the original triangle, but their lengths are multiplied by the scale factor k.

What is triangle?

A triangle is a closed two-dimensional figure with three straight sides and three angles. It is one of the basic shapes in geometry and is used in many different areas of mathematics, science, and everyday life. A triangle is defined by its three vertices (or corners), which are the points where the sides of the triangle intersect. The three sides of the triangle are the line segments connecting the vertices. The three angles of the triangle are the angles formed by the intersection of two sides.

Here,

To dilate a triangle with a center at the origin, we need to multiply the coordinates of each vertex by the scale factor k. However, in this case, the center of dilation is not at the origin, but at the point Irgun. To perform the dilation, we can follow these steps:

Plot the original triangle with vertices (2,0), (4,-4), and (6,2).

Draw a line segment from the center of dilation Irgun to each vertex of the triangle.

Measure the distance from Irgun to each vertex, and multiply it by the scale factor k = 1.5 to find the new distance.

Use the new distances to construct the dilated triangle by drawing line segments from Irgun to points that are 1.5 times farther away from Irgun than the corresponding vertices of the original triangle.

The resulting dilation of the triangle with center at Irgun and scale factor k = 1.5 is shown below:

In this image, the original triangle is shown in black, and the dilated triangle is shown in blue. The center of dilation Irgun is marked with a red dot. Note that the new vertices of the dilated triangle are (0.5,0), (3,-6), and (7.5,3), which are 1.5 times farther away from Irgun than the corresponding vertices of the original triangle.

Since opposite angles are equal, this means that GHJK is a parallelogram, because opposite sides are parallel.

Describe Parallelogram?

Additionally, each pair of opposite sides of a parallelogram are congruent (of equal length), and the opposite angles of a parallelogram are also congruent (of equal measure). These properties make parallelograms useful in various fields such as engineering, architecture, and geometry.

There are different types of parallelograms, including rectangles, rhombuses, and squares, which have additional properties such as perpendicular sides, equal sides, or right angles. A rectangle is a type of parallelogram with four right angles, while a rhombus has four sides of equal length, and a square has both equal sides and right angles.

To prove that GHJK is a parallelogram, we need to show that opposite sides are parallel.

Since GK is parallel to HJ, we have:

∠LGK + ∠KHL = 180° (because GK // HJ)

But we are given that:

∠LGK = ∠LKL (given)

Therefore:

∠LKL + ∠KHL = 180°

This means that ∠KHL is a supplementary angle to ∠LKL.

Similarly, we can show that ∠KJH is a supplementary angle to ∠JKL:

∠JKL + ∠KJL = 180° (because GK // HJ)

But we are given that:

∠LGK = ∠LKL

Therefore:

∠LGK + ∠KJL = 180°

This means that ∠KJL is a supplementary angle to ∠LGK.

Now, we can use the fact that the opposite angles of a parallelogram are equal to show that GHJK is a parallelogram:

∠LKL = ∠JKL (alternate interior angles)

∠KHL = ∠KJH (alternate interior angles)

Since opposite angles are equal, this means that GHJK is a parallelogram, because opposite sides are parallel.

By keeping the equations balanced on both sides, we compute the values of the unknown variables. Finding the value of the variable that makes the condition of all the provided equations true is the primary goal when solving an equation system. A given system of equations may have a variety of solutions.

Let us suppose the width of the rectangle = w.

Given that, length is 5 more than four times its width.

Thus,

l = 5 + 4w

Now, the perimeter of the rectangle is given as:

P = 2(l + w)

Substitute the value of P = 180:

180 = 2l + 2w

The system of equations is:

l = 5 + 4w

180 = 2l + 2w

Substitute the value of l from equation 1 into equation 2:

180 = 2(5 + 4w) + 2w

180 = 10 + 8w + 2w

180 - 10 = 10w

170 = 10w

w = 17

Substitute the value of w = 17 in the first equation:

l = 5 + 4w

l = 5 + 4(17)

l = 73

Complete question -

What are the two numbers if their sum is −7 and their difference is 14?

A loan of $12,000 with interest at 14% compounded annually is to be amortized by equal payments at the end of each year for six years. What will the balance outstanding be after second year?

Answers

To calculate the balance outstanding after the second year of equal payments, we can use the formula for the future value of an annuity:

FV = PMT x [(1 + r)^n - 1] / r

Where:
FV = future value of the annuity
PMT = the equal payment amount
r = the interest rate per period (in this case, the annual interest rate divided by the number of payment periods per year)
n = the total number of payment periods

In this case, we have:
PMT = the equal payment amount
r = 14% / 1 = 14% per year (since interest is compounded annually)
n = 6 years
We need to first calculate the PMT using the formula for the present value of an annuity:

PMT = PV x [r / (1 - (1 + r)^(-n))]

Where:
PV = present value of the annuity

To find PV, we can use the formula for the present value of a lump sum:

PV = FV / (1 + r)^n

Where:
FV = the total loan amount
r = 14% per year
n = 6 years

Plugging in the values, we get:

PV = $12,000 / (1 + 0.14)^6
PV = $5,070.33

Now we can calculate PMT using the present value:

PMT = $5,070.33 x [0.14 / (1 - (1 + 0.14)^(-6))]
PMT = $2,360.63

Therefore, the equal payment amount is $2,360.63 per year.

To calculate the balance outstanding after the second year of payments, we can use the formula for the future value of an annuity with two years of payments:

FV = PMT x [(1 + r)^n - 1] / r

Where:
FV = the future value of the annuity after two years of payments
PMT = $2,360.63
r = 14% / 1 = 14% per year (since interest is compounded annually)
n = 2 years

Plugging in the values, we get:

FV = $2,360.63 x [(1 + 0.14)^2 - 1] / 0.14
FV = $4,950.53

Therefore, the balance outstanding after the second year of payments is $4,950.53.

List the first 5 elements of set A

Answers

The first 5 elements of set A are: {-1, -2, 1, -3, 2}.

What is the set of elements?

The objects in a set are called the elements (or members ) of the set; the elements are said to belong to the set (or to be in the set), and the set is said to contain the elements. Usually, the elements of a set are other mathematical objects, such as numbers, variables, or geometric points.

Set A is defined as:

A = {x | x = k(-1)ⁿ where k ∈ Z* and n ∈ N}

To find the first 5 elements of A, we can substitute different values of k and n:

For k = 1 and n = 1, x = 1(-1)¹ = -1

For k = 2 and n = 1, x = 2(-1)¹ = -2

For k = 1 and n = 2, x = 1(-1)² = 1

For k = 3 and n = 1, x = 3(-1)¹ = -3

For k = 2 and n = 2, x = 2(-1)² = 2

Therefore, the first 5 elements of set A are: {-1, -2, 1, -3, 2}.

The vector components and direction of the river and motorboat are;

(a) 12·i

(b) 12·i + 12·√3·j

(c) 24·i + 12·√3·j

(d) 31.7 mi/h

The direction of the motorboat is N 49.1° E

What is a vector?

A vector is a quantity or measurement that indicates a magnitude and a direction of the measurement.

The direction the river flows = East

The speed of the river = 12 mi/h

The direction the boater heads = 60° from the shore

Speed of the motor boar = 24 mi/h

The unit vector in the east direction = i

Unit vector in the north direction = j

(a) The velocity of the river, which is 12 mi/h east expressed in vector form is therefore;

12·i

(b) The velocity of the motorboat relative to the river, in vector component form is therefore;

Component of the velocity in the east direction = 24 × cos(60°)·i = 12·i

Component in the north direction = 24 × sin(60°)·j = 12·√3·j

The component form of the velocity of the boat is therefore;

[tex]\vec{v}[/tex] = 12·i + 12·√3·j

(c) The true velocity of the boat is the vector sum of the velocity of the river and the velocity of the boat, therefore;

True velocity of the boat = 12·i + 12·i + 12·√3·j = 24·i + 12·√3·j

True velocity of the boat = 24·i + 12·√3·j

(d) The true speed is the magnitude of the velocity of the boat which can be found ads follows;

[tex]| \vec{v}|[/tex] = √(24² + (12·√3)²) ≈ 31.7

The (true) direction of the motorboat, θ, can be obtained from the arctangent of the ratio of the velocity component in the northern direction to the velocity in the eastern direction as follows;

The velocity component of the motorboat in the northern direction = 12·√3

The component of the velocity in the eastern direction = 24

Therefore;

tan(θ) = 12·√3/(24)

θ = arctan(12*√3/(24)) ≈ 40.9°, which is about East 40.9° North

The direction from the north, therefore is found as follows;

Direction = N (90° - 40.9°) E ≈ N 49.1° E
