Laurie sold a house and made a commission of $14,050. She charges her customers a commission fee of 2. 5% on the selling price of the house. How much was the selling price of the house Laurie sold?

Answers

The selling price of the house that Laurie sold was $562,000.

The selling price is the amount paid by the customer to purchase the goods. The actual selling price is the amount paid by the customer for a product or service. This is the price that is more than the cost of products and includes a proportion of profit.

The cost price of an item is the amount spent to buy it or the price at which it is manufactured.

Let's call the selling price of the house "P".

The commission fee of 2.5% on the selling price of the house is equal to 0.025 * P.

Since Laurie made a commission of $14,050, we can set up the following equation:

0.025 * P = 14050

Dividing both sides by 0.025:

P = 14050 / 0.025 = 562000

Answer:

$81.15

Step-by-step explanation:

So to find the total amount of money, you take the original price and add the sales tax.

We need to find the sales tax first, which is telling us to multiply the original price by 0.065.. so lets do that

(79.95)(0.065) = 5.19675

Since we got that answer there, we add that to the original price

$79.95 + $5.19675 = $81.14675

Which solutions fromn (c) arC exact? Which solutions are unique?

Answers

The "best" solution z+ = A^+b is the one that minimizes the 2-norm of the residual vector r = b - Az. In general, not all right-hand sides b will have a unique solution z+, and even if there is a solution, it may not be exact (i.e., Az ≠ b).

To find the pseudoinverse of a matrix A, the first step is to take the singular value decomposition (SVD) of A, which can be written as A = UΣV^T, where U and V are orthogonal matrices and Σ is a diagonal matrix with nonnegative singular values. The pseudoinverse of A is given by A^+ = VΣ^+U^T, where Σ^+ is the same as Σ except that the nonzero elements of Σ are replaced by their inverses.

Next, the projection matrices are given by AtA and AA+, which are used to project a vector onto the column space and the row space of A, respectively.

The "best" solution z+ = A^+b is the one that minimizes the 2-norm of the residual vector r = b - Az. In general, not all right-hand sides b will have a unique solution z+, and even if there is a solution, it may not be exact (i.e., Az ≠ b).

Whether a solution is exact or unique depends on the rank of A and the number of linearly independent columns and rows. If the rank of A is equal to the number of columns, then the solution is unique, otherwise, the solution may not be unique.

Therefore, The "best" solution z+ = A^+b is the one that minimizes the 2-norm of the residual vector r = b - Az. In general, not all right-hand sides b will have a unique solution z+, and even if there is a solution, it may not be exact (i.e., Az ≠ b).

Equation 1: 10·x - 2·y = 15

Equation 2: 4·x + y = 6

Plugging in the values of x = 1.5, y = 0, we get;

10 × 1.5 - 2 × 0 = 15

4 × 1.5 + 0 = 6

The point (1.5, 0), satisfies both equations in the system of equations, therefore, the point (1.5, 0) is a solution of the system of equations.

Answers

If Jackson invested $320 in an account paying an interest rate of 3. 2% compounded continuously, assuming no deposits or withdrawals are made, it would take: 3.37 years

for the value of the account to reach $410

To solve this problem, we can use the formula for continuously compounded interest:

A = P * e^(rt)

where A is the final amount, P is the initial amount (320), r is the interest rate (3.2%), and t is the time in years.

Solving for t, we get:

t = (ln(A/P)) / (r)

Plugging in the values, we get:

t = (ln(410/320)) / (0.032)

Approximating this, we get:

t = 3.37 years, rounded to the nearest tenth of a year.

So it would take about 3.4 years for the value of the account to reach $410.

42 students are picking two activities to do over the weekend.5 picked painting and sport.
8 did not pick painting or sport.
Twice as many students picked sport than painting as one of their activities.Find the amount that picked sport and not painting.

Answers

Answer:

25/3

Step-by-step explanation:

Let's call the number of students who picked sport "s" and the number of students who picked painting "p". We know:

p + s = 5 (the number of students who picked painting and sport)

42 - p - s = 8 (the number of students who did not pick either)

s = 2p (twice as many picked sport as painting)

From the first equation, we can solve for p:

[tex]\sf:\implies{p + 2p = 5}[/tex]

[tex]\sf:\implies{3p = 5}[/tex]

[tex]\sf:\implies{p = 5/3}[/tex]

So, 5 students picked painting and 10 students picked sport. And the number of students who picked sport but not painting is:

s - p = 10 - 5/3 = 10 - 5/3 = 25/3.

Your foot measure in centimeter is 4.25 centimeters and the proportion is 10.8 inches / 2.54 centimeters = x centimeters.

A proportion is an equation that states that two ratios are equal. It's often used to convert from one unit of measurement to another.

In your case, you want to convert 10.8 inches to centimeters, so you'll use a proportion to help you do that.

Here the correct proportion to use is 10.8 inches / 2.54 centimeters = x centimeters.

In this proportion, the first ratio on the left side of the equation represents 10.8 inches in terms of centimeters, and the second ratio on the right side of the equation represents x centimeters in terms of inches.

Since we know the conversion factor between inches and centimeters, 2.54 centimeters per inch, we can substitute that into the proportion.

=> 10.8 inches / 2.54 centimeters = x centimeters

=> 10.8 inches / 2.54 centimeters

Find a power series representation for the function.

Determine the radius of convergence, R.
R =

Answers

As a result, the radius of convergence, R, is equal to one. As a result, f(x) = x(1 + 8x)^2 = x(1 + 16x + 64x^2 +...) = x + 16x^2 + 64x^3 +... This is the function f's power series representation (x).

What is function?

A function is an equation with just one solution for y for every x. A function produces exactly one output for each input of a certain type. Instead of y, it is usual to call a function f(x) or g(x). f(2) indicates that we should discover our function's value when x equals 2. Example.

Here,

The power series representation for f(x) = x(1 + 8x)^2 can be found by expanding the function (1 + 8x)^2 as a Taylor series centered at x = 0:

(1 + 8x)^2 = 1 + 16x + 64x^2 + ...

So, f(x) = x(1 + 8x)^2 = x(1 + 16x + 64x^2 + ...) = x + 16x^2 + 64x^3 + ...

This is the power series representation for the function f(x).

To determine the radius of convergence, R, we use the formula:

R = 1 / limsup |a_n|^(1/n)

where a_n is the nth coefficient in the power series and limsup refers to the limit superior of the sequence {|a_n|^(1/n)}.

In this case, a_n = 16n x^n, so |a_n|^(1/n) = |16n|^(1/n) * |x|^(1/n). Since |16n|^(1/n) is a constant, the limit superior is just equal to |x|^(1/n). Therefore,

R = 1 / limsup |a_n|^(1/n) = 1 / |x|^(1/n) = 1

So, the radius of convergence, R, is equal to 1. So, f(x) = x(1 + 8x)^2 = x(1 + 16x + 64x^2 + ...) = x + 16x^2 + 64x^3 + ... This is the power series representation for the function f(x).

some of our farm fields are being left unused. does this have any implications for the economy's ppf diagram (with agricultural products on one axis and all other products on the other axis)?

Answers

Yes, the implications of leaving farm fields unused for the economy's PPF diagram can be seen in the output of agricultural products.

The PPF diagram shows the maximum output of two products that an economy can produce at a given time, and it is shaped like a curve. When farm fields are left unused, the amount of agricultural products that can be produced is decreased, resulting in a shift in the PPF curve inwards. This means that the economy has to sacrifice other goods to maintain the same level of production of agricultural products, leading to an opportunity cost. Thus, leaving farm fields unused has implications for the economy's PPF diagram, as it reduces the output of agricultural products, resulting in a shift in the PPF curve inwards.

Mr chua bought a vanguard sheet with dimension 75 cm by 90 cm . He cut squares of identical size from the vanguard sheet such that there was no wastage


(a) What was the largest possible length of the side of each square he cut out?

(b) What was the total number of squares he cut out?

Answers

Answer:
(A) - The largest possible length of the side of each square is 15 cm.

(B) - The total number of squares he cut out is 6750 / 225 = 30 squares.

Explanation:

(a) To find the largest possible side length of each square, we need to determine the greatest common factor of the length and width of the vanguard sheet.

The greatest common factor of 75 and 90 is 15, so the largest possible length of the side of each square is 15 cm.

(b) To find the total number of squares he cut out, we need to divide the area of the vanguard sheet by the area of each square.

The area of the vanguard sheet is 75 cm * 90 cm = 6750 square cm.

The area of each square is 15 cm * 15 cm = 225 square cm.

So the total number of squares he cut out is 6750 / 225 = 30 squares.

(a) To find the largest possible length of the side of each square he cut out, we need to find the greatest common divisor (GCD) of the lengths of the two sides of the Vanguard sheet. The GCD can be found using the Euclidean algorithm, which states that the GCD of two numbers is the same as the GCD of the smaller number and the remainder of the division of the larger number by the smaller number.

75 cm and 90 cm have a GCD of 15 cm, so the largest possible side length of each square is 15 cm.

(b) To find the total number of squares he cut out, we divide the area of the Vanguard sheet by the area of each square:

Area of Vanguard sheet = 75 cm * 90 cm = 6750 square cm
Area of each square = 15 cm * 15 cm = 225 square cm

Total number of squares = 6750 / 225 = 30

So, Mr. Chua cut out 30 squares of side length 15 cm from the Vanguard sheet

Monthly maintenance costs are distributednormally with a μ=$250 and σ=$50. What percent of months have maintenancecosts in the range of $200 to $300?

Answers

68.26% percent of months have maintenance costs in the range of $200 to $300

How do you calculate maintenance costs?

The monthly maintenance cost per square foot is calculated by dividing the total cost by the property's total area. It is multiplied by the unit area of each home to determine the individual maintenance contributions.

Your home's square footage can also be used to estimate your yearly maintenance expenses. If you follow this guideline, you should begin by figuring annual maintenance expenditures at $1 per square foot. Your estimated annual maintenance cost for a 2,000 square foot home is $2,000.

Costs incurred during normal measures to maintain an asset's original state are referred to as maintenance costs. Simple electrical repairs, bulb replacement, paint touch-ups, pool cleaning, etc. are a few examples of maintenance charges.

Remember that, [tex]P(X < A) = P(Z < (A - \mu )/\sigma)[/tex]

and given that \mu = [tex]$250\ and \ \sigma = \$50[/tex]

So, P(maintenance cost is in the range $200 to $300) = P(200 < X < 300)

= P(X < 300) - P(X < 200)

= P(Z < (300 - 250)/50) - P(Z < (200 - 250)/50)

= P(Z < 1) - P(Z < -1)

= 0.8413 - 0.1587

= 0.6826

= 68.26%

Thus, 68.26% percent of months have maintenance costs in the range of $200 to $300

3.) Katy Perry's bank granted her a single-payment loan of $4,400 at an interest rate of 6% exact interest to buy
a new sound system. The term of the loan is 172 days. What is the exact interest and what is the maturity value
of the loan?

Answers

The interest on the loan is: $375.44

The maturity value is: $4,775.44.

How to Calculate Maturity Value and Interest on a Loan?

Maturity value and interest on a loan can be calculated as follows:

Maturity value: it is the amount of the loan plus the interest charged on it. It can be calculated using the formula:

MV = P + I

where MV is the maturity value, P is the principal (original loan amount), and I is the interest charged on the loan.

Interest: it is the amount charged by the lender for the use of their money. It can be calculated using the formula:

I = P * r * t

where I is the interest, P is the principal, r is the interest rate, and t is the term of the loan (in years or days).

Therefore:

Exact interest: 4,400 * 6% * 172/365 = $375.44

Maturity value: 4,400 + 375.44 = $4,775.44

How can you add and subtract positive and negative numbers in complicated expressions?

Answers

When dealing with complicated expressions that involve the addition and subtraction of positive and negative numbers, it is important to remember the following rules.

What is numbers?

Nobody's a mathematical object used to count level and measure it is in the fundamental concept in mathematics and you used in many different way number can be used to represent anything from quantity of object to ideas in the concept additionally number are used to describe relationship between different object or concept.

First, when adding or subtracting two numbers with the same sign, the sum or difference will have the same sign as the numbers. For example, adding 5 + 3 gives 8 and subtracting 5 – 3 gives 2, both of which are positive numbers.

Second, when adding or subtracting two numbers with different signs, the sum or difference will have the sign of the number with the largest absolute value. For example, adding 5 + (-3) gives 2 and subtracting 5 – (-3) gives 8, both of which are positive numbers.

Third, when multiplying and dividing positive and negative numbers, the product or quotient will have the sign of the number with the largest absolute value. For example, multiplying 5 x (-3) gives -15 and dividing 5 / (-3) gives -1.67, both of which are negative numbers.

Finally, when dealing with expressions with multiple operations, it is important to use the correct order of operations: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). This allows for the correct evaluation of an expression.

By remembering these rules, it is possible to add and subtract positive and negative numbers in complicated expressions.

what is a quadrilateral symmertrical across both diagonals

Answers

A rhombus has reflectional symmetry over either of its diagonals.

Define quadrilateral?In geometry, a quadrilateral is a four-sided polygon with four edges and four corners. The word is derived from the Latin words quadri (a variant of four) and latus (a side).Quadrilaterals are shapes with four sides and four corners, or vertices, and two of the sides are often parallel, which means they are always the same distance apart no matter how long they stretch. Squares and rectangles are the most common quadrilaterals, but there are also trapezoids, parallelograms, and kites.A quadrilateral is a closed shape and type of polygon with four sides, four vertices, and four angles. It is formed by connecting four non-collinear points.The sum of the interior angles of quadrilaterals is always 360 degrees.

Determine the intervals on which the following function is continuous. f(x) = x + 6/x^2 - 36 The function is continuous on the interval(s) (Simplify your answer. Type your answer in interval notation. Use a comma to separate answers as needed.)

Answers

Function is continuous everywhere expect x = 6 and  x = -6

What does a math interval mean?

In mathematics, an interval is quantified in terms of numbers. The range of numbers between any two specific numbers is known as the interval.

                         Every real number between those two values is included in this range. All kinds of numbers, including imaginary ones, are real numbers.

The function will not be continuous if the denominator becomes zero .

   f(x)  =  x+6/(x² - 36 )

to become denominator zero -

      x² - 36  = 0

    (x + 6) ( x - 6 ) =0

    x = 6  or   x = -6

so at x = 6 and x = -6 the function is not continuous .

  the interval for continuity is -

      = ( -∞ , - 6), ( -6 , 6) , ( 6, ∞ )

  In other words function is continuous everywhere expect x = 6 and

x = -6
