Answer: We can start by using the formula for calculating commission:

Commission = Rate x Sales

where Rate is the commission rate and Sales is the amount of sales.

In this case, we know the commission earned ($4008) and the commission rate (6%), but we don't know the amount of sales. We can set up an equation and solve for Sales:

$4008 = 0.06 x Sales

Dividing both sides by 0.06, we get:

Sales = $4008 ÷ 0.06 = $66,800

Therefore, the salesperson sold $66,800 worth of video equipment.

Step-by-step explanation:

Her answer shows the ratio of 6:24- lemonade to punch.

The monthly payment for a 30-year mortgage in this scenario is $1,713.78.

What are Percentages?

Percentages are a way of expressing a proportion or ratio in terms of a fraction of 100.

To solve this problem, we can use the formula for calculating the monthly payment for a mortgage:

[tex]M = P[r(1+r)^n/((1+r)^n)-1][/tex]

where M is the monthly payment, P is the principal (the amount borrowed), r is the monthly interest rate, and n is the number of monthly payments (the term of the loan in months).

First, we need to calculate the down payment, which is 10% of the purchase price:

Down payment = 0.1 x $340,000 = $34,000

The principal is the purchase price minus the down payment:

Principal = $340,000 - $34,000 = $306,000

Next, we need to calculate the monthly interest rate. The annual interest rate is 5.3%, so the monthly interest rate is:

r = 0.053/12 = 0.00441667

Finally, we need to calculate the number of monthly payments. A 30-year mortgage has 360 monthly payments (30 years x 12 months per year).

n = 360

Now we can plug in these values into the formula and solve for M:

[tex]M = \$306,000[0.00441667(1+0.00441667)^360/((1+0.00441667)^360)-1][/tex]

M = $1,713.78

Therefore, the monthly payment for a 30-year mortgage in this scenario is $1,713.78.

The mean of the sampling distribution is 606060 and the standard deviation is 871.78.

As long as the sample size is sufficient (usually, n 30), the central limit theorem implies that if we repeatedly take random samples from a population, the sampling distribution of the sample means will resemble a normal distribution, regardless of the form of the population distribution. This indicates that given the sample mean and standard deviation, we may utilise the normal distribution to draw conclusions about the population mean. Because it enables us to estimate population parameters even when we don't know the population distribution, the central limit theorem is significant.

Given that,

n = 757575

p = 80% = 0.8

q = 1 - 0.8 = 0.2

The mean of the binomial distribution is given as:

Mean: μ = np = (757575)(0.8) = 606060

The standard deviation of the binomial distribution is given as:

σ = √(npq) = √((757575)(0.8)(0.2)) = 871.78

Hence, the mean of the sampling distribution is 606060 and the standard deviation is 871.78.

Step-by-step explanation:

Area = w X l     =   1/2  yd  X  7/6  yd   =   (1*7) / (2*6) =   7/12 yd^2

Answer:

7/12 sq yd

Step-by-step explanation:

The area of a rectangle (which includes a rug) is given by the formula:

Area = Length x Width

We are given that the rug is 1/2 yard wide and 7/6 yards long. So, we can substitute these values into the formula:

Area = (7/6) x (1/2)

To multiply these fractions, we need to find a common denominator. The least common multiple of 6 and 2 is 6, so we can convert both fractions to have a denominator of 6:

Area = (7/6) x (1/2) = (7/6) x (3/3) x (1/2) = 21/36

We can simplify this fraction by dividing the numerator and denominator by their greatest common factor, which is 3:

Area = 21/36 = (21 ÷ 3) / (36 ÷ 3) = 7/12

Therefore, the area of the rug is 7/12 square yards.

keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

[tex]y=\stackrel{\stackrel{m}{\downarrow }}{4}x-1\qquad \impliedby \qquad \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

so we're really looking fo the equation of a line whose slope is 4 and it passes through (-3 , 2)

Using compound interest, each payment should be $948.86, rounded to two decimal places.

The interest on savings that is computed on both the initial principal and the interest accrued over time is known as compound interest. Compound interest is computed by multiplying the starting principal amount by one and the annual interest rate raised to the number of compound periods minus one. The final step is to deduct the initial loan principal from the calculated value.

When the amount compounds quarterly, it means that the amount compounds 4 times in a year. i.e., n = 4. We use this fact to derive the quarterly compound interest formula. Thus, the quarterly compound interest formula is:

[tex]A = P (1 + r/4)^t[/tex]

To determine the size of each payment that needs to be made at the end of every 2 months, we can use the formula for the future value of an annuity:

[tex]FV = Pmt x [(1 + r)^{n - 1}] / r[/tex]

When we enter these values into the formula, we obtain:

In this instance, we know that the sinking fund's future value should be $61,000, the interest rate each 2-month period is 5.9%/6 = 0.983%, and there are a total of 54 periods (9 years x 12 months/year / 2 months/period = 54 periods) in the sinking fund's life.

[tex]$61,000 = Pmt x [(1 + 0.00983)^{54 - 1}] / 0.00983[/tex]

Solving for Pmt, we get:

[tex]Pmt = $61,000 x 0.00983 / [(1 + 0.00983)^{54 - 1}][/tex]

= $61,000 x 0.00983 / 0.6346

The surface area of the larger prism is 24b + (5/2)(bc + bd + cd) + 5/2.

Surface area is the sum of the areas of all the faces (or surfaces) of a three-dimensional object. It is a measure of how much area the surfaces of an object take up in two dimensions. The surface area of a solid can be found by adding up the areas of its faces.

Let's call the other dimensions of the blocks "a", "b", "c", and "d", with "a" and "c" being the lengths, and "b" and "d" being the widths. Then, we have:

Block 1: a x b x c = 15

Block 2: a x b x d = 15

When we join the blocks together, we get a larger rectangular prism with dimensions 12 x b x (c + d). The surface area of this prism can be found by adding up the areas of its six faces:

Surface area = 2(12b) + 2(bc + bd + cd)

Surface area = 24b + 2(15 + bc + bd + cd)/12

Surface area = 24b + (5/2)(bc + bd + cd) + 5/2

Therefore, the surface area of the larger rectangular prism is given by:

Surface area = 24b + (5/2)(bc + bd + cd) + 5/2

Answer:

Step-by-step explanation:

a. Variables:

D0 = Demand for nurses in 2000 = 2,000,000

S0 = Supply of nurses in 2000 = 1,890,000

D2020 = Projected demand for nurses in 2020 = 2,810,414

S2020 = Projected supply of nurses in 2020 = 2,001,998

Equations:

For 2000: D0 = S0

For 2020: D2020 = S2020

b. Using substitution, we can set the two equations equal to each other:

D0 = S0

2,000,000 = 1,890,000 + m(S0 - 1,890,000) (where m is the rate of increase in supply)

m = 0.063

Now we can use this value of m to find out during which year the supply of nurses was equal to the demand:

2,000,000 = 1,890,000 + 0.063(S - 1,890,000)

S = 2,013,008

Therefore, the supply of nurses was equal to the demand in the year 2013.

Answer:

Julius: 52

John: 47

Grace: 51

Step-by-step explanation:

Let marks scored by Julius, John and Grace be x, y and z respectively

From the information given,
"Julius scored 5 more marks " →   x = y + 5  (1)

"who in turn scored 4 marks less than Grace" →  y = z - 4  (2)

Substitute y =  z - 4 in equation x = y + 5

→  x = (z-4) + 5

→ x = z - 4 + 5

→ x = z + 1

"The total mark scored by the three students was 150":
x + y + z = 150      (3)

Substitute x = z - 1 and y = z - 4 in equation (3):

←  (z + 1) + (z - 4) + z = 150
→  z -+ 1 + z - 4 + z = 150

→  z + z + z +  1 -  4 = 150
→  3z - 3 = 150

→  3z = 150 + 3 = 153

→ z = 153/3 = 51
So Grace's mark was 51

John's mark y = z - 4 = 51 - 4 = 47

Julius' mark x = y + 5 = 47 + 5 = 52

Substitute for y from (2) in (4):
2(z - 4) + z = 145

2z - 8 = 145

Mrs. Tempio can squirt 4 times as far as Zacarias can, therefore if Zacarias can only squirt 20 metres, Mrs. Tempio can squirt 4 * 20 = 80 metres.

Let's break down the issue to see why. We are aware of Zacarias' 20-meter squirt distance as well as Mrs. Tempio's 4-times-greater squirt distance. Thus, if we write up the following equation and assume that x is the that Mrs. Tempio may squirt:

x = 4 * 20

When we simplify this equation, we obtain:

x = 80

Mrs. Tempio can squirt 80 metres as a result.

Mathematicians research numbers, their variants, equations, associated structures, forms, and possible configurations of these. The word "function" describes the connection between a group of inputs, each of which has a corresponding output. A function is a connection between inputs and outputs where each input results in a single, distinct outcome. Each function has a domain, codomain, or scope assigned to it. Functions are usually denoted by the letter f. (x). An x is entered. On functions, one-to-one capabilities, so multiple capabilities, in capabilities, and on functions are the four main categories of accessible functions.

The sine function of the form f(x) = -2sin(x) is an amplitude-scaled sine function.

The sine function's amplitude is represented by the coefficient, which in this example is -2. Hence, the function's amplitude is 2.

The equation T = 2/, where is the angular frequency, yields the period of the function. The angular frequency of a sine function is given by = 2/T.

With the function f(x) = -2sin(x) substituted, we get:

ω = 2π/T

Sin(x + ) = -2sin(x)

To solve for T, we obtain:

T = 2π/ω = 2π/(-2) = -π

We use T's absolute value as the period cannot be negative, making the function's period T =.

As a result, the function's amplitude is 2 and its period is.

The correct answer is:

Major Axis Endpoints: (6, -3) and (-2, -3)

Minor Axis Endpoints: (2, 3) and (2, -9).

The major axis of a graph is the line that divides it in two equal parts. It is also known as the x-axis or the y-axis and it is the axis that is perpendicular to both the x and y axes. The major axis is an important part of the graph because it is used to plot the points on the graph. The points on the graph are plotted in relation to the major axis, allowing for easier interpretation of the graph.

The endpoints of the major axis of an ellipse are the points on the ellipse which are farthest away from each other. These points are located on the longest diameter of the ellipse and are the points at which the ellipse changes directions. Similarly, the endpoints of the minor axis of an ellipse are the points on the ellipse which are closest to each other.

In the equation (x−2)212+(y+3)236=1, the equation describes an ellipse which has its center located at the point (2, -3). The major axis of this ellipse has endpoints located at the points (6, -3) and (-2, -3). The minor axis of this ellipse has endpoints located at the points (2, 3) and (2, -9).
