A new business has total sales of $14,000, applied $1,350 in merchandise discounts, and had returns of $234. Calculate the business's total net sales.
a) $12,416
b) $13,219
c) $13,767
d) $16,000
Answers
The Business's total net sales would be $12,416
What is net sale?
Net sales are the total of a company's gross sales less any discounts, returns, and allowances. External transparency of net sales calculations is not always present. They are frequently accounted for when top line revenues are reported just on income statement. When examining a company's revenues, revenue growth, as well as operational expenses, the income statement is indeed the financial statement that is the most frequently used.
Discounts offered refer to discounts applied to the merchandise.
Net sales are calculated as total sales less any merchandise discounts and returns.
Net sales = total sales - ( discounts + returns)
Net sales = $14,000 - ( $1,350 + $234)
Net sales = $14,000 - $1,584
Net sales = $12,416
Hence, The Business's total net sales would be $12,416
Therefore, Option a) $12,416

The equation y = mx + b, when isolated for the variable m, gives us m in terms of x, y, and b, as m = (y - b)/x.
What is the isolation of a variable in an equation?
Equations are relations between two quantities involving variables raised to multiple powers, making up terms along with numerals.
Isolation is the process of moving one variable to one-side of the equation and everything else on the other side of the equation.
How to solve the question?
In the question, we are given an equation, y = mx + b, and are asked to write m in terms of x, y, and b.
This means that we need to isolate the variable m, to get an expression equal to m.
The isolation of the variable m can be done as follows:
y = mx + b,
or, y - mx = mx + b - mx {Subtracting mx from both sides},
or, y - mx = b {Simplifying},
or, y - mx - y = b - y {Subtracting y from both sides},
or, -mx = b - y {Simplifying},
or, (-mx)/(-x) = (b - y)/(-x) {Dividing both sides by (-x)}
or, m = (y - b)/x {Simplifying}.
Thus, the equation y = mx + b, when isolated for the variable m, gives us m in terms of x, y, and b, as m = (y - b)/x.

the population (in millions) of a city t years from now is given by the indicated function. (a) find the relative rate of change of the population 7 years from now. (round your answer to one decimal place.) 1.8 % per year (b) will the relative rate of change ever reach 2.3%? yes no solution or explanation (a) (b) p(t)
Answers
The relative rate of population change after seven years from now is a) 1.7 % (rounded off to 1 decimal place) b) Yes, the relative rate of population change will reach 2.3% in 19.21 years
The function for population t years from now is P(t)= 2+ 1.2e^(0.04t)
a) relative rate of change of population
= P'(t) / P(t)
= (0+1.2e^(0.04t) * 0.04 )/ ( 2+ 1.2e^(.04t) )
= 0.048 e ^(0.04t) / (2 + 1.2e^(0.04t) )
Relative rate of change of population 7 years from now
= 0.048 e ^(0.04 * 7) / (2+ 1.2e^(0.04*7))
=0.0177 = 0.177 * 100 = 1.7 % per year (rounded off to one decimal place
b) For the relative rate of change to reach 2.3 %
P'(t) / P(t) = 2.3 % = 0.023
⇒(0+1.2e^(0.04t) * 0.04 )/ ( 2+ 1.2e^(0.04t) ) = 0.023
⇒0.048e ^(0.04t) = 0.046 + 0.0267e^(0.04t)
⇒e ^(0.04t) = 0.958 + 0.556e ^(0.04t)
⇒e ^(0.04t) ( 1 - 0.556) = 0.958
⇒e ^(0.04t) ( 0.444) = 0.958
⇒e ^(0.04t) = 2.157
⇒0.04t = ln(2.157) (applying ln on both sides)
⇒t = 19.21 years
The relative rate of population change is 2.3% in 19.21 years

Work out the size of angle a, b and c.
Give reasons for your answers.
Answers
Answer:
A:50⁰
B:100⁰
C:30⁰
Step-by-step explanation:
Angle A:
as you can see in the photo, there is a concave angle of A that is 310⁰.
Considering that a full angle is 360⁰, we can calculate A by subtracting the concave of A to the full 360⁰
360⁰-310⁰=50⁰
b:
by knowing that a flat angle is 180⁰, and the opposite of B is 80⁰, we subtract 80⁰ from 180⁰
180⁰-80⁰=100⁰
knowing that the sum of convex angles of any triangle is 180⁰, we already know A and B, C is missing.
so if we subtract A and B from 180⁰ we find C
180⁰-50⁰-100⁰=30⁰
Canada and the European Union require that cars be equipped with "daytime running lights," headlights that automatically come on at a low level when the car is started. Many manufacturers are now equipping cars sold in the United States with running lights. Will running lights reduce accidents by making cars more visible? An experiment conducted in a driving simulator suggests that the answer may be "Yes." What concerns would you have about generalizing the results of such an experiment?
Answers
Probably not all driving scenarios can be accurately simulated by a driving simulator. Additionally, it's likely that simulator users have a different mindset than when they're actually behind the wheel.
Define the term experiment?The cited data:
By improving visibility during the day, daytime running lights can reduce accidents. Daytime running lights are used to help drivers gauge the size of the vehicle.Idea applied in experiment:
An institutional review committee must first approve any human experiments. All participants must give their informed consent prior to participating. Any details pertaining to study participants must remain confidential.A driving simulator is therefore unlikely to adequately replicate all driving scenarios, which is one of our concerns about extending the outcomes of such an investigation.
Thus, users of driving simulators are also probably in a different frame of mind than they are while driving is real life.

find the exact area of the surface obtained by rotating the curve about the x-axis. x = 3 5y2, 1 ≤ y ≤ 2
Answers
The exact area of the surface obtained by rotating the curve x=3+5y^2 about the x-axis is approximately 37.78 square units.
To find the exact area of the surface obtained by rotating the curve x=3+5y^2 about the x-axis, we will use the formula for finding the surface area of a solid of revolution.The formula for finding the surface area of a solid of revolution is given by:S=2π∫abf(x)√(1+(f'(x))^2)dx
where f(x) is the function representing the curve to be rotated, a and b are the limits of integration, f'(x) is the derivative of the function f(x).In our case, the curve x=3+5y^2 needs to be rotated about the x-axis. To do this, we need to express the function y as a function of x.
x=3+5y^2
y=±√(x-3)/5
We take the positive square root since we are only considering the curve in the range 1≤y≤2.
So, we have:
f(x)=√(x-3)/5
f'(x)=1/(10√(x-3))We can now substitute these values into the formula for surface area:
S=2π∫1^2(√(x-3)/5)√(1+(1/(10√(x-3)))^2)dxSimplifying this integral is a bit difficult, so we will use a computer algebra system or an online integral calculator to evaluate the integral.
After evaluating the integral, we get the exact surface area of the solid of revolution to be approximately 37.78 square units.Therefore, the exact area of the surface obtained by rotating the curve x=3+5y^2 about the x-axis is approximately 37.78 square units.

Answers
The total number of votes registered in all is 571289.
To find out how many votes were registered in all, we need to add the number of valid votes, invalid votes, and the number of people who did not cast their votes.
So, the total number of votes registered in all is:
The problem asks to find out how many votes were registered in all in an election given the number of valid votes, invalid votes, and the number of people who did not cast their votes.
We can start by adding the number of valid votes and invalid votes because those are the votes that were cast, regardless of whether they were valid or not.
This gives us:
498656 (valid votes) + 6768 (invalid votes)
= 505424 votes.
498656 (valid votes) + 6768 (invalid votes) + 83865 (people who did not vote)
= 571289 votes.
The total number of votes registered in all is 571289
However, we also need to add the number of people who did not cast their votes, which is given as 83865.
Therefore, the total number of votes registered in all is:
505424 (valid and invalid votes) + 83865 (people who did not vote)
= 571289 votes.

an economist is interested in studying the incomes of consumers in a particular region. the population standard deviation is known to be $1,000. a random sample of 50 individuals resulted in an average income of $15,000. what total sample size would the economist need to use for a 95% confidence interval if the width of the interval should not be more than $100? question 30answer a. n
Answers
The economist would need a total sample size of 3,792 individuals for a 95% confidence interval with an interval width of no more than $100.
To calculate the required sample size, we can use the formula:
n = [(Z * σ) / E]^2
Where:
n is the required sample size
Z is the Z-score corresponding to the desired confidence level (for a 95% confidence level, Z ≈ 1.96)
σ is the population standard deviation ($1,000 in this case)
E is the desired margin of error ($100 in this case)
Plugging in the values, we have:
n = [(1.96 * 1000) / 100]^2 = 3841.44
Since we can't have a fraction of a sample, we round up to the nearest whole number, resulting in a required sample size of 3,842.
However, since the economist already has a sample of 50 individuals, they would need an additional sample size of 3,842 - 50 = 3,792 to meet the desired criteria.

4 A home-decorating company is determining the amount of fabric required for a customer's window treatments. A single window requires 13 yards and a double 7 window requires 16, yards of fabric. If there are two single windows and one double window, how much fabric is required?
Answers
The solution will be that the home-decorating company will require 42 yards of fabric for the customer's window treatments.
As per the information we have received from the question,
A single window requires 13 yards and a double window requires 16 yards of fabric. We are asked to find out the length of fabric that will be required by the home-decorating company, in case there were 2 single windows and 1 double window. The total amount of fabric that will be required by the home-decorating company is hence equal to
13×(no of single windows)+ 16×(no of double windows)
Here, no of single windows= 2
And, no of double window= 1
Hence, total fabric length=13×2 + 16×1=26 + 16=42 yards
Hence the solution is 42 yards of fabric.

(B size)/(A size) = 3/2
The scale factor is 3/2.
__
Additional comment
Triangle B can be obtained from triangle A by dilation about the point (1, 1) using a scale factor of -3/2. The negative scale factor reflects the image across the center of dilation, in addition to changing its size.
The same effect can be achieved by dilation by a factor of 3/2, then rotating the figure 180° (or reflecting it across the x- and y-axes), and translating it to its final position.
Whether you call the scale factor 3/2 or -3/2 depends on how it fits into the transformation of ∆A to ∆B.
