A store has clearance items that have been marked down by 50%. They are having a sale, advertising an additional 45% off clearance items. What percent of the original price do you end up paying?
bTo determine the percent of the original price you end up paying after the discounts, we can calculate the final price as a percentage of the original price.
Let's assume the original price of an item is $100.
The first discount reduces the price by 50%, so the price after the first discount is 50% of the original price, which is $100 * 0.5 = $50.
The second discount of 45% is applied to the price after the first discount. The price after the second discount is 45% of $50, which is $50 * 0.45 = $22.50.
Therefore, the final price you end up paying after both discounts is $22.50.\
To find the percent of the original price you end up paying, we divide the final price by the original price and multiply by 100:
Percent of original price = (final price / original price) * 100
In this case, the final price is $22.50 and the original price is $100:
Percent of original price = ($22.50 / $100) * 100
= 0.225 * 100
= 22.5%
Therefore, you end up paying 22.5% of the original price after the discounts.
It's important to note that the percent of the original price you end up paying will depend on the original price of the item. The calculations above were based on the assumption that the original price was $100. If the original price is different, the resulting percentage will vary accordingly.

A statistics practitioner would like to estimate a population mean to within 50 units with 99% confidence given that the population standard deviation is 250. What sample size should be used? b. Re-do part (a) changing the standard deviation to 50. c. Re-do part (a) using a 95% confidence leve
Answer:
(a) 167
(b) 7
(c) 97
Step-by-step explanation:
The (1 - α)% confidence interval for the population mean μ is:
\(CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}\)
The margin of error is:
\(MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}\)
Then the formula to estimate the sample size is:
\(n=[\frac{z_{\alpha/2}\cdot \sigma }{MOE}]^{2}\)
(a)
For 99% confidence interval the critical value of z is:
z = 2.58.
The standard deviation is, 250.
Compute the sample size as follows:
\(n=[\frac{z_{\alpha/2}\cdot \sigma }{MOE}]^{2}\)
\(=[\frac{2.58\times 250}{50}]^{2}\\\\=(12.9)^{2}\\\\=166.41\\\\\approx 167\)
The sample size that should be used is 167.
(b)
Now the standard deviation is, 50.
Compute the sample size as follows:
\(n=[\frac{z_{\alpha/2}\cdot \sigma }{MOE}]^{2}\)
\(=[\frac{2.58\times 50}{50}]^{2}\\\\=(2.58)^{2}\\\\=6.6564\\\\\approx 7\)
The sample size that should be used is 7.
(c)
Now a 95% confidence level is used.
For 95% confidence interval the critical value of z is:
z = 1.96.
Compute the sample size as follows:
\(n=[\frac{z_{\alpha/2}\cdot \sigma }{MOE}]^{2}\)
\(=[\frac{1.96\times 250}{50}]^{2}\\\\=(9.8)^{2}\\\\=96.04\\\\\approx 97\)
The sample size that should be used is 97.

The basic rate pay is K8.20. If the overtime is paid at time-and-a-quarter, what is the overtime rate of pay?
The overtime rate of pay is K10.25.
The overtime rate of pay can be calculated by multiplying the basic rate pay by the time-and-a-quarter factor. In this case, the basic rate pay is K8.20.
To determine the overtime rate of pay, we need to calculate one-quarter (1/4) of the basic rate pay, and then add that amount to the basic rate pay. One-quarter of K8.20 is calculated as (1/4) * K8.20 = K2.05.
By adding the calculated overtime amount to the basic rate pay, we get the overtime rate of pay: K8.20 + K2.05 = K10.25.
Therefore, the overtime rate of pay is K10.25.

ABC Computer Company has a AED20, 000,000 factory in Sharjah. During the current year, ABC builds AED2,000,000 worth of computer components. ABC’s costs are labour AED 1,000,000; interest on debt, AED100,000; and taxes, AED200,000. ABC sells all its output to Jumbo LLC Supercomputer. Using ABC’s components, Jumbo builds four supercomputers at a cost of AED800,000 each (AED500,000 worth of components, AED200,000 in labour costs, and AED100,000 in taxes per computer). Jumbo LLC has a AED30,000,000 factory. JUMBO LLC. sells three of the supercomputers for AED1,000,000 each; at year’s end, it has not sold the fourth. The unsold computer is carried on JUMBO LLC’s books as an AED800,000 increase in inventory. a) Calculate the contributions to GDP of these transactions, showing that all three approaches give the same answer. and its explanation
All three approaches yield the same result: AED4,600,000 (Expenditure Approach), AED1,600,000 (Income Approach), and AED1,800,000 (Production Approach). This consistency demonstrates that the three approaches provide equivalent measures of GDP.
To calculate the contributions to GDP of the given transactions, we can use the three approaches: the expenditure approach, income approach, and production approach. Let's calculate the GDP using each approach and demonstrate that they give the same answer.
Expenditure Approach:
GDP is calculated as the sum of all final expenditures. In this case, the final expenditures are the sales of the supercomputers.
GDP = Sales of supercomputers
= (3 * AED1,000,000) + (1 * AED800,000)
= AED3,800,000 + AED800,000
= AED4,600,000
Income Approach:
GDP can also be calculated by summing up all the incomes earned during production. In this case, the incomes include wages, interest, and taxes.
GDP = Wages + Interest + Taxes
= (Labour costs for ABC + Labour costs for Jumbo) + (Interest on debt for ABC) + (Taxes for ABC + Taxes for Jumbo)
= (AED1,000,000 + AED200,000) + AED100,000 + (AED200,000 + AED100,000)
= AED1,200,000 + AED100,000 + AED300,000
= AED1,600,000
Production Approach:
GDP can also be calculated by summing the value added at each stage of production. In this case, the value added is the sales price minus the cost of components purchased.
GDP = Sales price of supercomputers - Cost of components
= (3 * AED1,000,000) + (1 * AED800,000) - (4 * AED500,000)
= AED3,000,000 + AED800,000 - AED2,000,000
= AED1,800,000
As we can see, all three approaches yield the same result: AED4,600,000 (Expenditure Approach), AED1,600,000 (Income Approach), and AED1,800,000 (Production Approach). This consistency demonstrates that the three approaches provide equivalent measures of GDP.

Step-by-step explanation:
The graph of a cubic polynomial function
has horizontal tangent lines at (1, −2) and (−1, 2). Find
an equation for the function and sketch its graph.
Answer: A cubic polynomial function has the form f(x) = ax^3 + bx^2 + cx + d.
A horizontal tangent line is a line that is parallel to the x-axis and it occurs at a critical point of the function, where the derivative of the function is 0.
We know that a cubic function has 3 critical points and thus 3 derivative that could be 0, so to find the equation of the cubic function we will use these two points to find the value of a, b, c, and d.
We know that the critical points of a cubic function are found by solving f'(x) = 0, where f'(x) is the derivative of the function, so we have:
f'(x) = 3ax^2 + 2bx + c = 0
Now we can use the two points to find the value of a, b, c, and d.
We know that the point (1,-2) is on the graph of the function, so we can substitute it into the equation to find d:
f(1) = a + b + c + d = -2
And we know that the point (-1,2) is on the graph of the function, so we can substitute it into the equation to find d:
f(-1) = -a + b - c + d = 2
Now we can use these two equations to find the value of a, b, and c:
a + b + c + d = -2
-a + b - c + d = 2
2a + 2d = 0
a = -d
-a + b - c + d = 2
b - c = 4
3ax^2 + 2bx + c = 0
3(-d)x^2 + 2bx - c = 0
Now we can use these equations and the critical points to find the value of a, b, c, and d
3(-d)x^2 + 2bx - c = 0, (1,-2) => 3d+2b-c = 0
3(-d)x^2 + 2bx - c = 0, (-1,2) => 3d-2b+c = 0
b-c = 4
Solving these equations, we have:
a = -1/3
b = 1
c = -5/3
d = -2
And the equation for the function is:
f(x) = -1/3x^3 + x^2 - 5/3x - 2
We can now sketch the graph of the function by using the information that we have. The cubic function will have an vertex of symmetry at (0,-2) and two horizontal tangent lines at (1,-2) and (-1,2) .
Since a < 0, the function is concave down, so the graph will be opened downwards and will have a local minimum at (0,-2) .
It is important to note that this is one possible equation for a cubic function that has horizontal tangent lines at (1, −2) and (−1, 2), but there may be other possibilities.

Enseñanza Básica is the term used to describe the first level of education in the Chilean education system, which includes the first to eighth grades. A teacher of Enseñanza Básica asked his students to choose three-digit mixed numbers that can be formed.
A mixed number is a number that has both a whole number and a fraction component. To form three-digit mixed numbers, we need to have a whole number that is less than 100 and a proper fraction that has a denominator less than or equal to 99. Here are some examples:123 4/567 2/8109 1/2382 3/47There are a total of 900 three-digit numbers that can be formed using digits 1 to 9 without repetition. To find the number of three-digit mixed numbers that can be formed, we need to count the number of ways we can choose a proper fraction with a denominator less than or equal to 99. There are 99 possible denominators, and for each denominator, there are 98 possible numerators (excluding 0 and the denominator itself). Therefore, the total number of three-digit mixed numbers that can be formed is:900 x 99 x 98 = 8,334,600There are 8,334,600 three-digit mixed numbers that can be formed using digits 1 to 9 without repetition.For such more question on fraction

Carlos is working two summer jobs, making $6 per hour walking dogs and making
$11 per hour clearing tables. In a given week, he can work no more than 14 total hours
and must earn no less than $110. If a represents the number of hours walking dogs
and y represents the number of hours clearing tables, write and solve a system of
inequalities graphically and determine one possible solution.
The system of inequalities graphically is given above.
One possible solution is (8.8, 5.2).
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
x = represents the number of hours walking dogs.
y = represents the number of hours clearing tables.
Now,
$6 per hour = walking dogs and making
$11 per hour = clearing tables.
Now,
No more than 14 total hours and must earn no less than $110.
We can make two inequalities.
x + y ≤ 14
6x + 11y ≥ 110
The graph is given below.
The intersection point from the graph is the one solution.
i.e
(8.8, 5.2)
or
x + y = 14
x = 14 - y
Substituting in 6x + 11y = 110.
6 (14 - y) + 11y = 110
84 - 6y + 11y = 110
5y = 110 - 84
5y = 26
y = 5.2
And,
x = 14 - 5.2
x = 8.8

a salesman earns 25% commission he sells amount to 2450 shillings after giving a buyers 2% discount . calculate his commission. Suppose all the goods were sold at marked price , what would be is earnings?
Answer:
Step-by-step explanation:
A) Commission = 2450 shillings * 25 % = 2450 shillings * (25/100) = 2450 shillings * (0.25) = 612.50 shillings
Commission = 612.50 shillings
B) If the total sale is 2,450.00 shillings, after the seller gives buyers a 2% discount. We must re-enter the discount:
2,450.00 shillings = X - X * 2% = X - 0.02 X --->
------> 0.98 X = 2,450.00 shillings
------>X= 2,450.00 / 0.98
------> X = 2,500.00 shillings
NEW COMMISSION = 2,500.00 shillings * 25 % = 2,500.00 shillings *(25/100) =2,500.00 shillings * (0.25) = 625 shillings
NEW COMMISSION = 625 shillings
