There are 720 of such numbers that consists of five-digits which their product is 6! by permutation.
What is permutation?The mathematical term permutation can simply be defined as a process of arrangement or selection of objects. It involves each of several possible ways in which a set or number of things can be ordered or arranged.
We can apply the formula for permutation;
[tex]p(n,r) = \frac{n!}{(n - r)!} [/tex]
where n = total number of object and r = number of objects selected.
We can calculate the arrangement by applying the permutation formula as follows
[tex]p(6,5) = \frac{6!}{(6- 5)!}[/tex]
[tex]p(6,5) = \frac{6 \times 5 \times 4 \times 3 \times 2 \times 1}{1!}[/tex]
[tex]p(6,5) = \frac{720}{1}[/tex]
[tex]p(6,5) = 720[/tex]
Hence, with good application of the formula for permutation, we can say that there are 720 arrangement of such numbers which their product is 6!.

Step-by-step explanation:
Suppose that Randy is an analyst for the bicyling industry and wants to estimate the asking price of used entry-level road bikes
advertised online in the southeastern part of the United States. He obtains a random sample of n = 14 online advertisements of
entry-level road bikes. He determines that the mean price for these 14 bikes is x = $714.19 and that the sample standard
deviation is s = $184.56. He uses this information to construct a 99% confidence interval for µ, the mean price of a used road
bike.
What is the lower limit of this confidence interval? Please give your answer to the nearest cent.
What is the upper limit of this confidence interval? Please give your answer to the nearest cent.
1. The lower limit of this confidence interval is $587.13.
2. The upper limit of this confidence interval is $841.25.
How are the lower and upper limits determined?The lower limit describes the lowest price that entry-level road bikes will cost.
The upper limit refers to the highest price that entry-level road bikes can command.
Using the lower and upper limits, Randy can confidently estimate the range of the asking price of the used entry-level road bikes.
N = 14
Mean price, µ = $714.19
Sample deviation = $184.56
Confidence interval = 99%
The z-score of 99% confidence interval = 2.576
The margin of error = z-score x (standard deviation/√n)
= 2.576 x ($184.56/√14)
= $127.06
Lower Limit = µ - margin of error
= $714.19 - $127.06
= $587.13
Upper Limit = µ + margin of error
= $714.19 + $127.06
= $841.25
Thus, Randy can estimate that the price of used entry-level road bikes is $714.19 ±$127.06 at a 99% confidence level.

Graph the line that is parallel to the line
2x-3y = -9 and passes through the
point (-3, 5).
y = 2/3x + 7 is slope-intercept form of the equation .
What exactly does slope intercept mean?
A method of expressing a line's equation that makes it simple to identify the slope and y-intercept is known as the slope-intercept form.The point where the line is drawn the y-axis is known as the y-intercept, and the slope refers to how steep the line is.the equation of the parallel line in slope intercept form y=mx+b so that we can clearly see the slope and y intercept
2x-3y = -9
3y = 2x + 9
y = 2/3x + 9/3
y = 2/3x + 3
compare equation y = mx + c
slope = 2/3
to find c put x = -3 and y = 5
y = mx + c
5 = 2/3 * (-3) + c
5 = -6/3 + c
c = 5 + 2 = 7
put the final equation together

Carson Company has an inventory turnover of 13.00, and its inventory amounts to $5,000,000. What is the amount of cost of goods sold?
$6,50,000 is the cost of the goods sold.
What is Inventory turnover?By dividing a company's cost of sales, or cost of goods sold, by its inventory turnover, one can determine how well it uses its inventory (COGS).
The number of times inventory is sold or used over a given time frame, like a year, is referred to as the inventory turnover in accounting. It is calculated to determine whether a company has an excessive amount of inventory in relation to its level of sales.
Inventory turnover is the count of times a company's stock is sold during the course of a month, a quarter, or (most frequently) a year of business.
We should apply the following formula to calculate the cost of goods sold:
Cost of goods sold / inventory equals inventory turnover.
Rearranging the equation and replacing the unknown values results in:
Inventory plus inventory turnover equals cost of goods sold.
Price of items sold = $5,000,000 divided by 13
$6,50,000 is the cost of the goods sold.

y -----> the total cost
we have
budget rent a car
y=40x+45.95 ------> equation 1
Another company

The grouping of numbers by parentheses in a different way does not affect their product. Also, changing the order or position of the product of two numbers does not change the end result.
