Answer:
I find this question really interesting, and id love to give you my perspective on the pros of knowing how to calculate, discounts, sales taxs and
ect!
Explanation:
Why I believe it is important to know how to calculate on your own, there can be cases where an item is on sale for x% off, maybe a store clerk doesnt include the discount, by knowing how to calculate what percentage was supposed to be taken off of the item you can tell the clerk!
of if you were to work in a store you would need to calculate discounts too even though we have the technology doesnt mean it always works or is right, its a good back up!
There are many instances where, you being the costumer or clerk should know what discounts you are getting,or giving, its just percaution for the future!

The statement that describes the sampling distribution of the sample mean is: Approximately normal with mean $206,274 and standard deviation $3,788.
<h3>Sampling distribution of the sample mean </h3>
Using this formula
Standard deviation= Standard deviation /√Random sample
Where:
Standard deviation=$37,881
Random sample=100
Let plug in the formula
Standard deviation= $37,881/√100
Standard deviation=$37,881/10
Standard deviation=$3,788
Inconclusion the statement that describes the sampling distribution of the sample mean is: Approximately normal with mean $206,274 and standard deviation $3,788.

The volume of HCl gas required to prepare the solution is 101.54 L
<h3>How to determine the mole of HCl </h3>
- Volume of solution = 1.25 L
- Molarity = 3.20 M
- Mole of HCl =?
Mole = Molarity x Volume
Mole of HCl = 3.2 × 1.25
Mole of HCl = 4 moles
<h3>How to determine the volume of HCl </h3>
- Number of mole (n) = 4 moles
- Temperature (T) = 30 °C = 30 + 273 = 303 K
- Pressure (P) = 745 torr = 745 / 760 = 0.98 atm
- Gas constant (R) = 0.0821 atm.L/Kmol
Using the ideal gas equation, the volume of the HCl gas can be obtained as follow:
PV = nRT
Divide both side by P
V = nRT / P
V = (4 × 0.0821 × 303) / 0.98
V = 101.54 L

Answer:
The proportion of Pria's investment is $7000 / 6000+4000+7000 = 7 / 17
So, Pria's share of the profit is $12000 x 1/17 = $4941
So your answer is $4941
