Answer:
a) 39
b) 58
Explanation:
Data provided in the question:
Mean = $70
Standard deviation, s = $8
Number of households, n = 40
Now,
a) number of households whose monthly utility bills are between $54 and $86
z score for $54 = [ 54 - 70 ] ÷ 8 [ z score = [ X - mean ] ÷ s]
or
z score for $54 = -2
z score for $86 = [ 86 - 70 ] ÷ 8 [ z score = [ X - mean ] ÷ s]
or
z score for $54 = 2
Therefore,
P(between $54 and $86) = P(z = 2) - P(z = -2)
= 0.9772498 - 0.0227501
= 0.9544997
Therefore,
number of households whose monthly utility bills are between $54 and $86
= P(between $54 and $86) × n
= 0.9544997 × 40
= 38.18 ≈ 39
b) In a sample of 20 additional house i.e n' = 40 + 20 = 60
thus,
number of households whose monthly utility bills are between $54 and $86
= P(between $54 and $86) × n'
= 0.9544997 × 60
= 57.27 ≈ 58
Even though there was a miscommunication in the sale, Jones did not know that the stone was a diamond before selling it and Smith can easily say he did not know it was either. If Jones had taken the stone and received other opinions on it, he may have gotten more money but because he sold the stone, there is nothing he can take action on Smith for.
Answer:
FIFO.
Explanation:
Note: This question is not complete. The complete question is therefore given before answering the question as follows:
The inventory method that will always produce the same amount for cost of goods sold in a periodic inventory system as in a perpetual inventory system would be:
FIFO.
LIFO.
Weighted average.
None of these answer choices is correct.
The explanation to the answer is now given as follows:
First-in, first-out (FIFO) is an inventory method under which the oldest inventory items are recorded in the account as being issued or sold first.
A periodic inventory system refers to an inventory valuation method under which there is an update to the inventory account at the end of an accounting period instead of after every sale and purchase of inventory items.
A perpetual inventory system to an inventory valuation method under which there is an update to the inventory account after every sale and purchase of inventory items. This is done by using computer softwares such as computerized point-of-sale systems and enterprise asset management software.
When FIFO inventory method is being used, both the periodic inventory system and perpetual inventory system will always produce the same amount for cost of goods sold.
Based this explanation, the correct option for this question is FIFO.
Answer:
3.75
Explanation:
Given;
Price of gold = $1,200 per troy ounce
Price of silver = $20 per troy ounce
Therefore,
1200/20 = 60 pieces of silver is worth one troy ounce of gold but;
1 ounce = 0.0625 pounds
60 ounces = 60 ×0.0625
= 3.75
Therefore a 3.75 pounds of silver is worth single troy ounce of gold.
