Accounting procedures allow a business to evaluate their inventory costs based on two methods: LIFO (Last In First Out) or FIFO
ivanzaharov [21]

Answer: The FIFO method result in lower cost of inventory than the LIFO method.

Step-by-step explanation:

In the FIFO method old inventories are used to determine cost of goods sold (COGS), which result to less income because COGS is lesser, while it is greater in LIFO.

However, in LIFO, old and outdated inventories are valued lower than the present price. It not a good indicator of ending inventory value.

B. To calculate the degree of freedom of the inventory sample given: 1. 225221, 2. 119100, 3. 100113, 4. 212200, 5. 248245.

STEP 1. Find the mean or average of the samples.

Let x be the sample average, and N the sample size which is 5

x = 225221 + 119100 + 100113 + 212200 + 248245/5 = 180975.8

STEP 2. Degree of freedom Df is given as Df = N - 1

Remember, N is the sample size given as 5.

Df = 5 - 1 = 4.

CONCLUSION:

This shows that four numbers from the samples given have the freedom to vary as long as the average remains 180975.8.

Nate is recording what kinds of shoes people are wearing at the mall. He has seen 12 people wearing sneakers and 64 people weari
Stella [2.4K]

Answer:

Step-by-step explanation:

Remark

The total number of people he has surveyed is 12 +  64 = 76

So your probability is 12 / 76

When turned into a percent, the fraction becomes 100 times 12/76.

Givens

12 wore sneakers

64 wore other shoes

76 total in survey

Solution

P(sneakers) = # sneakers / Total

P(sneakers) = 12 / 76 = 0.15789

P(sneakers as a %) = 0.15789 * 100 = 15.789%

Answer

<em>P(sneakers %) = 15.8 rounded to nearest 1/10</em>
