Answer:
the covariance is -0.0151
Explanation:
The computation of the covariance is given below:
= correlation coefficient × standard deviation of x × standard deviation of y
= -0.4 × 18% × 21%
= -0.0151
Hence, the covariance is -0.0151
We simply applied the above formula so that the correct value could come
Answer:
The statement is: True.
Explanation:
For accounting purposes, cash is defined as every monetary instrument that can easily be converted into actual cash. Those instruments can be <em>coins, currency, checks, money orders, bank drafts, </em>or <em>Certificates of Deposit (CD), </em>to mention a few. In its most basic essence, cash is the default medium of exchange for goods and services to be traded.
Buffer of inventory can absorb variations in flow rates by acting as a source of supply for a downstream step.
<h3>
What is a buffer?</h3>
- In manufacturing, a buffer is used to account for fluctuations in the production process. Consider a buffer as a means to guarantee that your production line will continue to function normally even if unexpected circumstances arise.
- Having enough supplies on hand to ensure smooth operations is one example of a buffer in manufacturing. To help stabilize any fluctuations they encounter with their supply and demand chains, production capabilities, and lead times, manufacturers will often keep inventories of the raw materials and supplies needed for production on hand, as well as occasionally inventories of finished goods awaiting shipment.
- Without the proper buffers, manufacturing procedures may sluggish, which would result in more costs and lower profitability.

Answer:
The yields with each alternative from 1-4 are as follows:
Alternative 1 189.63
Alternative 2 199.72
Alternative 3 199.58
Alternative 4 195.56
Since each alternative costs $15,000 ,the most cost-effective alternative is that which produces the highest output with the same cost of $15000
In other words, the most cost effective is alternative 2 with 199.72 output.
Find detailed computations in the attached spreadsheet.
Explanation:
In calculating the output in each case , the formula is:
Input*multiples of stages percentages.For instance in calculating the output for alternative 1 ,I have this:300*(89%*91%*94%*93%*93%*96%)=189.63
Answer:
(1) The planning value for the population standard deviation:
= 5,000
(2) Given a = 0.05, Z(0.025) = 1.96 (from standard normal table)
(a)
n = 384.16
(b)
n = 2,401
(c)
n = 9,604
(3) No, because the sample size of the study is too larger.
