According to this great research...

"Number of U.S. households powered for 1 day by the electricity consumed for a single transaction"

6.56 homes

I am wondering what the $$ cash value this much electricity is?

Thanks

I would like to know how to compute the x-intercepts of a cubic graph based in a given equation. If there is a formula that does this, then i would like to know this formula, if not then i would like to know the steps required to compute said values.

If I remember correctly hen I was sitting in math classes a long time ago, there was a simple rule to establish the number of decimals needed to keep accuracy.

My problem is that I have a number of units and a price (resulting in a market value).

For example, if I have 3,976,796.834 units and the price is 10.052580533713, the resulting MV will be 39,977,070.4400.

Now I need to define how many digits I will need to keep (and I cannot keep 12) in order to keep the most accurate value.

What is the answer for this question

Hi,  I am looking to design a profit sharing scheme that would take into account the job level of the employee, the performance of the geographic region, and the individual performance level.  The first can be a number between 1 and 7 or a dollar amount, the second will be the achievement of projected profit, and the third will be a number between 1 and 5.  Is there anyway to calculate a final contribution without making it the percentage of a cap?  The total pool for each geographic regional will be a straight percentage of profits.

i.e. 15% of profits might be 10 million for ease of calculation.  For thirty employees, is there some formula that will reward each employee a portion of that 10 million based on their job level, achievement of projected profit, and ind. performance???

Thank you!

A relative told me bitcoin mining doesn't require us to pay anything, virtually 0 risk
& we get decent returns from it.  

1. Anyone can point me to articles (for newbie) on how to get started

2. Is it truly low-risk or no-risk?

I am wondering if anyone has any feeling for the error rate on any of:

- Iris scans
- Face recognition
- Finger print

I was just wondering...

Thanks

I am new to reading up on BitCoin but was fascinated to be reminded that in the early days of BitCoin, people "mined" additional BitCoin on their PC's. As far as I recall, this was in exchange to turning over part of the processing power of their PC's to BitCoin for background processing.

I assume this amounted to a massive amount of additional processing power available to BitCoin.

Does anyone recall the primary uses of that kind of processing horsepower?

Why do they not need this today?

Can computers today perform at such a higher rates, this "mining" is no longer needed?

Could the addition of a BlockChain database have removed the need for this kind of processing?

Thanks

Stupid question, please see attached.  When measuring the actual shortest distance between SFO to Amsterdam is shows 5,425mi.  The airplane route shows longer 10k+ miles.   Why wouldn't the flight goes the shortest distance?  Or is it how the distance vs measurement shows on the map just for user's simplicity?  

Hi everyone. How do I model this in Excel? It isn't a homework question, but a real life example of why they made you do these types of problem in math class.

I am borrowing $30000 to buy a car. There is an option available to get 0% financing, but only for 24 months, which would make a monthly payment of $1250. I also have access to a line of credit which has an rate of 3.5%. Currently I have $500 per month I can pay from my account. What would total cost of borrowing be if I took the 0% loan, paid $500 a month from my account and the remaining $750 from the line of credit. Then after 24 months, I would then use the $500/mo from my account to pay back the line of credit.

I have attached a spreadsheet showing the cost of just financing the whole thing on LoC vs the cost of the above in two stages. Just wanted to be sure that it is correct.

Dear experts:
Can someone please help me clarify the criteria to determine n and r in Permutations and combination. I think I am solving these problems by thumb rule rather on a proper understanding.
Below I have listed a few questions along with solutions where r is greater than n or i am not sure how allocate n ways to r blanks. Please help.

We know that the number of ways of filling up r blanks with n dissimilar things is nPr. The first blank can be filled with any one of the given n things in n ways.
Below I have a few examples:
Q1 In how many ways can 7 women go to 9 restaurants?
      1      2      3      4      5      6      7      8      9      
R blanks                                                            
N ways                                                            
The Permutation given is 97
Clarification: How do I determine which is n and which is r?

Q2 In an examination paper there are 8 questions each with 4 answer choices and 5 questions each with 2 answer choices. The no. of ways of answering the question if all the 13 questions are attempted is?
The Permutation given is 48 * 25
Clarification: How do I determine which is n and which is r?
Q3 In how many ways can 5 letters be posted in 6 boxes?
The Permutation given is 65
Clarification: How do I determine which is n and which is r?

Please help. Thank you
