Until relatively recently, all money lenders were in the business of confounding their customers as to the true cost of borrowing money from them. This was because many people would have had serious doubts if they knew the total cost of borrowing, and the lenders would then lose business and their livelihood.
Around 40-50 years ago many governments, across the world, insisted that formal financial institutions were up front about their interest rates and confounding was significantly reduced. However, it continued, as before, in the unregulated sector - the loan sharks, for example. Often, interest over a short period was highlighted to conceal the annual rate. For example, 5% per week does not sound like much but it is more than 1000% over a year. So if you borrow GBP 100, you will have to pay back more than GBP 1100 a year later! The 5% was quoted to confoud, astound, nonplus you!
But, just in case you meant compound interest, this is interest that is charged not just on the capital but also on any interest accumulated from previous periods.
3.33 is the probable chance of landing on any sides of a dies if you roll it 20 times.
How do you calculate the frequency?
Count the number of events occurring during a time period. Then frequency = number of events/length of time period.
How do you derive Moment generating function of Pareto distribution?
The moment generating function for any real valued probability distribution is the expected value of e^tX provided that the expectation exists.
For the Type I Pareto distribution with tail index a, this is
a*[-x(m)t)^a*Gamma[-a, -x(m)t)] for t < 0, where x(m) is the scale parameter and represents the least possible positive value of X.
What does mean median mode and range mean 16 23 14 16 21 20?
The median is the middle number of any given set when they are in order, least to greatest. If there is an even number of values, the median is the average of the middle two.
Ex. (14, 16, 16, 20, 21, 23)
The median is 18.
In any given set, the mode is the number that appears most often. If no number appears more frequently than any other, there is no mode.
Ex. (14, 16, 16, 20, 21, 23)
The mode is 16.
In any given set, the range is the smallest number subtracted from the largest number.
Ex. (14, 16, 16, 20, 21, 23)
23 - 14 = 9
The range is 9.
In any given set, the mean is the average, which is the total of the numbers divided by how many numbers there are.
Ex. (14, 16, 16, 20, 21, 23)
14 + 16 + 16 + 20 + 21 + 23 = 110
There are 6 numbers in this set.
110/6 = 18 and 1/3
The mean is 18 and 1/3.
No.
What is the difference between the smallest and biggest numbers formed from digits 4 8 0 6 and 2?
If leading 0s are permitted, then
86420 - 02468 = 83952
else
86420 - 20468 = 65952
What are the more obscure types of charts excel provides?
There are charts that most people don't use, but would not be regarded as obscure for those that use them. Some are more specialised. XY (Scatter) charts are not very specialised but could be regarded as obscure. Area charts are unusual. Doughnut charts are variations of pie charts, but not commonly used. Radar charts, Surface charts and Bubble charts are very much associated with statistic. Stock charts, sometimes known as high-low-open-close charts, are used by people working on stocks and shares. Cylinder, Cone, or Pyramid charts are just variations on bar and column charts using different shapes.
When is census necessary instead of sampling?
census is conducted for group data so if it is a sampling data is taken it would lead to lot of non sampling errors
How many 3-digit numbers can be made using the digits 3 6 9?
-- If the same digit may be repeated, then 27 can be made.
-- If the same digit may not be repeated, then 6 can be made.

Many people do have the ability to interpret and analyze material and make well justified decisions from the analysis. These people usually work in very complex jobs.
