What were Electronic Data Systems stock values in 1988 and 1990?
I am looking for the share prices for Electronic Data Syaytems in the years 1990 and 1988.
How many ways could you get a sum of 3 when two dice are thrown?
Two ways- one on the first die, and two on the second die, and visa versa.
How do you work out an average?
add all the numbers together and then you divide it by the number of numbers there are for example if you have 20, 10, and 30 they equal 60 and since there are 3 numbers you divde 60 by 3 and there you go you get 20
What are lines that fail to meet?
Lines that fail to meet must be Parallel Lines. Parallel lines are lines which go in exactly the same direction. A bit like and equals sign. (=) the lines aren't supposed to meet, and they could go on forever, but still would never meet. An example of this would be train tracks. If the tracks were to come any closer or further apart, the train would not move on the tracks.
Can you make a 4banger in to a v6 in an Alero and what all would it take?
Change engines. It would take a donor car and lots of work by someone who knew what they were doing. Forget going that route. Sell the 4 cylinder and buy a V6 if that is what you want.
What are the measurements that fall beyond three standard deviations from the mean?
They are observations with a low likelihood of occurrence. They may be called outliers but there is no agreed definition for outliers.
What is the calulated value of the standard deviation of returns for -22.0 -2.0 20.0 35.0 and 50.0?
It is 28.73
Vasilka is one of the similar woman names like Vasilissa and Vasiliki. I think that Vasilka is mostly used in Bulgaria but also in other Balkan countries, and Vasilissa mostly in Russia. Vasiliki is the Greek name. All of them mean ''the royal one'' or ''the Queen'' and the name comes from the Greek word ''Βασιλεύς'' (pronounced Vasilefs) or ''Βασιλιάς'' (pronounced Vasilias). The same name for the men is ''Vasilis''.
If the true value is 21.751 grams what is the absolute error and the percent error?
In order to determine the absolute error of this you would have to have a measurement or an estimate of whatever this object is. at which point you would take the difference between the two.
For example: 21.571 is the True value 20.000 is the Recorded Value.
Thus: (True value) - (Recorded Value) = Absolute error (21.571) - (20.000) = 1.571
To determine the Percent value, applying the skills learned above, it is represented by the following equation
(Recorded value - True value) / True value*100%
(20.000 - 21.571) / 21.751*100% = -7.28%
It is possible to have multiple points of absolute error for instance. If you have 3 measurements one above the true value, the true value, and one below the true value. (e.g 20, 21.571, 22.571) can be represented as +/- 1.571g
How can you find the total number of 4-number combinations possible from digits 1-7?
*inclusive: 74 = 2401 *exclusive: 7*6*5*4 = 840
What is the most common three digit number won in Thailand loterry?
Actually the most common winning three digit numbers in the Thailand lotto are 231, 453 and 234
How many different 8 digit numbers are there for numbers 0 -9?
They're all the counting numbers from 10,000,000 to 99,999,999 .
That's all the counting numbers up to 99,999,999 (100 million of them) minus
the first 9,999,999 (10 million of them), and that leaves 90 million .
What is one important consequence of reducing standard error of the mean?
Estimates of the mean are then more reliable.
What is the difference between the number value and the face value of 7 in 857432?
7000 (number value) - 7 (face value) = 6993.
How many tiles 10 centimeters by 10 centimeters fit into an area of 10 meters by 20 meters?
The area of the tile (10 cm x 10 cm) = 0.1 m x 0.1 m = 0.01 m², so it takes 100 tiles to make a square meter. There are 200 m² in 10 m by 20 m, so you need 20000 tiles (20 thousand)
What is the greatest six digit even numbers with no repeated digits?
For this kind of question, start from the left, and use the greatest possible digit for each position. Thus, in the first position you would have a 9, in the second an 8, etc.
The maximum likelihood estimate, possibly.
What are the steps for mean median and mode?
Mean = sum of observations/number of observations
Median: Order the observations. Of there are an odd number of observations, the median is the middle one. So if there are n observations (where n is odd) then the median is the (n+1)/2 th observation. If n is even, the median is the average of the n/2 th observation and the (n/2 +1) th.
Mode: Group the observations. The mode is the value or values that appear the most often. There may be no mode, a single mode or lots of them.
What is the probabiltiy of landing on a number with 3 factors on a spinner with 8 possible outcomes?
The answer will depend on what the 8 numbers on the spinner are!
