Why is there exclamation points in some math problems?
The exclamation point is the symbol for the factorial function. For integer values of n, n! = 1*2*3*...*n The factorial is critical for calculating numbers of permutations and combinations.
How many ways can 9 people be seated if 3 chairs are available?
If the order is important, then: 9 choices for the first chair, 8 choices for the second, and 7 choices for the third = 9 x 8 x 7 = 504 ways. If order doesn't matter, then once you've picked 3 people, there are 6 ways to arrange them in the chairs, so divide by 6, or 84 ways.See related link on combinations and permutations for more information on these types of problems.
What multiplication problem equals 94?
There are two multiplication problems that equal 94 (not counting negative numbers): 1 x 94 = 94 2 x 47 = 94
What is 4B4B data mapping?
Perhaps you mean 4B5B? That's a way to assign combinations of 5 bits to every combination of 4 bits, in such a way that you avoid transmitting long strings of only zeros or only ones. This avoids synchronization problems.
What steps should be followed when solving problems in community care?
· Identify the problem · Define the problem · Collect data relating to the problem · Develop a range of alternative solution or combinations of solutions · Implement the solution · Check to ensure that the desired result has been achieved

How many ways can 9 books be arranged on a shelf so that 5 of the books are always together?
You can simplify the problem by considering it as two different problems. The first involves consider the five-book chunk as a single book, and calculating the permutations there. The second involves the permutations of the books within the five-book block. Multiplying these together gives you the total permutations. Permutations of five objects is 5!, five gives 5!, so the total permutations are: 5!5! = 5*5*4*4*3*3*2*2 = 263252 = 14,400 permutations
What is the trick of solving the problems of counting the number of figures in mental ability?
There are different tricks for different problems.
How do you use math in everyday life?
Counting days in the month, counting money, money problems etc and time. I'm sure there are plenty more.
How do you work out the probability of dice problems?
Count the number of permutations of the expected results and divide by the number of permutations of the possible results. This is standard probability theory, and it applies to everything in probability, not just dice.For instance, with two dice, there are 36 possible permutations, while there is only 1 permutation that adds up to a sum of 2, though there are 6 permutations that add up to a sum of 7. As a result, the probability of rolling a sum of 2 is 1 in 36, while rolling a 7 is 6 in 36, or 1 in 6.
What is a Roman counting board?
The roman counting board used to solve problems in mathematics was called abacus [άβαξ, in the Greek language]
What is the California law requiring accuracy in counting votes?
California is very accurate in counting votes. At the polls the people are well trained in handling ballots and particular problems that may arise.
What has the author Nancy Gail Kinnersley written?
Nancy Gail Kinnersley has written: 'Obstruction set isolation for layout permutation problems' -- subject(s): Very large scale integration, Permutations, Integrated circuits
Where there any problems associated withthe roman counting system?
The Romans themselves didn't encounter any problems with their counting system which was in use for over a thousand years. It only is today that people have problems with the Roman numeral system because it doesn't contain a nought figure for positional place value purposes but the positional place value of these numerals are self evident so a nought figure is not needed.

Think of people and their problems between you and that person. It is proven to get you to sleep quickly.
Where can I hear other people's opinions on eating out and not following my at-home diet versus eating out and ordering off the diet menu?
I have found that the best place to find people's opinions about unique topics in diet and weight loss, such as online forums that reference diet menus in restaurants, are calorie-counting weight loss websites like MyFitnessPal.com, where everyone tries to lose weight and networks to find solutions to everyday problems.
