With (n) things to choose from, and you choose a quantity (r) of them [like a lottery]: the formula is: n! / (r!(n-r)!) See related link.

How many combinations to make 40 by using the numbers 12 and 4?

To find the number of combinations to make 40 using the numbers 12 and 4, we can use a mathematical approach. Since we are looking for combinations, not permutations, we need to consider both the order and repetition of the numbers. One way to approach this is by using a recursive formula or dynamic programming to systematically calculate the combinations. Another approach is to use generating functions to represent the problem and then find the coefficient of the term corresponding to 40 in the expansion of the generating function. Both methods require a deep understanding of combinatorics and mathematical algorithms to accurately determine the number of combinations.

How many ways to make 75?

To determine the number of ways to make 75, we need more context. Are we looking at different combinations of numbers, or are we considering factors or multiples of 75? If we are looking at combinations, we could use a partition function or dynamic programming to calculate the number of ways. If we are considering factors or multiples, we would need to find all the factors of 75 and calculate the combinations from there.


How did Kepler decide to use an elliptic shape for his orbits It was the mathematical formula which matched the development of the new invention of the orrery. The ellipse was a mathematical function?

The ellipse is not a mathematical function because all but two values of the independent variable in the domain are mapped to two different points. The relationship is, therefore, one-to-many which means that it is not a function.


How many combinations of coins can make one pound?

To determine the number of combinations of coins that can make one pound, we must consider the various denominations of coins in circulation. In the British currency system, there are eight common coins: 1p, 2p, 5p, 10p, 20p, 50p, £1, and £2. To calculate the number of combinations, we can use a mathematical approach called the "coin change problem," which involves dynamic programming to efficiently compute the possible combinations. The exact number of combinations would depend on the specific constraints and parameters set for the problem.


What does the nCr function calculate?

The nCr function calculates the number of combinations of n items taken r at a time, where the order of selection does not matter. It is mathematically expressed as n! / (r! * (n - r)!), where "!" denotes factorial. This function is commonly used in combinatorics, probability, and statistics to determine how many different groups can be formed from a larger set.


What formula can you input into excel to come up with all the 5 number different combinations for numbers 1-39?

There is no built in function in Excel to create a list of combinations of 39 items taken 5 at a time. However, the combin function will tell you how many combinations there are. For instance, combin(39,5) = 575757.
