Can anybody help me solve this problem? Here it is:
A matrix has 10 rows (labelled "A" to "J") and 10 columns (Labelled "1" to "10")
Each row represents a different feature of a car: For example, A = Maximum Speed; B = Fuel Efficiency; C = Safety, etc. An engineer designing a car can prioritize these features in order of importance from highest to lowest priority. Therefore the list of features will always consist of 10 letters, but they can be in any sequence.
Furthermore, for each of the 10 features, the engineer needs to specify "how much" of that feature will be included in the design, on a scale of 1 to 10. For example, Feature A = 8; Feature B = 5; Feature C = 9, etc. Remember that the rows with the features A to J can be ordered in any sequence, and each row can have any value between 1 and 10.
The question is, how many different 10 x 10 matrices are possible?
Thank you!
