For presenting home library statistical data you could use a pie chart. The parts can be things like various genres, or based on writers, or anything similar. You could make a lot of different ones about various statistical data about books and it would still be the best choice.
There are two solutions for this problem. It depends if order matters or not. As asked in the problem, we have to show both solutions.
The first solution is for the condition that order does not matter. This is a combination problem:
nCr = n!/r!(n-r)!
where n=10 because there are 10 total students, and r=2 because you choose 2 students at a time
nCr = 10!/2!(10-2)! = 45 ways
The second solution is for the condition that order matters. This is a permutation problem.
nPr = n!/(n-r)! = 10!/(10-2)! = 90 ways
Answer:
5.5 meters above start position.
Step-by-step explanation:
-Let X be the start position.
#Total distance below the start position is calculated as:
#Total distance above the start position X:
#Distance above/below start position is:
Hence, The vessel is 5.5 meters above the start position
