Answer: a) 59049, b) 15120, c) 126.
Step-by-step explanation:
Since we have given that
5 digit sequences from the integers 1,2,...9.
a) the digits can be the same.
Repetition is allowed.
So, Number of ways to form 5 digit sequences would be
b) the digits cannot be the same and the order in which they appear matters.
Repetition is not allowed and order is maintained, so we will use "Permutation":
c) the digits cannot be the same and the order in which they appear does not matter.
Repetition is not allowed and order is not maintained, so we will use "Combination":
Hence, a) 59049, b) 15120, c) 126.
Answer:
The increase in cost is $ 213750
Step-by-step explanation:
From the question we are told that
The marginal cost function is where
Since is in dollars it means that is the cost price and x is given as the number of bikes now to obtain for the given increase of the number of bikes we integrate within the increase limit
This can be evaluated as
$ 213750
