Record 7 digits (0-9) in ascending order that have a mean of 3 and a median of 1.
Explain how to come up with the answer as well please and thank you.
Mean = ∑x/n
3 = ∑x/7
∑x = 21, so the 7 digits must add to 21.
Half must be ≥ 1 and half ≤ 1, the median.
I assume you can have digits repeated. Seems like you will have multiples of 0 and/or 1.
You will have to explore the alternatives, but this should give you a start.
