LeoThis is a quick but fun problem.Alice collected some weather data and Bob collected some weight data of teenagers.They collected 6 data sets of 40 samples each. But they forgot to label which sets contain Alice's data and which sets contain Bob's.Alice knows that set A came from her weather data, and Bob remembers that set B is one of his weights samples.Can you work out which other lists belong to Alice, and which belong to Bob?<a href="https://nrich.maths.org/problems/which-list-which" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://nrich.maths.org/problems/which-list-which</a><a href="https://masto.gkbrk.com/tags/Math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Math</a> <a href="https://masto.gkbrk.com/tags/Maths" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Maths</a> <a href="https://masto.gkbrk.com/tags/Statistics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Statistics</a> <a href="https://masto.gkbrk.com/tags/Stats" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Stats</a>

CyanCqueakMy son pulled out a textbook at his tutoring centre and asked me to do this question.Moving past the odd statement that the object is at rest when the forces aren't balanced, when I resolve the weight of the I get a net force along the slope of 2N, assuming a friction coefficient of 0.The friction coefficient would need to be greater than 1 for the object to be at rest with the initial applied forces.Textbook says the answer is 0.
