Determine the optimal decision tree for finding the (lower) median of six numbers a, b, c, d, e and f, with the additional assumption that among these numbers there are exactly three distinct numbers, each occurring exactly twice. In zoom lecture we denoted the height of the optimal decision tree by (2, 2, 2).

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
