Consider the following symbols and their frequencies: a: 0.20, b: 0.10, c: 0.15, d: 0.25, e: 0.30 since b and c are the symbols of least weight, they are combined into a subtree, which we will call t1 for discussion purposes, of weight 0.10 + 0.15 = 0.25, with the larger weight symbol, c, on the left. now, the two trees of the smallest weight are the single symbol a and either t1 or the single symbol d (both have weight 0.25). we break the tie arbitrarily in favor of t1, so we get a tree t2 with left subtree t1 and right subtree a. if we continue constructing the tree as mentioned, the huffman codes of the symbols a, b, c, d, and e are as follows:

As part of an annual fundraiser to raise money for diabetes research, diane joined a bikeathon. the track she biked on was 1,920 yards long. diane biked 38.5 laps. her sponsors agreed to donate an amount of money for each mile she biked. how many miles did she bike? first fill in the blanks on the left side using the ratios shown. then write your answer. given ratios: 5280ft / 1 mi , 1 mi /5280 ft , 1,920 yards / 1 lap , 1 lap / 1,920 yards , 3 ft / 1 yard , 1 yard / 3 ft. blanks: 38.5 laps / 1 yard x (blank) x (blank) x (blank) = (blank) miles i'm really confused on how to do this, and the explanations aren't exactly . if you could walk me through how to do this, it would be greatly appreciated.
