You track your commute times for three weeks (15 days), recording the following times in minutes: 17, 16, 20, 24, 22, 15, 21, 25, 17, 90, 16, 17, 22, 20, 20. enter the data into a 3-by-5 matrix, where rows are weeks and columns are weekdays. answer the following questions and provide the necessary code. (a) name each column with the weekday abbreviations, i. e., mon, tue, wed, thu, and fri (b) find the shortest, the longest, the average, and the median commute time within those three weeks. (c) the 90 was a mistake. it should have been 19. how can you fix this? do so, and then find the new average and median. (d) how many times was your commute 20 minutes or more? (e) what percent of your commutes are less than 18 minutes long? (f) in average, which weekday you spend the most commute time?

You have learned about the six trigonometric functions, their definitions, how to use them, and how to represent them graphically. the sine, cosine, and tangent trigonometric functions can be paired with their reciprocal functions, cosecant, secant, and cotangent, respectively. think about how each function is related to its reciprocal function. how are the graphs of the reciprocal functions related to their corresponding original functions? what happens to the graphs of the reciprocal functions as x approaches the zeros of the original functions? describe how you would teach friends with different learning styles (visual-spatial, aural-auditory, verbal-linguistic, physical-bodily-kinesthetic, logical-mathematical, social-interpersonal, and solitary-intrapersonal) how to graph the reciprocal functions
