The coins (UsingR) dataset describes coins in the author's change bin with year and value. Do not use explicit loops for any calculations. Do not hard code the denominations in the solution. The solution should work for any denominations. a) How many coins are there of each denomination? b) What is the total value of the coins for each denomination? c) What is the total value of all the coins made year 2002? d) Show the barplot for the total value of coins by year

Assume that minutes is an int variable whose value is 0 or positive. write an expression whose value is "undercooked" or "soft-boiled" or "medium-boiled" or "hard-boiled" or "overcooked" based on the value of minutes. in particular: if the value of minutes is less than 2 the expression's value is "undercooked"; 2-4 would be a "soft-boiled", 5-7 would be "medium-boiled", 8-11 would be "hard-boiled" and 12 or more would be a "overcooked".
