A line graph is a great tool for showing changes over time. Why is a line graph better than other graphs at showing this type of data?

7. design a circuit with three inputs (x, y, and z) representing the bits in a binary number, and three outputs (a, b, and c) also representing bits in a binary number. when the input is 1, 2, or 3, the binary output should be one lesser than the input. when the input is 4, 5, or 6, the binary output should be one greater than the input. when the input is 0, the output is 0, and when the input is 7, the output is 7. show your truth table, all computations for simplification, and the final circuit.

Evaluate the following code segment. what is the value of count after execution? int count = 1; for(int outer = 0; outer < 4; outer++) for(int inner = 1; inner < 3; inner++) count++; 1 3 9 12 13

Which of the following exceptions could occur when the following code is run, if the precondition is met? // precondition: a is not null public string dosomething(arraylist a, int b) { int i; string s; for (i = 0; i < = a.size(); i++) { s = (string)(a.get(i)); if (s.length() == b) { return s; } } return null; }
