[Solved]1 Find Integers S T 172s 151t 1 Full Credit Find Smallest Magnitude Integers Hint First F Q37298493
1. Find integers s, t such that 172s + 151t == 1. For fullcredit, find the smallest magnitude integers you can. Hint: Firstfind gcd(151, 172) = 1.
2. (a) In lecture, we saw Euler’s Totient Function Φ(n), whichis defined as the number of positive integers less than or equal ton that are relatively prime to n. Suppose I want to compute Φ(84),as per lecture. I know that 84 = 14 × 6, so I compute Φ(14) andmultiply it by Φ(6). Do I get the right result? Briefly, why doesthis work or not work? Your answer should be brief, but not assimple as “because the numbers do/don’t multiply to form that.” (b)Compute Φ(84). Show your work.
3. Calculate 9200 mod 77. Show your work. For purposes ofshowing your work, do not assume you have access to a programmable(e.g., graphing) calculator or internet for purposes of solvingthis problem. To make this fair to all, we will tell you thecorrect number at the end is 67.

The encoding methods are used to address individual devices on a single network. b.) A form of data compression may be achieved with some of the encoding methods discussed c.) Both the data and a synchronizing clock are included on a single digital signal d.) Bit rates (measured in bits/second) can vary within a single encoded signal e.) Long sequences of the same bit level do not run the risk of losing clock synchronization. f.) Data is represented by the timing of changes in signal level and not the signal level itself.

[Solved]1 Following Correct Code Snippet Throwing Pair 12 Sided Dice Get Sum Numbers Two Dice 2 24 Q37206280
1.Which of the following is the correct code snippet forthrowing a pair of 12-sided dice to get a sum of the numbers on twodice between 2 and 24 with different probabilities
2 * (rand() % 11 + 2)
rand() % 23 + 2
(rand() % 12) + (rand() % 12)
(rand() % 12 + 1) + (rand() % 12 + 1)
2.What would be the correct replacement for the following if ()statement ?
if (0 > temperature > 212)
It is correct, no need to replace the statement.
if (0 > temperature && temperature > 212)
if (0 > temperature || temperature > 212)
if (0 > temperature and temperature > 212)
3.What, if anything, is syntactically wrong with the followingfunction definition?
int sign(int x) { if (x < 0) return -1; else if (x > 0) return 1; }
It should have a double argument, not an int.
If x == 0, neither return statement is executed.
The if() statement needs braces {}.
The code has no syntax errors.
4.What is calculated by the code snippet?
int n = 0;int x;while (cin >> x){ if (x > n) { n = x; }}
The average of the input values
The number of input values
The minimum value of all input values
