2. 3. 5. 6. How many even 4-digit numbers greater than 3000 can be formed from the digits 2, 6, 7, 8, 9 if no digit can be used more than once? Find the inverse s of -1959 modulo 979 such that 0 ≤s<979. You must show all the detailed steps. In a certain assembly plant, three machines, Machine 1, Machine 2 and Machine 3 make 30%, 45% and 25% respectively of the products. It is known from the quality control data collected from the past that 2%, 3% and 2% of the products made by each machine respectively, are defective. If a product is chosen randomly chosen and found to be defective, what is the probability that it is made by Machine 3? 5 people are to be chosen at random from 5 men and 4 women to form a team. Find the probability that the team contains (i) (ii) 3 men and 2 women, at least 3 men.

Question 2 : Consider the following functions: log2 x • x.log₂x (²9) ² X log₂ x • 2x • √x x² • (log₂ x)² (3) ² The aforementioned functions represent the number of operations carried out by a set of algo- rithms that solve the same computational problem in different ways. Your task it to order the functions from slowest to fastest asymptotic growth rate (i.e., sort the algorithms from best to worst in terms of runtime complexity). Explain your reasoning for each consecutively ordered function pair by using the limit method For example, given a set of three functions {f(n), g(n), h(n)}, if you claim that asymptotically f(n) < g(n) < h(n), then you must prove that limn→∞(n) = 0 and limn→∞ g(n) = 0.

I'm having a very difficult time understanding RSA and Euclid's Algo. I understand how to compute N, and I understand how to computer PHI. I get lost when trying to find integer e, such that gcd(e, PHI) = 1 and further. I also do not understand how to find A and B or where "79" and "-39" come from (i.e., 79 * 859 + (-39)1740 = 1). Can someone please explain this for me in the simplest terms possible?

7. For n 2 1, in how many out of the n! permutations T = (T(1), 7(2),..., 7 (n)) of the numbers {1, 2, ..., n} the value of 7(i) is either i – 1, or i, or i +1 for all 1 < i < n? Example: The permutation (21354) follows the rules while the permutation (21534) does not because 7(3) = 5. Hint: Find the answer for small n by checking all the permutations and then find the recursive formula depending on the possible values for 1(n).
