hat is the public key

Which expression yields a random number between 11 and 26, inclusive? O (rand ()% 16) + 11 O rand () % 26 O (rand () % 15) + 11 O (rand () % 26) - 11

On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of fo* rn, where n is the distance (number of keys) from that key, and r is 2(1/12). Given an initial key frequency, output that frequency and the next 4 higher key frequencies. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print (f'{your_value1:.2f} {your_value2:.2f} {your_value3:.2f} {your_value4:.2f} {your_value5:.2f}') Ex: If the input is: 440 (which is the A key near the middle of a piano keyboard), the output is: 440.00 466.16 493.88 523.25 554.37 Note: Use one statement to compute r = 2(1/12) using the pow function (remember to import the math module). Then use that r in subsequent statements that use the formula fn = f0 * rn with n being 1, 2, 3, and finally 4. 461710.3116374.qx3zqy7 LAB ACTIVITY 1 22 2 2.16.1: LAB: Musical note frequencies Type your code here. 111 main.py 0/10 Load default template...

Elgamal public key cryptosystem (encryption): Start with the prime p = 17 and the primitive root g = 3. Alice sends Bob the public key A = 5. Bob wants to send the message m = 13 to Alice. Bob chooses the random element k = 2. Using the Elgamal public key cryptosystem, compute the pair of numbers (C₁, C₂) that Bob sends to Alice. Note: Do not work out how Alice computes the plaintext message m from the ciphertext (C₁, C₂).
