* Please solve these problems in Excel on different worksheets in the same Excel file.1. A warehouse distributor of carpet faces a normally distributed demand for its carpet. The average demand for carpet from the stores that purchase from the distributor is 4,500 yards per month, with a standard deviation of 900 yards.a. Suppose the distributor keeps 6,000 yards of carpet in stock during a month. What is the probability that a customer’s order will not be met during a month? (This situation is referred to as a stockout.)b. What is the probability that the demand will be between 5000 and 7000 yards?c. How many yards of carpet should this warehouse distributor order from its supplier to ensure that 97% of the demand is met? (The percent of customer demand/orders satisfied is referred to as service level. In this question, the service level is 97%.)2. The state of Virginia has implemented a Standard of Learning (SOL) test that all public school students must pass before they can graduate from high school. A passing grade is 75. Montgomery County High School administrators want to gauge how well their students might do on the SOL test, but they don’t want to take the time to test the whole student population. Instead, they selected 20 students at random and gave them the test. The results are as follows:83 79 56 9348 92 37 4572 71 92 7166 83 81 8058 95 67 78Assume that SOL test scores are normally distributed.a. Compute the mean and standard deviation for these data.b. Determine the probability that a student at the high school will pass the test.c. How many percent of students will receive a score between 75 and 95?d. What score will put a student in the bottom 15% in SOL score among all students who take the test?e. What score will put a student in the top 2% in SOL score among all students who take the test?3. The average male drinks 2 L of water when active outdoors (with a standard deviation of 0.8L). You are planning a full day nature trip for 100 men and will bring 210 L of water. What is the probability that you will run out?
Consider the frictionless rod, i.e. β=0. The equation of motion becomesm (d^2 r)/(dt^2 )-mω^2 r=-mg sin(ωt)with g=9.81 m/s^2 and a constant angular speed ω.The rod is initially horizontal, and the initial conditions for the bead are r(0)=r_0 and r^′ (0)=v_0.A)Analytically solve this initial value problem for r(t) B)Consider the initial position to be zero, i.e. r_0=0. Find the initial velocity, v_0, that results in a solution, r(t), which displays simple harmonic motion, i.e. a solution that does not tend toward infinity. C)Explain why any initial velocity besides the one you found in part B) causes the bead to fly off the rod. D)Given r(t) displays simple harmonic motion, i.e. part B), find the minimum required length of the rod, L, as a function of the angular speed, ω. E)Suppose ω=2, graph the solutions, r(t), for the initial conditions given here: r_0=0 and initial velocities of v_0=2.40, 2.45, 2.50, and the initial velocity you found in part B). Use 0≤t≤5

There are two parts to this assignment. Part 1 involves the encryption/decryption scenario below and Part 2 requires research on the classification of ciphers, and popular algorithms.Part 1Use a two-stage transposition technique to encrypt the following message using the key “Decrypt”. Ignore the comma and the period in the message.Message: “The Transposition cipher technique works by permuting the letters of the plaintext. It is not very secure, but it is great for learning about cryptography.”In a 2–3 page summary, discuss the following:Is it possible to decrypt the message with a different key? Justify your answer.Do you agree with the statement of the message? Why or why not? Give at least two examples that support your view.Part 2Provide a 1–2-page researched responses to the following:Research and provide a detailed meaning for at least three techniques in which encryption algorithms can produce ciphertext. Pick at least 3 from the cipher list below:MonoialphabeticSteganographicPolyalphabeticPolygraphicRoute transpositionColumnar TranspositionSynchronous StreamAsynchronous Stream
