Layla is working on a PhD in computer science and wonders what the average page ner field. She takes a random sample of 80 computer science dissertations and notices that the distrībution of cheir page lengths is skewed to the right with high outliers and a sample mean of = 125.4 pages. She's considering using her data to make a confidence interval for the mean page length of computer science dissertations. Which conditions for constructingatinterval have been met? Choose all answers that apply: The data is a random sample from the population of interest. The sampling distribution of I is approximately normal. Individual observations can be considered independent.

What is the recurrence relation of maximum subarray sum problem by using Divide and Conquer approach CHOOSE ANY ONE OPTION 1.T(n) = 7T(n/2) + n 2.T(n) = 8T(n/2) + n 3.T(n) = 2T(n/2) + n 4.T(n) = T(n/2) + n
One way to avoid Runge's problem is to choose non-equally spaced data points. A particularly good set to choose are the so-called Chebyshev nodes. To use these, replace the equidistant points xk produced by xeq with xk = COS 2k+1 2n+2 for k=0,..., n. (3.4) Generate data points using (3.4) and (3.3), then plot the resulting Lagrange interpolating polynomial and, hence, show that using (3.4) solves the Runge problem.
Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. You're given a cluster b of length n. How about we characterize another cluster a, likewise of length n, for which ai=2bi (1≤i≤n). Valerii says that each two non-meeting subarrays of a have various amounts of components. You need to decide whether he isn't right. All the more officially, you want to decide whether there exist four integers l1,r1,l2,r2 that fulfill the accompanying conditions: 1≤l1≤r1<l2≤r2≤n; al1+al1+1+… +ar1−1+ar1=al2+al2+1+… +ar2−1+ar2. If such four integers exist, you will discredit Valerii. Do they exist? An exhibit c is a subarray of a cluster d if c can be acquired from d by erasure of a few (potentially, zero or all) components from the start and a few (conceivably, zero or all) components from the end. Input Each test contains various experiments. The main line contains the number of experiments t (1≤t≤100). Depiction of the experiments…
How does a MAX2SAT reduce to a NAESAT (not all equal SAT), can you give an example for this reduction in detail by steps? (Introduce the reducibility of MAX2SAT to NAESAT)
All businesses want to keep their customers happy. To do that, many companies assign a certain amount of time to each customer to optimize the business. The alternative would be to hire more employees, which would lead to higher costs. This problem requires you to simulate how authorities optimize the number of cashiers at the entrance of a toll bridge to make sure drivers are satisfied. Make the following assumptions: There is one cashier per line. The line works as a queue with no cars cutting the line or leaving it. One car arrives at the entrance every 10 seconds. It takes 90 seconds (1.5 minutes) to process the payment, starting from the moment a cashier is available. Assume there is no pause between cars. Written in java, Your Tasks: Design class CarInLine, with the following specifications: The class has two instance variables: arrivalTime and DepartureTime, stored as integers. Define a constructor that accepts an integer as an argument representing the arrival time, in…
