answer:MATLAB is not typically used for developing e-commerce websites with integrated payment gateways and multi-currency support. Instead, web development languages such as HTML, CSS, JavaScript, and server-side languages like PHP or Python are commonly used for this purpose. That being said, MATLAB can be used for data analysis and modeling related to e-commerce websites, such as predicting sales trends or analyzing customer behavior. If you are interested in developing an e-commerce website, you may want to consider using a web development framework such as Ruby on Rails, Django, or Laravel, which have built-in support for payment gateways and multi-currency support. Here is an example of MATLAB code for predicting sales trends using linear regression: ``` % Load sales data salesData = readtable('sales_data.csv'); % Split data into training and testing sets trainingData = salesData(1:500,:); testingData = salesData(501:end,:); % Create linear regression model model = fitlm(trainingData, 'Sales ~ Advertising + Price + Promotion'); % Predict sales for testing data predictedSales = predict(model, testingData); % Calculate mean squared error mse = mean((testingData.Sales - predictedSales).^2); % Display results disp(['Mean squared error: ', num2str(mse)]); ``` This code assumes that you have a CSV file called `sales_data.csv` with columns for sales, advertising, price, and promotion. The code loads the data, splits it into training and testing sets, creates a linear regression model, predicts sales for the testing data, calculates the mean squared error, and displays the result.

answer:1. Imperative sentence with a serious tone: "Please turn off the lights in this room, as we need to conserve energy and reduce our carbon footprint." 2. Interrogative sentence with a polite tone: "Additionally, can you inform us of the estimated time it takes for the lights to fully turn off, and the potential consequences of leaving them on for an extended period?" 3. Exclamatory sentence with an enthusiastic tone: "Energy conservation is incredibly important for the environment! We can all make a difference!"

answer:Here's a Python program that generates a random integer between 1 and 100 using the Mersenne Twister pseudorandom number generator algorithm, and calculates the probability of the generated number being a prime number using the Miller-Rabin primality test algorithm. The program uses multithreading to improve the efficiency of the calculations. ```python import random import time import threading def is_prime(n, k=5): if n < 2: return False for p in [2, 3, 5, 7, 11, 13, 17, 19, 23, 29]: if n % p == 0: return n == p s, d = 0, n - 1 while d % 2 == 0: s, d = s + 1, d // 2 for i in range(k): x = pow(random.randint(2, n - 1), d, n) if x == 1 or x == n - 1: continue for r in range(s - 1): x = pow(x, 2, n) if x == n - 1: break else: return False return True def generate_random_number(): return random.randint(1, 100) def calculate_probability_of_prime(n): start_time = time.time() probability = is_prime(n) elapsed_time = time.time() - start_time return probability, elapsed_time def worker(): while True: n = generate_random_number() probability, elapsed_time = calculate_probability_of_prime(n) print(f"{n}t{probability}t{elapsed_time:.6f}") if __name__ == '__main__': for i in range(10): threading.Thread(target=worker).start() ``` The `is_prime` function implements the Miller-Rabin primality test algorithm. The `generate_random_number` function generates a random integer between 1 and 100 inclusively using the Mersenne Twister pseudorandom number generator algorithm. The `calculate_probability_of_prime` function calculates the probability of the generated number being a prime number using the `is_prime` function, and also measures the elapsed time for the calculations. The `worker` function is the target function for each thread, which generates a random number, calculates its probability of being prime, and prints the result in a table format. The program creates 10 threads, each running the `worker` function. Each thread generates a random number, calculates its probability of being prime, and prints the result in a table format. The multithreading approach improves the efficiency of the calculations by allowing multiple calculations to be performed simultaneously.
