NORMALIZATION PROBLEM: Normalization is one of the most basic preprocessing techniques in data analytics. This involves centering and scaling process. Centering means subtracting the data from the mean and scaling means dividing with its standard deviation. Mathematically, normalization can be expressed as: X-X 0 In Python, element-wise mean and element-wise standard deviation can be obtained by using .mean() and .std() calls. In this problem, create a random 5 x 5 ndarray and store it to variable X. Normalize X. Save your normalized ndarray as X_normalized.npy

- INSTRUCTIONS: Write a Python script/code to do the given problems. NORMALIZATION PROBLEM: Normalization is one of the most basic preprocessing techniques in data analytics. This involves centering and scaling process. Centering means subtracting the data from the mean and scaling means dividing with its standard deviation. Mathematically, normalization can be expressed as: X - X In Python, element-wise mean and element-wise standard deviation can be obtained by using .mean() and .std() calls. In this problem, create a random 5 x 5 ndarray and store it to variable X. Normalize X.Python application creation The system call inv in the numpy.linalg library can be used to calculate the inverse of a matrix. A basic 2 by 2 matrix's inverse can be calculated using Python code. The identity matrix I is then generated by multiplying the inverse of A by itself for proof.in python while using the libraries Pandarallel seaborn, pandas, and numpy then read in the dataset ‘geyser’ from seaborn Write some function that does a somewhat computationally complex task on a value / row of data. Using python time functions, apply this function on the dataframe and time it. Then apply this same function on the dataframe using pandarallel’s parallel_apply, and time this. Experiment with the timing / different functions Compare the run times
- Hill cipher decryption: I must find the encryption key in order to decrypt a specific message. All i know is that the encryption key is 3x3 matrix and the specific message begins with the phrase "CONFIDENT". I must do this in python. I understand how to decrypt stuff once I have the key matrix. But I am confused as to how to find the key matrix in the first place with the information given.O(nlgn) means that there is function f(n) that is O(nlgn) which is an upper bound for the running time at large n Select one: True FalseWhat will happen if the pseudo code given below executes? func(x): IF x < 50: PRINT X x=x*5 RETURN func(x) /Tester func(2) DOutput values 2,10,50 will be printed Function has a parameter which takes integer As there is no base case error will occur Maximum limit of recursion will be exceeded
