Click cell C9 and insert a VLOOKUP function that looks up the code in cell B9, compares it to the codes and types of art in the range B2:C6, and returns the type of art. Copy the function in cell C9 to the range C9:C54. Hide column B that contains the codes.

I want to read the numbers from random_number.txt and then display the number and display total of the number and the number of random number read from the file and the average of this number

Answer in R code please

how do I enter the years row? The language is python

i want copy of this code

n this assignment, we will learn a few fundamentals of Data Science. You will read some data values and display some basic statistics of the data set. Your program should:   Prompt the user to enter an integer number. Validate the user input to make sure it is an integer. If not, ask the user to enter a valid integer only. You may use the str.isdigit(dataValue) function to check whether the user is entering only digits where dataValue is the user input, and the expression returns True if the entered characters were numbers. Add your integer into a list. Ask the user whether they want to add more data. When the user finishes entering data values, display the count, minimum, maximum, range, and average of your data set. To get the range of the data values, you should subtract the minimum value from its maximum. You can calculate count and average using the appropriate built-in functions.

In [ ]: Exercise 1b Write code to calculate and print the quantities from the data sheet. For the momenta pli and p2i, the code is given. For the other quantities, uncomment the respective code lines and add your own code. You must use the given variable names; do not change their case (e.g. from Kli to kli). For full credit: • Use "f-strings" to print your calculated values. • Make sure each quantity is printed with its correct unit. Follow the example for pli. Verify that your code produces sensible results. pli m1*vli p2i = m2*v2i print (f'Momentum of m1 before collision: print (f'Momentum of m2 before collision: #pi #mtot = # pf #p_ratio= #print() #print () #print() #print () = = # Kli = # K2i = #print() # print () #Ki = # Kf = # K ratio = #print () #print() #print () # Momentum of m1 before collision #Momentum of m2 before collision #YOUR CODE HERE raise NotImplementedError() {pli:eP} kg•m/s') {p2i: eP} kg•m/s') # Total momentum before collision # Combined mass #Total momentum…
