In R- Write a function that takes in a string indicating the response variable, and a vector of strings indicating covariate values, and returns a string containing a model formula, such as \verb!"Sale_Price ~ Gr_Liv_Area + Total_Bsmt_SF"!

Write a function in Scala programming language that takes a string parameter and returns whether the string starts with "Sc" or not. Test the function for the sample strings "Scala", "Programming", "Science".

In program problem5.py, write a function named sums that takes 3 arguments: 2 lists of integers nums1 and nums 2, and an integer target; then return a tuple containing indices i and j of the two numbers in nums 1 and nums 2, respectively, where the numbers at that indices add up to target (i.e, nums1 [i] + num2[j] = target). If there is no solution, return "Not found". The function sums must contain exactly only one loop (either a for-loop or a while-loop), otherwise you will get no point. A nested-loop is considered as more than one loop. You can assume that each given input either have exactly one solution or none. Below is the code of the main function in problem5.py, complete the program by writing the function sums. Note that the values of nums 1, nums2 and target are given in the main function which can be changed in the code. This program does not take any input. if name __main__': nums1 = [11, 2, 15, 7, 8] nums2 = [3, 4, 5] target = 9 print(sums(nums 1, nums2, target)) Example…

Instructions There are four clubs in Tesset University South, North, West, and East. A Tesset student can choose to join any number of clubs. Your task is to determine how many students are enrolled in exactly two clubs. Write a function/method named dualClubCounter that will accept a string containing the student number and his desired club. Return a set containing the name of students are enrolled exactly in two clubs. Use SET in your solution Example #1 INPUT: "12300:East,12301:West, 12302:South, 12300:West, 123 Expected Content of Set = [12300] Example #2 INPUT: "12300:East,12301:West, 12302:South, 12300:West,123 Expected Content of Set = [12300, 12301]

rite a function numPairs that accepts two arguments, a target number and a list of numbers.  The function then returns the count of pairs of numbers from the list that sum to the target number. In the first example the answer is 2 because the pairs (0,3) and (1,2) both sum to 3. The pair can be two of the same number, e.g. (2,2) but only if the two 2’s are separate twos in the list.In the last example below, there are three 2’s, so there are three different pairs (2,2) so there are 5 pairs total that sum to 4. Sample usage: >> numPairs( 3, [0,1,2,3] )2

A function that turns an argument to a string (call it “toString(…)”) is a great use of function overloading. In one sentence, why might this be? In one sentence, why should we generally verify the arguments are what we expect when writing a function?
