Suppose we want to create a variable in the sashelp.pricedata dataset. Use a DATA step to create a copy of the sashelp.pricedata dataset and create a new variable that is the sum of the price1, price2, ..., price 17 variables. Note that when using a SAS function, you can specify all columns between two columns (including start and end) using the word of and a dash.

- You are contracted to complete the data system for Citywide Taxi Company. Now, the information for each taxi is expanded to include: taxi id (such as CTC0001), the driver’s name, the maker of the Car (such as Ford), the model of the car (such as Escape), the Color of the Car (such as Black), the license number (such as HXT 4578), the number of passages the car served in the entire shift (integer type, this field will be left empty for this project). Your C++ program will (with array of class object): Define a class for the car with all members of variable mentioned above as private; Write all necessary class member functions to access those member variables (write or read); Read up to 50 records of data from the keyboard (provide a method to end the input before reaching 50 records) Save all records inputted from step 3 to a disk file called CTC.dat.you are required to read input file containing data of countries or region, to compute and display the data in decreasing order, and some statistics in an output file. Structure of input file: The first two lines of input files contains the region information, date of taken data, and heading of the records. Each line of the rest in the input file contains country name, confirmed and death total cases. COVID_19_data class: used to store records from input file. You should provide generic methods to compute average of confirmed cases, to sort list in descending order using selection sortii , and any additional method(s) to solve the problem. Tester Class: your main method should class two methods to read the data and to display the result as shown below. Your class should be user friendly and control any unchecked errorsUse natural split to split the bonus_txt file, then use natural merge to merge the two resulting files back together. What is the value at index 100?

- The “Boston” data set is a built-in dataset in the “MASS” library of R. The “Boston” data set containsinformation about the housing values in suburbs of Boston city. First, load the “Boston” data set intoyour R workspace. In Rstudio, you can click on the “Packages” tab and then on the checkbox next toMASS. Without Rstudio, type the following command in R console: data(Boston,package=”MASS”)To know more information about this dataset, type the following command in R console: ?BostonThen, answer the following questions based on the dataset, using R/Rstudio:a. How many rows and columns in this data set? b. How many of the suburbs in this dataset bound the Charles River? (Hint: Variable chas is adummy variable; chas=1 means tract bounds river, 0 otherwise) You can obtain a list of suburbsbound the Charles River with the command: subset(Boston,chas==1) You can obtain a count of the suburbs bound the Charles River by sum(Boston$chas==1) c. What is the probability that you randomly select a…When you create a case in EnCase you add your information either by a template or enter it individually for each case. Where is this header information contained? It is stored in the header in the first evidence file since it does not have to be written to again It is stored in each data block before the CRC for the next file It is stored in the last section of the evidence file right before the MD5 hash It is stored in the header in each of the subsequent evidence files added to the evidence fileThe rw-r--r-- file corresponds to which of the following umask values?
