An object is suspended in a wind tunnel and the force measured for various levels of wind velocity: v (m/s) 10 20 30 40 50 60 70 80 F (N) 25 70 380 550 610 1220 830 1450 Write programs that use Least-Squares regression to fit this data with (a) a straight line and (b) a power equation based on log transformations

Write a method named addall that could be placed inside the hashintset class. this method accepts another hashintset as a parameter and adds all elements from that set into the current set, if they are not already present. for example, if a set s1 contains [1, 2, 3] and another set s2 contains [1, 7, 3, 9], the call of s1.addall(s2); would change s1 to store [1, 2, 3, 7, 9] in some order. you are allowed to call methods on your set and/or the other set. do not modify the set passed in. this method should run in o(n) time where n is the number of elements in the parameter set passed in.

Which statistical function in a spreadsheet you to see how far each number varies, on average, from the average value of the list?

Write a program that inserts the digits of an integer into an array in originalorderfollowed by reverse order. first, promptthe user to enter a positive integer(> 0). determine the number of digits of the integer. create a dynamically allocated integer arrayof a size twice the number of digits.now insert the digits in original order which will occupy half of the array. then, insert the digits in reverse order.finally, output thedigits in thearray.use at least two functions to organize your program.
