It is given that a,b,c are positive values. 1) show that (a+b+c)((1/a)+(1/b)+(1/c)) >= 9
2) If a+b+c=1 , show that (2-a),(2-b),(2-c) are positive
3) Using above results show that [(a/(2-a)) + (b/(2-b)) + (c/(2-c)) ] >= 3/5

Question: points A (-1,-2),B(7,2) and C (k, 4), where K is a constant, are the vertices of triangle ABC. Angle ABC is a right angle. Calculate the value of K?
1.) A graduate program at a university has an admission eligibility policy that requires applicants to be in the top 20% of admissions test scores. If the test scores have a mean score of 1485 with a standard deviation of 240, what is the test score that determines the cut-off for the top 20%? I know that this problem has to do with Z-score but I’m not sure how to go about calculating it!
Given an array A of numbers of length n (indexed starting at 0), verify that the following pseu-docode program returns the index of the smallest element in the array. What is the LOOP invariant Hint: You should have more than one component to your loop invariant, and both minVal and minLoc should appear somewhere in the invariants. def findMin(A): n = length(A) minVal = A minLoc = 0 for (i = 1, i
