It is 2x and 4y, so you need to use pythagorean theorem. 2 squared is 4, and 4 squared is 16. Add them, and you get 20. The problem is that that won't square to a whole number, so the closest I can get it is the square root of 20, or 2 root 4.
To find the mean of something, add all the numbers then divide by the number of numbers there are.
40,000 + 50,000 + 40,000 + 60,000 + 90,000 = 280,000
Then divide:
280,000/5 = 56,000
The mean of the annual salaries at the company is 56,000
