the residual is the difference between the observed Y and the estimated regression line(Y), while the error term is the difference between the observed Y and the true regression equation (the expected value of Y). Error term is theoretical concept that can never be observed, but the residual is a real-world value that is calculated for each observation every time a regression is run. The reidual can be thought of as an estimate of the error term, and e could have been denoted as ^e.
You can crack a 3-digit combination lock by sequentially trying every possible number. Writing down and keeping track of every number used will help avoid confusion and speed up results.

Well...all the importance. every structural design, every safety factor, every hidrologycal analysis, every mechanical analysis, everything, even the materials used are based on statistics. The results gotten from the analysis are projected to other conditions, and the probability of them to interact together (for example, earthquake, wind and max load. Or having the highest flow and rain)
Why is 21 February observed every year?
every thing around you.
1). Sabbath, observed every Saturday. 2). New Month, observed within the first few days after every new moon.
Every 4 years

Yes, it does. It is observed every year by Muslims.

The solutions will be extremely similar to what you would get for equations in Newtonian physics. At everyday speeds the deviation from Newtonian mechanics is negligible.
5th,may every year
A phenomenon that occurs the same way every time it is observed is known as a constant.
Only one month every year ..
