1. Please explain which rules of calculus lead from step 1 below to steps 2 and 3, and from step 3 to step 5:

Step 1: RSS = sum from i = 1 to n (yi - b0 - b1xi)^2

Step 2: deltaRSS/deltab0 = (- 2) sum from i = 1 to n (yi b0 - b1xi) = 0

Step 3: deltaRSS/deltab1 = (- 2) sum from i = 1 to n (xi(yi - b0 - b1xi)) = 0

Step 4: sum from i = 1 to n (yi) = b0n + b1 sum from i = 1 to n (xi) (normal equation 1)

Step 5: sum from i = 1 to n (xi yi) = b0 sum from i = 1 to n (xi) + b1 sum from i = 1 to n (xi^2) (normal equation 2)

Expert Solution

Hope it helps.

<Vector Calculus> Please show all step by step work and formulas. Thanks A current in a river is pushing a ship in a direction of 25 degrees north of east with a speed of 12 knots (nautical miles per hour). There is a 7 knots (kn) wind pushing the ship in a direction 80 degrees south of east. Find the velocity vector of the ship vector of the ship relative to the water if the ship is moving due east...

STEPS IN THE CAPITAL RATIONING PROCESS Step 1: Identify potential capital investment projects. Step 2: Establish a minimum average rate of return and/or a maximum desired cash payback period to screen the projects. Eliminate any project that fails to meet these standards, unless the project has overriding qualitative benefits. Step 3: Evaluate the remaining projects, using net present value and/or internal rate of return techniques. Step 4: Consider the qualitative benefits of each project. Step 5: Rank the projects, based on the results of Steps...
