A power company located in southern Alabama wants to predict the peak power load (i. e., the maximum amount of power that must be generated each day to meet demand) as a function of the daily high temperature (X). A random sample of summer days is chosen, and the peak power load and the high temperature are recorded each day. The file P10_40.xlsx contains these observations. A. Create a scatterplot for these data. Comment on the observed relationship between Y and X. B. Estimate an appropriate regression equation to predict the peak power load for this power company. Interpret the estimated regression coefficients. C. Analyze the estimated equation’s residuals. Do they suggest that the regression equation is adequate? If not, return to part b and revise your equation. Continue to revise the equation until the results are satisfactory. D. Use your final equation to predict the peak power load on a summer day with a high temperature of 100 degrees.

You will be given two character arrays of the same size, one will contain a number of ships. ships will move around the character array based on which way they are facing and the route they are on. routes are given in the other array. the route consists of '-' and '|' for straight paths, '\' and '/' for curves, and '+' for intersections. there are ships on these routes. ships always face a direction, '^' for up, '> ' for right, 'v' for down, and '< ' for left. any time the ships hit a '\' or a '/' it will turn as you would expect a ship to turn (e. g. a '^' that moves into a '/' will turn right). at an intersection, ships will always continue straight through. all ships move at the same speed, ships take turns moving and all ships move during one 'tick'. the one in the most top left goes first, followed by those to its right, then the ones in the next row. it iterates along the rows and then down the columns. each ship moves one space on its turn moving along the route. your function needs to return the position of the first collision between two ships and the number of ticks before the crash occurred.
