IV. Two integers x and y are said to be of the same parity if x and y are both even or are both odd. The integers x and y are of opposite parity if one of x and y is even and the other is odd. For example, 5 and 13 have the same parity while 8 and 11 are of opposite parity. a. Prove that for all integers x and y, if 41(x² − y²) then x and y have the same parity. - b. State and prove the converse of "part a" of this problem.

Question 4 Beachcomber Ltd in a local car dealership that sells used and new vehicles. The manager of the company wants to know how different variables affect the sales of his vehicles. A random sample of yearly data was taken with the view to testing the model: SALES-a+BAGE+YMIL+SENG Where SALES= amount that a vehicle is sold for($000's), AGE = age of the vehicle, MIL= the total mileage of the vehicle at the point of sale and ENG = the size of the engine. The sample of data was processed using MINITAB and the following is an extract of the output obtained: The regression equation is ***** Predictor Coef StDev t-ratio p-value Constant 1.7586 0.2525 6.9648 0.0000 AGE 0.2124 0.3175 0.5042 -2.0991 7.7664 MIL -0.7527 0.3586 大* ENG 4.8124 0.6196 0.0000 Analysis of Variance Source I p DF SS MS Regression 413.1291 138.7097 ** * 0.00 Error 50 457.7607 2.2888 Total 53
