7. Suppose it is 5 minutes past Midnight on January 25 th, 2010. What value corresponds to these statements? DATE 10025 TIME 300 (5 mins * 60 sec / min) DATE$ “20100125” TIME$ “00:05:00”

8. What are the largest and smallest possible values of: INT(RND*100) INT(SQR(RND*100)) INT(MAX(RND*100, RND*10)) INT(MIN(RND*100, RND*10))

9. What are the largest and smallest possible values of: Smallest is zero for all. Largest is listed below INT(RND*100) 99 INT(SQR(RND*100)) 9 (highest perfect square < 100) INT(MAX(RND*100, RND*10)) 99 INT(MIN(RND*100, RND*10)) 9

10. What would be the problem with this program if it was used every day to determine the winner of a lottery? PRINT "Your Lucky Six Numbers Are:“ PRINT 1+INT(RND*100), 1+INT(RND*100) END

11. What would be the problem with this program if it was used every day to determine the winner of a lottery? PRINT "Your Lucky Six Numbers Are:“ PRINT 1+INT(RND*100), 1+INT(RND*100) END Missing RANDOMIZE, so the winning numbers would be the same every day
