A. well, the slow way is to get a few kids with long attention spans, and get them to try every single combination. they probably need to check off each combination of numbers as they try it, or do the numbers in numerical order. === I suspect the manufacturer could reset it for you.

A. How many numbers are there starting from 100 to 999? exactly 900 numbers. 1. there are four kings in a standard deck. draw a card. Probability that it is a king is 4/52 = 1/13. Replace it in to the deck, and draw again. another 1/13 as the probability of king. so the probability of drawing 2 kings is 1/13 *1/13 = 1/169. 2. 4/52 * 3/51. This time you are not replacing, so for second draw, there are 51 cards in total, and 3 kings (you have already taken into account the probability of getting a king on first draw). simplify to get 1/ 221.

A. With five digits to chose from and no repetitions, there are five possibilities for the first digit, four for the second, and three for the third, so there are 5 x 4 x 3 = 60 ways in total, but if you assume you can't have 0 as the first digit of a 3 digit number, this cuts out one option for the first digit leaving 4 x 4 x 3 = 48 ways in total

Asked by Andy C - Fri Jan 30 01:50:43 2009 - - 3 Answers - 0 Comments

A. Buy a house and max out your 401K. Being single can save you a lot of tax money because you have a smaller standard deduction than a couple. I don't know this years amount but it should be about 5,500 so if you pay property taxes of 4K and interest on a mortgage of 12K you have 10K extra deduction and then your charity and state income or sales tax and other things might be deductible. If you are under 50 you can put in about 16K into a 401K, those of us over 50 can put in 22K this year. So if you are in a 25% bracket and get an extra 14K more than the standard deduction and put 16K into a 401K you reduce your taxable income 30K saving 7,500 in taxes.

Asked by hARMaNOoo - Mon Mar 2 11:06:47 2009 - - 6 Answers - 0 Comments

A. Since the numbers are in a form xyx, There are nine possible digits for x (1-9) and ten for y (0-9). So off the bat, there are only 90 numbers in this set. 101x + 10y = 11z For any given x, only one value of y at most is going to produce a multiple of 11. That's because whichever value it is, the next one up will be y+11, and y only goes from 0 to 9. At x=1, the value of y has to be 2, for the number 121. At x=2, y=4, for 242. x=3, y=6: 363 x=4, y=8: 484 As you can see there's a pattern where y=2x. If you add or subtract 11 to y you can still have a multiple of 11. At x=5, y=10, and since y=10 is not an acceptable value, there is no multiple of 11 where x=5. At x=6, y=12. y=12 is not valid but you can subtract 11 to get it back into… [cont.]

A. To have a random sample, everyone has to have the same chance of being selected. Picking every 3rd student is not a random sample. Every student should be assigned a number but not in alphabetical order (all last names starting with A 1-50). A random digit table is a published table of numbers that is statistically viable for choosing random numbers no matter how chosen from the table: by row, column, diagonal or irregularly.
