True 2. False 3. group_name3 4. group_name4 Objects: 0. If A and B are 2x2 matrices, then their product is 2x2 1. inverse matrix is the x^-1 key on the calculator 2. recursive formula uses the first term in the formula 3. divisibility of 2 ends in a 0 4. If A and B are 2x2 matrices then A%2bB is 2x2 5. If I multiply a (2x4)(4x3) my result is a 4x4 6. explicit formula is given on the formula sheet 7. squrt(3) is real and rational 8. .33333 is equivalent to 2/3 9. If I multiply a (2x1)(1x2) my result is a 2x2 10. summation notation is using the sigma sign 11. squrt(4) is only real and rational 12. 4.45 is the same as 4 %2b (45/100) 13. AB=BA always 14. prime numbers have only one and itself as multiples 15. squrt(25) is natural, whole, integer, rational, real 16. To add fractions, you just add across 17. A%2b B = B%2bA 18. GCF uses prime factor tree, multiply by what%27s left 19. integers are any positive and negative numbers 20. To multiply fractions, you multiply across 21. A -B = B-A 22. Your grade is a discrete variable 23. 0 is a whole number but it%27s not natural 24. If I multiply a (2x3)(2x3) my result is a 2x3 25. I can find the sum of an infinite series if r%3e1 26. Distance is a continuous variable 27. divisibility of 10 number ending in 0 or 5 28. If I multiply a (2x1)(1x3) then my result is undefined 29. I can find the sum of an infinite series if r%3c1 30. Divisibility of 3 last 3 digits multiple of 3 31. real numbers numbers that terminate |
