Question:I can't find several answers to this math crossword anywhere! Please help! Most answers correct wins! ACROSS 7. A set: where the + or x of any of its elements results in an element of that set; where commutative, associative, and distributive properties hold true for + or x ; which has additive and multiplicative inverses; which has identity elements for + and x.

The point at which a function's tangent has a slope zero is either a minimum or ____ point. (7 letters) 45. {1,1, root2} is an example of a Pythagorean ____. (7 letters) -- I thought it was triple, but that is 6 letters. Would it be triplet? 58. If segment AB is divided at point M such that AM/MB=AB/AM, then AM/MB is called the ____ section, ratio or mean. (6 letters) 64. Space higher than 3-dimensional.

Answers:ACROSS 7) group 37) it could be be COBOL or ALGOL 41) extreme (or extrema) 45) triplet 58) golden 69) magic DOWN 5) inscribed 23) conjecture 26) point 34) Mobius. are you sure it is seven letters? his name contains only 6 letters...unless they are doing the weird alternate spelling "Moebius" (which, technically, is incorrect)

Answers:1. Control 2. Procedure 3. Conclusion 4. Scientific Method 5. Independent 6. Hypothesis 7. Graphs (assuming) 8. Experiment 9. Problem 10. Model 11. Dependent 12. Collect 13. Data 14. Observations I'm sure you could have found all the answers on a worksheet you've done or in your textbook. I'm going to write down some notes I want you to copy so you have this information so science will make more sense to you (if you're not getting it.) IT WILL BE EXTREMELY HELPFUL FOR FUTURE REFERENCE!!! Define Problem - An approach to problem solving, can be used by anyone from observation or research (ALWAYS a question.) Ex: How much fertilizer makes bean grow the tallest? Form Hypothesis - Educated guess, if... then... because, testable - can collect data (#'s, observations, inference) Ex: IF I test 0, 1 tsp, 2 tsp and 3 tsp of fertilizer on beans, THEN beans will grow tallest with 2 tsp. BECAUSE... Experiment - organized way to test a hypothesis Control: standard for comparison Ex: 0 tsp of fertilizer Constant: stays the same Ex: amount of heat, light, soil Dependent variable: data/results you collect Ex: height of plants (# of flowers, etc) Independent variable: what is tested/what investigator changes Ex: amount of fertilizer (Easy way to remember dependent and independent so you don't get mixed up is D = data.. for dependent and I = investigator for independent) Field Study - Replaces exp. in situtations where many observations are used to collect data Ex: animal behavior, dinosaurs Conclusion - Accept or reject your hypothesis Model (Physics) = an idea or math expression that is similar to what scientists are trying to explain Ex: atom model: solar system Theory = well supported, well tested explanation, which unifies a broad range of observations Ex: dinosaurs extinct from a meteor Law - Explains an action or expected outcome Ex: gravity, math, physic laws Repeat (more hypothesis??) - Publish results, allow others to check your results (LOTS OF DATA NO EXCEPTIONS!) By suggestion improvements or changes, others can learn from your results. I really hope you copy this down it will be so useful to you. Hope this was helpful & good luck!!! :)
