Across
- 4. means 'triangle measurement.' used to calculate lengths of sides and measures of angles in triangles
- 6. the sum of values in a set of data divided by the number of values in the set of data
- 7. the length of time for which interest is calculated before being accumulated
- 9. the difference between the greatest and the least values in a set of data
- 10. an extreme value in a set of data. the value is "far away" from the others
- 13. three values that divide a set of data into four intervals with equal numbers of data
- 14. the side that forms one of the arms of the angle being considered in a right triangle, but is not the the hypotenuse
- 15. a² =b² + c² -2bc cos A
- 16. a group of individuals or items that are representative of the population from which they are taken
Down
- 1. data that are distinct and can be counted, ex the number of students who like rice
- 2. the longest side of a right triangle. the side across the right angle
- 3. quadratic relation y=a(x-h)² + k
- 5. a binomial of the form x² -r² . the factors of a difference of squares are (x-r)(x+r)
- 8. the middle value when data is ordered from least to greatest
- 11. a set of outcomes with the same results
- 12. the x-intercepts of a quadratic relation. the value of x when y = 0
