Across
  1. 2. A proposition or theorem by contradicting both the subject and predicate or both the hypothesis and the conclusion and interchanging them. for ex.if not A, then not B, if A, then B.
  2. 5. A ratio comparing amount of change in the dependent variable to the amount of change in the independent variable.
  3. 7. inequalities with the same solutions.
  4. 10. an ordered pair that makes both equations true.
  5. 11. the value or values that occur most frequently in a data set.
  6. 13. a line with slope m and y-intercept b can be written as y=mx+b.
  7. 14. a number whose cube is X.
  8. 17. the middle value or average of the two middle values.
  9. 19. statement that compares two expressions.
  10. 20. the positive square root of a number, indictated by a radical sign.
  11. 21. the difference between the greatest and least values in the data set.
Down
  1. 1. an inequality in one variable that can be where a and b are real numbers.
  2. 3. A measure of the steepness of a line
  3. 4. to find all of the variables for which the equation is true.
  4. 6. A measure that describes the center of the data set.
  5. 8. A data value that is far removed from the rest of the data.
  6. 9. ratio that compares a number to 100.
  7. 12. is formed by switching the hypothesis and the conclusion.If p, then q, if q, then p.If two lines don't intersect, they are parallel
  8. 15. the sum of all values in a data set
  9. 16. An increase or decrease given as a percent of the original amount.
  10. 18. containing terms of which increase in one results in a decrease into another. Reversed in position,order,or direction; its reciprocal.
