Across
- 2. triangle a triangle with one right angle.
- 6. an arrangement of a group of objects in which order is important. The number of permutations of r objects from a group of n objects is denoted nPr
- 7. in a right triangle the cosecant of angle A is the ratio of the length of the hypotenuse to the length of the side opposite A. It is the reciprocal of the sine function
- 9. in a right triangle, the cosine of angle A is the ratio of the length of the side adjacent to angle A to the length of the hypotenuse. It is the reciprocal of the secant function.
- 10. of linear equations a system of equations containing only linear equations
- 12. formula in a coordinate plane the distance from (x1,y1) to (x2,y2)
- 13. if n is a positive integer =, then n is factorial, written n!, is n times (n-1) times (n-2) …. The factorial of 0 is defined to be 1
- 14. the statistical study of the relationship between the variables
Down
- 1. of best fit the line that comes the closest to all of the points in the data set
- 3. the side opposite the right angle in a right angle
- 4. of a right triangle one of the two sides of the right triangle that form the right angle
- 5. binomials of the form a+b and a-b. The terms are the same; the signs before b are opposites
- 8. a measure of the strength and direction of the relationship between two variables or data sets
- 9. a selection of a group of objects in which order is not important. The number of combinations of r objects chosen from a group of n objects is denoted nCr
- 11. coefficient a number r, where -1<r<1, that describes how closely the points in a scatter plot cluster around the least square lines
