- 2. an arraignment of a group of objects in which order is important the numbers of permutations of r objects from a group of n objects is denoted
- 8. in a right triangle the cosecant of angle a is the ratio of the length of the hypotenuse to the length of the hypotenuse to the length of the side opposite a it is the reciprocal of the sine function
- 9. of a right triangle one of the two sides of the right triangle that form the right angle
- 11. a selection of 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 .factorial for any polynomial p(x) x-a is a factor of p(x) if only if p(a)=0
- 12. a measure of the strength and direction of the two relationship between two variables or data set
- 13. coefficient-a number r where - 1 less then or equal to r less the nor equal to 1 that describes how closely the points in a scatter plot cluster around the least squares line
- 14. of best fit-the line that comes closest to all of the points in a data set
- 15. binomials of the form a + b and a - b the terms are the same the signs before b are opposites
