1)  Normal distribution A distribution that takes on the shape of                                                                                               a bell curve.

2) Standard Normal distributionA normal distribution with a mean                                                                                                                                                                                            0  and a standard deviation of 1.

3) deviation  difference between any value and the mean of

                                               the  set.

4) frequency distribution organizes data into categories called

                                                     classes.

5) range difference between the smallest term in the data and      

                          the  largest term in the data set.

6) standard deviation square root of variance.

7) Variance square of the standard deviation.

8) z-score deviation of a value x from the mean of the sample

                                    divided by the standard deviation.

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
