Shape a is congruent to shape because a 180° rotation about the origin and then a translation unit(s) right maps shape a onto it.

shape b is congruent to shape because a 90° clockwise rotation about the origin and then a translation unit(s) left maps shape b onto it.

What is the name used to describe a graph where for some value of x, there exists 2 or more different values of y?

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable

Ineed in figuring out this problem.
