Highly rated and experienced tutor and researcher.
I am grateful for the many clients who have helped my career flourish at Wyzant and am always happy to work with referrals. However, if you and I have not corresponded before, please let me know how you found me and what your needs are before the first phone conference.
I am a writer, researcher and editor
who has been published in several peer reviewed scientific journals. My research has been presented at prestigious venues such as Yale and Columbia. My focus is on education, language
I am also an experienced educator who has taught and tutored college students all over the world and mentored fellow teachers.
I have a Bachelor's in Political Science
, a Master's in Education and am now working on my Ph.D in speech language and hearing science.
My background in education, including several years in Asia and Europe, has given me insight into the diverse needs of students. I have worked in the classroom, in curriculum development and also in teacher training.
Over the years I have tutored a number of students in statistics
, American History
, Government and Politics, Law
, SAT Writing
and many other subjects. I am grateful for so many wonderful WyzAnt students and their families!

The standard normal distribution is also called the bell curve because of its shape. The idea is that you have the mean (which has a Z value of 0) and then three standard deviations to the right of the mean and three to the left. It looks like this:
If we assume that Nataliya is right and the question is
(4x - 12) / (x2 + 4x - 21)
We can simplify it like so
(2x-3.46)/(x+2x-4.58): This takes the square root of your original equation
First, you want to get all the variables you are trying to solve for on one side
so subtract 4x from both side
That leaves you with
4x+6=26 (because 4x-4x=0 so that term is eliminated)
