The parent square root function has a starting point at the origin. In standard form that would look like this: 
, where the number inside the radical with the x indicates side to side movement, and the number following either a + or a - indicates up or down movement. Our movement is up or down, since there is no number with the x under the radical. Because that is +2, our parent graph moves up to units from an original starting point of (0, 0) to a new one of (0, 2). Summary: the parent graph moves up 2 units, third choice above
Answer: 47.72 %
Step-by-step explanation:
Given : The scores of students on a statistics course are normally distributed with a mean of and a standard deviation of
.
Let x be the random variable that represents the scores of students on a statistics course .
z-score :
For x= 476
For x= 646
Now, the probability of the students scored between 476 and 646 on the exam will be :-
Hence, the percentage of the students scored between 476 and 646 on the exam = 47.72 %
