Answer:
A
Step-by-step explanation:
The "mean" is the average score. An average is found by adding all of the values and dividing by the number of values added (find the mean of 2,4,6. 2+4+6=12, 12/3=4, mean=4)
682+601+744+674+701+790+676+638+773=6279, 6279/9=(697 and 2/3) rounded=698. A

Answer:
The focus is:
Step-by-step explanation:
Given
Required
Determine the focus
The focus of a parabola
is:
So, we have:
Cross multiply
Rewrite as:
Rewrite as:
Express 8 as 4 * 2
By comparison with:
So, the focus is:
The slope can be found by subtracting two adjacent y values, e.g., 165-132 = 33
The initial value is the y value at x=0, ie., 132.
So the equation must be: y = 132 + 33x
