Answer: The y-value of the vertex is
Step-by-step explanation: we know that
The equation of a vertical parabola into vertex form is equal to
where
(h,k) is the vertex of the parabola
In this problem we have
-----> this a vertical parabola open upward
Convert to vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
The vertex is the point
The y-value of the vertex is
5t = 25+2r
t = (25+2r)/5 or
t = 5 + (2/5)r

Answer:
Option C is correct.
Step-by-step explanation:
The given data would be most appropriately displayed by a box-and-whisker plot.
a box-and-whisker plot will represent it by representing in form of rectangle with second and third quartile
And in box and whisker plot
The vertical line will represent the median.
Therefore, option C is correct.
