Answer:

IQR = 3

Step-by-step explanation:

The interquartile range (IQR) is the difference between the upper quartile Q₃ and the lower quartile Q₁

Q₃ is the value at the right side of the box , that is Q₃ = 62.5

Q₁ is the value at the left side of the box. that is Q₁ = 59.5

Then

IQR = Q₃ - Q₁ = 62.5 - 59.5 = 3

Hello there! The axis of symmetry is the vertical line where the parabola can be divided and there are two equal halves. The vertex is on that line. The point where this occurs is all in the positive range, so that eliminates B, C, and D. (0.5, 4.25) is the vertex and 0.5 is the axis of symmetry. The answer is A. Your answer is correct.
