a. one way to measure the spread of data is to calculate the range (maximum minus
minimum). what range of cell sizes did each sugar grow? why is the range often not a
useful measure of spread?

It is 6% because if you subtract 69-58=6 so 6% is the answer to your question.

(x) - (y) = (1 + 4i)

(3 + 6i) - (2 + 2i) = (1 + 4i)

The answer to this question is & 17.50

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
