8. Alexander was studying the effect of playing rock music on plant growth. One of the plants was exposed to rock music for 24 hours a day for a
period of 6 weeks. Data on the growth of the plant was collected at
the end of each week and plotted in a graph. Based on the data,
which would be the MOST reasonable measurement at the end of an
8-week period?
A. 2 decimeters B. 6 decimeters
C. 8 decimeters D. 16 decimeters

C. 8 decimeters

Explanation:

As seen on the graph, the height of the plant is located on the y-axis while the period of growth or time in weeks is located on the x-axis. If you observe closely, the plant has an average growth of 1 decimeter per week.

week 1 = 1 decimeter

week 2 = 2 decimeters

week 3 = 3 decimeters

week 4 = 4 decimeters

week 5 = 5 decimeters

week 6 = 6 decimeters

week 7 = 7 decimeters

So, this means that at the end of the 8-week period, the plant's height is at 8 decimeters.

answer; polycythemia is the correct answer;
