Practice Interpreting Data:
2a. 13% of the day is spent watching TV.
2b. 8 hours are spent sleeping. 2c. Studying takes up the least amount of time just 4%. 2d. Going to school takes a quarter of the day. 2e. Sleeping and going to school are two activities that take up 50% of the day. 2f. Watching TV and talking on the phone takes up 25% of the day. |
10a. 9 planets are represented in the graph.
10b. 7 moons are represented in the graph. 10c. The moon that has more mass is lo.10d. Venus has the closest radius to the earth. 10e. 0 moons are larger than pluto because it is a planetoid and its bigger. 10f. lo is closest to the planet jupiter. 10g. Venus is the planet closest to the earth. |
Practice Making Graphs:
Problem 1
A. Make a line graph of the data.
B. The dependent variable is Average thickness of the annual rings(cm) C. The independent variable is Age of trees in years. D. 3.5 is the average thickness of the annual rings of 40 year old trees in Forest A. E. Based on this data, what can you conclude about Forest A and Forest B? |
Problem 2
A. Make a line graph of the data
B. Number of Tadpoles is the dependent variable. C. pH of water is the independent variable. D. The average pH in this experiment is 8. E. The average number of tadpoles per sample is 80. F. The Optimum water pH for tadpole development is 6.5 G. Between numbers 6 and 7 is the greatest change in tadpole number H. Approximately 50 tadpoles I would you expect to find water with a pH reading of 5. |
