Question 3. Calculate the area, with the appropriate number of significant figures, of a rectangular room that is 14.10 m wide by 15.0 m long.
A. 212 m
B. 211.5 m
C. 29.1 m
D. 29.10 m
Question 4. The Graph above (number 4) shows Jack's mass over a five month period.
Based on the trend in the data, what do you predict will happen to Jack's mass the subsequent month?
A. Jack's mass will increase
B. Jack's mass will decrease
C. It is impossible to predict because there is no trend in Jack's Mass
D. The next month's data will be anomalous.
Question 5. A scientist collected the data shown in the graph above (aka the pic for question 5) How is the graph useful to the scientist.
A. The graph shows the scientist that the data has a upward trend.
B. The graph shows the scientist that the data point at 2.5 seconds in anomalous.
C. The graph shows the scientist that the data creates a linear graph.
D. The graph shows the scientist that there does not appear to be a trend inthe data so the time and mass are probably not related
1. Accuracy means how close to a specific value the darts are. (how close to bulleyes) High accuracy means the darts are close to bull eyes)
Precision means how close each of the values are to each other. (The dart are close to one another)
2. Non-zero digits are always significant. Any zeros between two significant digits are significant. A final zero or trailing zeros in the decimal portion ONLY are significant.
3. Area of a rectangle is width x length. The answer should be in the fewest sf the problem had. The fewest would be 15.0
4. What is the behavior of the graph? It will follow in the same pattern in the subsequent (next) month.
5.Again what is the behavior of the graph? Do you see a pattern in the graph at every point?
