circle
scatter plot
What is a valid conclusion that can be determined from the data shown on this graph?
The cooler the temperature, the louder the crickets chirp.
The crickets cannot chirp at temperatures lower than 10 degrees C.
The warmer the temperature, the more often crickets chirp.
The temperature and the chirping of crickets are not related.
A student set up an experiment to test the effect of the number of seedlings planted in one pot on the rate of growth. All conditions in the experiment were the same, except for the number of plants in each pot. The results are shown in the graph below.
According to the graph, which statement is true concerning the growth of the plants?
The plants in the pot with only 5 plants grew to be an average of 40 cm tall in 30 days
The plants in the pot with only 10 plants grew to be an average of 30 cm tall in 20 days.
The plants in the pot with 15 plants grew an average of 20 cm taller after a period of 10 days.
The plants in the pot with 20 plants grew an average of 20 cm taller after a period of 40 days.
The graph below shows atmospheric carbon dioxide levels since the year 1880.Which of the following conclusions can be drawn from this graph
Atmospheric carbon dioxide levels are responsible for global temperature change.
Atmospheric carbon dioxide levels have been rising at about the same rate for the past century.
Atmospheric carbon dioxide levels have remained the same over the past century.
Atmospheric carbon dioxide levels have been rising at an increasingly higher rate as the past century has progressed.
