The table shows the number of practice problems completed in 30 minutes in three samples of 10 randomly
selected math students.
Number of practice problema completed in 30 minutes
Sample 1 12 13 11 10 11 13 12 13 9 13 Mean = 11.7
Sample 2 13 18 17 14 15 14 18 14 15 16 Mean = 15.4
Sample 3 18 14 16 15 16 14 17 16 15 14 Mean = 15.5
Which statement is most accurate based on the data?
O A. A prediction based on the data is not completely reliable, because
the mean of sample 1 is noticeably lower than the means of the
other two samples
OB. A prediction based on the data is not completely reliable, because
the means of samples 2 and 3 are too close together.
OC. A prediction based on the data is reliable, because the means of
samples 2 and 3 are very close together
O D. A prediction based on the data is reliable, because there are no
noticeable differences among the samples.

The table shows the relationship between the number of cups of cereal and the number of cups of raisins in a cereal bar recipe: number of cups of cereal number of cups of raisins 8 2 12 3 16 4 molly plotted an equivalent ratio as shown on the grid below: a graph is shown. the title of the graph is cereal bars. the horizontal axis label is cereal in cups. the x-axis values are 0, 20, 40, 60, 80,100. the vertical axis label is raisins in cups. the y-axis values are 0, 10, 20, 30, 40, 50. a point is plotted on the ordered pair 40,20. which of these explains why the point molly plotted is incorrect? (a) if the number of cups of cereal is 40, then the number of cups of raisins will be10. (b)if the number of cups of raisins is 40, then the number of cups of cereal will be10. (c) if the number of cups of cereal is 40, then the number of cups of raisins will be 80. (d) if the number of cups of raisins is 40, then the number of cups of cereal will be 80.
