A social studies teacher gives her students a pretest and a final test for a unit. She creates a scatter plot with each student's pretest score on the x-axis and each student's final test score on the y-axis. The equation of the trend line for the scatter plot is y 0.9x 12 Based on the equation of the trend line, what final test score would be predicted for a student who had a pretest score of 70?

How do you create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1?

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
