A set of cards contains cards numbered 1-10. Mrs. Jacobs class is conducting an experiment in which a card Is drawn from the pile, the number is recorded, and then the card is returned to the set. The class will conduct 800 trials. Based on the theoretical probability which is the best prediction for the number of times a 7 will be drawn from the pile?

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 %
