Classify the following pairs of events as disjoint or not, and independent or dependent. Choose the most likely scenario in each case. For the purposes of this exercise, assume that weather events separated by more than one month in time are independent. J = {it rained once last week}
K = {it rained once last month}
L = {it did not rain at all in the past twelve months}
M = {it did not rain one day three months ago}

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 %
