Joel is an amateur bird watcher. during one trip, he measured the amount of time it took to watch 5 birds as 5 1/2 seconds, 3 seconds, 8 1/4 seconds, 6 1/6 seconds, and 2 5/6 seconds. what is the average amount of time joel measured?

What is the quadric regression equation that fits these data

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 %
