Aspinner has three sections. the table shows the results of spinning the arrow on spinner 80 times.

three column table. first column values are section 1 and 28. second column values are section 2 and 36. third column values are section 3 and 16.

what is the experimental probability of the arrow stopping over section 1?

a.1/28

b.7/20

c.7/13

d.4/5

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 %
