About 250 million drivers are registered in the united states. while on a trip with her family, a student counted the number of male drivers and female drivers on the road. she counted 82 male drivers and 118 female drivers. using this sample, predict the number of female drivers out of 250 million, rounded to the nearest million. show all work and justify your answer.

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
