A recent survey of 500 people reported that 67% of American adults believe that high gasoline prices are
caused by the greed of oil companies. The margin of error was reported as 3%. What does this margin of error mean?

Select one:

A. It is unlikely that the reported statistics would be 67%, unless the true value was between 64% and 70%

B. No more than 70% of the population believes that high
gasoline prices are caused by the greed of oil companies.

C. Three percent of the people were not surveyed

D. Three percent of the time, the value obtained would be
different from 6796

E. We are confident to a certain confidence level) that the actual parameter is between 64% and 70%.

Ron has 8 caps and 4 of his caps are blue. thes rest of his cap are red. how many of ron's caps are red

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)
