To solve a problem using the equation for Kepler’s third law, Enrico must convert the average distance of Mars from the Sun from meters into astronomical units. How should he make the conversion?

multiply the average distance by 1.5 × 1011
multiply 1.5 × 1011 by the average distance
divide the average distance by 1.5 × 1011
divide 1.5 × 1011 by the average distance

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
