Which of the following explains why the Earth orbits the sun rather than the sun orbiting the Earth? A. Earth has much smaller mass, so the gravitational force accelerates the Earth much more than it accelerates the sun.
B. The force of Earths gravity pulling on the sun has a smaller magnitude than the force of the sun pulling on Earth.
C. While the Earth is pulled toward the sun with a gravitational force, the sun is not pulled toward the Earth be a gravitational force.
D. Even though the sun is pulled toward the Earth, the force is opposed by forces from the gravity of the planets.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
