The moon orbits the earth at a distance of about 60 earth radii away. However, its gravitational pull is still large enough to cause the ocean tides on the earth. Based on your knowledge of the force of gravity, which of the following could you infer would increase the size of the earth's ocean waves the most? A. Double the mass of the moon B. Move the moon to only 30 radii away from the Earth C. Double the moon's orbit speed D. Double the spin speed of the moon

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.
