A skateboarder travels on a horizontal surface with an initial velocity of 4.0 m/s m / s toward the south and a constant acceleration of 2.5 m/s2 m / s 2 toward the east. Let the x x direction be eastward and the y y direction be northward, and let the skateboarder be at the origin at t=0 t = 0 .

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.
