Manuel and Sandy were partners. Sandy held the accelerometer in her hands while Manuel watched the water line. Throughout Sandys walk,
the water line remained level. What does that tell the students about
Sandy's motion?
Sandy's velocity changed when she slowed down or
sped up.
A)
Sandy's speed might have changed but her direction
B) did not.
Sandy must not have been moving if the water line
remained level
Sandy's velocity is constant: her speed and direction
did not change.
D)

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.
