Select the correct answer from each drop-down menu. Tony writes an equation to represent the distance he walks in meters, d, in relation to the number of minutes he walks, m.
d= 108m
Mark has created a table to record the numnber of minutes It took him to walk different distances In meters.
Distance
(minutes) (meters)
Time

Assuming that Tony and Mark both walk at a constant rate, the unit rate for Tony is vmeters per minute and the unit rate for Mark
is meters per minute.
On a graph, the line representing Tonys distance covered with respect to time would be
walking speed is
v Mark's line. So, Tony's
v Marks.

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
