How is the mode of a data set defined?
a. it is the middle value of the set.
b. it is the most common value in the set.
c. it is the average of the different values in the set.
d. it is the difference between the highest and lowest values of the set.

B.It is the most common value in the set.

Explanation:

The mode of a data set is the value that is repeated most times, that is, the one with the highest absolute frequency. If there are two values ​​of the variable that have the highest absolute frequency, there would be two modes. If no value is repeated, there is no mode.

33: i think it’s b

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
