The number of hours of TV watched each week by 8 seventh grade students is shown below.
11, 7, 9, 3, 3, 8, 10, 5

a. What is the mean number of hours of TV watching?

b. Mean absolute deviation =

c. Explain the meaning of the mean absolute deviation as it relates to the number of hours of TV watched.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

to rewrite a literal equation you may need to divide by a number, or by a variable.
