Which set of data would most likely show no correlation when graphed on a scatterplot? A. number of pets and number of siblings

B. number of sunny days and umbrella sales

C. the age of a tree and the height of the tree

D. time spent studying and grades made in class

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.

true
