A bag has 7 red marbles 8 blue and 5 purple Rachel draws a marble from the bag without looking. What is the probability that Rachel draws a blue marble

Step-by-step explanation:

7 red

8 blue

5 purple

20 total

8/20 blue

5/20 purple

7/20 red

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.
