Marnie conducted an experiment using a bag of 12 marbles containing an equal number of blue, red, and green marbles. she randomly chose one marble, noted the color, and returned the marble to the bag. marnie did this for a total of 20 trials. the table below shows the results.

what was the experimental probability of choosing a blue marble from a bag?

Step-by-step explanation:

Given : The number of times blue marble drawn from the bag =7

The total number of trials = 20

Then , the experimental probability of choosing a blue marble from a bag is given by :-

Hence, the experimental probability of choosing a blue marble from a bag =

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.
