Mr. Billings conducted an experiment with bag of marbles. Mr. Billings did not tell his students what color of marbles were in the bag. Mr. Billings had 30 students choose a marble at random from the bag, record its color and then replace it in the bag. The results of the experiment are presented in the table: What is sample space as shown in the table?

A) S = 30 marbles

B) S = 12/30

C) S= {blue, green, red, yellow}

D) Can not be determined since we do not know what colors are in the bag.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

where's the diagram?
