A committee of 4 people is chosen from 7 women and 7 men. How many different committees are possible that consist of 2 women and 2 men?

441

Step-by-step explanation:

2 men from 7 will be the members of committee that makes 7*6/2=21 outputs

2 women from 7 will be the members of committee that makes 7*6/2=21 outputs as well.

Total number of outputs is 21*21=441

- "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."
