Sock drawer contains 5 different colors of socks. It has 20 white, 10 black, 10 gray, 6 red, and 4 purple. If you
ach into the drawer and choose a sock randomly, what is the probability you will get a black sock?

1:5

Step-by-step explanation:

First add all of the socks together.

20+10+10+6+4=50 socks altogether

If 10 of those are black socks, then we can write the expression to 10/50.

We can then simplify that to 1/5 and turn it into a ratio.

The final answer is 1:5.

Hope this helped :)

- "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."
