Step-by-step explanation:
4×p=3/5
cross multiply
20p=3
p=3/20
p=0.15
There are 10 pairs of shoes. 8 shoes are select.
<span>P = (2/20) (2/19) (2/18) (2/17) (2/16) (2/15) (2/14) (2/13) </span>
<span>P = 2^8 / (20P8) </span>
<span>But, any 8 differents shoes can be chosen from 10 pairs. </span>
<span>so there are 10C8 = 45 ways to do so </span>
<span>P = 45 * 2^8 / (20C8) </span>
<span>But, since order does not matter, there are 8! way you can select the 8 different shoes </span>
<span>P = 8! * 45 * 2^8 / (20C8) </span>
<span>P = 384/4199 or about 9.145%</span>
Answer:
angle 8= 120 degrees
angle 7= 60 degress
Step-by-step explanation:
So since it's a line, they will equal 180. So since angle 7 is half of 8 we need to a pair of numbers that add to 180. So you can find out that 120/2 is 60. Then 60+120=180
