Answer:
Step-by-step explanation:
<u>Combination for the school government requires:</u>
- 5 out of 8 seniors = 8! / 3!5! = 6*7*8/2*3 = 7*8 = 56
- 4 out of 9 juniors = 9! / 4!5! = 6*7*8*9/2*3*4= 7*2*9 = 126
- 3 out of 12 sophomores = 12! / 3!9! = 10*11*12/2*3 = 10*11*2 = 220
- 2 out of 7 fishermen = 7! / 2!5! = 6*7/2 = 21
<u>So number of total ways is:</u>
Answer:
f=4
Step-by-step explanation:
-11f=7(1-2f)+5
-11 f=7-14f+5
14f-11f=12
3f=12
f=4
The ans is:
cos 20 =x/80
x=75.2
