Answer:
sin = opposite / hypotenuse
cos = adjacent/hypotenuse
sin U = 4/5
cos U = 3/5
sin T = 3/5
cos T= 4/5
4*1=4
4*2=8
4*3=12
4*4=16
4*5=20
4*6=24
4*7=28
4*8=32
4*9=36
4*10=40
4*11=44
4*12=48
You want to start with L which is 3.2 multiply this by the width 138.8 you get= 444.16 then you multiply that by 9.6 you get = 4263.94 I could be wrong but I Just multiplied it.
Answer:
a) 0.1600
b) 0.3654
Step-by-step explanation:
a) The samples are independents, so:
P(O1∩O2)=P(O1).P(O2)=0.40*0.40=0.1600
b) P(A1∩A2)+P(B1∩B2)+P(AB1∩AB2)+P(O1∩O2)=
P(A1).P(A2)+P(B1).P(B2)+P(AB1).P(AB2)+P(O1).P(O2)=
0.43^2+0.14^2+0.03^2+0.4^2=0.3654
