Answer:
P(A)=0.55
P(A and B)=P(A∩B)=0.1265
P(A or B)=P(A∪B)=0.7635
P(A|B)=0.3721
Step-by-step explanation:
P(A')=0.45
P(A)=1-0.45=0.55
P(B∩A)=?
P(B|A)=0.23
P(B|A)=(P(A∩B))/P(A)
0.23=(P(A∩B))/0.55
P(A∩B)=0.23×0.55=0.1265
P(A∪B)=P(A)+P(B)-P(A∩B)
=0.55+0.34-0.1265
=0.7635
P(A|B)=[P(A∩B)]/P(B)=0.1265/0.34 ≈0.3721

Answer:
34/13
Step-by-step explanation:
The length-to-width ratio here is:
8.5 / 3.25
which can be reduced by dividing numerator and denominator both by 0.25:
8.5/0.25
--------------- = 34/13
3.25/0.25
Answer:
GE=10
FJ=5
Step-by-step explanation:
We know that in a traingle

a=HE=6
b=FE=8
Once we enter it into the equation, we find that we get
36+64=100
The square root of 100=10
GE=HF so HE=10.
Half of HE(10) is FJ(5)
Hope this help :)
