Answer:
Yes they are.
They are congruent because they have two equal angles and one equal side
C(t)= -0.3t^2 + 7.2t - 3.2
12c = 40
0.75^2 = 0.5625.....sq rt 0.5625 = 0.75
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:
Subtract 9 from each side of the equation
Step-by-step explanation:
m+9=-2
-9 -9
m=-11
