Yes, they are independent. First of all, we know that P(A) = 1/4, P(B) = 2/5, and P(A and B) = 1/10. To know if two events are independent, the following questions must be true: P(A)*P(B) = P(A and B). So since (1/4)*(2/5) = 2/20 which equals 1/10, these events are independent
Answer:
9

Answer:
x=16 x=2
Step-by-step explanation:
x^2-18x+81=49
x^2-18x+81-49=0
x^2-18x+32=0
(x-16)(x-2)=0
x-16=0
+16+16
x=16
x-2=0
+2 +2
x=2
