I got 30, I’m not sure if it’s correct or not.
Answer:
x=2
Step-by-step explanation:
2In(4x)=2In(8)
determine the defined range
2In(4x)=2In(8) , x is greather than 0
divide both sides by 2
In(4x)=In(8)
set the arguments equal
4x=8
divide both sides by 4
x=2, x is greater than 0
x=2
Answer:
Not independent.
Step-by-step explanation:
Given that P(A)=0.25 , P(B)=0.2 , and P(A and B)=0.04
To check whether A and B are independent.
Two events are independent if
P(A/B) = P(A) or P(B/A) = P(B) or P(AB) = P(A) P(B)
if any one of the above three is true also, the two events would be independent.
Let us find out first one
P(A/B ) = P(AB)/P(B) (as per conditional probability formula)
= 0.04/0.2=0.2
But P(A) = 0.25 and not equals P(A/B)
Hence we can conclude that A and B are not independent
because P(A/B) not equals P(A)
Answer:
I think it's B
Step-by-step explanation:
Answer:
.125 = 1/8
Step-by-step explanation:
4 ^-1 = 1/4 (.25)
2^3= 2x2x2=8
8 / 16 = .5
.5 x .25 = .125 converts to 1/8
