Step-by-step explanation:
step 1. 3(sqr(27) - 16) sqr is the square root
step 2. 3(3sqr3 -16)
step 3. 9sqr3 - 48.
Example:
To make ‘u’ the subject of the formula in
V = u + at
*subtract ‘at’ to both sides*
V -at = u + at - at
Result:
V - at = u
So the answer would be
u = V - at
Answer:
A and B are not independent events because P(A|B)≠P(A)
is the correct answer.
Step-by-step explanation:
If A and B are independent then we must have
P(AB) = P(A) P(B) and also
P(A/B) = P(A)
We are given that
A and B are two events.
Let P(A)=0.5 , P(B)=0.25 , and P(A and B)=0.15 .
P(A/B) = P(AB)/P(B) = 0.15/0.5 = 0.3
i.e. P(A/B) is not equal P(A)
Similarly P(B/A) = P(AB)/P(A) = 0.15/0.25 = 0.6 not equal to P(B)
Hence A and B are not independent.
53 is not a perfect square and whereby not using a calculator, 53 is between the perfect squares of 49 and 64. Hence the answer should be between 7 and 8. since 53 is closer to 49, then the answer should be close to 7. use a calculator to verify
