What is the simplified form of the following expression?

Amanda [17]

You have sqrt(8), sqrt(18), and sqrt(2).
You need to simplify the radicals.
sqrt(2) is already simplified.
For both sqrt(8) and sqrt(18), you need to factor out the greatest perfect square.

8 = 4 * 2
You can take the square root of 4 and put it outside the root.

18 = 9 * 2
You can take the square root of 9 and put it outside the root.

$5 \sqrt{8} - \sqrt{18} -2 \sqrt{2} =$

$= 5 \sqrt{4 \times 2} - \sqrt{9 \times 2} -2 \sqrt{2}$

$= 5 \times 2\sqrt{2} - 3 \sqrt{2} -2 \sqrt{2}$

$= 10\sqrt{2} - 3 \sqrt{2} -2 \sqrt{2}$

$= 5\sqrt{2}$

Consider two events such that P(A)=3/4, P(B)=2/5 and P(AnB)=1/3. Are the events A and B independent?

posledela

If P(A) times P(B) is equal to P(A n B), then that shows the events are independent. Otherwise, they are dependent. When I write "A n B", I mean "A intersect B". The intersect symbol looks similar to the lowercase letter n.

P(A)*P(B) = (3/4)*(2/5) = (3*2)/(4*5) = 6/20 = 3/10

Since that result is not the same as P(A n B) = 1/3, this means that the events are not independent. They are dependent events. The answer is choice D
