I know this isn't math but what would be the topic sentence? "First of all, being alive and healthy is key to a persons happines

garik1379 [7]

The first sentence starting with, "First of all..." is the topic sentence. The second is not because it is adding detail to the sentence given.

Hope this helps!

$\dfrac{1}{2 \sqrt{7} + 3 \sqrt{3} }$

$= \dfrac{1}{2 \sqrt{7} + 3 \sqrt{3} } \times \dfrac{2 \sqrt{7} - 3 \sqrt{3}}{2 \sqrt{7} - 3 \sqrt{3}}$

$=\dfrac{2 \sqrt{7} - 3 \sqrt{3}}{(2\sqrt{7})^2 - (3\sqrt{3})^2}$

$=\dfrac{2 \sqrt{7} - 3 \sqrt{3}}{28 - 27}$

$=\dfrac{2 \sqrt{7} - 3 \sqrt{3}}{1}$

$=2 \sqrt{7} - 3 \sqrt{3}$

Please helpppp it has to do with P(A U B)

Katyanochek1 [597]

$P(A)=0.5$ , $P(B)=0.6$ , $P(A\cup B)=0.8$

We find the probability of intersection using the inclusion/exclusion principle:

$P(A\cap B)=P(A)+P(B)-P(A\cup B)=0.3$

By definition of conditional probability,

$P(A\mid B)=\dfrac{P(A\cap B)}{P(B)}=\dfrac{0.3}{0.6}=0.5$

For $A$ and $B$ to be independent, we must have

$P(A\cap B)=P(A)\cdot P(B)$

in which case we have $0.3=0.5\cdot0.6$ , which is true, so $A$ and $B$ are indeed independent.

Or, to establish independence another way, in terms of conditional probability, we must have

$P(A\mid B)\cdot P(B)=P(A)\cdot P(B)\implies P(A\mid B)=P(A)$

which is also true.
