To find the volume of a cylinder it's

πr² x height.

So π x 10² x 10 would be the equation.

I would do it but I don't have a scientific calculator on me.

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.

I know it has to be a negative...........

Answer:

$m=-3$

Step-by-step explanation:

Choose 2 points on the graph. (-2,8) (3,-7)
Apply slope formula.

$m=\frac{rise}{run} =\frac{y2-y1}{x2-x1} \\\\\frac{-7-(8)}{3-(-2)} = \frac{-15}{3} =-3\\\\m=-3$

I hope I choose the right cordinates...
