Answer:

Center: (0, 0); Vertices: (-√ 7,0),(√ 7,0) Foci: (-√ 5,0),(√ 5,0)

Step-by-step explanation:

Center is at (0,0) because you can see it when graphed. Same with everything else.

(5,9), (5-3)<br> what is the slope?

monitta

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

When you want to find out what the slope is, you have to remember what the formula is first....

$m=\frac{y}{x} =\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

so in this case -3 would be the $y_{2}$ because it's the y in the ordered pair and it's the second one. Then one of the 5's would be $x_{2}$ and 9 would be $y_{1}$ and then the other 5 would be $x_{1}$ .

now if we plug it in

$\frac{-3-9}{5-5} =\frac{-12}{0}$

now we can tell that we can't divide by zero so the slope would be unidentified and that's it.

P(F) = 0.5
P(L) = 0.3
$P(F\cap L)=0.2$
$P(F\cap L')=0.5-0.2=0.3$
$P(F'\cap L)=0.3-0.2=0.1$
$P(F'\cap L')=1-0.3-0.2-0.1=0.4$
