<span>−13b=9
divide both sides by -13
</span><span>−13b/-13 =9/-13
simplify
b = -9/13</span>
a. Use the inclusion/exclusion principle.

b. By definition of conditional probability,

Answer:
8.6
Step-by-step explanation:
To find the distance between two points we use the formula posted below
All we need to do is figure out what the points are on the graph and plug them into the formula... we end up with
the square root of (5-(-2)^2+(2-(-3)^2 and get the answer of 8.602325267
then we round to the nearest tenth and get 8.6
You only need two separate ordered pairs for the slope formula
Since 800 is greater than 0.8 your statement would be 800>0.8
