Answer:
P(B) = 0.65
Step-by-step explanation:
The appropriate formula is ...
P(A or B) = P(A) +P(B) -P(A and B)
Then P(B) is ...
P(B) = P(A or B) +P(A and B) -P(A)
P(B) = 0.8 +0.15 -0.3
P(B) = 0.65
Answer:
D. 
Step-by-step explanation:
We have been given an image of a scalene triangle. We are asked to find the equation that can be used to find the value of “b".
We know that perimeter of a triangle is sum of three side lengths of the triangle.
Upon adding the measure of side lengths for our given triangle, we will get:

Combining like terms we will get,

Substituting the value of perimeter and 'a' in above equation we will get:



Upon looking at our given choices, we can see that option D is the correct choice.
