<h2>The area of a triangle is =54 square units</h2><h2>The perpendicular distance from B to AC is = 
</h2>
Step-by-step explanation:
Given a triangle ABC with vertices A(2,1),B(12,2) and C(12,8)
The area of a triangle is=
=
= = 54 square units
The length of AC =
=
= units
Let the perpendicular distance from B to AC be = x
According To Problem
⇔ units
Therefore the perpendicular distance from B to AC is =
The segments AE, EC, AD and DB are in proportion.
Therefore we have the equation:
AE = 4ft, AD = 8ft and BD = 2ft. Substitute:
<em>multiply both sides by 2</em>
Answer:
0.4
Step-by-step explanation:
The table with correct formatting is attached in the image below.
We have to find P(Y | B). This is a conditional probability i.e. probability of Y given B.
The formula of conditional probability for two event A and B is:
So, for the given case, the formula would be:
P(Y ∩ B) indicates the probability of Y and B occurring together. Y and B occur together 34 times out of total of 324, so:
P(B) indicates the probability of occurrence of B. B occurs 85 times in a total of 324. So,
Using these values in the formula of conditional probability, we get:
Thus, the value of P(Y|B) is 0.4
