Suppose P(A)=0.9, P(B)=0.4 and P(B|A)=0.2. What is P(A|B)?
Leokris [45]
The answer is 0.45

------------------------------------

Work Shown:

P(B|A) = P(B and A)/P(A)
0.2 = P(B and A)/0.9
0.2*0.9 = P(B and A)
0.18 = P(B and A)
P(B and A) = 0.18
P(A and B) = 0.18

P(A|B) = P(A and B)/P(B)
P(A|B) = 0.18/0.4
P(A|B) = 0.45

Please help me fast!<br><br> Find the surface area of this cone. Show your work.
k0ka [10]

Answer:

The answer is 628 meters.

Step-by-step explanation:

The area for surface of a cone is pi times the radius (radius plus the square root of the height squared plus the radius squared).

Lol, i know this is really confusing, just look up surface area of a cone formula.

Height squared = 15 * 15 = 225

Radius squared = 8 * 8 = 64

225 + 64 = 289

The square root of 289 is 17

17 + 8 = 25

3.14 * 8 = 25.12

25.12 * 25 = 628 meters.
