Answer:
P(F/E) = 0.5
Step-by-step explanation:
We have the following information:
P(E∩F)=0.1
P(E)=0.2
Additionally, the probability P(A/B) of event A given Event B is calculated as:
P(A/B) = P(A∩B)/P(B)
Now, we want the probability P(F/E), so it is calculated as:
P(F/E) = P(E∩F)/P(E)
Finally, replacing the values we get:
P(F/E) = 0.1 / 0.2
P(F/E) = 0.5
Answer:
x = 14
Step-by-step explanation:
Tan 25 =
Where opposite = x, Adjacent = 30 m
=> 0.466 x 30 = x
=> x = 14
Hello,
The nonagon, polygon with 9 sides, can be divided in 9 triangles which area is
a*c/2
a is the apothem et c the side
Center's angle is 360°/9=40°
as a/14=cos 20°, and (c/2)/14=sin 20°
a*c/2=14*14*sin 20°*cos 20°=14*7*sin40°=98*sin 40°=62,993185...
Area of the nonagon is 9*98*sin 40°=882*sin 40°=566,93867... (in²)
25 because 29 and 34 are in the middle so on the other side the middle number will be 25
