Answer 1

Answer:

1)answer is 1

Q)If P(E) = 0.05 what is the probability of not E?

answer : 1-0.05=0.95

2)Volume of cone =Volume(V) = ⅓ π$r^{2}$h cubic units.

3)let height of tower be h

tan 60=$\sqrt{3}$

h/15=$\sqrt{3}$

h=15$\sqrt{3}$

4)infinite

5)The curved surface area of a hemisphere = 2πr² square units.

6)odd numbers=1,3,5

p(E)=3/6 =1/2

7)radius=d/2 =100/2 =50

8)number of male male candidates= 5

p(E)= 5/8

a tip when you want answers fast :

usually when you give so many questions or big questions, people don't like to answer big ones so , while asking question, increase the number of points so that they will answer to get points

have a nice day:)

2)Volume of cone =Volume(V) = ⅓ πr^2h cubic units.

3)So sorry I don't know 3rd one :(

4)infinite

5)The curved surface area of a hemisphere = 2πr² square units.

6)odd numbers=1,3,5

p(E)=3/6 =1/2

7)radius=d/2 =100/2 =50

8)number of male male candidates= 5

p(E)= 5/8
