Domain of f = R .............
Answer:A
Step-by-step explanation:
just took it
The more observations you make the closer and closer the experimental probability will approach the theoretical probability. In this case the theoretical probability is:
P(HH)=(1/2)(1/2)=1/4
So in 105 trials one would expect to get two heads:
105(1/4)=26.25 times.
Answer:
728 m^2
Step-by-step explanation:
There are 5 faces of the square pyramid.
You have to calculate area of each face and add them to find surface area.
Bottom face is a square, so
area = 14^2 = 196 m^2
All the other faces are triangle with same area, so
4 × triangle area
4 × ((1/2)×14×19)
4 × 133
532 m^2
Now add those areas,
(196 + 532) m^2
728 m^2
Many (x,y) pairs will fit this equation
Lets let x = 12 then:-
24 = 6y - 24
6y = 48 so y = 48/6 = 8
so one ordered pair is ( 12, 8)
