The fact that the first chosen student was a girl is already decided, so there is no need to find the probability of that happening. There are a total of 13+10, or 23 students. A girl was already selected, so that leaves 22 students. The chance that a boy is chosen is 10/22, or 5/11.
its is the same as multiplying normally .
For example 1-2-3-4-5-6-7-8- 2 times 2
you just take the starting number (2) and times it by the other number (2) and youll get 4
Answer:
The length of the hypotenuse is equal to 2 units
Step-by-step explanation:
we know that
If the right triangle is formed inside the unit circle (inscribed triangle)
then
the hypotenuse of the right triangle must be equal to the diameter of the unit circle
we have
r=1 unit
D=2*(1)=2 units
therefore
The length of the hypotenuse is equal to 2 units
50-x^2=0
Move the x^2 to the other side
x^2=50
Now take the square root of both sides
x=+_(50)^1/2 (^1/2 means square root)(+_ is plus or minus. Sorry XD)
Now simplify the square root
X=+_5(2)^1/2
Voila. The answer is C
