0 < a < 180/2, is just another way of saying 0° < a < 90°, which is another way of saying angle "a" is in the I Quadrant, where cosine and sine or x,y are both positive.
Apparently, we use "Permutation" when order doesn't matter. In that way, only possible outcomes can be calculated.
P (n, r) = n! ( (n - r)!
Unlike, We use "Combination" when order does matter. Combination gives us all possible values.
C (n, r) = n! / (n - r)! r!
Hope this helps!
Answer:-3
Step-by-step explanation:
know
a+b=1
a-b=2
by combine the equatio you will get 2a+b-b=3
the b cancal each other out left 2a=3 and 3/2 = 1.5 for a
so if 1.5=a then apply 1.5 into a+b=1 and a-b=2 you will receive -.5 for b and 1.5/-.5 will equal to -3
Answer:
this year their was 16 more players so if you have 16 as one of your answers you can go ahead and put that.
Step-by-step explanation:
The answer to #1 is 0.
In order to find the answer to this one (or any of these problems, simply follow the order of operations. In the case of #1, we first want to stick the 0 in for a and then continue.
Since these two numbers cancel, you will get the answer as 0. For the rest of these, follow the basic steps provided by your teacher in PEMDAS.
