Odd numbers on a dice: 1,3,5= 3 numbers
All numbers on dice: 1,2,3,4,5,6= 6 numbers
P=3/6=1/2=50%
Answer:
-(√5)/3
Step-by-step explanation:
The tangent being negative means the sine and cosine have opposite signs. Using the identity ...
cos(o) = ±√(1 -sin(o)^2)
we find ...
cos(o) = -√(1 -(2/3)^2) = -√(5/9)
cos(o) = -(√5)/3
30:2...this is the ratio in decimal form.
The result of this ratio is 15.
Remember it can also be written as a fraction too--> 30/2
You could subsitute g(x) for x in f(x) and if you get x as a result, then that is indeed the inverse
ex
if
f(x)=x-2
the inverse which is g(x) is
g(x)=x+2 because if you did
f(g(x)) then you would get
f(g(x))=(2+x)-2=2-2+x=x
