Answer:
C=2πr=2·π·4≈25.13274
Step-by-step explanation:
La raíz de la cuadra de 81 es 9
Answer:
The correct option is C
Step-by-step explanation:
From the question we are told that
The number of independent variables is
The number of observation is
Since n is are independent variables then their degree of freedom is 3
The denominator(i.e z) degrees of freedom is evaluated as
So for the numerator (n) the degree of freedom is Df(n) = 3
So for the denominator(i.e z) the degree of freedom is Df(z) = 43
Answer:
c
Step-by-step explanation:
Answer: B
and
How to solve:
check if the composite functions of f(x) and g(x) are equal to x (this means they are inverses)
f[g(x)] = x
g[f(x)] = x
Step-by-step explanation:
Checking A.
This does not equal x, so we know these are not inverses
Checking B.
since both f(g(x)) = x and g(f(x)) = x, we can determine that they are inverses of each other.
