Answer:
15
Step-by-step explanation:
There can be any whole number of boys from 0 to 14. That's 15 different possibilities.
The answer is 0.3. To find this answer, <span>1/2 / 3/5 = <span>56</span> ≅ 0.8333333</span>
Answer:
The choices were typed wrong, but we can find the inverse of each option.
For function
the inverse is the same function
, because an inverse of a function is where their composition gives the independent variable as unique result.
If we do that with each function, we have:
; where
and
, we have

So they are inverse.
For
its inverse would be
, because

For
, its inverse is
, because

For
, its inverse is
, because

There you have all inverses. Basically, if their composition results in
, that means they are inverse.
