Suppose that $g(x)=f^{-1}(x)$. If $g(-15)=0$, $g(0)=3$, $g(3)=9$ and $g(9)=20$, what is $f(f(9))$?

never [62]

Answer:

0

Step-by-step explanation:

$\text{If } g(x)=f^{-1}(x);$ and:$\\g(-15)=0,$ g(0)=3, g(3)=9, g(9)=20$

We are to determine the value of $f(f(9)).$

Now:

$g(0)=f^{-1}(0)=3\\g(3)=f^{-1}(3)=9$

From:

$g(3)=f^{-1}(3)=9\\f(9)=3$

From:

$g(0)=f^{-1}(0)=3\\f(3)=0$

Therefore:

$f(f(9))=f(3)=0$

The advertising department of a nationally circulated magazine wishes to estimate the mean age of its subscribers within 0.5 yea

Answer: Option 'd' is correct.

Step-by-step explanation:

Since we have given that

Margin of error = 0.5 years

Standard deviation = 5

At 90% confidence, z = 1.645

We need to find the minimum size of the sample they must take.

So,

$n=(\dfrac{z\sigma}{E})^2\\\\n=(\dfrac{1.645\times 5}{0.5})^2\\\\n=270.6\\\\n\approx 271$

Hence, Option 'd' is correct.
