Supposing 30 days in the month of May (which is not always same in every year),we have,
S= Sample Space
n(S)=total days in a year=365 days
n(E)=no of favourable events
= no of days in the month of May=30 days
Then the probability is of favourable events is,
P(E)=n(E)/n(S)=30/365=6/73
Now,the probability that the birthday is not in May is,
P'(E) =1-6/73=67/73 ANS!!!

What is the inverse of f(x)=4x

Allisa [31]

The sum can be rewritten as y=4x, where y=f(x).
Now, we can rewrite the equation a x=y/4
Therefore, inv(f(x))=x/4

Answer:

$x = 1$ or $x = 2$

Step-by-step explanation:

Given:

$f(x) = 2x \hspace{5mm} \& \hspace{5mm} g(x) = 2^x$

We are to find the values of $x$ such that these two functions are equal.

Substitute $x = 1$ .

We get $f(x) = 2(1) = 2 \hspace{5mm} \& \hspace{5mm} g(x) = 2^{(1)} = 2$

Hence for $x = 1$ we have the functions to be equal.

Now for $x = 2$

$f(2) = 2(2) = 4 \hspace{5mm} \& \hspace{5mm} g(2) = 2^{(2)} = 4$

We see the functions are once again equal.
