Kylie read 12 books. Dylan only read 6 books and it says Kylie read double. Double means 2 so we do 6 times 2 and we get 12.

For a normal distribution, the z value for an x value that is to the right of the mean is always:

Dmitry_Shevchenko [17]

In a normal distribution, the z value for an x value that is to the right of the mean will always be positive while on the other hand if the z value for an x value that is to the left of the mean it will always be negative. It is because left side is always negative and right side is always positive.

The zero of F -1(x) in F(x) = x + 3 is -3 0 3

Effectus [21]

Answer:

The only zero of $F^{-1}(x)$ is $3$ .

Step-by-step explanation:

The function $F^{-1}$ is the inverse of function $F$ .

For a given $x$ and a given $y$ , $F^{-1}(y) = x$ if and only if $F(x) = y$ .

Let $y$ be a zero of $F^{-1}(y)$ . That is, $F^{-1}(y) = 0$ .

By the reasoning above, since $x = 0$ and this particular $y$ satisfy $F^{-1}(y) = x$ , it must be true that $F(x) = y$ for the same $x = 0\!$ and $y\!$ .

Since $x = 0$ and $F(x) = x + 3$ , $F(0) = 3$ . Therefore, $y = F(0) = 3$ since $y = F(x)$ .

Thus, the zero of $F^{-1}(y)$ would be $y = 3$ .
