Use the standard normal distribution to find p(-2.25 < z < 1.25)

Here we have to find the probability . Now express the probability in terms of standard normal cumulative distribution function. That is .

Now you can look up the probability from the standard normal tables. Its value is

Step-by-step explanation:

The distance initially is how far she is from the lair.

After she starts running, the distance decreases according to her velocity.

So the equation relating the distance d between Nala and the entrance of the lair is a function of t, the time in seconds since Nala began running can be modeled by an equation in the following format:

In which is the initial distance and v is the speed that she is running, in meters per second.

The entrance is 180 meters away.

This means that

Speed of 9.2 meters per second.

This means that

So
