Braking distance on a wet surface for the 2015 Toyota Camry is normally distributed with a mean of 149 ft. and a standard deviation of 5.28 ft. The braking distance on a wet surface for the Honda Accord is also normally distributed but with a mean of 138 ft. and standard deviation of 6.22 ft. If 25 randomly selected Camrys and 16 randomly selected Accords are selected (independently), what is the probability that the mean braking distance for the Camry is more than 10 ft. longer than the mean braking distance of the Accord

Given:

The given point is (4,12).

To find:

The equation that would NOT contain the point (4,12).

Solution:

We need to check each equation for the point (4,12).

In option A, the given equation is:

Putting , we get

This equation contains the point (4,12).

In option B, the given equation is:

Putting , we get

This equation does not contain the point (4,12).

In option C, the given equation is:

Putting , we get

This equation contains the point (4,12).

In option D, the given equation is:

Putting , we get

This equation contains the point (4,12).

Only the equation in option B does NOT contain the point (4,12). Therefore, the correct option is B.
