The mean is the average.
Let A = mean
A = (18 + 14 + 9 + 6 + 3)/5
A = 50/5
A = 10
Ellie's mean time is 10 seconds.

Step-by-step explanation:
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
In this case we have the following equation of the line:

Where:

By definition, if two lines are parallel then their slopes are equal. Thus, a parallel line will have an equation of the form:

Substitute the given point
to find "b":

Finally, the equation of the requested line is:

Answer:

AB is similar to YZ
AC is similar to YX
CB is similar to XZ
you put the triangles next to each other. since they are the same shape. same kind of triangle. one is just bigger than the other.
