Find the mean, median, mode, range, variance, and standard deviation of numbers 7 11 11 15 20 20 28

Hello!

The mean is 16.

The median is 15.

There is no mode. (11 and 20 both occur twice.)

The range is 21.

The standard deviation is 0.

Hope this was helpful. Correct me if i'm wrong. Have a great day!

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
