Find the standard deviation of the data set 10, 2, 38, 23, 38, 23, and 21. Round to two decimal places.

c. (3,2,6) is the answer.

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
