Answer:
L and M - None of these
L and N - Skew
M and N - Perpendicular
Step-by-step explanation:
A mean is an average of a total. If you add all the pets together and divide by the number of people, you get the mean. So 1 +3 + 2 + 4 + 0 = 10
You have 10 pets in total.
There are 5 people.
Mean = 10 pets / 5 people = 2 pets per person. that's the mean or average that everyone has.
N=25 because 20 divided by 4 is 5 which is 1/5 of n meaning 5x5 is 25
