30 is the answer. You do 10X 3 which is 30- 2 which is 28 and 28 to the nearest 10th is 30
Step-by-step explanation:
Mean=sum of observations/no. of observations
Perpendicular lines have negative reciprocal slopes. So if the slope is -2/5...to find the negative reciprocal, " flip " the slope and change the sign.
So we flip -2/5 and we get 5/-2...and now we change the sign...and we get 5/2. So our perpendicular slope will be 5/2.
Answer:
