Answer:
0.5
Step-by-step explanation:
First find the mean of the data
3+4+4+5 = 16
16/4 = 4
Find the distance of each data to the mean
4-3 = 1
5-4= 1
4-4 = 0
4-4 = 0
Now find the mean of those
1+1+0+0 = 2
2/4
MAD = 0.5

Answer:
r<4
Step-by-step explanation:
-3(r-4)>0 step 1: distribute the -3
-3r+12>0 explain: -3 times r =-3r, -3 times -4 = 12
next, isolate the -3r by putting 12 on the other side
-3r+12>0 subtract 12 from both sides
-3r>-12 now, divide both sides by -3 (you have to flip the > because you are dividing by a negative) -12 divided by -3 is 4
so you should end up with r<4
Perpendicular lines have slopes that are negative reciprocals to each other, that is, if one slope is a/b, the other is -b/a
in this case, the given slope is 1/3, so the other line's slope is -3/1, which is -3
from the graph we see that the y intercept of line b is -4, so the equation of line b is: y=-3x-4
