A. 27+44 = 71 ft
71/3 = 23 2/3 yards
B. 52 ft = 52/3 = 17 1/3 yards
C. 71 + 52 = 123 ft
23 2/3 + 17 1/3 = 41 yards
D. 8 yards = 24 ft so total feet would be
123 + 24 = 147 ft
41 + 8 = 49 yards
I think its 8, if you count up all the ducks it's 7. But it's talking like it's counting the ducks in front,middle and behind a duck so 7+1=8.
Well, you didn't show the question but i can tell you this: first find the mean of the data set.
1) 1+2+3+4=10 10/4(amount of #)=2.5
then, subtract the mean from each number in the data set.
2) 1-2.5= -1.5; 2-2.5= -0.5; 3-2.5= 0.5; 4-2.5= 1.5
convert all these numbers to positive, then add them together.
3)1.5 + 0.5 + 0.5 +1.5 = 4
divide the total by the amount of # in the data set
4/4=1
the MAD in this case is 1.
Hope i helped!! :)
