Answer: MAD= 3
Step-by-step explanation:
Find the mean of the data set
31+24+32+28+29+36/6= 30
subtract EACH data by the mean, find the absolute value of the answer
31-30= 1 (absolute value)
24-30= 6 (absolute value)
32-30= 2 (absolute value)
28-30= 2 (absolute value)
29-30= 1 (absolute value)
36-30= 6 (absolute value)
Now find the mean of the values
1+6+2+2+1+6/6=3
MAD=3
Answer: Hello this is my first time answering!
DA= 4.5
CB=4.5
XY=9
If YZ=8 then CD=4
Perimeter of trapezoid ABCD=19
Perimeter of trapezoid WXYZ=38
Step-by-step explanation:
I am almost positive the scale is 0.5/1 this means that for DA it would be 4.5. Of course, if DA was 4.5 then so would CB. Everything is half of the second trapezoid.
Thanks!
