D
Step-by-step explanation:
x,y 2,3 just trust me good sir
Answer:
A,C and D
Step-by-step explanation:
A: 3x2=6
3x4X=12X
<em>6+12X</em>
C: 5x1=5
5x2X=10X
5+10X+1+2X
<em>6+12X</em>
D: 7x1=7
7x2X=14X
7+14X-2X-1
6+14X-2X
<em>6+12X</em>
All of the choices (1 , 2 , 3 and 4) are correct
Here is what I got for the first one. MAD=
1/(N)*(|x1-xm|+|x2-xm|+..+|xN-xm|)
=1/5(|85-83|+|83-83|+|87-83|+|90-83|+|70-83|)
=1/5(2+0+4+7+13))
=5.2
And for the second one I got, MAD=
1/(N)*(|x1-xm|+|x2-xm|+..+|xN-xm|)
=1/5(|75-76|+|74-76|+|68-76|+|83-76|+|80-76|)
=1/5(1+2+8+7+4))
=4.4
To find all the different possible combinations, you multiply all the possibilities for each position.
1st - she as 20 different possible buttons
2nd - she would have 19 possible buttons
3rd-she would have 18 possible buttons
20 x 19 x 18=6840 possible ways to choose these buttons.
