7/15 is your answer I am so happy that I could help :)
1)
you have similar triangles(ABC, ADE), so their side length ratios are equal
8/2=4/CE
CE*4=4
CE=1
2)
angle bisector theorem:
CD/DA=BC/BA
CD/DA=10/8
I:AD=10CD/8
we also know AC=AD+CD=6
II:CD=6-AD
insert II in I:
AD=10(6-AD)/8
=5(6-AD)/4
=(30-5AD)/4
4AD=30-5AD
9AD=30
3AD=10
AD=10/3
AB=AC=BC . .......................................................
<span>0.3, 0.1, -0.2, -0.001 are all little to no correlation.
The closer our values get to 1 or -1, the stronger the correlation. Anything below 0.5 is not a strong correlation.</span>
