Answer:
The center of Walden’s data, 3, is less than the center of Drake’s data set, 6.
Step-by-step explanation:
Walden’s data set doesn’t have any outliers. Drake’s data has an outlier with the value 9, which is at the higher end of the distribution.
sample answer
x=8
(2x + 1)² = x² + (2x - 1)² = x² + (2x - 1)(2x - 1)
(2x + 1)(2x + 1) = x² + 4x²-2x-2x+1
4x²+2x+2x+1 = 5x²-4x+1
4x²+4x+1 = 5x²-4x+1
0= 5x²-4x²-4x-4x+1-1
0= x²-8x
x²-8x=0
x²=8x
<CAB and <DAE are vertical angles
<EAB and <CAD are vertical angles
this is because they are formed by the prolongation of the sides of the other angles and are opposite to them on the other side of the vertex.
use a2+b2=c2 so
11(squared)+b(squared)=13(squared)
=121+b2=169
-121. -121
b2= 48
square root 48
Side B= 6.928
and then just round 6.928
hope this helped
