Answer:
The equations are really hard, so if you can find a slope interpreter or something that might be helpful.
I find it easier to just count the up and across.

Answer:
4x= 40
Step-by-step explanation:
40/4 = 10
Answer:
0.74 to 6.06
Step-by-step explanation:
The groups are independnet,
SE(xh bar-xa bar)=sqrt [sh^2/nh+sa^2/na]=sqrt [10.1^2/80+10.3^2/80]=1.61
At df=157, the t critical is 1.65
90%c.i=(xh bar-xa bar)+-tcritical SE(xh bar-xa bar)
=(25.2-21.8)+-1.65*1.61
=0.74 to 6.06
Both, depends on the place in which you live
C. 8^4x
64^2x = 4096x
8^4x= 4096x
