We are given the following in he question:
Mean of sample A = 6
Mean of sample B = 12
Formula:


a) original samples have n = 4 scores

b) first sample has n = 3 and the second sample has n = 6

c) first sample has n = 6 and the second sample has n = 3

Answer:
6
Step-by-step explanation:
You started with 18 and you multiply 6×2 and you get 12 able your answer is 6 I believe. sorry if I'm wrong
Answer:
(C)26 units
Step-by-step explanation:
Since point B bisects AC into two equal parts
AB=BC
Since the two right triangles have side BD in common, we can then say that the two triangles are congruent and the length of the hypotenuses (AD and DC) are equal.
If AD=DC
8x-1=6x+9
8x-6x=9+1
2x=10
x=5
Now,
AB=3x-2
=3(5)-2
=13 Units
Since AB=BC
AC=AB+BC
=13+13
AC=26 units
The measure of AC is 26 units.
The answer to the question is b
