Answer:
We cannot infer a cause and effect relationship because the treatments imposed were not blocked correctly.
Step-by-step explanation:
The treatments given to the groups given in the question where not assigned proper treatments to establish proper randomized block design.
Thus, we can say the conclusion is that we can't truly infer a cause and effect relationship as the blocks were not properly done.
Im pretty sure it is cause multiply 2/3 times 2 is 4/6
Answer:
see below
Step-by-step explanation:
The ratio of terms that are two terms apart (s4 and s6) is the square of the common ratio:
s6/s4 = r^2
r = √(8/18)
r = 2/3 . . . . . matches choices A and C
__
Using the formula for the general term, we now know enough to find the first term:
sn = s1·r^(n-1)
s4 = s1·(2/3)^(4-1)
Using s4 = 18 and multiplying by (2/3)^-3, we get ...
18·(2/3)^-3 = s1 = 18·27/8
s1 = 243/4 . . . . . matches choice A
Length = 4/5 ft
area = 3/10 ft.
Width = 3/10 ÷ 4/5 ft
= 3/10*5/4 ft
= 3/8 ft
Perimeter = 2(L+W)
= 2(4/5+3/8) ft
= 2(32+15)/40 ft
= 47/20 ft
= 2.35 ft
