Yes, it is reasonable, because the ME is 7.1% and 48% falls within the range of 53.8% to 7.1%.
Calculating the ME:

The sample proportion was 53.8%. This gives us
53.8% +/- 7.1%
Answer:
<h2>
length = 6 cm</h2><h2>
width = 6 cm</h2><h2>
</h2>
Step-by-step explanation:
area of square A = s²
where A = 36
find: sides of squares
solution:
A = s²
just plugin values into the formula
36 = s²
s = √36
s = 6 cm
therefore, the length = 6 cm
width = 6 cm
By using the general formula for a geometric sequence, we will find that the correct option is c: 86
<h3>
Working with geometric sequences:</h3>
The general formula for the nth term in a geometric sequence is:

Where r is the common ratio of the geometric sequence here we know that:
- a₁ = 2
- a₇ = 128
- r is negative.
Replacing the first two in the general formula we get:

Where we took the negative solution for the root. Now that we know the common ratio we can find the other terms:

The sum gives:
2 - 4 + 8 - 16 + 32 - 64 + 128 = 86
So the correct option is c.
