Step-by-step explanation:
First, we may wonder, what does the term <em>margin of error</em> mean? Put simply, the margin of error is a measure of the degree to which research results do not reflect the views of the total studied population. In other words, it tells readers how much confidence they should have in the results presented.
It has often been suggested that a fundamentally and conceptually effective way that is always under the control of the researcher of making the margin of error smaller is to<em> increase the sample size</em> of the research. This basically involves collecting more sample data which thus leads to a closer estimate of the view of the entire population.
Answer:
4
Step-by-step explanation:
when all the lengths are multiplied by x (length scale factor), the volumes are multiplied by x³ (volume scale factor).
∴ when volume scale factor = 8
the length scale factor = ∛8 = 2
while When all the lengths are multiplied by x (length scale factor), the areas are multiplied by x² (surface area scale factor).
∴ when the length scale factor = 2
the surface area scale factor = 2² = 4

Remainder Theorem says that if there is any Polynomial equation P(x), which is to be divided by (x - a) then remainder can be calculated by substituting value of a in equation P(x).
= P(x) divided by ![(x+2)](https://tex.z-dn.net/?f=%28x%2B2%29)
Step 1: Find a
To find a we will have to convert (x+2) into (x - a) form
i.e. (x+2) = (x - (-2))
therefore, a = -2
Step 2: Substitute value of a in P(x),
By substitution we get,
![2(-2)^{4}+(-2)^{2}-10(-2)-1](https://tex.z-dn.net/?f=2%28-2%29%5E%7B4%7D%2B%28-2%29%5E%7B2%7D-10%28-2%29-1)
= ![2(16) + 4 +20 -1](https://tex.z-dn.net/?f=2%2816%29%20%2B%204%20%2B20%20-1)
= ![32 +4 + 20 - 1](https://tex.z-dn.net/?f=32%20%2B4%20%2B%2020%20-%201)
=
= Remainder
Hence, Remainder is 55.
