In an inductive generalization, in order to achieve an error margin of plus or minus 3 percentage points at a confidence level o
ANTONII [103]
Let n =  required random sample size.

Assume that the population standard deviation is known as σ.
Let m =  sample mean.
At the 95% confidence level, the expected range is
(m - k(σ/√n), m + k(σ/√n))
where k = 1.96.

Therefore the error margin is 1.96(σ/√n).
Because the error margin is specified as 3% or 0.03, therefore
(1.96σ)/√n = 0.03
√n = (1.96σ)/0.03
n = 128.05σ²

This means that the sample size is about 128 times the population variance.

Answer:
Smallest sample size = 128.05σ², where σ = population standard deviation.

How to find the perimeter of a square one side is 10x other side is 6x+8?
Yanka [14]
To find the perimeter of the square, you add all four sides together:
10x + 10x + (6x + 8) + (6x + 8)
20x + 12x + 16 = P
32x + 16 = P

you have to find x to get the actual perimeter. Since the shape is a square, all 4 sides are equal, so you can set 10x and (6x + 8) as equal to each other.
10x = 6x + 8
4x = 8
x = 2

Now you just plug in x and finish the rest of the problem, and you have the answer:
32(2) + 16 = P
64 + 16 = P
P = 80

How to add fractions 1/3+3/4
BARSIC [14]
You change 1/3 and 3/4 so that they have the same denominator.
The GCF is 12 in this case.

1/3 x 4 = 4/12
3/4 x 3 = 9/12

4/12 + 9/12 = 13/12 or 1 1/12 (One and one twelfth) 


Hope this helped !!
