For example.,
Lets say
y
=
x
+
1
is equation 1.
So here, when
x
=
4
,
y
=
5
.
Also,
y
=
1.25
x
, is equation 2
Here also, when
x
=
4
,
y
= 5 ,
But these equations give different results when
y
= 18
For equation 1,
18
=
x
+
1

So,
x
=
17
For equation 2,
18
=
1.25
x
18
1.25
=
x
So,
x
=

3. A fence on a hill uses vertical posts L and M to hold parallel rails N and P. <4 and <14 are alternate exterior angles.
Alenkinab [10]

Given information:

A fence on a hill uses vertical posts L and M to hold parallel rails N and P

The diagram is attached below

Here lines N  and P are parallel lines

Transversal line for parallel lines N  and P is line L

Calculation:

angle 1  and angle 16 are consecutive exterior angles

If parallel lines are cut by a transversal then consecutive exterior angles are supplementary.

<em><1 +< 16 = 180</em>

<em>115+ < 16 = 180</em>

<em>< 16 = 180 - 15</em>

<em>< 16 = 65</em>

<em />

<em>So measurement of angle 16 = 65 degrees.</em>

Suppose you want to decrease your margin of error by a factor of 3. by what factor, do you need to increase your sample size? in
elena55 [62]
The sample size, n required to produce a margin of error, M, in a probability proportion distribution is given by:

n= \frac{p(1-p)z_{\alpha/2}^2}{M^2}

The above formular shows that the sample size is inversely proportional to the Margin of error.

Then we have:

n= \frac{k}{M^2}

where k is some constant.

Now suppose we decrease M by a factor of 3,

\left(i.e.\  \frac{M_1}{M_2} =3\right)

n_1= \frac{k}{M_1^2}  \\  \\ n_2= \frac{k}{M_2^2}  \\  \\  \frac{n_2}{n_1} = \frac{k}{M_2^2} / \frac{k}{M_1^2} = \frac{k}{M_2^2} \times \frac{M_1^2}{k} = \frac{M_1^2}{M^2_2} =\left( \frac{M_1}{M_2} \right)^2=3^2=9 \\  \\ n_2=9n_1

Therefore, if we decrease the Margin of error by a factor of 3, we need to increase the sample size by a factor of 9.
