Answer:

<h2>The standard error of the mean is 7.56</h2>

Step-by-step explanation:

The standard error of the mean is defined as the ratio of standard deviation to the square root of the sample size of a data. The standard error of the mean is mathematically expressed as shown below;

$X = \frac{\sigma}{\sqrt{n} }$

X is the standard error of the mean

$\sigma$ is the standard deviation

n is the sample size.

Given;

$\sigma = 121\\n = 256$

On substitution into the formula we have;

$X = \frac{121}{\sqrt{256} }$

$X = \frac{121}{16} }\\$

X ≈ 7.56

Find the equation of the line passing through the points (6,3) and (-4,3)<br> Y=

Molodets [167]

${ \qquad\qquad\huge\underline{{\sf Answer}}}$

Equation of line passing through given points :

Let's proceed with two point form ~

$\qquad \sf \dashrightarrow \: y - y1 = \cfrac{y2 - y1}{x2 - x1} (x - x1)$

Assume :

$\qquad \sf \dashrightarrow \: y - 3= \cfrac{3 - 3}{ - 4 - 6} (x - 6)$

$\qquad \sf \dashrightarrow \: y - 3= \cfrac{0}{ - 10} (x - 6)$

$\qquad \sf \dashrightarrow \: y - 3 = 0$

$\qquad \sf \dashrightarrow \: y = 3$

So, the equation of required line is : y = 3 ~
