rjkz [21]

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

Solve the equation: sin(2x)= sin x

Anna [14]

Answer:

Below

Step-by-step explanation:

sin(2x) = 2 ×cos(x)× sin(x)

● sin(x) = 2 × cos(x) × sin(x)

● 2 × cos(x) = 1

● cos (x) = 1/2

So we can deduce that:

● x = Pi/3 + 2*k*Pi

● or x = -Pi/3 + 2*k*Pi
