You add everything with the same power of x together, for exmple you have 2x^3 and the 3x^3 the x^3 is the same in both so you just add it to get 5x^3, then you do the same thing for everything collect the like terms, those who have x^2 is only -4x^2 that's the only thing left, so you write it down, and proceed to x

From a population of 200,000,000 elements, the standard deviation is known to be 14. A sample of 49 elements is selected. It is

Talja [164]

Answer:

The standard error of the mean = 2

Step-by-step explanation:

Given that:

The standard deviation σ = 14

The sample size n = 49

The sample mean $\overline x$ = 56

The formula for calculating the standard error can be expressed as:

$S.E = \dfrac{\sigma}{\sqrt{n}}$

$S.E = \dfrac{14}{\sqrt{49}}$

$S.E = \dfrac{14}{7}$

S.E = 2

Therefore, the standard error of the mean = 2
