The margin of error is obtained as the ratio of the standard deviation and the square root of the sample size. It is a measure of the amount of difference that is expected to exist between the actual population value and the value obtained from the sample.

<em>Margin of Error = ±0.01</em>

<u>Margin of Error can be calculated using the relation</u> :

Margin of Error = σ/√n

Margin of Error = 0.228 ÷ √500 = 0.010

Therefore. the margin of error can be interpreted to mean that the value of the mean obtained from the sample is expected to differ from the mean of the population weight by ±0.01

Nataly [62]

Step-by-step explanation:

Given : A triangle with side lengths $a = x^2-1, b = 2x, \text{ and } c = x^2 + 1$

To find : Prove that when x > 1, it is a right triangle. Use the Pythagorean theorem and the given side lengths to create an equation. Use the equation to show that this triangle follows the rule describing right triangles. Explain your steps ?

Solution :

For right triangle the Pythagorean theorem is to be satisfied.

i.e. $c^2=a^2+b^2$
