Answer:Simple random sample

Step-by-step explanation:

A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen. A simple random sample is meant to be an unbiased representation of a group.

NOTE:

No easier method exists to extract a research sample from a larger population than simple random sampling. Selecting subjects completely at random from the larger population also yields a sample that is representative of the group being studied.

Can somebody explain this in a basic way and help me graph it??!!
7nadin3 [17]

Hello!

To graph this, you will want to create two points based off of the equation. You plug an x-value into the equation, and you put the y-value outcome with it as an ordered pair. You do this twice, giving you two points to connect.

For example, let's plug in an x-value 1, giving us (1,y)

y= 1-3 (We remove the absolute value)

y=-2 (Subtract)

This gives us one point, (1,-2)

Let's try using -2 as another point.

y= 2-3 (Remove absolute value)

y= -1 (Subtract)

This gives us the point (-2,-1)

To graph, you would draw a straight line through the points (1,-2) and (-2,-1). Note you could do this with any x-value and you would get the same line.

I hope this helps!

kolezko [41]

Answer:

\dfrac{-x}{3}should be added to the given equation.

Step-by-step explanation:

Let a is added to the given equation.

According to the given condition,

\dfrac{5x}{6}-4+a=\dfrac{x}{2}-4\\\\a=\dfrac{x}{2}-4+4-\dfrac{5x}{6}\\\\a=\dfrac{x}{2}-\dfrac{5x}{6}\\\\a=\dfrac{3x-5x}{6}\\\\a=\dfrac{-2x}{6}\\\\a=\dfrac{-x}{3}

So, \dfrac{-x}{3}should be added to the given equation.
