Nonamiya [84]

Answer:

The population is the set of all the elements. And the sample is a subset of the population.

Step-by-step explanation:

The population is the set of all the elements. And the sample is a subset of the population.

The sample is used to make conclusions regarding the population.

A poll is conducted from the target population to determine the general opinions of the individuals of that population.

The basic method of polling is to select a few thousand individuals from the population and ask their opinions on a certain subject.

The poll will result usually in two values, the proportion of individual in favor and the proportion of individual not in favor.

In favor = 72%

Not in favor = 28%

Please help i don't understand this​

Answer:

A. x = (k + c)/4

Step-by-step explanation:

In this question, they're asking for what x equals in terms of k.

You know that 4x - c = k

add c on both sides, you get:

4x = k + c

divide 4 on both sides to isolate the x variable, you get

x = (k + c)/4

<em>It's a simple question when you think about it! If this helped, please mark it brainliest.....thank you....................</em>
