There are 15,958,866 adults in a region. If a polling organization randomly selects 1235 adults without replacement, are the selections independent or dependent? If the selections are dependent, can they be treated as independent for the purposes of calculations? Are the selections independent or dependent? O A. The selections are dependent, because the sample size is not small relative to the population. O B. The selections are dependent, because the selection is done without replacement. OC. The selections are independent, because the selection is done without replacement. O D. The selections are independent, because the sample size is small relative to the population. If the selections are dependent, can they be treated as independent for the purposes calculations? O A. Yes, because the sample size is less than 5% of the population. O B. Yes, because the sample size is greater than 5% of the population. OC. No, because the sample size is greater than 5% of the population. O D. The selections are independent.

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Addition
