Answer is 15 combinations of 2 people from 6 will be able to sit on front row.

The formula used is Formula for Combinations.
Where N = Objects equal to 6 people
and r = Sample or 2 Samples

We are to form the combination of 6 objects taken 2 at a time. This can be expressed as 6C2

$6C2= \frac{6!}{2!*4!} \\ \\ 
= \frac{6*5}{2} \\ \\ 
=15$

This means, there can be 15 different combinations of 2 members that can sit in the front row.

So, the answer to this question is option A

Find the domain for each expression. (1/x)+5<br> 1/x<br> X+5/x+5<br> X^2/x<br> 7/(x-2)

Using it's concept, it is found that the domain for the expressions is, respectively, given by:

$x \neq 0, x \neq 0, (-\infty, \infty), (-\infty, \infty), x \neq 2$

<h3>What is the domain of a function?</h3>

It is the <u>set that contains all possible input values</u>.

In a fraction, the denominator cannot be zero, hence:

The domain of the first two expressions is of $x \neq 0$ .

The domain of the last expression is of $x \neq 2$ .

The third expression can be simplified, as:

(x + 5)/(x + 5) = 1.

The same is true for the fourth, as:

x²/x = 1.

Neither has any restriction, hence their domain is all real numbers, represented by $(-\infty, \infty)$ .

Answer:

$\sqrt{\frac{9}{4}}$ < $\frac{5}{3}$ < $\sqrt{5}$ < 2.5

Step-by-step explanation:

Given the following numbers, $\sqrt{\frac{9}{4}}, \sqrt{5}, 2.5, and, \frac{5}{3}$ , let's express each as whole or decimal numbers, to find out the least to the greatest.
