Step-by-step explanation:

Let the number of students be = x

Hall A Total Cost

Relationship Equation, where TC (A) = f (students) = f (x) 40 per person (student) = 40x

Hall B Total Cost

Relationship Equation, where TC (B) = f (students) = f (x) 500 fix fee & 20 per person (student) = 500 + 20x

borishaifa [10]

Answer:

495 combinations of 4 students can be selected.

Step-by-step explanation:

The order of the students in the sample is not important. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

How many combination of random samples of 4 students can be selected?

4 from a set of 12. So

$C_{n,x} = \frac{12!}{4!(8)!} = 495$

495 combinations of 4 students can be selected.

Simplify algebraic expression 3/4 (1/2X - 12) + 4/5

Nata [24]

$\frac{3}{4} ( \frac{1}{2} x-12)+ \frac{4}{5} =$

$=\frac{3}{4} ( \frac{x}{2} -12)+ \frac{4}{5}$

$= \frac{3x}{8} -9+ \frac{4}{5}$

$= -\frac{41}{5} + \frac{3x}{8}$

The answer is: $-\frac{41}{5} + \frac{3x}{8}$
