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.

What is the slope-intercept form of the linear equation 4x + 2y = 24? Drag and drop the appropriate number, symbol, or variable
Morgarella [4.7K]

The slope-intercept form of the linear equation 4x + 2y = 24 is y =-2x+12

Step-by-step explanation:

We need to write slope-intercept form of the linear equation 4x + 2y = 24

The standard equation of slope-intercept form is:

y=mx+b

Converting given equation in slope-intercept form.

4x + 2y = 24

Add -4x on both sides

2y = -4x+24

Divide both sides by 2

y =-2x+12

So, the slope-intercept form of the linear equation 4x + 2y = 24 is y =-2x+12
