Since the order of selection does not matter we will use combinations to solve this problem.

Total number of students = 20
Number of students to be selected = 4

We are to find the combinations of 20 objects taken 4 at a time. This can be expressed as 20C4

20C4 = 4845

Thus, there are 4845 ways to select the 4 students.

So, the correct option is D

Answer:

x = 55

Step-by-step explanation:

Draw a line parallel to the top and bottom parallel lines so this new line goes through the pointed end of x.

Draw another line parallel to the top and bottom lines through the pointy end of 45.

The bottom angle of the line through 45 is 15 degrees (alternate interior angles.

The top angle is 45 - 15 = 30

The bottom angle of the line going to x is 150 degrees. It and the 30 degree angle make 180. 30 + 150 = 180

One final observation The top angle of made by the line going through x is 180 - 25 = 155

What you have now is

155 + 150 + x = 360

305 + x = 360

x = 360 - 305

x = 55
