Answer 3

Calculation of the Number of Segments

To find the number of segments formed by 10 points on a line, we can use the formula for combinations. The formula for combinations is given by:

nCr = n! / (r! * (n-r)!)

Where n is the total number of points and r is the number of points chosen to form a segment.

In this case, we have 10 points and we want to find the number of segments formed. To form a segment, we need 2 points. Therefore, r = 2.

Substituting the values into the formula, we get:

10C2 = 10! / (2! * (10-2)!)

Simplifying the expression:

10C2 = 10! / (2! * 8!)

10C2 = (10 * 9) / (2 * 1)

10C2 = 45

Therefore, the number of segments formed by 10 points on a line is 45.
