Number of people in the office=13
Number of office lines=66
Given that all the 6 phones started ringing at once, the number of groups of 6 people that that can answer the lines will be:
13C6
=(13!)/(6!7!)
=1,716

Answer:
Step-by-step explanation:
Given:
From the graph, the x and y intercepts are at the points (3, 0) and (0, 1) respectively.
Now, for a line with two points , the slope is given as:
Here, . Therefore,
Now, y-intercept is
Therefore, the standard form of a line is of the form: . So, the equation of the line on the graph is:
Now, from the graph, the region is below the line including all the points on the line. Therefore, the inequality used is less than or equal to. This gives,
