Step-by-step explanation:
The number of way to select 2 employees from 40 is 40C2.
The number of way to select 2 employees from 22 is 22C2.
So the probability of the two employees having single-vision correction is just the number of ways to select the 22 employees (22C2) divided by the total number of ways to select 2 employees (40C2).
22C2 / 40C2 = 77/260
We can use the same technique for the bifocal employees.
18C2 / 40C2 = 51/260
Answer:
Line f has the same slope, -4/3
Step-by-step explanation:
First find the the slope of line e
m = (y2-y1)/(x2-x1)
= (2-6)/(10-7)
= -4/3
Since the lines are parallel, they have the same slope
Line f has the same slope, -4/3
