Answer: Our required probability is 0.11.
Step-by-step explanation:
Since we have given that
Number of workers in first shift = 21
Number of workers in second shift = 15
Number of workers in third shift = 13
We need to find the probability of choosing exactly two second shift workers and two third shift workers.
So, it becomes,

Hence, our required probability is 0.11.

Answer:
y=b-a/x
Step-by-step explanation:
yx+a=b
-a
yx=b-a/x
Answer:
A’ (6,-2)
B’ (1,3)
Step-by-step explanation:
Here, we want to give the coordinates after a counterclockwise rotation of 90 degrees
Given a point with coordinates (x,y)
A counterclockwise rotation at 90 degrees to the origin will yield the coordinates (-y,x)
So A (-2,-6) will be A’ (6,-2) while B (3,-1) will be B’ (1,3)
Answer:
A = $4360.515918 which rounded to the nearest penny is $4360.52
