When we add rational numbers we simply add or subtract the fraction or part of a whole so in this particular equation we would subtract 1 from 4 because adding a negative means the same thing. We then subtract 2/3 from 3 and get 2 1/3 Comment below if more details are required
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:
a- Slope-intercept form (y =
+
) ::=> 1
b- Slope of Line = m =
: From Equation 1
Step-by-step explanation:
a- We have following equation:
7x + 6y = 5
Here if we re-arrange for y:
6y = 5 -7x :: Compare it with y = mx + b
y =
+ 
b-Compare y = mx + b and y =
+ 
m= -7/6 and Slope of lines parallel to the given line is shown in the equation
