A permutation is where there is a difference in positions where the things will be selected into (order matters). Combination is where order doesn’t matter. I have sorted them but I am not sure about the starting line up one. If the players are selected into specific positions then it would be a permutation.
Irrational
the number is endless in its digits (much like pi) and thus is irrational
Answer:
Step-by-step explanation:
Given that the dollar cost of producing x appliances is

A) Average cost can be obtained by dividing c(x) by units = x
i.e. average cost = 
B) Marginal cost = dC/dx = 
When x=140 marginal cost 
C) We calculate
c(140) = 
c(141) = 
Marginal cost = difference = 33.80
Same as 34 shown in marginal cost.
Form an equation using the information provided
x = number
(x + 5)/9 = 3
multiply by 9
x + 5 = 27
then solve
x = 22
