Is repetition permitted in permutations/combinations?

Yes repetition is permitting in permutations/combinations. It depends on the problem. For example a password being "555" is allowed. But in a race, racers logically can not repeat.

Step-by-step explanation:

i'm not entirely sure

step-by-step explanation:

if you ask home depot or lowe's they might be able to you out

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
