Answer:
The answer is explained below
Step-by-step explanation:
A. How many ways can you distribute 4 different balls among 4 different boxes
The number of ways in which 4 different balls can be distributed among 4 different boxes is 
B. How many ways can you distribute 4 identical balls among 4 identical boxes?
The number of ways in which 4 identical balls can be distributed among 4 identical boxes = P(4,1) + P(4,2) +P(4,3) + P(4,4) = 1 + 2 + 1 + 1 = 5 ways
Where P(k,n) is the number of partitions that k can be divided into n parts
P(4,1) = 4 = 1
P(4,2) = 1 + 3, 2+2 = 2
P(4,3) = 1 + 1 + 2 = 1
P(4,4) = 1 + 1 + 1 + 1 = 1
C. How many ways can you distribute 4 identical balls among 4 different boxes
The number of ways in which 4 identical balls can be distributed among 4 different boxes = 
The answer is four because there's one line that is placed on the origin which makes it no solution because there's not supposed to be a line on the origin and number 1 is a solution because there are neither lines plotted on the origin and has parallel lines
Answer:
B
14
I think it is right :D
Step-by-step explanation:
Answer: 1,4 is the answer
The answer is A, 8.94 seconds.
Since Gary ran 0.93 seconds faster than Brian, his time will have 0.93 seconds more than Brian's. To figure out Brian's time you have to subtract these 0.93 seconds from Gary's time.
9.87 - 0.93 = 8.94
I hope this helps!
