There are 30 days in the month of April.31 students will be celebrating their birthdays in that month
Can you find 2 student who were born on the same day? Why?
cảm ơn các bn rất nhiều, các bn làm đc bài nào thì chỉ mik zới nhé
Bài 1: First task:
Let \(x\) be the number of sparrows on the first lamp post at first. (\(x\) is a positive integer).
\(\Rightarrow16-x\)is the number of sparrows on the second lamp post at first.
We have: \(x-2+3=16-x+2-3\Leftrightarrow2x=14\Leftrightarrow x=7\)
Hence there are 7 sparrows on the first lamp post at first, 9 sparrows on the second lamp post at first.
Bài 2: Second Task
We can find 2 students who were born on the same day.
There are 30 days in April and 31 students were born on that month. Apply the Dirichlet 's theorem, we can ensure that threre exists at least one day where 2 students were born.
1. Mike jogs at constant speed along a road with lamp posts which are evenly spaced. It takes him 2 minutes to go from the first lamp post to the fifth lamppost. He continues jogging to the n-th lamp post before turning back. If he has been jogging for 12 minutes when he returns to the first lamp post, what is the value of n? ( Mike đi bộ với tộc độ không đổi trên đoạn đường có các cây cột đèn được đặt cách đều nhau. Mike cần 2 phút để đi từ cột đèn đầu tiên đến cột đèn thứ 5. Bạn ấy tiếp tục đi đến cột đèn thứ n trước khi quay ngược lại. Nếu tổng thời gian Mike đi bộ là 12 phút tính từ lúc bắt đầu đi đến khi quay lại đến cột đèn đầu tiên thì n bằng bao nhiêu?)
