A technology habit that I practice today that I realize will not help me to be successful is playing games on my phone. It’s important to stop doing this because instead of playing a game I could be doing more helpful things, like reading a book.
Answer:
In Python:
num = int(input("Enter number: "))
maxn = num
while num >=0:
if num>maxn:
maxn = num
num = int(input("Enter number: "))
print("Largest: "+str(maxn))
Explanation:
Get input from the user
num = int(input("Enter number: "))
Initialize the largest to the first input
maxn = num
This loop is repeated until a negative input is recorded
while num >=0:
If the current input is greater than the previous largest
if num>maxn:
Set largest to the current input
maxn = num
Get another input from the user
num = int(input("Enter number: "))
Print the largest
print("Largest: "+str(maxn))

Answer:
- If a group of 9 kids have won a total of 100 trophies, then at least one of the 9 kids has won at least 12 trophies.
- If a person buys at least 400 cups of coffee in a year, then there is at least one day in which the person has bought at least two cups of coffee.
- The average of three real numbers is greater than or equal to at least one of the numbers.
Explanation:
1)
Suppose that each kid has less than 12 trophies
Total trophies = 100
Maximum trophies won by one kid = 11
total kids = 9
total number of trophies = 9 * 11 = 99 which contradicts the fact the total number of trophies are 100
2)
Suppose that person has less than 2 cups of coffee a day
Total cups of coffee = 400
he has bought at least one cup of coffee each day
which means
total number of cups of coffee = 1* 366 = 366 which contradicts the fact the person buys at least 400 cups of coffee in a year
3)
Average of three number = (a+ b+ c)/3
suppose that there are real numbers a, b, and c such that all three numbers are less than the average of the three numbers.
Let m be the average (a+b+c
)/3 = m. Then our assumption states that (a < m) and (b < m) and (c < m). By adding all the inequalities we get a + b + c < 3m. But m is defined to be (a+b+c)
/3 , so a + b + c = 3m. But now we have that 3m = a + b + c < 3m. So 3m < 3m which is an obvious contradiction. Thus our claim is true
