Answer:
612 adults
361 students
Step-by-step explanation:
To solve this question, set two equations:
Let x be number of adults and y be number of students.
As there are in total 937 people, the equation would be the sum of both adults and children:
...... ( 1 )
As the total sale amount is $1109, the equation would be to add up the ticket fee:
...... ( 2 )
Put ( 1 ) into ( 2 ):
Put y into ( 1 ):
Therefore there are 612 adults and 361 students.
The best possible solution for this item is to determine the permutation of 8 taken 3 since there are 3 positions and 8 people are qualified. We will use permutation instead of combination because of the specificity of the positions. That is,
8P3 = 336
Thus, there are 336 ways in which the officers can be selected.
Between 2² and 3².
2√5 is gonna be a little greater than 2*2, or 4. But definitely less than 3², or 9
