Andreas93 [3]

The different councils consisting of 5 freshmen and 7 sophomores are possible 9216.

We have given that,

A pool of possible candidates for a student council consists of 14 freshmen and 8 software.

We have to determine the how many different councils consisting of 5 freshmen and 7 sophomores are possible

<h3>What is the combination?</h3>

$_n C_r=\frac{n !}{r ! (n-r) !}_n C_r = number of combinations\\\n = total number of objects in the set\\\r = number of choosing objects from the set$

The total number of the council is

$_{10} C_5\times _9 C_7$

=252(36)

=9216

The different councils consisting of 5 freshmen and 7 sophomores are possible 9216.

A stray dog ate 30 muffins. That was 3/4 of all of them. How many did you start with?

Alona [7]

For this equation the dog ate 3/4 of the 30 muffins. You would have started with 40 since the dog ate 3/4. So, the dog ate 3/4 muffins, and you would have 10 remaining.

Please let me know if this was right! Thanks!
