Answer:
2520 ways
Step-by-step explanation:
We can solve this problem with 3 combinations:
First the teacher needs to give 3 fruit snacks to 10 students, so we have a combination of 10 choose 3: C(10,3) = 10! / (3! * 7!) = 120
Then, she needs to give 2 teddy grahams to 7 students (3 already got a snack), so a combination of 7 choose 2: C(7,2) = 7! / (2! * 5!) = 21
The, she gives the 5 granola bars to the other 5 students, so a combination of 5 choose 5: C(5,5) = 1.
Now we just need to multiply the combinations to find the result:
C(10,3) * C(7,2) * C(5,5) = 120 * 21 * 1 = 2520 ways
Answer:
c(n) = 4n +20
let m = c(n)
m= 4n +20
make n the subject
<u>m</u><u> </u><u>-</u><u>2</u><u>0</u><u> </u><u> </u> =n
4.
inverse function of c(n)= <u>n-20</u><u> </u>
4
It is a must that one replaces the m with the n in order to get the final answer
