Answer:
There are 795 combinations.
Step-by-step explanation:
The number of ways or combinations in which we can select k element from a group of n elements is given by:
So, if Miriam want to choose 3 movies with at least two comedies, she have two options: Choose 2 comedies and 1 foreign film or choose 3 comedies.
Then, the number of combinations for every case are:
1. Choose 2 Comedies from the 10 and choose 1 foreign film from 15. This is calculated as:
2. Choose 3 Comedies from the 10. This is calculated as:
Therefore, there are 795 combinations and it is calculated as:
675 + 120 = 795
X^4 - x^2 + 9 - (x^3 + 3x^2 + 12) =
x^4 - x^3 - 4x^2 - 3
Answer:
Step-by-step explanation:
6f - 1 + 7f - 8 = 6f + 7f - 1 - 8
= 13f - 9
Combine like terms. Like terms have same variable with same power.
Answer:
14
Step-by-step explanation:
we are solving 15 + |-3| - 4
anything inside | | means it's absolute value.
absolute value means that even if it is a negative number inside, it will change to positive. if it is a positive number inside, it will stay the same.
so |-3| is 3.
15 + 3 - 4
18 - 4 = 14.
we got the answer
Answer:
<u><em>21 yard line</em></u>
Step-by-step explanation:
Ok we start out on the 20 yard line, we need to add the yards together.
<em>We add the 6 to the 20:</em>

<em>Then we subtract the 8 yards from our new 26:</em>
26-8=18
<em>Then we add the 18 by 3:</em>
18+3=21
Therefore,
<em>The Answer is 21 Yard Line.</em>
