For the given situation we have a total of 259,459,200 permutations.
<h3>
How many permutations are?</h3>
First, how we know that it is a permutation?
Because the order matters, we aren't only selecting 8 out of the 15 people, but these 8 selected also have an order (is not the same thing to finish the race first than fourth, for example).
Then we need to find the number of permutations, to do it, we need to find the numbers of options for each of the 8 positions.
- For the first position there are 15 options.
- For the second position ther are 14 options (one runner already finished).
- For the third position there are 13 options.
- And so on.
Then the total number of permutations (product between the numbers of options) is:
P = 15*14*13*12*11*10*9*8 = 259,459,200

Answer:
45x-95
Step-by-step explanation:
Answer:
When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles. Example: a and e are corresponding angles. When the two lines are parallel Corresponding Angles are equal.
Answer:
g(2) = 2
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that 
Put x =2
= -1+3
= 2
g(2) = 2
Answer:
mean=12
Step-by-step explanation:
First, order the data like so.
5, 7, 12, 12, 16, 17, 17
Then add them all up.
It is a sum of 86.
Finally divide
86/7=12.2
Since 12.2 movies aren't possible, let's say the mean is 12
