5^4 power. We can identify this because 5 is multiplying itself 4 times.
Hope this helps!
The first thing to do is to calculate how many ways you can choose 3 people from a set of eight. In order to do this, we need to use the attached formula.
(The letter 'n' stands for the entire set and 'r' stands for the number of objects we wish to choose.)
So we wish to choose 3 people ('r') form a set of 8 ('n')
combinations = n! / r! * (n - r)!
combinations = 8 ! / (3! * 5!)
combinations = 8 * 7 * 6 * 5! / (3!) * (5!)
combinations = 8 * 7 * 6 / 3 * 2
combinations = 56
Now of those 56 combinations, the 3 people can finish in 6 different ways.
For example, persons A, B and C could finish
ABC or ACB or BAC or BCA or CAB or CBA
So to get the TOTAL combinations we multiply 56 * 6 which equals
336 so the answer is (a)
It's 27 because two negatives cancels each other out.
Answer:
D
Step-by-step explanation:
So first you know that the angles are across for each other meaning that they are equal.
Therefore the equation would be 7x-13 = 48
Simply do order of operations meaning you subtract 13 from 48 giving you 35.
Then do 35 divided by 7 which means X equals 5 which makes it D.
