27/64 . because you do 3/4 to the third power (3x) which gives you that
We have been given in a cohort of 35 graduating students, there are three different prizes to be awarded. We are asked that in how many different ways could the prizes be awarded, if no student can receive more than one prize.
To solve this problem we will use permutations.

We know that formula for permutations is given as

On substituting the given values in the formula we get,


Therefore, there are 39270 ways in which prizes can be awarded.
Answer:
13
Step-by-step explanation:
15 - 4 + 7 - 5 = 13
Simply expand the brackets and subtract and add accordingly.
The expressions in which the numbers, or variables, or both, are connected by operational signs (+, - etc.) are called algebraic expressions. For example 5, 4x, a+b, x−y.
An expression that represents the perimeter of the rectangle would be:
P = 2(3n+2) + 2(n-1)
Hope this helps!
