The first one x=3 and for the second one x=2.
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:

Step-by-step explanation:
Given
-- degree of freedom

Required
Determine the t-value
The given parameters can be illustrated as follows:

Where

So, we have:

To solve further, we make use of the attached the student's t distribution table.
From the attached table,
The t-value is given at the row with df = 28 and
is 3.673900
Hence, 
Answer:
If one is 1 5/8 and its cost is 16.99 and you need 5lb.
Step-by-step explanation:Than first you will take the 16.99 x 5 =84.95 dollars. Take that 1 5/8 x 5 = 8 1/8
So it would take 8 1/8 and 84.95$
