Answer:

15.

Step-by-step explanation:

Please consider the complete question.

You have to answer 2 essay questions for an exam. There are 6 essays to choose from. How many different groups of 2 essays could you possibly choose?

We will use combinations formula to solve our given problem.

The number of combination of n terms r terms chosen at a time is given by formula:

C(n,r)=\frac{n!}{r!(n-r)!}

C(6,2)=\frac{6!}{2!(6-2)!}

C(6,2)=\frac{6*5*4!}{2*1*4!}

C(6,2)=\frac{6*5}{2}

C(6,2)=3*5

C(6,2)=15

Therefore, there are 15 different groups of essays could you possibly choose.

Sunny_sXe [5.5K]

Answer: $96.15

Step-by-step explanation:

If you study an extra 10 hours per week, for 52 weeks, in total you studied 52 times 10 hours, this is:

52*10 h = 520h hours.

Now, for these 520 hours of hard work, you earn a scholarship valued (in total) at $50,000.

Then how much is worth each one of these 520 hours?

Let's take divide the value of the scholarship evenly into the 520 hours:

$50,000/520h = $96.15.

This means that the hourly return is $96.15
