In this problem, we're provided with the students ' grades, and we're asked to find what the students ' the student's weighted mean grade point score is.
00:12
So we know that we're going to need the weighted mean formula for this question.
00:21
And that looks like this.
00:24
I'm going to do w weighted mean equals the sum of w.
00:35
The weight times the number, so w times x, divided by the sum of w.
00:49
And let's go ahead and break this formula down.
00:54
Let's start by creating a table with the information provided to us.
01:00
So we know that the student received, let's go ahead and break it down by grades.
01:11
Otherwise in our formula known as x, and we also know from the question we know that we also have the amount of credits that each class is worth so credits which in for the formula will be w the weight so each the weight of each class so once we jot this down we know that he received an a in a three credit class he received a b in two four credit class he received a b in two four credit classes.
01:55
So that means he got two bs.
02:00
And i'm going down, i'm going down this line here first.
02:04
Next, we're going to, we know he got a c in one three credit class.
02:11
And finally, a d in one two credit class.
02:16
So this class was worth two credits.
02:19
Okay.
02:19
And now what we have to input, take into consideration is the first part here that was provided to us.
02:26
We have to know how much.
02:28
Each letter grade how many points they're worth.
02:32
So an a is worth four points.
02:39
Let's do four points.
02:43
A b is worth three points.
02:53
A c is worth two points...
