In this problem, we have been given your grades in each of four categories, and we are given the weight of each of these categories, and we need to determine your final grade in the course as a percentage, accurate to two decimal places.
00:14
So what we actually want to determine in this case is the weighted meet, and that is given by summation wx divided by summation w, where w represents the weights and x represents the scores.
00:28
So let's find that.
00:31
So first of all, note that tests are worth 25%.
00:35
So the weight for test is 25%, that's 25 by 100 or 0 .25.
00:40
And we multiply this with x, which is the corresponding score, and you get 89 % on tests.
00:45
So 89%, that's 0 .89.
00:48
And we have summation over here.
00:49
So we add with this the next product of the form w times x.
00:53
Now, labs are worth 6%.
00:55
So the weight is 6%.
00:56
That's 0 .06...
