Prof Liu gave the same quiz to the students in her morning class and in her afternoon class. the average score for the two class
yaroslaw [1]

Answer:

Step-by-step explanation:

Given that Prof  Liu gave the same quiz to the students in her morning class and in her afternoon class. the average score for the two classes combined was 84.

(1) The average score for the students in the morning class was 80

(2) the average score for the students in the afternoon class was 86

Let m be the no of students in I class and n in II class

Total of I class = 80m and

Total of II class = 86n

Total of both classes = 80m +86n

Average =\frac{80m+86n}{m+n} = 84

m cannot be equal to n because in that case average would have been 83

If m >n, then say n =m+a

then average = \frac{80m+86m+86a}{2m+a} =84

Because 86 is more times added, average score would decrease hence we would not get 84.

So I class is getting less score of 80 to get a score average of more than 83 (the average) the class II should have more students.

Answer:

13 buckets

Step-by-step explanation:

To find the area of the closet, 7 x 10 x 9 = 630. The amount of square feet in the closet is 630. If one bucket of paint only covers about 100 square feet and he was recommended to do 2 coats, that means he will need to paint 1260 square feet total, including both coats. If one bucket covers 100 square feet, then he will need to buy 13 buckets of paint total.
