Answer:
Step-by-step explanation:
If the mean of 15 students is 71.5, then total score = 15 X 71.5 = 1072.5
The median score is 62, meaning that, the combined score of two students = 62 X 2 = 124
The difference of 1072.5 and 124 = 948.5, this represents the total score of 13 other students
∴ The mean score of 13 students = 948.5/13 = 73
In conclusion, it was only very few students that took the exam and majority of other students absconded from the exam. Majority of students scored averagely above 70.

Answer:
Final answer is $9000.
Step-by-step explanation:
Given that Alice took out a $15,000 loan for college. She is borrowing money from two banks. Bank A charges an interest rate of 6%, and Bank B charges an interest rate of 7%. After one year, Alice owes $960 in interest.
Now we need to find out about how much money did she borrow from Bank A.
So let's assume that money borrowed from bank A = x
then money borrowed from bank B = 15000-x
Interest from bank A = 6% of x = 0.06x
Interest from bank B = 7% of (15000-x) = 0.07(15000-x)
Given total interest is $960. So we can write equation:
0.06x+0.07(15000-x)=960
0.06x+1050-0.07x=960
1050-0.01x=960
-0.01x=960-1050
-0.01x=-90
x=9000
Hence final answer is $9000.
