Average of five numbers is 82 so their sum is 82*5 = 410. Average of four of them is 80, so their sum is 80*4 = 320. So the fifth number is 410 - 320 = 90.
Your average score would be 80.
Median is average so 80.

80% of 58 = 80% * 58 = 0.8 * 58 = 46.4
58% : 766 = 80% : n 58%n/58% = (766 * 80%)/58% n = 1056.55
80/82 = 40/41
If final is 25% of grade and your average was 82 before final that part is 75%. So we have (.75(82) + .25 (73)) = 80
The average temperature is between 80-82. This is according to Wikipedia. I also am a resident of Eugene.
