Answer 1

Jordan got an 81% .

how to figure out mean: 66,79,81,82 .

Add 79 and 81, which is 160/2=80%
You'll so be able to figure this out, because Jordans percent grade has to be lower than 82, and higher than 79. Therefore, you'll have to come up with a number that is higher than 79, but lower than 81. and first you have to come up with a number that will equal to 160 when you add it by 79. so, 160-79 = 81% which is also known as Jordan's grade. therefore the answer is, 81% dot Hope this helped!!

Answer 2

The answer would be 93% because first we need to do the reverse of how to find the mean... 80 * 4 = 320 and so we just have to subtract the grades from 320... 320 - 79 - 66 - 82 = 93... Thus Jordan's grade was 93
