Answer:

The number is 5

Step-by-step explanation:

6+3n = 5n-4

Subtract 3n from each side

6 = 2n-4

Add 4 to each side

6+4 = 2n-4+4

10= 2n

Divide by 2

10/2 =2n/2

If 99 students had a mean quiz score of 82, how much is the mean score increased by the addition of a single score of 99? Explai
Leviafan [203]
The Mean would increase to 82.17 or a total increase of .17

You have 99 students and the avg is 82, therefore we can multiply 99*82 to get our total points

99*82=8118
We add a single score of 99 to our total points 8118+99= 8217

Then we add the student to the total number of students bringing it to 100 and divide our new total by the our new number of students. 
8217/100 = 82.17
