Kayla has taken six history quizzes so far, earning the following scores. 7, 8, 8, 8, 10, 9 What score would Kayla have to get on the seventh quiz in order to have a mean score of 8? 9 8 7 6

Respuesta :

The answer would be six because if you add them up it would equal 56 then divide that by 7 gives you a mean of 8. hope that helps
You want a 8 and there's 7 quizzes so you need 56 pts

7+8+8+8+9+10=50 already have
56-50 =6
You need 6 pts
