In a class of 25 students, the average score is 84. Six students in the class each recieved a max score of 100, and 3 students each recieved a score of 60. What is the average score of the remaining students?
84=sum/25 6(100)+3(60)+x=sum find the sum from 1st equation then use it to find x in the 2nd question
I do not understand the first equation. sum of what?
sum of the marks for all the students in the class average=sum of items/number of items 84=sum/25
so 84/25?
sum=84*25
are we together here we multiply both sides by 25\[84=\frac{Sum}{25}\] \[Sum=84*25=2100\]
ok 6(100)+30(60)+x=2100?
yes so x=?
-300?
jk sorry hold on its 3 not 30
x=1320
yes my mistake good x=1320, so what is this x is it our answer or what
no cant be
so look this is the sum of the students who where left out -remaining how many where they remember we used only 6+3 students
do I divide it by 16?
good ,yes thats it,that will be their average
ok. took me a while to get there haha i apprecite your help
