Question 884537
Suppose that the mean score of a class of 34 students was 77. The 17 male students in the class had a mean score of 70. What was the mean score for the 17 female students? Round to 4 decimal places.
***
let x=mean score for 17 female students
{{{(17*70+17x)/34=77}}}
1190+17x=34*77
1190+17x=2618
17x=2618-1190=1428
x=84
mean score for 17 female students=84
