Answer:
Haruka's final exam score in chemistry is 87
Step-by-step explanation:
Given mean of data set = 84
given score
Astronomy 72
Biology 85
Physics 92
Chemistry ?
we have to find score of chemistry
let the score of chemistry be x
we know that mean is sum of data set divided by no of terms in data set
mean = sum of data set /no of terms in data set
number of terms in our problem is 4 (Astronomy,Biology,Physics,Chemistry)
sum of set
72+85+92+x = 249+ x
as mean is 84,
hence
84 = (249+ x)/4
=> 84*4 = 249 + x
=> 336 = 249 + x
=> 336 - 249 = x
=> x = 87
Thus, Haruka's final exam score in chemistry is 87.
