Description
Q1> a,b, and c are integers and a<b<c. S is the set of all integers from a to b, inclusive. Q is the set of all integers from b to c, inclusive. The median of Set S is (3/4)b. The median of set Q is (7/8)c. If R is the set of all integers from a to c, inclusive, what fraction of c is the median of set R?
Explanation & Answer
Thank you for the opportunity to help you with your question!
Median of S =(a+b)/2
3/4b = (a+ b)/2
3/2b = a+ b
a= 3/2b-b
a=b/2
Median of Q=(b+c)/2
7/8c = (b+c)/2
b+c= 7/4c
c= 7/4c-c
b= 3/4c
Median of R = (a+c)/2
but a= b/2
a= 3/4c/2
a= 3/8c
median of R = (3/8c +c)/2
= (11/16)c
