Question

x= 10,15,25,12,20
F= 2,3,5,2,y
Given G.M= 17.15.
then explain how the value of y is 2.03 or 2??

Answer 1

Answer:

n=2+3+5+2+y

=12+y

G.M=(12+y)√((10*2)*(15*3)*(25*5)*(12*2)*(20*y))

17.15=(12+y)√((54000000)*y)

log(54000000y) to the base (17.15)=12+y

ln(54000000y)/ln(17.15)=12+y

(ln(54000000)+ln(y))/ln(17.15)=12+y

(ln(54000000)/ln(17.15))+(ln(y)/ln(17.15)=12+y

6.28+ (ln(y)/ln(17.15))=12+y

ln(y)/1.23=5.72+y

ln(y)-y=7.03
