Answer:
And we have a sample size of n =81. We want to estimate the standard error of the sampling distribution 
and for this case we know that the distribution is given by:
And the standard error would be:
And replacing we got:

Answer:
takes him 8.4 hrs
Step-by-step explanation:
if 1/4=18inch then 3 1/2=7/2 so 7/2 divide by 1/4=14 then 18 x 14=252
so distance is 252 miles
speed is 30mph so 252/30=8.4h
the answer might need the 0.4 in hrs too
4x+6<-6
minus6 both sides
4x<-12
divide 4 both sides
x<-3
x is any number less than -3
try -100
4(-100)+6<-6
-400+6<-6
-394<-6
true
x<-3
