3,150 doesn't need to be simplified. so, i guess if it were to be simplified, it would just stay the same.
If you are finding the sample space see if it is biased or not. and if it population then find the experimental or theoretical.
26. y= -7/3+ 0 or just y= -7/3
27. y= -10
The unknown is the distance in kilometres
The given is the distance in miles=140 miles
1 mile=1.6093km
140 miles=?
140/1*1.6093km=225.302km
Therefore the 140 miles in km is 225.302km
