For each of the following, determine whether the group is a sample or a population. a. the participants in a study of a new cholesterol drug. b. the drivers who received a speeding ticket in kansas city last month. c. those on welfare in cook county (chicago), illinois. d. the 30 stocks that make up the dow jones industrial average.

:

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
