The average resident of a country uses 100 gallons of water per day the population of the country is about 3.23 x 10^8. About how many gallons of water do the countries residents use each day express your answer in scientific notation.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

the 3rd on is correct

step-by-step explanation:

one set of data has more variation than the other. hope this !
