(1.35)(27)= 36.45(0) = 0 (13) = 13
Answer: The proportion of oil tankers that had spills is
or 0.329.
Step-by-step explanation:
Since we have given that
Number of tankers is drawn = 474
Number of tankers did not have spills = 318
Number of tankers have spills = 474 - 318 = 156
Proportion of oil tankers that had spills is given by

Hence, the proportion of oil tankers that had spills is
or 0.329.
Because GH bisects FGI, FGH=HGI
2x+1=3x-9
x=10°
so the measure of HGI is 21°
