Supplementary means they add up to 180
angle 1 = x
angle 2 = x + 166
so x + x + 166 = 180
2x = 14
x = 7
so angle 1 = 7 angle 2 = x + 166 = 173
Yes it describes only a parameter because <span>a numerical characteristic of a population, as distinct from a statistic of a sample was use. only 35 out of the 1200 accountants salary was used in calculating an average salary. it will be real if use all the number of accountant in calculating the average salary</span>

X=amount of apples bought. (in pounds)
y=amount of bananas boutht (in pounds)
We can suggest this system of equations:
x+y=3.8
1.9x+0.75y=5.84
We can solve this system of euqtions by substitution method.
x+y=3.8 ⇒ y=3.8-x
1.9x+0.75(3.8-x)=5.84
1.9x+2.85-0.75x=5.85
1.15x=5.84-2.85
1.15x=2.99
x=2.99/1.15
x=2.6
y=3.8-x
y=3.8-2.6
y=1.2
Answer: C. 2.6 pounds of apples; 1.2 pounds of bananas.
