Answer:
z=100
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary.
180-80=100
Insert x = 100 and x = 200 in the function
f(100) = 20,000 - 40*100
= 20,000 - 4000
= 16,000
f(2)) = 20,000 - 8,000 = 12,000
So its choice C , All reals between 12,000 and 16,000 inclusive.
The answer is
B.) As x approaches negative infinity, f(x) approaches positive infinity.
Answer:
A: undercoverage bias
Step-by-step explanation:
Undercoverage bias occurs in a study or sampling when some elements of the sample population are not represented or inadequately represented.
In this case study, random sampling using phone book will not adequately represent the true size of the population since 4% have no phone, and 15% have unlisted home numbers, while only 10% have only cell phones. This sampling suffers from undercoverage bias
150 * 12 = 1800. 18 * 160 = 3040. 3040 - 1800 = 1240. 1240 / 6 = 206.6666666666.
