Answer:
m(arc FE) = 166°
Step-by-step explanation:
By theorem of intersecting chords and tangent of a circle,
Measure of the angle formed by a chord and tangent intersecting on the circle measure the half of the intercepted arc.
m(∠GFE) = 
83° =
m(arc FE) = 166°
3×9=27
27×7=189 units³

Answer:
a, b, c --- all <em>not</em> representative
Step-by-step explanation:
The question posed by the engineer is "are residents of the city in favor of ...".
The only representative sample is one from a pool that includes <em>all residents of the city</em>—not just those who (a) use the road, (b) live along the road, or (c) own homes.

<em>Additional comment</em>
The engineer may want to refine the question. As posed, it would include children, homeless, and/or institutionalized residents of the city as well as drivers and tax-payers. In inclusive cultural traditions, "residents of the city" may also include animals, plants, water, air, and other holders of spiritual energy.
Answer:
Step-by-step explanation:
Given that a friend flips a coin 10 times and observes head 7 times. So he concludes Probability of head =0.1
This is wrong because
i) Just making 10 trials and coming to conclusion is wrong. Trials should be large to get accurate estimate
ii) The way he threw the coin may be biased so differrent persons should flip and get results for larger trials
iii) External influences such as air, any other disturbance is not considered here.
To avoid all these sampling fluctuations number of trials should be increased with different situations and times.
