No. This is not random sampling as the students chose are not chosen at random. Random sampling would be something done where each sample has equal probability of being chosen. Clearly this is not random sampling.
Answer:
π/90 or 0.0035 units
Step-by-step explanation:
equation: <em>length of the arc = ∠of the angle/360 * circumference</em>
Substitute: <em>S = 0.4/360 * 10π</em> --> C = 2πr
Simplify: S = 1/900 * 10π
Simplify: S = π/90 ≈ 0.003489 units
Add 4/10 to 9/10.
9/10 + 4/10 = 13/10
Simplify 13/10 into a mixed number by subtracting 10 from the numerator and turning it into a whole.
13/10 ⇒ 1 3/10

Answer: the trip is 127 1/5 miles
Step-by-step explanation:
The distance that the martinez family drove from home to the ski lodge is 45 4/5 miles. Converting 45 4/5 miles to improper fraction, it becomes 229/5 miles.
Then, they drove an additional 17 4/5 miles to there friends house. Converting 17 4/5 miles to improper fraction, it becomes 89/5 miles
This means that the total distance that they drove while going is
229/5 + 89/5 = 318/5 miles
If the family drove the same route back home, then the distance traveled during there trip is
2 × 318/5 = 636/5 miles
Converting to mixed fraction, it becomes
127 1/5 miles
