Answer:
6 miles(3 miles to your friend's + 3 miles back home) Step-by-step explanation:
a. What is the distance traveled by the skier during the three minutes of recreation? 360 mAdd the lengths of the three segments - 160 m + 120 m + 80 m. b. What is the net displacement of the skier during the three minutes of recreation? 120 m, EastMeasure from the starting point (A) to the ending point (D); include direction since displacement is a vector. c. What is the displacement during the second minute (from 1 min. to 2 min.)? 120 m, WestThe second minute corresponds to a movement from B to C. Measure from the starting point (B) to the ending point (C); include direction since displacement is a vector. d. What is the displacement during the third minute (from 2 min. to 3 min.)? 80 m, EastThe third minute corresponds to a movement from C to D. Measure from the starting point (C) to the ending point (D); include direction since displacement is a vector.
Answer:
Matched samples
Step-by-step explanation:
A matched sample is obtained when pairing of treatment values for each subject or observation is performed. This sample obtained from a matched pair is usually called dependent sample and is usually done when each subject in an experiment is subjected to two different treatments usually at different time or stage. Hence, matched samples are used in matching observations to tie different groups.
Answer:
25 units.
Step-by-step explanation:
r = 12 o = 2pi/3 (120°)
arc length = o/360° × 2pir
= 120°/360° × 2(22/7)(12)
= 1/3 × 2(22/7)(12)
= 2 × 22/7 × 4
= 25 units to the nearest whole number.
