Answer:
i would say A. a convenience sample that is not representative of all first-year college students. there are more than 20 first-year college students in the world so obviously only talking to 20 of them won't be representative of /everyone/

Answer:
7 cm, 16 cm, 19 cm
Step-by-step explanation:
Let s represent the length of the shortest side in cm. The longest side is 3s-2, and the other side is 2s+2. The perimeter is the sum of the side lengths.
P = s + (3s -2) +(2s +2)
42 = 6s . . . . . simplify, use the given value of perimeter
7 = s . . . . . . . divide by 6
2s+2 = 16
3s -2 = 19
The side lengths are 7 cm, 16 cm, and 19 cm.
Solve for k by simplifying both sides of the equation, then isolating the variable .
Answer - K=5
Hope this helps!
