Answer: Simple Random
Step-by-step explanation:
- A simple random sampling technique is a random sample technique in which a subset of the population is drawn by the researcher . They are chosen in such a way that all the individuals in the population has an equal chance to get chosen .
Given : In a study, the sample is chosen by pulling 50 names from a hat .

Thus, this is a simple random sampling method.
Step-by-step explanation: 3
Answer:
9 years.
Step-by-step explanation:
For 50 raccoons the equation is
0.4x^2+2x+2 = 50
0.4x^2+2x - 48 = 0
x = [-2 +/- sqrt(2^2- 4* 0.4*(-48)] / (2*0.4)
= (-2 +/- sqrt 9) / 0.8
= 8.74 , - 13.75 (ignore the negative).
So it's 9 years.
The value of this is 12.32
