Determining if the method of randomization is either <u>appropriate</u> or <u>not</u> for each given situation includes:
A. Inappropriate
B. Appropriate
C. Appropriate.
<h3>What is randomization?</h3>
Randomization is the process of assigning research participants by chance to separate treatment groups.
Using a random drawing to assign subjects to groups and <u>flipping a fair coin</u> to assign participants to the experimental or control groups are instances of randomization.
Thus, the randomization method for experiment A is inappropriate, unlike experiments B and C.

Answer:
This is a geometric sequence.
Answer:
v = 85/t
Step-by-step explanation:
Velocity is the change in displacement of a body with respect to time. It is expressed as
velocity = displacement/time
v = d/t
Given
d = 85km
t = t
Substitute tis parameters into the function;
v = 85/t
Hence the velocity v as a function of travel time t in hours is expressed as;
v = 85/t

Answer:
15.2%
Step-by-step explanation:
There are 12 marbles in total and there are 5 red marbles, so the probability of getting a red marble is 5/12. There are now 11 marbles and there are 4 blue marbles. So the probability of getting a blue marble is 4/11.
You multiply these 2 values together.
5/12 * 4/11 = 20/132 = 0.1515
This is about 15.2%
