Answer:
second transformation is a reflection across the line containing AB
Step-by-step explanation:
The options are : a reflection across the line containing AB , a rotation about point B, a reflection across the line containing CB, a rotation about point C
The diagram is attached below
The triangle ABC is transformed to get triangle QRS
First transformation is the translation of vertex B to vertex R.
To get the same triangle QRS, the triangle to be reflected across the line AB
So second transformation is a reflection across the line containing AB

Answer:
46.91% probability that at least nine participants complete the study in one of the two groups, but not in both groups
Step-by-step explanation:
We use two binomial trials to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Probability of at least nine participants finishing the study in a group.
0.2 probability of a students dropping out. So 1 - 0.2 = 0.8 probability of a student finishing the study. This means that .
10 students, so
We have to find:
Then
0.3758 probability that at least nine participants complete the study in a group.
Calculate the probability that at least nine participants complete the study in one of the two groups, but not in both groups?
0.3758 probability that at least nine participants complete the study in a group. This means that
Two groups, so
We have to find P(X = 1).
46.91% probability that at least nine participants complete the study in one of the two groups, but not in both groups
