Answer:
0.75
Step-by-step explanation:
P(A | B) = P(A and B) / P(B)
P(vanilla | sundae) = P(vanilla and sundae) / P(sundae)
P(vanilla | sundae) = 0.15 / 0.2
P(vanilla | sundae) = 0.75
Explain what is meant by confounding. what is a lurking variable? what is a confounding variable?
Answer:
A Confounding is the variable that is considered in a research study, and could overall influence the relations between the variables in the study. For example, students wanting to join AP English next semester were told to write a six page essay. When the students turned in their papers and teachers say the difference and grades they believed that the variable was the time that the students handed in the paper. They thought that if the student handed in their paper later than another student that they would receive a lower score, but this was not the case. When asking the students how they prepared for the paper, students replied with different answers. Those who outlined and used other literature for reference scored much higher than those who only used prior knowledge to write their essays. In this study, the lurking variable would be the presence of an outline.
Lurking variable: A variable that is not considered in a research study that could influence the relations between the variables in the study
Confounding variable: A variable that is considered in a research study that could influence the relations between the variables in the study

Answer:
Ok tell me which mathematic game
Answer:
Missing x:0
Missing y:1
Hence, option b is correct.
Step-by-step explanation:
Given the table
x y
-9 3
-6 2
-3 missing
missing 0
As we know that the linear function has a constant common difference between the x values and y values.
From the table, it is clear that the x values have the same common difference, and the consecutive x values are separated by -3.
i.e. -9-(-6)=-3
-6-(-3)=-3
So the missing x value will be:
-3-(x)=-3
-3-(0)=-3
Therefore, the missing x value wil be: 0
From the table, it is clear that the x values have the same common difference, and the consecutive x values are separated by 1.
i.e.
3-2=1
2-y=1
y=1
Therefore, the missing y-value will be 1.
Therefore,
Missing x:0
Missing y:1
Hence, option b is correct.
