Answer:
The game developer tested by 24 participants and these 24 participants were divided evenly between the treatments and the required total number of possible replications combinations is 4.
Step-by-step explanation:
<em>The Concepts and reason
</em>
The ANOVA can be used to analyze the data obtained from experimental or observational studies. A factor is a variable that the experimenter has taken for investigation.
A treatment is a level of a factor, and its experimental units are the objects of interest in the experiment. The variation between treatments groups captures the effect of the treatment and the variation within treatment groups represents random error not explained by the experimental treatments.
The replication means an independent repeat of each factor combination.
<em>Fundamentals
</em>
The formula for replications is: Number of participants/number of cells
The total number of participants is: 24
The number of cells is: 6
The total number of participants in the game is 24 and the number of possible combination cells is 6
so,
Number of replications: Number of participants/number of cells
which is 24/6= 4
Therefore the number of replications is 4.
Answer:
12 ways
Step-by-step explanation
First, we will count the number of ways to get three correct answers:
Notice there is a set of 4 correct answers (one per each one of the four questions in the test). We need to pick three of them. The order does not matter (for example: it is the same to have the arrangement of correct answers: Question 1 , Question 2 and Question 3, than having the arrangement: Question 2, Question 1 and Question 3). Therefore, we are dealing with combinations from a set of 4 elements forming groups of 3 elements:
Now we need to count the number of ways we can answer incorrectly the remaining fourth question:
We have a total set of 3*4 = 12 incorrect answers (three per each one of the four questions in the test). But notice that once we have picked three correct answers, then we should exclude from the set of incorrect answers we can pick, those of the three questions already answered. So, we are left with just the set of incorrect answers of the remaining question that has not been responded yet. Thus, we just have 3 incorrect answer to pick for the remaining question.
Then using the fundamental counting principle, we multiply the previous results:
Ways to answer correctly three questions * Ways to answer incorrectly the remaining question
Therefore, there are 12 ways to fill out the answer sheet so that three answers are correct and one is incorrect.
7p-(3p+4)=-2(2p-1)+10
7p-3p-4=-4p+2+10
collect the like terms
7p-3p+4p=2+10+4
8p=16
p=2
Answer:
1 answer is 30 2 answer is =

Step-by-step explanation:
Answer:
The answer is b.
Step-by-step explanation:
The line reflected with the axis only changes the position, and will not change the size. If reflected with y-axis, AB moves left of the y-axis lying x= -1 to x= -5.
A'B' will not be perpendicular unless you rotate at some point for 90 degrees.
