Answer:
Step-by-step explanation:
The probability that the man gets x out of 20 correct follows a Binomial distribution, so the probability is calculated as:
Where n is the number of identical experiments and p is the probability of success. In this case n is 20.
Additionally, if he has no ESP the probability that he predict correctly is 0.5, because he is only guessing.
Then, the probability that he gets x out of 20 correct is equal to:
Therefore the probability that he would have done at least 17 out of 20 well if he had no ESP is:
Where:
So, is equal to:
Answer:
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation we must first find the slope of the line
Slope of the line using points (−2, 6) and (2, 14) is
Now we use the slope and any of the points to find the equation of the line.
Equation of the line using point ( - 2, 6) and slope 4 is
We have the final answer as
