William is taking the 25-question, multiple choice American Mathematics Competition. Each question has five answer choices. Will
1 answer:
Given that <span>William guesses random answers for the last four questions and that e</span><span>ach question has five answer choices.</span><span>
The probability that he gets an answer correct </span>is 1 / 5.
The probability that he did not get an answer correct is 4 / 5.
The probability that he will not get any of the 4 questions correctly is
Therefore, the probability that he gets at least one of the 4 questions correctly is

N is M reflected across the y-axis; only the signs of the x-coordinates of M and N are different.
<u>Step-by-step explanation:</u>
In question no statements are available , below statements are the required one:
- N is M reflected across the x-axis; only the signs of the x-coordinates of M and N are different: N is reflected over y-axis not x-axis so, this option itself is wrong!
- N is M reflected across the x-axis; only the signs of the y-coordinates of M and N are different: N-M is reflected over y-axis not x-axis , so this option is also wrong.
-
N is M reflected across the y-axis; only the signs of the x-coordinates of M and N are different: N-M are reflected over y-axis correct and sign of only x co-ordinate is changed as Co-ordinates are
and
.Hence, this statement is correct!
- N is M reflected across the y-axis; only the signs of the y-coordinates of M and N are different. N-M is reflected over y-axis , and sign of only x co-ordinate is changed not y . False statement.
We can see that point Correct statement is 3.
F(3) occurs when x =3. So lets plug 3 into our equation.
F(3) = -28
I hope this helps! :)
