The answer would be 4 because your rounding to the whole. If your rounding to the tenth it would be 3.4
Consider the equation:

Subtracting '4' from both the sides of the equation, we get as


Squaring on both the sides of the equation, we get


Subtracting '2' from both the sides of the equation, we get

x=14
Since, An extraneous solution is a solution that arises from the solving process that is not really a solution at all. But, in this equation x=14 is the solution of the given equation.
Hence, it is not an extraneous solution.
Answer: Nancy = X , Anna = Y X rule is plus 8 and Y rule is plus 12
Step-by-step explanation:
Using it's concept, it is found that the marginal relative frequency for students who plan to attend college is of 82%.
<h3>What is a relative frequency?</h3>
A relative frequency is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are a total of 82 students, 67 of which plan to attend college, hence the relative frequency is:
f = 67/82 = 0.82 = 82%.
