Answer:
B
Step-by-step explanation:
A contrapositive statement is one that switches the hypothesis and conclusion of a conditional statement and negates both. In our hypothesis,
"If it is past 5:00 p.m., Megan’s office building is not empty", we shall break it into two statements and show the contarpositive of each like shown below.
Hypothesis Contrapositive
Megan’s office building is not empty- Megan’s office building is empty
It is past 5:00 p.m - it is not past 5:00 p.m
And thus the contrapositive statement becomes
If Megan’s office building is empty, then it is not past 5:00 p.m.

Step-by-step explanation:
If Brooke multiplied 3 by 9 and obtained 17 ; then Brooke is definitely wrong
3 * 9 = exactly 27
However, for approximation sake ;
We could round 9 to 10 ; and multiply 10 by 3
10 * 3 = 30 ; this gives an approximate solution for the multiplication problem ;
3 * 9 = exactly 27 or approximately 30
Just like every other problem, in math or any other subject, you take the
information you have, and the relationships you know between the information
you have and whatever you need to find, and use them together to find what you need. I noticed that you didn't mention what information you have.
In general, the circumference of a circle is (pi) times (the diameter),
or (2 x pi) times (the radius). For 'pi' you can use (22 / 7), or 3.142 ,
whichever is easier for you. Either one will get you close to the real
exact answer.
If you don't know the diameter or the radius of the circle, but you know
something else, like for example the area of the circle, then you've got
a slightly more complicated problem. I can't cover all possible problems
you may run into, because, as I pointed out earlier, you haven't described
what information you already have.
Answer:
x = 7 is repeated twice.
Hence, there is NO MORE unique input. We can not have repeated inputs.
Thus, the relation is NOT a function.
Step-by-step explanation:
Given the relation
- {(6, 8), (7, 10), (7, 12), (8, 16),
(10, 16)}
We know that a relation is a function that has only one output for any unique input.
As the inputs or x-values of the relations are:
at x = 6, y = 8
at x = 7, y = 10
at x = 7, y = 12
at x = 8, y = 16
at x = 10, y = 16
If we closely observe, we can check that there is a repetition of x values.
i.e. x = 7 is repeated twice.
Hence, there is NO MORE unique input. We can not have repeated inputs.
Thus, the relation is NOT a function.
