According to the scatterplot below, which statement is correct? A graph titled Courses Completed versus Remaining Credits Needed

kondaur [170]

Answer:

Option B.

Step-by-step explanation:

It is given that a graph titled Courses Completed versus Remaining Credits Needed to Graduate has courses completed on the x-axis and Credits need to graduate on the y-axis.

Points plotted are (4, 110), (8, 76), (16, 63), (20, 53), (24, 33).

Since, x-axis represents the courses completed, therefore the input, or independent variable is courses completed.

Since, y-axis represents the Credits need to graduate, therefore the output, or dependent variable is Credits need to graduate.

Therefore, the correct option is B.

7. Evaluate 4P2<br><br> O<br><br> 22<br><br> O<br><br> 12<br><br> O<br><br> 14<br><br> 5

Reika [66]

Answer:

<h2>12</h2>

Step-by-step explanation:

To evaluate 4P2, we will use the permutation formula as shown;

nPr = $\frac{n!}{(n-r)!}$

4P2 = $\frac{4!}{(4-2!}$

$= \frac{4!}{2!} \\= \frac{4*3*2!}{2!}\\ = 4*3\\= 12$

4P2 = 12
