Hi there !
You have a formule. You just have to apply it.
Let's do it then !
First of all, you must write the coordinates of the point E and F.
Therefore :


So here, we have :




Now, Let's apply the formula :


In short, the answer would be : B)

.
Hope this helps !

Answer:
Its A
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have the following function:

2. You can rewrite it as following:

3. The line intersects the y-axis when
, therefore:

4. The line intersects the x-axis when
:

5. Now plot the points (0, 0.5) and (1,0) in a graph , as you can see in the figure attached.
Therefore, the answer is: The points of intersection are (0, 0.5) and (1,0).
First we need to arrange the numbers in this number set from smallest to biggest:17,18,24,27,31,39,42,47,55,65. Then there are 10 numbers in this number set. So when we calculate the median, we need to find the middle two numbers and calculate their average. So the median is (31+39)/2=35. SO the answer is B
