Luis’ sample would be the most random, because not everyone in the cafeteria might check out books from the library, but since everyone Samantha surveyed was in the library already, most of the people she surveyed would be more consistent in their responses.

Which of the following could be the function graphed?
Tpy6a [65]

Answer: The answer is (d)~f(x)=\dfrac{237x}{421x-515}.  


Step-by-step explanation: We are given four different functions of the variable 'x' and a graph. We are told to select one of the four options that which function can be graphed as the graph given in the question.

To check, we start plotting the functions one by one on a graph paper. We see that the graph of first three functions do not match with the given graph, but the graph of the fourth function given by

(d)~f(x)=\dfrac{237x}{421x-515}

matches exactly with the graph given in the question. The attached figure will show the graph for this function, which is exactly same as given.

Thus, the correct option is

(d)~f(x)=\dfrac{237x}{421x-515}

Answer:

416 mi

Step-by-step explanation:

In order to find the surface area, you must find the area of each square. There are a total of 6 that make up the prism.

<em>Remember to find the area it is length x width</em>

  1. 9 x 8 = 72 which is the area for 4 of the squares. 2 on the side and 2 on the bottom
  2. Lastly for the last 2 squares to find the area you multiply 8 x 8 = 64
  3. In total, you will add 72+72+72+72+64+64 which equals 416
