Answer:

D. about 40 miles

Step-by-step explanation:

In order to answer the question, you first need to find how many units on the graph Seaside is from Oceanfront - or how long the line between the two points is.

To do this, use the distance formula, $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ .

$x_1$ and $y_1$ represent the x and y values of one point, and $x_2$ and $y_2$ represent the x and y values of another point. Use the points of Seaside (by looking on the graph, you can see it's (-2,4)) and Oceanfront (also by looking, you can see it's (3, -2)) for the formula:

$d = \sqrt{((-2)-(3))^2+((4)-(-2))^2\\$

$d = \sqrt{(-2-3)^2+(4+2)^2}$

$d = \sqrt{((-5)^2+(6)^2\\$

$d = \sqrt{25 + 36} \\d = \sqrt{61}$

$\sqrt{61}$ units is about 7.8 units (you can also tell because it's in between $\sqrt{49}$ and $\sqrt{64}$ , which equal 7 and 8). Multiply that by 5 (since each unit on the graph represents 5 miles) and the answer is about 40. So, the answer is D.

Please find the complete question in the attachment file.

Throughout this question by acceptance of its zero hypotheses becomes equal to "the failure to accept the zero hypotheses." Its best answer is to refuse the null hypothesis or conclude how he had no effects on vibrant socks mostly on basis of this study, that's why the above given choice is correct.
