Answer:
B- It cannot be answered without additional information.
Step-by-step explanation:
From the question, we have α= 0.01 and α= 0.05.
Thus;
We can decide to look at the critical values and check if test statistic is less or more than the tabulated value for α= 0.01 and 0.05.
However, that will not be sufficient as neither the level of significance nor confidence level is clearly mentioned in the question and thus, we can not answer it without additional information.
AB and BC form a right angle at their point of intersection. This means AB is perpendicular to BC.
We are given the coordinates of points A and B, using which we can find the equation of the line for AB.
Slope of AB will be:

Using this slope and the point (2,1) we can write the equation for AB as:

The above equation is in slope intercept form. Thus the y-intercept of AB is 4/3.
Slope of AB is -1/6, so slope of BC would be 6. Using the slope 6 and coordinates of the point B, we can write the equation of BC as:
y - 1 = 6(x - 2)
y = 6x - 12 + 1
y = 6x - 11
Point C lies on the line y = 6x - 11. So if the y-coordinate of C is 13, we can write:
13 = 6x - 11
24 = 6x
x = 4
The x-coordinate of point C will be 4.
Therefore, the answers in correct order are:
4/3 , 6, -11, 4
If you would like to know what do the f(x) and x represent in Luke's situation, you can find this using the following step:
<span>f(x) = 7x + 15
</span>7 hours each week
x ... the number of weeks
f(x) ... the total number of hours Luke exercises
The correct result would be A) <span>f(x) represents the total number of hours; x represents the number of weeks he exercises this summer.</span>
