Answer:

The student is expected to spend <em>15.4 hours </em>doing homework

Step-by-step explanation:

The scattered plot shows there is a close correlation between the variables. A line of best fit will go through the 'center' of the points. Since we are not required to find an exact line, we'll draw it in red color as shown below

To know the equation of that line, we must take two clear points of it from the graph. We'll pick (28,4) and (4,25)

The equation of a line, given two points (a,b) and (c,d) is

$\displaystyle y-b=\frac{d-b}{c-a}(x-a)$

Using the selected points

$\displaystyle y-4=\frac{25-4}{4-28}(x-28)$

Simplifying and computing results, the equation is

$\displaystyle y=-\frac{7}{8}x+\frac{57}{2}$

Using that equation, we can predict how many hours the students will spend doing homework if they spend 15 hours watching TV

$\displaystyle y=-\frac{7}{8}(15)+\frac{57}{2}$ =15.4 hours

So the student is expected to spend 15.4 hours doing homework

Patrick wants to buy a rug for a section of his living room. When he approaches a rug vendor, which measurement would be most ap

Kazeer [188]

Usually, rugs have a rectangular shape, therefore the section of the living room that Patrick wants to cover is a rectangle.

The area of a rectangle can be found by multiplying the length and the width of the rectangle:
A = l × w

Hence, the most appropriate measurements Patrick should provide are the length and the width of the section of his living room he wants to cover.

How much fencing will John need? Use 22/7 for x.

Serjik [45]

Well 22/7 is 3.14 and so on but since there is a little more than 3 you need to make sure he covers up all the fencing places... SO John will need 4 fences
