Please help!!! It would be much appreciated
BigorU [14]

Answer:

Hours of television because it is the explanatory variable.

Step-by-step explanation:

For me, I am assuming the more time spent watching television would cause lower reading scores. I imagine this would be a bar graph, the vertical y-axis would be labeled the reading scores and the horizontal x-axis would be the amount of hours spent watching television. This is because when you graph, you move right then up to get to the unit, meaning the hours of television affect the reading scores. hope this helpss

The area of a rectangular wall of a barn is 300 square feet. its length is 10 feet longer than twice its width. find the length
Savatey [412]

<span><span>L * W = 300 sq ft
</span><span> Length is 10 ft greater than twice the width.
L = 2W + 10
Substituting
(2W+10)*W = 300
2W^2 + 10W = 300
Divide both sides by 2
W^2 + 5W = 150
W^2 + 5W - 150 = 0
Factor
(W +15)(W -10) = 0</span></span>

<span>
<span> Roots are W=-15 and W=10.
A negative width is impossible, so W=10
L = 2W + 10
L = 2(10) + 10
L = 30</span></span>

 length = 30 feet, width = 10 feet

<span> Check: 30*10 = 300</span>
