<span>To answer this question, first find the percentage of eighth graders in the sample who chose football. To do this, take ratio of 16/56=.285 and rounding gives us .28 or 28%. Now, if we assume that the sample size reflects the attitudes of all the eighth graders in the school, we take 28% of the total number of eighth graders (495). Doing this we get .28 x 495 = 138.6 or rounding to get 139 students. 139 students are predicted to prefer football.</span>

Consider the equation. Which graph shows a line that is perpendicular to the line defined by the given equation? A. In a linear
Nikolay [14]

The graph second represents the line that is perpendicular to the line y = 4x - 2 option  (B) is correct.

<h3>What is the slope?</h3>

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

\rm m =\dfrac{y_2-y_1}{x_2-x_1}

The question is incomplete:

The complete question is:

Consider the equation y = 4x - 2 Which graph shows a line that is perpendicular to the line defined by the given equation?

Please refer to the attached picture.

The given line:

y = 4x - 2

The slope of the line m = 4

The slope of the line which is perpendicular to the above line:

M = -1/4 = -0.25

The graph second has a slope of -0.25

\rm y\ -2\ =\ \dfrac{\left(2-0.5\right)}{-4-2}\left(x+4\right)

y - 2 = -0.25x - 1

y = -0.25x + 1

Thus, the graph second represents the line that is perpendicular to the line y = 4x - 2 option  (B) is correct.

Ted can clear a football field of debris in 3 hours. Jacob can clear the same field in 2 hours. When they work together, the sit
Rasek [7]

Answer:

If Ted can clear a football field of debris in 3 hours, in one hour they will have cleared 1/3 of it.

If Jacob can clear a football field of debris in 2 hours, in one hour they will have cleared 1/2 of it.

So if they work together, they will clear 1/2 + 1/3, which is 5/6, in one hour.

So the equation we get is 5/6*x = 1 and if we divide both sides by 5/6 we get that x = 1.2 hours
