A polling company reported that 43% of 2286 adults said that they play football.

1 answer:

7 0

There are 2286 respondents. The 43% meant that out of 100 people there are 43 who plays football. So for the basis of 2286, there are 982.98 people who plays football. That's 0.43(2286). Since we are talking about people and there is no 0.98 person, we have to round down. So there are 982 people who plays football.

(192/2286)*100 = 8.4% plays hockey.

Identify the function in which y varies directly with x

ZanzabumX [31]

Answer:

y = kx

Step-by-step explanation:

You'll need to share the possible answer choices in all future posts.

A function in which y varies directly with x has the form

y = kx, where k is the constant of proportionality.

With more data, it'd be possible for you and me both to identify this constant.

The original line has the equation of y=-2x+8

enot [183]

The new equation of line that is perpendicular to the original that goes through the point (6, -1) in slope intercept form is $y = \frac{1}{2}x - 4$

<h3>Solution:</h3>

Given that original line has the equation of y = -2x + 8

We have to write a new equation that is perpendicular to the original that goes through the point (6, -1)

Let us first find slope of original line

The slope intercept form of line is given as:

y = mx + c ------ eqn 1

Where "m" is the slope of line and "c" is the y - intercept

On comparing the slope intercept form and given original equation, we get "m = -2"

Thus slope of original line "m" = -2

We know that product of slope of a line and slope of line perpendicular to it are always -1

slope of original line x slope of line perpendicular to it = -1

$\begin{array}{l}{-2 \times \text { slope of line perpendicular to it }=-1} \\\\ {\text { slope of line perpendicular to it }=\frac{1}{2}}\end{array}$

Let us find equation of line with slope m = 1/2 and passes through point (6, - 1)

Substitute $m = \frac{1}{2}$ and (x, y) = (6, -1) in eqn 1

$-1 = \frac{1}{2} \times 6 + c\\\\-1 = 3 + c\\\\c = -4$

Thus the required equation of line is:

Substitute "c" = -4 and $m = \frac{1}{2}$ in eqn 1

$y = \frac{1}{2}x - 4$

Thus the equation of line perpendicular to original line is found
